Suggested April 2024 Photoshop Cs6 New Features – Background Save And Auto Save
The second and more important new feature is Auto Save , which lets Photoshop CS6 save a backup copy of your work at regular intervals so that if Photoshop happens to crash while you’re working on an image, rather than losing everything you’ve done and starting over, you can recover the file and continue working from where you left off! In this tutorial, we’ll learn how both of these new features work.
Photoshop CS6 brings with it two great new features designed to improve your workflow and minimize annoying chúng tôi first of these new features, Background Save , lets Photoshop save your file quietly in the background so you can continue working on the image even as it’s being saved.Background Save
If you’ve been using Photoshop for a while, you know that as we add more and more layers to a document, we increase the file size. You probably also know that the bigger the file size becomes, the longer it takes Photoshop to save your work. With Photoshop CS5 and earlier, saving a large file often meant taking a break, whether you wanted to or not, because Photoshop would essentially freeze as the file was being saved, locking you out of the program and preventing you from doing anything more until the saving process was completed. Thanks to the new Background Save feature in Photoshop CS6, that’s no longer the case.
Here’s an image that I currently have open in CS6:
If we look in the bottom left of the document window, we see that the current file size is 121 MB, which is fairly small as far as Photoshop files go:
If we look in my Layers panel, we see that at the moment, my document contains only one layer, which is why the file size is relatively small:
With small file sizes like this, saving them isn’t a problem. The process happens so quickly that you barely notice it. Where the new Background Save feature in Photoshop CS6 begins to shine is when we start working with files that are hundreds of megabytes or more in size.
To see how it works, I’ll quickly increase the size of my file by making multiple copies of my image. To do that, I’ll press the keyboard shortcut Ctrl+J (Win) / Command+J (Mac) several times. Each time I press it, I make a new copy of the layer that the image is sitting on. Here we can see that my document now contains 8 layers – the original image on the Background layer, plus 7 copies above it:
When we look again in the bottom left of the document window, we see that my file size has increased from 121 MB all the way up to 967.9 MB:
Saving a file as large as this will take some time, and as I mentioned, in Photoshop CS5 and earlier, we would essentially be locked out of Photoshop and unable to continue working until the saving process was finished. Watch what happens, though, as I save the file in Photoshop CS6, which I’ll do by going up to the File menu in the Menu Bar along the top of the screen and choosing Save:
The first clue that something is different with CS6 is that Photoshop now shows us how far along we are in the saving process by displaying a couple of progress indicators. The first one can be found in the name tab at the top of the document window, where the progress is displayed as a percentage. Here, Photoshop is telling me that the save process is 34% completed:
The second indicator appears in the bottom left of the document window, and this one is a bit more helpful because along with the percentage value, it also displays the save process as a familiar blue progress bar:
While these progress indicators are a nice new addition to the interface, the real power of the Background Save feature in Photoshop CS6 is that, as its name implies, the saving process now takes place entirely in the background. What does that mean? It means that our workflow will no longer be interrupted when we go to save a large file because we won’t be locked out of Photoshop. We can continue working on the image even while it’s been saved!
As an example, here we can see that I’ve started working on a black and white conversion of my image (by adding a Black and White adjustment layer) even though the progress indicators at the top and bottom of the document window are telling me that the save process is still only 51% completed. The Background Save feature will even let us switch to a completely different image to work on while the original image is being saved, something that was not possible in Photoshop CS5 and earlier:Auto Save
A second and even more impressive new feature in Photoshop CS6 is Auto Save. Even though Photoshop has evolved into a very mature and stable program, there’s always the chance that something will go wrong and Photoshop will crash. When that happens, we often end up losing all the work we’ve done on our image, forcing us to start over again from scratch. At least, that’s the way things used to be back in Photoshop CS5 and earlier.
Auto Save allows Photoshop to save a backup copy of our work at regular intervals so that if Photoshop does happen to crash, we can recover the file and continue from where we left off!
