I don't understand what DNG really is, but Adobe's technical documentation has these two statements. If a file can be opened in ACR 6.5, it would certainly open in 7.1. As neither of these two would change between images, I can't see why there would be any file size change.Īs for opening the files, Adobe has maintained forward compatibility for older cameras. The value of the specific pixel data could change, but a 16-bit integer value would be the same size, even if the data content of a specific data value changed. The files contain the headers for the metadata and then specific pixel data. I am surprised that you would have thought the files sizes would be different. In some cases, I suspect that the only changes were the data sets for the camera models, with the basic raw conversion engine not changing at all and a new version number would be assigned corresponding to the version of Photoshop. Camera Raw is not backwards compatible, so a camera that was released this year would only work with the ACR shipped with Photoshop CC 2015. The main difference between the other releases has more to do with additional camera models that were added to the compatibility list. Prior to that I would use either Nikon View NX2 or DxO Optics Pro for critical conversion work.

As an end user, I saw significant quality improvements in the output from the raw converter, especially with respect to skin tones on Nikon cameras. I believe that this was when CS6 was released. The Camera Raw engine was given a major overhaul in 2012. Unfortunately, I am not quite sure of the various versions and how they were released with the various Photoshop versions.
