Snapmatica

Snapmatica gives the player a camera with real exposure controls: aperture across the full stop range, shutter speed from 30 seconds to 1/4000, ISO from 25 to 25600 and focal lengths from 8 to 800 mm. Exposure modes M, Av, Tv and P meter the actual scene, and an AF mode with a subject-tracking option keeps a moving creature in focus. Depth of field is computed from the optics and the subject distance, and focus peaking can be shown in the viewfinder.

The optical pass models diffraction, distortion, lateral chromatic aberration, focus breathing and long-exposure motion blur, and each of these can be switched off through the quality-reducing effect toggle. Sensor formats from medium format to M4/3, white balance from 2500 K to 12000 K, ND filters and a dynamic range simulation complete the setup. Output is PNG or JPG with EXIF data, or a linear DNG raw file, and a built-in camera roll shows each picture taken.

Snapmatica requires Fabric API. It is client-side only, so a server does not need to install it and can run a modpack without touching the server. Files are published for Fabric, Forge and NeoForge, with builds listed 1.12.2 – 26.3, and the mod is released under the MIT License as open source. The interface supports English and Japanese.
