Let us know some specifics of the place your're sending them to so we can read the requirements and help you interpret them better. You should work in TIF and only convert to JPG once before sending the file out at 100% (or 0% compression) for stock, and anything lower for display only, like 65% to 85% for web display, but of course, web display also expects resizing down to only 1,024x wide or less, of course making smaller storage files. It all depends on thier meaning of 6mb expanded file size on screen in 8-bit color, or 6mp camera is required as a minimum capture? Tell us more.Īnd JPG is a final output format never to be re-edited again (a crime and a sin to edit a JPG and resave as a JPG), especially by you. Maybe they mean 6mb after expansion on screen, and in Adobe Photoshop, it tells your the "expanded" file size regardless of the original JPG compression, and it's 3x the pixels dimension since it really has 3 pictures inside - one red, one green and one blue!ģ5mm scan at 1.5:1 aspect ratio then = 1744x1183 pixels = 6mbĭigital 4:3 aspect ratio = 1673x1255 = 6mb I think that you might be misunderstanding their requirement.Ī 6mb JPG means nothing since JPG file sizes depend on too many variables to be predictable, like mage content (complex or simple, sharp or unsharp), image size (pixel dimensions), and compression ratio - all could ve vastly different to make a srotage file size of 6mb.
