RAW file size in d200 vs d70 - DPChallenge Forums

01/15/2007 02:32:54 PM · #1

I read in d200 specs that its RAW file size is 15MB. Can anybody explain me why it is so large compared to d70 where it is only ~5-6MB? The pixel count differs by less than a factor of 2... Is it more bits or less compression, or both?
Thx! - Lev

15mb is the uncompressed RAW on the D200.

The D70 uses compression.

edit: compressed D200 Raws are 8-10mb typically.

yea, on the D200 you can turn RAW compression on or off.

To make things more confusing the remaining number of images counter on the D200 acts like you are always shooting uncompressed RAW files (when shooting RAW).

So your counter may say you have 200 shots left when in reality you have 300 left. So the picture count is more of a "on the safe side, only figure you have this many shots left"

FWIW, it makes little sense to turn the compression off since the compression is lossless.

Nikon likely only included the ability to turn it of to calm the complaints from perfectionists that trust nothing.

With the D200 you can even change the compression for jpegs as well.