We can tell Photoshop how often we want it to save a backup copy of our work in the File Handling section of the Preferences. On a PC, go up to the Edit menu at the top of the screen, choose Preferences, and then choose File Handling. On a Mac, go up to the Photoshop menu, choose Preferences, then choose File Handling:
Here, you’ll find the Automatically Save Recovery Information Every option, which by default is set to 10 minutes, meaning that Photoshop will save a backup copy of your work every 10 minutes. You can increase it to every 5 minutes, as I’ve done here, or if you’re more of a gambler, you can set it to save a backup copy once every hour (there’s also a 15 minutes and 30 minutes option):
It’s important to note that Photoshop isn’t saving over your original file (which would be very bad). The recovery information is kept in a separate backup file. If Photoshop does happen to crash while you’re working, simply re-open Photoshop and it will automatically open the most recently saved backup copy, complete with all the work you had done up to the point where Photoshop saved the backup copy (assuming, of course, that you had been working long enough for Photoshop to have made at least one backup copy). You’ll know it’s the backup copy because Photoshop adds Recovered to the file name (which is displayed in the tab at the top of the document window):

In this Photo Effects tutorial, we’ll learn how to add folds and creases to an image to make it look as if it’s been folded and unfolded like a map! We’ll use guides and selections to create the folded sections of the image, along with some gradients, a layer blend mode, and one of Photoshop’s filters to add highlights and shadows. We’ll even use a custom brush to give the fold lines a worn out appearance. This version of the tutorial has been fully updated for Photoshop CS6 (the version I’ll be using here) and is also fully compatible with Photoshop CC (Creative Cloud). If you’re using Photoshop CS5 or earlier, you’ll want to check out the original Folds And Creases Effect In Photoshop tutorial.How To Create A Folds And Creases Effect Step 1: Add A New Blank Layer
Since our new layer is blank, it won’t look like anything has happened in the document. But if we look in the Layers panel, we see that Photoshop has added a new blank layer named “Layer 1” above the original image on the Background layer:
The Layers panel showing the newly added layer.Step 2: Turn On The Rulers
Next, we’ll drag out some horizontal and vertical guides to help us out. Before we can do that, though, we first need to have Photoshop’s rulers turned on. Go up to the View menu in the Menu Bar along the top of the screen and choose Rulers. You can also turn the rulers on by pressing Ctrl+R (Win) / Command+R (Mac) on your keyboard:
The rulers will appear along the top and left of the document:
The rulers are displayed above and to the left of the image.Step 3: Drag Out Two Vertical Guides Step 4: Select The Rectangular Marquee Tool
Select the Rectangular Marquee Tool from the Tools panel, or press the letter M on your keyboard to quickly grab it with the shortcut:
Selecting the Rectangular Marquee Tool.Step 5: Drag A Selection Outline Around The First Section
With the Rectangular Marquee Tool selected, drag out a selection outline around the first section (the one in the top left of the image). The selection will snap to the guides:
Draw a rectangular selection around the first section in the top left corner of the image.Step 6: Select The Gradient Tool
Select the Gradient Tool from the Tools panel, or press the letter G on your keyboard to select it with the shortcut (the keyboard shortcuts for the Rectangular Marquee Tool and the Gradient Tool will come in handy in a moment):
Selecting the Gradient Tool.Step 7: Select The Black, White Gradient Step 8: Draw A Black To White Gradient Across The Selection
Drawing a black to white gradient inside the selection.Step 9: Draw A Selection Outline Around The Next Section
Switch back to the Rectangular Marquee Tool by pressing the letter M on your keyboard, then drag out a selection around the next section (the one in the top center):
Dragging out a selection outline around the top middle section.Step 10: Draw A Black To White Gradient Across The Selection In A Different Direction
Drawing the second gradient at a different angle than the first one.Step 11: Repeat Steps 9 And 10 For The Remaining Sections
We need to do the same thing for all six of the sections, but it’s just a matter of repeating the same couple of steps for each one. First, press the letter M on your keyboard to switch to the Rectangular Marquee Tool and drag out a selection outline around the section, then press the letter G on your keyboard to switch to the Gradient Tool and draw a black to white gradient inside the selection, drawing each gradient at a different angle to add variety. When you’re done, you should have a gradient across each section. Press Ctrl+D (Win) / Command+D (Mac) on your keyboard after you’ve drawn the final gradient to remove the selection outline around it:
Each section should have its own black to white gradient.Step 12: Hide The Rulers And Guides
We don’t need the rulers or guides anymore, so to hide the rulers, either go back up to the View menu at the top of the screen and reselect Rulers, or press Ctrl+R (Win) / Command+R (Mac) on your keyboard. To hide the guides, go up to the View menu, choose Show, then choose Guides, or press Ctrl+; (Win) / Command+; (Mac) to turn them off from the keyboard:Step 13: Change The Blend Mode To Soft Light
Go up to the Blend Mode option in the top left corner of the Layers panel and change the blend mode of the gradients layer from Normal (the default setting) to Soft Light:
Change the blend mode of Layer 1 to Soft Light.
