Hello, I read that BMP format produces better quality but the file size is large. JPEG is the other way around. Although I am using a MBP 2010 now, I plan to upgrade the computer to the best available one next year. Is there a noticeable difference when the photos are printed, displayed on a 4K/5K display, displayed on a retina device (rMBP or iPad Pro of next year) and on a LCD monitor 3-5 years old? I did some simple tests. On my MBP 2010 17", under Preview, a photo saved in BMP format appears to be brighter and richer in colors. However, the file size difference is 24.9MB vs. 512KB. I wonder if photos in BMP format under retina display, 4K and 5K are much much better than the same photos in JEG format. Eventually, I need the files in eps format. Converting MBP to EPS and JPEG to EPS does not change the quality.
