Honest comparison standards
Before-and-after photographs should show the same place honestly.
Matching angles, similar light, accurate captions and visible limits make a result record useful.

Same angle
Keep the crop and camera position consistent.
A matching viewpoint lets you compare the surface instead of comparing two different photographs.

Honest light
Do not use color edits to exaggerate cleanliness.
Wet surfaces, shade and time of day can change appearance, so captions should explain when each photograph was made.

Useful caption
Name the surface, scope and visible caveat.
A clear record says what was cleaned and what stain, wear or damage remained.

Static fallback
Both labels remain available without a slider.
Comparison controls can help, but the original labeled images and captions should never depend on animation.

Let’s figure out what the surface needs.
Send a few useful photos and we’ll review the surface, size, access and water details before offering a date.
