Someone asked me the other day how important Photoshop is to me and how often I use it. Here is a perfect example of how Photoshop helped me in this shot. Had I used a flash or a reflector, I might not have needed to do this post editing, but this was taken 3 years ago (or there abouts) and I wasn't as prepared as I should have been.
As you can see below, the photo at the top is WAAAAYYYYYY better than the original. I use either Lightroom or Photoshop on most photos - most often just for small tweaking - but in some cases like the one below, it can play a very big role in taking a photo from average to great.
After I am happy with my image - I give it a border and my signature logo, I resize it for screen viewing and -BOOM - hit the upload button!
