I have to comment on this usecase. Tiff is in my opinion the only way to save a lossless image with exif data. Exif data is important to keep in the workflow when using multiple image programs. You can say whatever you want about tiff but it is as ancient as jpg and this issue is important to solve. Looks like the libtiff library need an update?
