설명
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.
새로운 기능
버전 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.
평가 및 리뷰
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.
It does work
Bought a photo plug years back and I could never get the clean on and off signal as shown in their company video. The signal captured was full of noise. Until I realized that most of the iphone lighting adapters are for headphones . Until I got a "trrs (tip, ring, ring, sleeve) to lighting" adapter for microphone. Most are "trs" and will not work properly when connected to an iphone, Also ensure it's Apple MFI certified. Now it's working without issue.
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!
