Shutter Speed Tester for your smartphone - Check the shutter of your analog camera

Maybe you want to buy an old analog treasure and want to know if the shutter speeds are right before you buy it. Or maybe you want to check your existing camera. In this video, I'll show you a simple and inexpensive tool to do just that.
Step by step, I'll show you how to test your camera's shutter, whether it's a focal plane shutter or a leaf shutter.
Of course, this is not a 100% scientific test, but it will give you a good indication of the condition of your (future) camera's shutter.
And no, I don't get any money for this presentation and I bought and paid for this tool myself.
Thank you very much for your interest and your time.
