This is a camera app that corrects distortion and perspective of photos. Whole photo, Documents, posters, arts such as paintings and calligraphy, exhibits, screens, blackboards, whiteboards, signs, screens, timetables, etc. You may want to leave a photo as a memo by taking photos with your smartphone camera or tablet camera. The problem is that the image of the picture is distorted by the influence of the camera lens. Even if the subject is at a right angle, it will not be a right angle photo. If the subject is rectangular, it will be a quadrangle with perspective. You can convert such perspective distorted quadrangle to the original subject rectangle. Cut out a free-form quadrangle from the photo and convert it to a rectangle. The cropping quadrangle does not have to be a right angle, and it is OK to use a trapezoid, a rhombus, a parallelogram, or a freeform quadrangle. If you can not shoot the subject directly in front of you, the photos will have perspective. To be precise, even if taken straight ahead, some distortion is inevitable. However, with this app, even photos taken from an oblique direction can be converted to rectangular images viewed from the front. You can edit the position of the corner mark for clipping while checking the clipping image on the preview screen in real time.

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).
