Built for the full workflow

Session Resume
Close drkrm, unplug your SSD, come back tomorrow. Your session picks up exactly where you left off — same photo, same ratings, same position.
File Browser
Navigate your drives with a built-in directory tree. Image previews load as you browse. Quick-jump to external volumes. Search by folder name.
Star & Flag
Mark standout photos with a quick S keystroke. Starred photos appear with a dot indicator in the filmstrip. Works in both Photo Cull and Recipe Lab.
Cookbook
Save, name, and version your recipes. Import presets from your camera's custom slots. Browse your collection with version history and one-click restore.
Diverse Collage
Nine photos selected algorithmically for diversity — different focal lengths, times of day, exposures. Shuffle for a new set. Pick manually from the full library.
Focus Mode
Click any photo to go full-frame. Per-photo recipe parameters with EXIF baseline. Navigate with arrow keys. Filmstrip stays accessible at the bottom.
Why drkrm

Camera-rendered.
Not approximated.

Every other recipe tool shows you a software guess. drkrm sends your RAW file to your camera and gets back the real JPEG — the same one you'd get shooting in-camera. One second per render.
