People, I am trying to work out why there is such a large file increase when I edit a file and save it. The background info:
Original file (from digital camera) - format, size, depth, geom: JPEG 680590 8 2048x1536 After opening and saving original file with defaults (85% quality): JPEG 646554 8 2048x1536 After opening and saving original file with defaults but with 100% quality: JPEG 1618121 8 2048x1536 After opening, cropping and saving original file as a PNG file with defaults (compression 9): PNG 4722953 8 2048x1536 After opening, cropping and saving original file with defaults but with 100% quality: JPEG 1631911 8 1590x1332 Questions: - When saving as JPG with 85% quality am I losing information? - How can saving as JPG with 100% quality increase information (file size)? - Why is PNG so inefficient? - imageinfo doesn't seem to be able to indicate information structure /compression information differences between the files - is there some way of doing this?
