Bargain Hunter, the last write-up I read said that a typical 35mm film picture represented approx. six (6) megapixels ... about 4 times that offered by the Kodak DC260. To test storage requirements, I selected a high-res image called "Paintbrush" which I have used previously to test the resolution of inkjet printers. This detailed and colorful, 24-bit image required 1,135KB to store as a .BMP file but shrank to just 134KB using JPEG compression. On a computer display at 1,024x768 you really have to look closely to see any compression loss. Please keep in mind that the limiting factor is more often the lens as opposed to film. A resolving power of 100 lines per millimeter (~2,500 pixels on the vertical axis for 35mm) is generally considered to be excellent resolution for a high-quality lens. Zoom lenses and edge resolutions almost never offer this level of clarity. Craig
