Shutter-Speed 2.0

Shutter-Speed allows users to accurately test the shutter speeds of their analog cameras using only their iPhone. To unlock the full potential of this application, it is essential to pair it with the PhotoPlug, an optical sensor that seamlessly connects to the headphone jack of your iPhone. This device enables precise measurement of the light passing through the camera shutter, ensuring accurate results.

How-To:

• Position your camera towards a well-lit area.
• Align the PhotoPlug closely behind the camera shutter.
• Initiate the measurement and trigger the shutter.
• The application will automatically interpret the signal and calculate the shutter speed.
• All measurements can be conveniently stored in a table within the app.
• Support for multiple cameras and lenses is available.
• The app computes a correction factor to address any inaccuracies in shutter speed measurements. For instance, if a measured speed of 1/60s is actually 1/50s, the app will indicate a discrepancy of 1/3 stops and provide a correction factor of -1. This signifies adjusting the aperture by 1/3 f-stop for correct exposure.

If utilizing Shutter-Speed without the PhotoPlug, the app detects and analyzes the sound of the camera's shutter to determine the speed. It's important to note that this method is suitable for speeds below 1/30sec. With the PhotoPlug, Shutter-Speed can accurately measure shutter speeds up to 1/500sec.
