Although DPP is rendering RAW files very nicely, it has limited functionality and not ideal for handling large number of files. Its also extremely slow on MACs (due to a known problem managing folders with over roughly 400 images). I am seriously contemplating the possibility of switching to Lightroom 4.1. After first trials, it looks that RAW files are rendered in a different manner than DPP. I have tried changing some of the adjustment parameters, but I have not managed to make them look similar yet. Do you know of any reliable Canon presets I can use to make them looking similar?
