[QUOTE="BackdoorArts, post: 92911, member: 9240"] There are two options on the D7000, Compressed and Lossless Compressed. Lossless Compressed saves about 20-40% from uncompressed (depending on image content) and Compress saves 40-55%. In "Mastering the Nikon D7000" Darrell Young says this regarding Compressed RAW... [I]There is a small amount of data lost in the compression method. Most people won't be able to see the loss since it doesn't affect the image visually. I've never seen any loss in my images with the Compressed mode. However, I've read that some people notice slightly less detail. Nikon says the Compressed mode uses nonreversible compression, so after you've taken an image using this mode, any small amount of data loss is permanent.[/I] My opinion is that if you're going to shoot in RAW mode it's because you want all the information available to you for manipulation - so why in the world would you want to lose any of it just to save a few bytes? If you don't need the information you should shoot JPEG's in Fine mode and get your thousands of pictures on a 32GB card. But if you're shooting RAW don't skimp - if only for that one time you can see the loss and regret it like crazy. [/QUOTE]
