Light Meter vs Video Speed Shift

Light Meter helps you measure exposure in real time and find the right camera settings faster. Designed for photographers and filmmakers, the app turns your iPhone into a practical exposure meter for everyday shoots, studio work, portraits, landscapes, and low-light scenes. Quickly read the light in front of you, lock the settings you want to keep fixed, and let the app calculate the missing exposure value automatically. Whether you are shooting with a digital camera, film camera, cinema camera, or manual lens, Light Meter helps you work with more confidence before you press the shutter. • Live Exposure Reading Measure light in real time and instantly calculate camera-ready exposure settings. • Lock Any Two Controls Choose which two settings stay fixed - ISO, shutter speed, or aperture - and let the meter calculate the third automatically. • Shutter Priority Freeze motion or create blur while the app calculates the right aperture. • Aperture Priority Set your depth of field and let the meter solve the matching shutter speed. • Auto ISO Keep shutter speed and aperture fixed while the meter adjusts ISO automatically. • Spot Metering Tap the preview to meter a specific part of the scene with more precision. • Built for Real Shoots Use it for portraits, landscapes, studio lighting, street photography, film photography, and video exposure planning. Light Meter gives you a fast, visual way to understand exposure before shooting. It is especially useful when working with manual cameras, adapting to changing light, checking mixed scenes, or planning a consistent exposure setup. Simple enough for beginners, precise enough for advanced photographers. Terms of Use: https://www.optionalchaining.com/terms-of-use Privacy Policy: https://www.optionalchaining.com/privacy-policy

Change how fast your videos play, then save the result to your photo library. Pick a video from your library or record one in the app, choose a speed, and watch the change right away. When it looks right, save it. The new video is written as its own file — your original is left exactly as it was. FOURTEEN SPEEDS 0.1x, 0.25x, 0.5x, 0.75x, 1x, 1.25x, 1.5x, 1.75x, 2x, 3x, 4x, 6x, 8x, 10x. The slider steps between them, so you can feel each one without looking. Take a golf swing down to a tenth of speed, or push a long clip through at ten times. SEE IT BEFORE YOU SAVE The preview plays at the speed you picked, so you are never guessing at the result. Play, pause, and scrub anywhere in the clip while you decide. AUDIO PITCH, YOUR CHOICE Changing speed normally drags the pitch along with it, and voices come out squeaky. Keep the pitch where it was, or let it ride with the speed for the classic effect. One tap either way. PORTRAIT AND LANDSCAPE Whatever orientation you shot in comes back the same way, at the resolution you started with. EVERYTHING STAYS ON YOUR DEVICE Your video never leaves it. There is no account to create, no upload, no ads, no analytics, and no crash reporting. The app asks for the camera and microphone only when you record, and for permission to add to your photo library only when you save. That permission is add-only, so the app cannot read what is already in your library. Picking an existing video goes through the system photo picker, which hands over just the one you chose. Free, with nothing to unlock.
