Unshake

What is Unshake?

Unshake is an automatic deconvolver, a tool designed to recover the original, unblurred appearance of a photograph. Unlike common image processing filters that enhance specific visual elements like edges, Unshake attempts to reconstruct the original scene by estimating how the image was blurred in the first place. This is a complex task, as it requires determining factors such as the camera's focus, shutter speed, and other technical parameters that contributed to the blurring. Unshake stands out as the only free, automatic deconvolver tailored for non-specialist users to address common photography issues like poor focus and mild camera shake in single images of people or scenery. While it can typically only double or triple the resolution of a blurred picture, Unshake remains the sole such tool available to the general public since its initial release in 2000 The latest version, Unshake 1.5, has been enhanced for improved user experience and results. It provides users with more control, allowing them to adjust the processing time and select specific image areas to focus the deconvolution on. Additionally, the updated software can now estimate the processing time before committing to the task, empowering users to make informed decisions about its use
