Of course RAW exists as an image format, complete with specification! Just that it tends to be unique to each camera and the full spec usually isn't publicly available!

So why have I noticed it after only a few saves (I was editing/saving an existing file - I've never shot a JPG on a camera that supports RAW)? JPGs *will* lose info on each save!
The argument over whether to shoot RAW or JPG and edit lossless or lossy will go on forever but lossy will lose info and lossless won't! Message ends!
