FastPictureViewer is a high-performance image viewer for Windows designed for photographers and visual creatives who need to review large RAW image sets with speed and accuracy. It focuses on instant previewing and a minimal interface so you can rapidly cull, compare and pick selects without waiting for thumbnails to generate. It supports a wide range of RAW formats, including Canon CR2 and other manufacturer files, and offers accurate color rendering, instant zoom and pan, side-by-side compare, slideshow and lossless rotation. Advanced tagging, quick rating and metadata editing (EXIF, IPTC, XMP) let you organize large shoots on the fly, while fast caching, multi-threaded rendering and customizable keyboard shortcuts keep navigation fluid during long review sessions. Built for professional workflows, the viewer integrates smoothly with tethered capture and existing post-production pipelines to shorten the time from capture to selection. Batch tagging, export-friendly metadata handling and lightweight performance on Windows PCs help you move projects through post quickly and maintain an efficient image management routine.

I love the speed and simplicity of FastPictureViewer! It's such a joy to use while sorting through my images. The only drawback is that it sometimes lags with extremely large files. Still, totally worth it overall!
