Shutter vs BackStep AI

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.

RECORD WHAT YOU TAKE APART. REBUILD IT STEP BY STEP. BackStep AI gives the physical world an Undo button. Record yourself taking something apart, mark the moments that matter, organize the parts, and turn your approved sequence into a clear reverse guide. HOW BACKSTEP WORKS • Create a project for whatever you are building, disconnecting, moving, or servicing. • Record the process and tap Mark Step whenever an important action happens. • Review and edit the captured steps before creating your guide. • Organize screws, cables, panels, brackets, and components in PartMap. • Follow your own process backward in focused Rebuild Mode. • Replay the original moment whenever you need more context. BUILT FOR REAL PROJECTS Use BackStep for electronics, computers, appliances, furniture, bicycles, camera setups, holiday displays, restaurant equipment, hobby equipment, and general household projects. BackStep is not limited to one device or one category. APPLE VISION PRO Continue compatible projects in a spatial workspace. Review the reverse sequence, inspect a volumetric PartMap, and follow one rebuild step at a time with your original evidence nearby. PRIVATE BY DESIGN No account is required. Projects and recordings remain on your device unless you choose to export or share them. Local processing is preferred where supported. AVAILABLE IN THREE LANGUAGES Use BackStep AI in English, Español, or Français from the in-app Settings screen. HONEST GUIDANCE BackStep organizes what you recorded. It does not replace manufacturer instructions or qualified service guidance, and it never invents safety-critical specifications. Free includes three user-created projects; the sample project does not count. BackStep Pro offers unlimited projects and additional premium workflows through optional auto-renewing subscriptions.
