It all depends on who you are taking photos for. And what enjoyment you get from taking photographs. If it is about taking shots for magazine covers you will want all the help you can get from software. Some people enjoy the post processing as a part of photography. For me, I like to take pride in getting it done in the camera. I might remove backscatter to clean up, or crop or change colouring slightly, but the pictures I am most proud of were done in the moment of clicking the shutter.
This was taken in Dahab and gave me a real wow moment. I only had one strobe at the time and only had the DSLR for a few months. I took a couple of shots and was really disappointed with the colouring. I made a slight adjustment to the strobe positioning and edged slightly closer and suddenly all the beautiful reds came out. No need to Photoshop.