This turns our gradients into a series of highlights and shadows in the image, and we can start to see our “folds and creases” effect taking shape:
The image after changing the blend mode to Soft Light.Step 14: Apply The Plastic Wrap Filter
To bring out the fold lines a bit more, we’ll use Photoshop’s Plastic Wrap filter. Go up to the Filter menu at the top of the screen and choose Filter Gallery:
Twirl open the Artistic category and choose Plastic Wrap.
The options for the Plastic Wrap filter are found at the top of the column on the right. Set the Highlight Strength to 20 and Smoothness to 15 by dragging both sliders all the way to the right. Then set the Detail option to somewhere between 5 and 10. The higher you set the Detail value, the tighter the effect will appear around the fold lines, so keep an eye on the large preview window on the left as you drag the slider and choose the value you think works best. I’m going to set my Detail value to 10:

Adding a second new layer.Step 16: Select The Brush Tool
To enhance the effect even further, let’s add some wear and tear lines to the folds, and we’ll do that using a custom brush. Select Photoshop’s Brush Tool from the Tools panel, or press the letter B to select it with the keyboard shortcut:
Selecting the Brush Tool.Step 17: Choose A Spatter Brush From The Brush Picker Step 18: Open The Brushes Panel And Select The Brush Tip Shape Options
Setting Roundness to 10% and Spacing to 50% in the Brush Tip Shape section.Step 19: Select The Shape Dynamics Options
Increase the Size Jitter value to 100% by dragging the slider all the way to the right, then set the Control option direcly under the Angle Jitter slider to Direction. Don’t close out of the panel just yet because we still have one more category to select:
Setting Size Jitter to 100% and Angle Control to Direction in the Shape Dynamics options.Step 20: Select The Dual Brush Options
Choosing the Spatter 27 pixels brush, setting the Blend Mode to Multiply, Size to 55 px and Spacing to 55%.Step 21: Set Your Foreground Color To White
We need our brush color to be white, and Photoshop uses the current Foreground color as the brush color, which means we need to make sure our Foreground color is set to white before we start painting. The easiest way to do that is to first press the letter D on your keyboard, which will reset the Foreground and Background colors to their defaults (making the Foreground color black and the Background color white). Then press the letter X on your keyboard to swap the colors, which makes the Foreground color white. You can see the current Foreground and Background colors in the color swatches near the bottom of the Tools panel:
The Foreground color (upper left) swatch should be white.Step 22: Paint Across The Fold Lines

The image after adding the brush strokes.Step 23: Lower The Layer Opacity (Optional)
Finally, if the brush strokes look a little too white and intense, you can fade them more into the image by lowering the layer’s opacity. You’ll find the Opacity option directly across from the Blend Mode option at the top of the layer’s panel. By default, opacity is set to 100%. I’m going to reduce mine to 65%:
Lowering the top layer’s opacity.
And with that, we’re done! Here is my final “folds and creases” effect:
The final result.
Apart from being a great image editing program, Photoshop can also function as a PDF Editor. From importing, editing, and saving PDF documents, Photoshop has enough basic capabilities to do it all. Although it won’t be as complete with features like Adobe Acrobat DC has, it still is a totally valid option for creating PDF presentations. Here’s how to quickly save a PDF in Photoshop.
