I’m in the middle of evaluating different photo editors. I use Capture One Pro for almost all my photo editing work. It does a great job and in most cases I don’t need any other program. But Capture One Pro can’t do more advanced work like merging multiple exposures or frequency separation. Adobe’s Photoshop is of course a very popular choice for a lot of people. I’m not going back to Adobe since they introduced their “creative cloud” concept with a monthly fee though. If I pay money for software I want to own it. So Photoshop is out of the question for me. There are a number of other candidates to choose from.
When preparing your photo for printing it’s very important to have control of your colors. By that I mean you have to make precautions so that the colors you see on the screen represents as closely as possible the colors that will be printed on the paper.
I have spent some time figuring out which RAW converter suits me best. When I started shooting with more serious gear than point and shoot cameras I decided, without actually doing my normal investigation work, that Lightroom was the best choice for me.
