In the process of selling my Nikon D90, I was asked by an interested party how many clicks there were on the camera. That’s another way of saying how much life is there left on your camera shutter. I do not know what happens when one reaches the point where they have 100% of the clicks, but manufacturers rate various cameras for shutter life. That might also be a good idea to know prior to buying a camera.

On my d90, I learned that I had 35,235 clicks on it, or had released the shutter that many times.. The process is simple. Just take a picture of anything. The site will prompt you to do a browse for that image, then ask you to upload it. Once uploaded it reads the image to produce the number of clicks it has on it.