Now this covers the tip of the iceberg for working with and editing PDF pages. So let’s dive into the complete process of importing, editing, and exporting PDF files in Photoshop more in-depth.Video Tutorial How To Import A PDF In Photoshop
So as you can see, importing a PDF in Photoshop is just like importing any other image. The only difference is the import PDF dialogue box which provides some further import settings.
Here comes the important part. You’ll see a dialogue box with some controls. You’ll have options for Cropping, Bit Depth, Resolution, Size, etc…
Apart from that, you will have two options in the “Select” panel called Pages and Images. Selecting “Pages” will make Photoshop select individual pages for editing. If you select ‘Images’, then Photoshop will extract separate images from the pages for editing.
Although most of these settings are self-explanatory or can be left untouched, let’s quickly highlight the “Crop To” option as this setting will vary depending on your files.
Media Box: The media box defines the final page dimensions. It is the largest of all boxes.
Crop Box: Specifies the region that a PDF viewer prints
Trim Box: It is the final size of your page after printing and corrections
Bleed Box: Bleed Box is like a Trim box with some more space given. It is bigger than Trim Box
Art Box: It defines the content of your page along with some extra margin. It is the smallest of all boxes.
Most of these are used for commercial printing purposes. Select one which you like, but if you aren’t sure, the Media Box setting will get the job done.
Now Photoshop shall open all your pages in individual tabs (aka projects).How To Edit A PDF In Photoshop
Once you have all the pages opened, select one of the tabs for editing.
One important thing to note is that you can add extra things like annotations to your PDF but you cannot edit the existing elements like text or images as they are a part of the PDF itself and not editable.
If you wanted to remove something from your PDF, you would need to cover it up using the clone stamp tool or hide it behind a white shape layer for example. From there you could add new elements such as text to replace the covered area.
Apart from that, you can do pretty much everything else like adding shapes, annotations, text, adjustment layers, and more to stylize your PDF pages.
If you want more PDF editing options, then Adobe Acrobat is what you might want to consider.How To Save A PDF In Photoshop
Once you have edited to your heart’s content, it’s time to save your PDF. This part isn’t as easy as saving a regular image in Photoshop, but it’s very straightforward with the right steps. Here’s what you need to do:
Now you’ll be greeted by a dialogue box where you can configure some export settings.
If you were editing a multi-page PDF, then you need to select all your pages to be exported. With all the pages you want to include in the export already opened in Photoshop, select the checkbox which says “Add Open Files”.Step 3: Organize PDF Pages In Desired Order
The topmost file in your list will be the first page and the bottom-most will be the last.Step 4: Confirm The PDF Page Settings
Once page reordering is done, you can edit some other options too. Here’s what each of them means:
Save As: Select Multi-Page document to make sure that your PDF gets exported with all the pages you want.
Background and Font Size: Select a PDF background color. White is the best and for font size, 12 is what I would recommend.
Include: You can select the various elements you want to include at the bottom of your PDF. It can be Author, Copyright, Notes, EXIF Info, etc…Step 5: Finalize The PDF Export Settings
Here’s what options are available in this dialogue box:
Adobe Acrobat Preset: Specifies some preset Adobe Acrobat export settings. Choose ‘High Quality (Modified)’ here
Standard: Select the PDF standard to be compatible with. ‘None’ is best.
Compatibility: Select the version of the PDF you want to export. Choose something in the middle so that your PDF remains compatible with older services too.
Last, you will have a description box if you wish to have an embedded description with your PDF export.
As for the other options, they can be left as default.
In the sidebar, you will have other options where you can compress your PDF for a smaller file size. You can also configure some output color settings in the ‘Output’ tab.
In the ‘Security’ tab, you can set a password for opening the file and a password for even limiting actions like printing a PDF. This is a great way to protect your PDF presentation from being wrongly used without permission.
Finally, the ‘Summary’ page contains, a summary of your whole page if you wish to view the settings.
That’s it! Now check your File Explorer/Finder and you’ll see the PDF file saved to your computer directly from Photoshop. How easy is that?

If you want to get a good deal on a new phone, you have to time your purchase correctly. Buying it the day it officially goes on sale may feel good because you’re one of the first to have it, but it’s usually a big mistake. To maximize savings when buying a new handset, you have to be smart and patient.
