How adjusting your HDSLRs dynamic range can be useful.

Posted May 5th, 2010 by SLRHQ
A lot of information has been floating around about adjusting your camera's dynamic range or shooting flat, and a lot of people seem very confused on how all this works. Here are some tips to help give you a better understanding of what it all means.
- Shooting flat or using picture styles like "Marvels Cine," "superflat01" or using a custom picture profile like shown here, are intended for only one purpose; to capture more color data into the highly compressed H.264 that your camera creates. This will not give you a better or more cinematic look off the bat, but will give you more of a range of information to work with. It allows you to color correct and bring the contrast back in a way in which you can control, while still attempting to preserve highlights. So instead of baking the image with heavy contrasted, sharp and saturated look, you're instead telling the camera that you want very little contrast and more details in the blacks and will adjust it later. However, canon's built in picture styles do look great out of camera if that's what you want and you don't want to fuss color correction.
You can see a sample of why this could be useful here.
On the left uses the "custom" picture profile setting. On the right is Canon's Standard setting.
Notice the shadows within the shrine on the right have been clipped to black and most of the color information has been lost. With the shadows on the left using the "custom" picture style, the color information has been preserved and can now be altered in post.
