Every now and again, you learn something new out of pure chance. This is certainly one of those cases! Till today, I've considered myself pretty good at editing my images but after finding a new tool in Photoshop, I've realised that I've been doing things the hard way!. Just out of curiosity today I tried a feature called 'Unsharp Mask' and what a difference it made to my images! When used correctly, it can extract the right type of detail in your image by adding more contrast to individual pixels via a ratio you provide. Basically, it gives the impression of sharpness without actually sharpening the image too much. I've added an example below: On the left is the un-edited foggy image and on the right I've applied only a heavy Unsharp Mask. The image isn't actually any sharper than the one on the left, it's just deepened the blacks and tightened the whites giving you the impression of overall contrast which makes the image much more pleasant to the eye.
As you can see, it really made a huge difference to this photograph which I considered not using at all because it was so foggy at the time. Safe to say, fog won't be keeping me indoors anymore!
