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.filmomat.eu for detailed information and for ordering the PhotoPlug.
How-To:
Point the camera towards a bright light source. Place the PhotoPlug closely behind the camera shutter. Start the measurement and release the shutter. The App automatically analyzes the signal and calculates the shutter speed. All measurement values can be stored into a handy table. Multiple different cameras/lenses can be stored. A correction factor is calculated, which you can use to compensate a faulty shutter speed. For example, if you measure the 1/60s and it turns out to be 1/50s, the App will tell you that the shutter-speed is 1/3 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.
Without PhotoPlug, the App will record the sound of the camera shutter and calculate the shutter speed from that. Please note that this procedure will only give useable results for speeds below 1/30sec. With the PhotoPlug, shutter speeds up to 1/500sec can be measured.
What’s New
Version 2.1
- Fixed overlapping layout with Old/New Shutterspeed-Button.
- Added additional decimal digit to measured time (e.g. 1/8.2 instead of 1/8) for more accuracy.
Ratings and Reviews
Better with leaf shutters than focal plain shutters
Quite useful, but all the extraneous noise from a focal plain shutter makes it difficult to identify the peaks for setting the measuring points [even using the light sensor which plugs into a jack—which does not exist on newer iPhones]. Also better at testing slower speeds. The absence of competing apps perhaps indicates the difficulties of creating a really simple and accurate shutter speed tester.
They Photoplug device does not work!
Tried two of these and both don’t work. Tried different phones, ones with and without adapter. Tried everything. The first one never worked and I thought the signal was the photodetector but was actually from the mic. I tried using it again recently when I realised this but it was way out the return period so put it down to bad luck and ordered another. The second one is just the same. There’s no signal! Useless. Just don’t bother, I purchased two of these with shipping from Germany to UK and it’s a waste of money. Seller says I can return second unit but have to pay return postage from UK to Germany! Joke!
Still works on iPhone XS iOS 15.5
Tried it out again June 2022 using a Lightning to 3.5mm adapter on the photo plug and it seems to work ok. Not quite so convenient as you need to support the sensor at the end of a floppy cable.
