One of our favorite Photoshop tutorial websites, Phlearn, yesterday put out a tutorial that is both incredibly useful and a bit scary. Useful because making eyes pop in post is probably one of the most sought after Photoshop skills. Scary because this kind of manipulation is a slippery slope that could lead to photographers getting lazy and using the “fix it in post” excuse… so proceed with caution. Read more…

When it comes to sharpening an image, more than likely, your technique involves using a certain method over the entire image all at once. However, that’s rarely the best way to do it, because how much and where to sharpen varies quite a bit depending on what you’re shooting.
Fortunately for us, Photoshop wiz Michael Woloszynowicz is back again with another useful technique that will help you improve your sharpening skills and account for things like texture and edges. Read more…
Unsharp Mask: the sharpening filter of choice for photographers everywhere. It’s a fantastic tool that can really take an image to the next level when used correctly and I’m here to tell you that you should never use it again. That’s right, bid it a fond adieu and stop using Unsharp Mask. Forever.
In October of 2011, the tech world went into a frenzy after Adobe showed off some crazy image deblurring research it’s working on. By calculating the camera movements that caused the blur in the first place, the algorithm is able to “reverse” the motion blur and sharpen the photo. If you’ve been impatiently waiting for the feature to show up in a new version of Photoshop, you might want to check out Blurity, a similar blur removal tool that’s already available. The software has been available to Windows users for a while now, but just recently launched for Mac OS X as well.
The Sharpen Tool in Photoshop has always been useful in that it allows you to quickly sharpen specific areas in a photograph, but a major problem was that it had the tendency to introduce nasty artifacts into the image. Alternative methods that avoid this issue (e.g. using a new sharpened layer) became popular, leaving the Sharpen Tool to gather dust on many users’ tool pallets.
Well, if you’ve recently upgraded to Photoshop CS5, you might want to take another look at the tool. They’ve quietly introduced a new feature (on by default) called “Protect Detail”, which allows for brush-based pressure-sensitive sharpening without the annoying artifact problem.
Unshake is a free program available for all operating systems that takes your blurry photographs and attempts to make them clearer. While it’s not miraculous or perfect, it does in fact help in making photographs more usable, especially at lower resolutions (i.e. for the web).
Here’s a before-and-after example using a quick snapshot I took this past weekend with an outdated point-and-shoot camera:
If you have problems using the program on a Mac, try opening the Unshake.jar file directly at the last step. Larger photographs might also take much longer to “unshake”, while lower-res (i.e. 500px wide) photos were completed very quickly.
We posted a while back on how to sharpen your photos like Flickr for smaller resolution images. The technique used “Unsharp Mask”, but today we’ll quickly describe how you can ensure sharpness using a simple setting.
When you reduce the size of an image in Photoshop, there’s an option on the Image Size screen that allows you to choose how the image is resampled (shown above). By default, this is set to “Bicubic”, but that’s not optimal for shrinking photographs down to smaller sizes for the web. Instead, you should use “Bicubic Sharper” to preserve the sharpness in your photo.
Here’s a demonstration of the difference. The following photograph was resized from 3883px wide down to 500px using “Bicubic”:
Now compare that photograph with the following version, which we resized using “Bicubic Sharper”:
You can hover your mouse over either photograph to compare it the other (you might have to wait a few seconds to see the change).
To set “bicubic sharper” as your default, go to
Preferences->General->Image Interpoation->Bicubic Sharper (best for reduction)
If you’ve been resizing images poorly in the past, you should now see a noticeable increase in sharpness! Yay!
