About this tool

What Auto-Culler by Exposure does

A single blown exterior sky or muddy underexposed interior can tank an otherwise strong listing set. Agents notice; portals do not forgive. This auto-culler scores brightness with histogram and mean analysis so you can reject weak frames early — before watermarking, compressing, or uploading.

Process up to 30 files per batch. Each image receives a grade and brightness readout so you can sort keepers from rejects in seconds instead of scrubbing a Lightroom filmstrip. Pair with Blur / Sharpness Detector for focus QA, then convert RAW/HEIC and finish with MLS Ready.

This is classical image analysis, not generative AI — fast, predictable, and free. When you need full AI listing polish (perspective, color, twilight) across the keepers, hand the culled set to the FOCAL RAYS editor.

Workflow tip: run after bracket organize on HDR shoots, or after a mixed phone+camera dump. Cull exposure first, sharpness second, delivery third.

Night exteriors and true twilight frames can score “dark” by design — use grades as guidance, not an automatic reject for creative set pieces.

FAQ

Common questions

Is this AI culling?

It uses histogram and mean brightness analysis — deterministic and free. For full AI listing edits, use the FOCAL RAYS editor.

How many photos per batch?

Up to 30 files. Split larger shoots into rooms or cards.

What does the grade mean?

Grades reflect how blown or underexposed a frame is so you can reject extremes before delivery.

What should I run next?

Blur Detector for sharpness, then convert formats and run MLS Ready before portal upload.
