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
Works Pretty Good
The app works pretty good, especially for measuring the slower speeds. You do have to kinda identify the click of the shutter curtain releasing from the click of the mirror (and also the click of it closing) which makes it challenging to use at shutter speeds 1/250 or faster. Otherwise, it works as advertised!
*you can buy the photodiode accessory on their site for more accurate measurements. I found the waveform based sound measurement acceptable for my purposes so I didn’t.
