ImageSnap

What ImageSnap is

ImageSnap is a free command-line tool for capturing still images from an iSight or another video source on macOS. It can list available video devices and select one by its full or partial name. Captures can be saved as JPEG, TIFF, PNG, GIF, or BMP. Timed capture is supported, with an option to limit the number of pictures in a timelapse. The historical page documents sending JPEG output to standard output by using a dash as the filename. The current project README describes version 0.3.0 as a Swift rewrite of the original Objective-C tool that uses AVFoundation. Capture has a default three-second camera warmup period, which can be adjusted. The software is released into the public domain and is attributed to Robert Harder. It requires macOS 13.0 Ventura or later and a connected built-in or external camera. On first use, macOS may ask for camera access permission. Building from source requires Xcode 15.0 or later, and the README also documents compiling with swiftc.

Who it suits

It suits macOS users who want to capture still images from a connected camera using command-line controls. Timelapse capture and device selection are available for users who need those options.
