FAQ

Do you collect my data?
No. All calculations — including the shutter count EXIF reader — run entirely in your browser. Your photos and inputs never leave your device.
Do I need an account to use these tools?
No account, no email, no signup. Open any tool and start working immediately.
How accurate are the calculations?
Each tool implements the standard optical or photographic formula. Results are verified against published references and match professional desktop applications. The precision is limited only by your browser's floating-point engine.
Which camera brands does the Shutter Count tool support?
Currently Nikon, Sony, Fujifilm, and Pentax. Each brand stores shutter actuation data in a different EXIF field — the tool reads the correct one per brand. Canon cameras do not expose this value in standard EXIF.
Does everything work on mobile?
Yes. All tools are fully responsive. Touch-friendly inputs and readable layouts work on any screen size from phone to desktop.
I found an incorrect result, what should I do?
Please reach out through the contact page with the tool name, your inputs, and the expected vs. actual output. All formulas are validated against optical and photographic standards and errors are corrected promptly.
I need a tool but it doesn't exist yet. Can you build it?
We'd love to hear that! Feature requests and tool suggestions are welcome. Reach out through the contact page with your idea and we'll consider adding it.