I’m a frugal person and hate paying full price on anything, especially smartphones. To combat this, I’ve been paying close attention to phone prices over the years and have figured out the best times to buy a new one. Some tips may be obvious, but some might surprise you.
Here are the best times to buy a new phone!
The best times to buy a new phone
Up to a month or so before the new model comes out
Ryan Haines / Android Authority
This tip only applies to those who are happy to get a soon-to-be-last-gen phone model. The best time to buy a new phone’s predecessor is around a month or so before the latest model comes out, as that’s usually when retailers start offering discounts to get rid of their stock. Discounts are also available, sometimes even higher, right after the new phone hits the market. Wait too long, however, and retailers may sell through their stock.
For example, the Pixel 3, which launched with an $800 price tag in 2023, was available for just $400 the following fall, just a week or so before Google announced the Pixel 4 series. While this is an old example, the story is similar with a lot of new devices.
Research is key to a good purchase!
Keep in mind that to get the best deals, you’ll have to shop around. Check out as many online stores as possible to see which ones offer the largest discount. For example, the Galaxy S22 Ultra is listed at $1,200 on Samsung’s website at the time of writing, while Amazon is selling it for $994 — that’s over $200 cheaper. This just goes to show that research is key to a good purchase!
Pixel 7 — $499 ($100 off)
Samsung Galaxy S22 series — Up to $400 off
OnePlus 10 Pro — $549 ($250 off)
Remember that many retailers start offering deals a few weeks before Black Friday actually kicks off, so make sure to start doing your research then. And don’t forget about Cyber Monday deals as well, which are available on the first Monday after Black Friday.
During Boxing Day sales and beyond
Robert Triggs / Android Authority
Boxing Day falls on the day after Christmas Day (December 26). It offers significant discounts on phones and other products in places like the UK, Ireland, Australia, New Zealand, and a few others. However, it’s becoming an excuse for retailers in countries that typically don’t celebrate Boxing Day to grab consumers’ attention and increase sales with various deals. So no matter which country you live in, it’s worth checking out phone deals on this day.
While many people are familiar with Boxing Day, even in countries that don’t celebrate it, not many people know that there are deals to be had in the entire week after Christmas. These deals frequently extend into January as well. People generally spend less money during this time compared to the weeks leading up to Christmas, so retailers start offering discounts to get you to pull out your wallet. I got a lot of great deals a few days after Christmas over the last few years on various electronics and have seen many others on mid-range as well as high-end phones.Best time to buy Google Pixel phones
Never buy a Pixel phone at full price, as you can get a big discount or free gift if you buy one in the first month or so of its launch. For example, Best Buy offered a free $100 gift card with the Google Pixel 7 series right from launch.Best time to buy Samsung Galaxy S phones
Samsung generally releases its latest Galaxy S phone in February, and the trade-in deals are your best chance to save. The Galaxy S22 phones all received a discount of hundreds of dollars provided you were willing to part with your previous device. You can also wait until summer when there are substantial discounts without the trade-in requirement. At the time of writing, the S23 range is about to launch, and you can get $50 in Samsung Credit just by reserving one. It’ll also be worth watching for the pre-order deals when it gets announced.Best time to buy OnePlus phones
The best time to buy a OnePlus phone is during Black Friday or December. The company offered a $250 discount on the OnePlus 10 Pro during last year’s Black Friday in the US. There were similar deals available in other countries.
If you happen to miss OnePlus’ Black Friday deals, you still have a chance to save by getting a device from the company during December. For example, OnePlus celebrated its eighth birthday in January 2023 with plenty of discounts. However, keep in mind that OnePlus may not have the same level of celebration for every single anniversary.
