"Digital Negative (DNG) is a patented, open lossless raw image format written by Adobe used for digital photography."
EDIT: Also, when lossless is used to describe compression, it means that the original data can be rebuilt with bit for bit accuracy. Compression that can't do that is called "lossy". Things like ZIP, GZIP, and BZIP are lossless, but they are also not optimized for images, and are commonly used for miscellaneous computer files.
GAH! You are absolutely correct. A bonehead post on my part. I need to pay more attention to things. DNG vs PNG... DOH!!

Originally posted by Fcsnt54 I was speaking of .dng not .png. There is a difference and i agree with you 100%. I havent had any issues using the other raw file the camera shoots in and it seems more compatible with many softwares in comparison to the .pef raw file the camera shoots in.
As I said, I sloppily replied without catching my mistake... You are correct!!
HOWEVER, having said that, if given the choice, why would I choose to have my raw image "rebuilt"? The whole point of raw is to capture the most digital image information possible, bringing to bear the least amount of manipulation to render that data into the scene we want. The analogy; why would I cook lasagna, take it apart by separating the layers, and then put it back together just before serving? It's a needless process to change my raw image into a format that just is not catching on. Given Adobe's past, I can see a day when they would think nothing of suddenly, without warning, stop supporting the format, or deciding that all DNG files can only be adjusted with Adobe product. I don't trust Adobe any further than I can throw the company out the window.
