Blend a recent aerial sweep with an older orthophoto so land-use change is visible but not distracting: align the new sweep to the older orthophoto, use a low-opacity overlay or soft blend mode to show differences, and save the composite with separate layers preserved.

Make change interpretation easier for planners by aligning both datasets to shared control points, apply a subtle color shift or tint to the recent sweep so changes read immediately, keep an adjustable layer mask for reviewers to toggle, and provide a change-highlight layer that flags major differences.

Questions people ask

honest answers

Because you rarely think 'I want the redaction tool'. You think 'I have to share this without leaking the client's details'. Start from the need, and the feature finds you.

Real. Every job here was drawn from what people in real roles were actually seen doing in Photoshop — not a feature checklist.

No. Each page gives you a ready prompt you can paste into an AI assistant, plus the plain steps to do it yourself. Start with either — the goal is the finished job, not the tool.
