Todd has a Canon 5D Mk. III and he has been shooting JPG. He's starting to shoot RAW now and needs a program to edit them. Leo says the 5D Mk. III allows him to shoot RAW + JPG. That's pretty good because it gives him the option of either. RAW gives him a lot of latitude for color correction and post processing and Adobe Lightroom works great for converting it. It also has a simple workflow. The Adobe Creative Cloud Photographer Edition includes both Lightroom and Photoshop for $10 a month.
