About this tool
What Before / After Slider does
Listing edits only sell when the improvement is obvious. Load an original and an edited frame, drag the handle to compare, and optionally export a still for email, Instagram, or a client report. Matching aspect ratios look best; different sizes are scaled into the comparison frame.
Use cases: photographer proofing an AI pass from FOCAL RAYS, agents reviewing twilight vs daytime, and QA after perspective or HDR merge. Export a comparison JPEG when you need a static artifact instead of an interactive slider.
This is an inspect/QA tool, not an editor. For the actual preservation-first edit (perspective, exposure, HDR, twilight), open the FOCAL RAYS editor. After comparing, deliver clean files via MLS Ready packs.
Tip: keep labels clear (Before / After) so non-photographer clients understand the story without a phone call.
Keep file sizes reasonable when emailing comparison stills — compress if needed — and never watermark MLS masters the same way you watermark private proofs.
