A high-resolution image requires a large amount of space on your computer's hard drive to store the image detail. Balancing file size against available storage space is the biggest balancing act involved in digital imaging. How high a resolution should you use when taking pictures to ensure a high-quality picture? The short answer is that you have to plan ahead. Unlike in traditional photography, you have to take into account how you want to use the pictures before you shoot, and then set your camera to capture either higher or lower resolution. Read our article on getting the best out of your digital camera.
There are numerous file formats, each identified by a file name extension, such as .bmp, .tif, .jpg, .jif, .gif, and .psd. Each file format saves the image using a different method. One of the most useful formats is JPEG (short for Joint Photographic Experts Group), which uses a .jpg file extension. JPEG compresses files to create a smaller size file. However, the JPEG file format is called "lossy" because it loses some of the quality (or some of the pixels) from the image. Depending on the level of compression you choose, JPEG can create a relatively small file with higher loss of quality, or a larger file with little noticeable loss of quality. See how many images you can fit on your memory card at different quality settings.
At Frogprints we recommend that if you have a 2 megapixel camera or better, that you set it to capture the largest image you can, with the highest level of compression (Basic). If you have a camera with less than 2 megapixels, we recommend that you use the lowest compression (highest quality) setting. This will ensure you optimise the number of images you can store on your camera, without compromising the print quality.
