I think 5 mega pixel image are .... (1)Superfine JPEG (100% / Adobe quality 10) =1,500 kb (1.5 Mb) (2)Fine JPEG (90% / Adobe quality 7) = 600 kb (0.6 Mb) (3)Regular JPEG (80% / Adobe quality 6) = 350 kb (0.35 Mb) (4)JPEG2000 (uncompressed) = 4,000 kb (4.0 Mb) (5)TIF (uncompressed) = 9,200 kb (9.2 Mb) like RAW image (6)TIF (LZW compressed) = 4,500 kb (4.5 Mb) (7)CRW (Canon RAW format)=2,300 kb (2.3 Mb) and then Mega pixel = Width and Height 0.063 = 320,200 0.224 = 640,350 0.3 = 640,480 0.5 = 800,600 0.8 = 1024,768 1.3 = 1280,1024 (like 1 mega pixel) 1.9 = 1600,1200 2.3 = 1920,1200 thanks,
