One of the biggest advantages of shooting in RAW is that the final version of the picture can look very different. In the examples below I did only use different color profiles for Canon Digital Picture Professional. It is not changing much on light and contrast – obviously you do that when you work with curves – it is more on changing colors and mood.
Have a look yourself. From left to right it is a picture in Velvia-style, natural and retro style.
I really enjoy playing with these styles from time to time. Strangely you can see another effect here: With some pictures some curves do not work. What do you think?
