Images intended for printing should be taken at the highest resolution setting for best print quality. Lower resolution photos printed at too large a print size may stretch the pixels beyond the point where they look sharp or clear. If your file was captured at a low resolution, artificially adding to the file size will not significantly improve the print quality. The chart below has been provided as a rule of thumb only and is based on the file’s native resolution from the camera and for properly exposed files. You can also view your files at 100% in PhotoShop for a good representation of how the file will print. To view your file size, open the image in PhotoShop to check the full image size and not the compressed JPG file size.
