User Reviews for Shutter-Speed

Very usedful

For old large format lenses to measure their accuracy to be able to compensate if necessary.

And a Calibration table to boot!

This is an ingenious iPhone App. It does what it says and I've gotten credible readings for a Rollie Twin and a vintage Voigtlander. The interface is fine, but you need to add a camera first. Saving to no camera causes a soft exit from the program. I now have correction tables automatically generated for both cameras. I'll probably add the $16 light sensor for more accurate readings, but I am delighted with what I have. Best, Jim

Great app for shutter estimation on old cameras

This app made it very clear that the shutter was twice as long on all speeds under 1/100 sec. Easy to use. Accurate even at 1/50 using sound. I like the control of doing the analysis yourself instead of the app using some algorithm. I have not tried with the light adapter. That could very well extend the usefulness past 1/50.

Great idea, not quite operational

The idea is great and the measurement process (at least the only one I can use, 1s) work well. The problem is that, at least on my iphone 3GS the interface is not working correctly. The screen appears to be cut in half and I cannot change the target speed. Once it reads and you want to set the pick values by zooming in, it will not stay when you zoom out, and it is difficult to do it on small scale. Also it's a bit of a bummer that you cannot organize your camera in the list, after inputing them, or delete a reading (you have to replace it with a new one). Upgrade, my friend? I would like to keep on using it, as I have several old cameras.

Useful for testing analog cameras

A good idea for folks who work with older, analog cameras - the simple idea here is that you can listen to the shutter or, with a simple light sensor available from the author, examine the light coming through the shutter and determine the shutter speed. The app provides a database for you to store results by camera.There are room for improvements (the application doesn't try and do its own analysis of the data, it's up to you; the application makes assumptions about possible shutter speeds) but those of us who need this kind of application will probably find it useful nonetheless.

Great app, still needs improvements

Love the app, exactly what I needed. I really appreciate the update with the old speeds but it still lacks flexibility, if nothing else the addition of 1/75 would help me but what I would like to be able to do is select any possible shutter speed, so after I use the app to test the first time, I can now come back with my updated shutter speeds and test how much they've changed (which they do in those old compound shutters)

Works very well

This app is excellent - zooming in/out on the waveform works nicely and it is easy to position and save measurements to the many mechanical cameras I own. It seems quite accurate between 1/1 and 1/15 even just using the built-in microphone, and that's plenty for me to perform simple checks for slow shutter speed accuracy. I've been using it mainly with SLR's, with the film door open and holding the mic close to the shutter mechanism.Thanks!

Nothing works

Nothing works in this app. I’m using it in iOS 13.

Works fine!!

If you know anything about cameras this is simple and easy to use. A shame to trash a perfectly good piece of software because you’re clueless. The description makes it clear that it only works to 30th without sensor and instructions are built in.

Doesnt work

Got this to use with a 2018 ipad and got the photoplug as well. The audio only method works fine, but the software doesnt recognize the photoplug. Old software, i suspect the developer has lost interest.

Description

With Shutter-Speed you can test the Shutter speeds of your analog cameras just with your iPhone. Please note that the full potential of this App is only reached if you use it in combination with the PhotoPlug. The PhotoPlug is an optical sensor which connects to the headphone-jack of your iPhone and enables you to measure the actual amount of light passing through the camera shutter.

Please visit www.photoplug.de for detailed information and instruction. The App also allows you to save the measured values into a handy table. Furthermore, the App automatically calculates a correction factor, which allows you to compensate a faulty shutter speed. For example, if you measure the 1/60s and it turns out to be just 1/50s, the App will tell you that the shutter-speed is 1/3 f-stops too long. This gives rise to a correction factor of -1, indicating that you have to close your aperture by 1/3 f-stop to get a correct exposure.
