The DNG images also appear to be a bit noisier, although that may actually be some other problem.
Can the DNG be improperly saved in CHDK?
Can the image in the camera degrade between saving the JPG and then saving the DNG?
Does the camera have access to something that allows its JPG images to be better than the DNG images?
Or, are the programs I'm using to display and convert the DNG files (display from imagemagick, and ufraw) at fault here?
Could it be that the camera does a better job interpolating the RGB values from the CFA than my software does?
I've been saving the DNG images because I believed they would contain more detail than the JPG images, not less.
I'm going to principally be taking shots of text (in a DIY book scanner), so I was a bit worried that the JPG format would degrade the edges of the characters.
Many people believe they can create a better image by applying their own post-processing steps
Unrelated for it,seems like camera doing some kind of NR regardless of the length of exposure. I'm made two bias frames, and the image with NR turned off is a lot brighter probably due to more noise.
NR turned off where?
QuoteNR turned off where?Right sides with NR turned off, the histogram is compressed in Photoshop.
