What is Shuttersnap? Shuttersnap is a free web tool that lets you check your camera's shutter count instantly
by picking a RAW file.
What is Shutter Count? All DSLRs and most of the mirrorless cameras have two moving curtains(Mechanical shutter) that actuate each time you take a photo. Manufacturers define an expected lifetime of actuations per model for these shutters(like 100,000, 200,000 or even more with some pro grade models) as they wear out with usage and end up failing. (Number of actuations of these two curtains are referred to as the shutter count.) Although it's replaceable, shutter count is a crucial factor when determining the expected
lifetime of your camera's shutter and when it comes to camera buying decisions.
Is this relevant for any camera? This is valid for all DSLR cameras and most of the mirrorless cameras except some of the
modern flagship mirrorless cameras like Sony A9 iii, Nikon Z8 and Nikon Z9 where there is
no mechanical shutter to wear. Instead, they use an electronic shutter mechanism which does
not wear out as you use it. But with many mirrorless cameras, there is an option to use an
electronic shutter in addition to the existing mechanical shutter which will not cause an
increase in aforementioned shutter count.
Raw Files
What file types can I pick? You can retrieve the shutter counts from the RAW files taken from supported cameras(refer the "Supported Devices" tab). Some common formats include .arw, .sr2, .srf and others.
How should I transfer raw images for accurate shutter data? Always use raw images directly from the camera without any manipulation or without going
through a saving pipeline from any third-party software. Make sure the image is completely unedited and in its original state, as saved by the camera. Open
your file manager, locate the latest image from the folder, and drag it into the tool.
What should I avoid?
Do not use special transfer software.
Do not open or edit the image in any photo editor.
Editing software often destroys embedded shutter count data.
Privacy & Security
Are my photos uploaded to a server? No. All processing happens locally in your browser. Your RAW files never leave your device.
Is any data being collected? The only information collected is the anonymous page view count incremented by the privacy
focused free and open source goat counter. Anything else including images are not stored
or sent anywhere. Once you close the tab, everything is gone. The only reason for collecting
page view counts is to understand the usage of the tool to determine whether to keep it running
or not.
Troubleshooting
My file isn't working. What should I do? Make sure your file is a supported RAW format and is from a supported camera model. Try another
raw file if it still fails.
