Whats the advantage of TIFF over JPEG?
First you need to understand JPEG. JPEG is a lossy compression method, which means that some image quality is sacrificed to make the image file smaller. The amount of this sacrifice can be varied, though there is no agreed upon scale. Your camera probably has different JPEG modes, which correspond to different trade offs between quality and size. TIFF is actually a family of compression methods. The standard is fairly complicated and not all programs handle all types of TIFF files. Most programs, however, can handle a simple TIFF format in which no compression of any kind is applied. This requires 8 bits of resolution for each of the red, green and blue channels, or 3 bytes per pixel. Thus, the total file size will be 3xHxV bytes, where H is the horizontal resolution and V is the vertical resolution of the image. The advantage of TIFF is that no sacrifices in image quality are made to reduce the space requirements of the image. How significant is this? It depends on a number of factors
