About this app
Matte Viewer lets you quickly preview the mattes in photos taken with your iPhone, including the depth map and semantic maps. You can export them and use them in 3rd party software such as Photoshop, Touch Designer, in custom shaders, and so on. To have the most matte data available in your photos, use the Portrait mode in iPhone's Camera. - Elegant and information dense interface that quickly lets you preview all the different mattes. - Supports desktop class features on iPad + Mac: multiple windows, open through drag & drop, keyboard shortcuts, etc. - Respects your privacy: no 3rd party libraries or tracking. Uses the latest iOS APIs so you don't have to give access to your whole photo library. - Extremely small app size: only a few hundred kilobytes. Matte Viewer is part of PhotoTools by Héliographe: check out our website at https://heliographe.studio for more fantastic photography apps.
