Light Lamb is a free photographers’ light meter app for iOS. You can let Light Lamb decide everything for you like getting an auto mode for your manual film camera, or you could have full manual control of the parameters, or whatever you want in between. - Now with histogram (New in 1.3.0) Use the histogram to make sure the scene is exposed just like how you envisioned. - From full auto to assisted manual control In most cameras if you pick a parameter like aperture, shutter, or ISO, the camera would stick to your chosen values even if it's too dark or too bright for the scene. The reason we made Light Lamb is to have a light meter that would suggest different settings if the chosen parameters are not suitable. For example, you can keep your settings at f/8 and 1/125 for deep depth of field and fast shutter speed, but if it's too dark, Light Lamb would suggest brighter values to make sure it's correctly exposed. Or say you want to set the aperture to f/1.4 for shallow depth of field, and if it's bright outside and the shutter is already at its fastest speed, Light Lamb would suggest a smaller aperture. Just set the parameters to what you want and Light Lamb will handle the rest. - Safe shutter-aware Pick a preferred slowest shutter speed you want and Light Lamb will match it. If the scene is too dark, Light Lamb automatically pick a slower shutter speed beyond the safe shutter to achieve the correct exposure. - Spot metering Zoom in 5x to focus the measurements to small areas in contrasting scenes. - Match your equipment Choose the range and increment of ISO, aperture, and shutter speed to match your equipment. Choose between whole-stop, half-stop, and one-third EV increments for each parameter. - Keep a memo Keep a memo of the settings used, including a photo of the scene and the location. Export it as a beautiful picture note formatted in 4:5 aspect ratio, great for posting to Instagram along with your photo.

About

3D Cam SBS

Read full description

3D Cam SBS turns your iPhone into a stereoscopic (3D) camera. The app is only compatible with iPhones that have two diagonally arranged cameras (e.g. iPhone 13, 14, and 15 — non-Pro models only). Using both lenses, it captures side-by-side (SBS) 3D photos and videos. Because the cameras are diagonal, you simply rotate your iPhone by 45° when shooting. A built-in levelling guide helps you hold the device at the correct angle. Please shoot in bright lighting conditions — in low light, the ultra-wide lens may produce a blurred image in one eye, leading to poor 3D effect. We also recommend keeping the shooting distance within 5 metres, as the two lenses are very close together; otherwise, the 3D effect will be reduced. Note: This app only works on iPhones with dual cameras arranged diagonally. Other models are not supported. Due to diagonal capture, resolution is limited: video output is 2160×1080 (1080×1080 per eye), photo output is 3200x1600 (1600×1600 per eye).