OnePlus frequently offers discounts during Boxing Day as well — December 26. And in addition to Black Friday and December, OnePlus sometimes also provides discounts in August as part of their Back to School sale. There are also OnePlus Wednesdays on a weekly basis, but these tend to offer more modest discounts.Best time to buy Moto G phones
Moto G phones usually start getting their first discounts — up to $50 — around two or three months after they go on sale. But to get the best deal possible on any Moto G phone (or Motorola phones in general), waiting for Black Friday is the way to go. However, depending on which model you get, the phone could be as much as eight months old by then.Best time to buy iPhones
Apple typically announces its latest iPhone generation each September. The tech giant isn’t the most generous with discounts, but you can find a few great deals offered by retailers and carriers during Black Friday, which takes place around two months after the phones are released.
Your best bet is to try your mobile carrier. AT&T, for example, offers up to $1,000 off to consumers who bought an iPhone 14 series device with a qualifying trade.
There are plenty of iPhone deals available each Black Friday, but they differ from year to year. You’ll have to do a bit of research on your own to find the one that suits you best.
Can broccoli save us from osteoarthritis? BU researchers study influence of vitamin K
Tuhina Neogi, an instructor of medicine, and David Felson, a professor of medicine and epidemiology, won a grant from the Arthritis Foundation.
Researchers at the School of Medicine have some reason to believe that more trips to the produce aisle could mean fewer trips to the medicine cabinet for millions suffering from osteoarthritis, the most common form of arthritis. Now, with help from a $200,000 grant from the Arthritis Foundation, Tuhina Neogi, an instructor of medicine, and David Felson, a professor of medicine and epidemiology, hope to find out for sure. The two scientists are investigating whether vitamin K, found in green leafy vegetables and broccoli, can slow or help prevent the disease.
Osteoarthritis, which affects nearly 21 million Americans, occurs when the cartilage that cushions bone joints deteriorates from years of wear, leading to pain, stiffness, inflammation, and swelling. The disease most often affects the hands, knees, and hips, and is a leading cause of disability for seniors.
There is no cure for osteoarthritis. Current treatments focus on alleviating the pain and other symptoms. Finding ways of slowing or preventing the disease is a major focus of research within the University’s Arthritis Center, where scientists are also studying other rheumatic diseases, such as rheumatoid arthritis, the vascular disease scleroderma, and carpal tunnel syndrome. To support such efforts, the Arthritis Foundation has given Boston University nearly $3 million in research grants over the past seven years.
“The arthritis research that’s going on at Boston University is some of the most exciting prevention research we have,” says McCoy.
Neogi and Felson hypothesize that vitamin K, which is known to help proteins that work to clot blood, might also be important for proteins that build and strengthen bone and cartilage. “[Vitamin K] may make cartilage hardier so that it better withstands wear and tear,” says Felson. “It may allow the bone to respond in a more healthy fashion to the wearing away of cartilage. And it may act as an anti-inflammatory, reducing the inflammation of joint linings that causes pain.”
Neogi and Felson were encouraged by the results of an earlier, observational study they conducted, using X-rays and vitamin K assessments from a group of participants in the Framingham Heart Study, the ongoing National Institutes of Health epidemiological study begun in 1948 and overseen by BU since 1971. Participants with the highest levels of vitamin K in their blood exhibited 30 to 40 percent less osteoarthritis than participants in the lowest quartile of vitamin K levels.
Half the study participants received multivitamins with a large dose of vitamin K, while the other half took multivitamins that lacked vitamin K. The Arthritis Foundation grant will enable Neogi and Felson to obtain X-rays and to distribute joint-symptom questionnaires to participants during their final study visits, which will conclude by this October. Preliminary results could be available by the middle of 2007.
If a link between vitamin K and osteoarthritis is found, millions of Americans would have an easy way to help maintain their mobility into old age — eating more green leafy vegetables (which Americans typically don’t eat enough of) or taking a vitamin K supplement, “much like people now take calcium and vitamin D for osteoporosis,” says Neogi.
“Everyone wants to know if there’s something they can eat that can help with arthritis, and now we might be in the position of being able to say yes,” says Felson. “It’s a great opportunity, because it’s simple and it might have a tremendous public health and clinical impact.”
John Klippel, president and CEO of the Arthritis Foundation, agrees. “I think [the researchers at Boston University] have really been pioneers in approaching osteoarthritis from an epidemiological standpoint,” he says. “The fact that this disease is so common suggests that there could be common things that can influence it.”
