Every shape is real.

Sharp, in the browser

Sharp on the web

sharpmerge.com puts several shots of the same scene together into one, on any computer, with nothing to install: focus stacks sharp from front to back, bursts averaged clean, passers-by taken out, star trails kept, exposure brackets blended, panoramas stitched, and the sharpest shot of a burst picked — from photos, RAW files or a video's frames. Sharp Pro for the web, US$10 once, lifts the 12-frame limit, adds the retouch brush and 16-bit TIFFs, and has tools of its own: a long exposure from a burst, a motion sequence, a night sky over a sharp landscape, super-resolution, a time-slice from day into night, and cinemagraphs.

Shaders, a playground and a Mac app

Ray Kiln

A new Metal shader in every episode. A short video on its page builds it from nothing, beside the full source, every parameter explained, and the sound it makes, which the shader generates too.

The playground runs every episode in the browser to change and share, with exercises that ask you to rebuild each stage by eye; the gallery keeps what people make. The free Mac app turns a shader into a video, a still or a loop, and runs SwiftUI's shader effects ready for Xcode. Ray Kiln Plus, US$10 once, adds ProRes and transparent video, a live wallpaper and screen saver, sound and MIDI, keyframes, your own camera and pictures as inputs, and a performance mode for a screen on stage.
