Whats the difference between pixels, dimensions and file sizes?
Digital images consist of a number of pixels. Each pixel has a colour that includes a brightness. Together the pixels make up an image. The Ax CCD has about 5Mpixels for the A1 (5,000,000 pixels) and 8Mpixels (8,000,000 pixels) for the A2 in the ratio of 4 pixels horizontally for every 3 pixels vertically. A photo taken with the A1 at full resolution (max pixel dimensions) results in an image that is 2560 pixels wide and 1920 pixels high. You can set the Ax to take photos at lower pixel dimensions if you want to. When you display a full size photo (eg 2560 x 1920) on your computer monitor, you can either view it at 100% size or some other size. When you view it at 100%, every pixel of your photo shows up as 1 pixel of space on your monitor. If your monitor display is set to say 1280 x 960 pixels and you view your 2560 x 1920 pixel photo at 100%, it is clear that only half the photo height and half the width can fit on your monitor at any one time. In reality , you will see even less as
