Cullergrader uses a perceptual hashing algorithm to group photos by visual similarity to sort through images rapidly. As a photographer with the habit of taking the same shot many times, selecting my best takes is often a time consuming process (especially with thousands of photos!). Unable to find a suitable tool, I built Cullergrader to solve this problem, saving me hours at a time going through photos. Cullergrader is now available on Github as an open-source project, which I plan to actively maintain and accept contributions for to improve it as a tool for the photography community.
