You can also export a 'snapshot' of your camera's current settings which you can later apply back to your camera quickly and easily. Import camera settings from digital photographs by extracting the settings (ISO, F Stop, Exposure Time, etc) that were used when the photograph was taken, and set up your camera in exactly the same way. This can give you a good starting point for taking similar shots, and help you get to grips with the overwhelming range of settings your digital SLR camera has to offer.
