Compressing Sony camera raw images for storage
Sony please compress your ARWs losslelsy I'm sure the ARW image sizes has been a headache for many Sony A7* camera owners. It has certainly been for me. Sony's compressed RAW format is lossy (seems it uses some sort of delta encoding) and I hate using it. Even if it's often not visibly different from an uncompressed ARW the knowledge that dynamic range is lost on some pixels due to compression made me turn on uncompressed ARW's and leave it at that. In fact, in some scenes the effects of the compression artefacts are visible (he said without bringing up any examples -- but I'm too lazy to dig them out right now).
