Rinse
Drag a finger across the sheet, left to right, to wash the unexposed coating away and bring up the blue.
Honest framing. Afterlight is a drawing instrument, not chemistry. Nothing is measured, graded, or predicted, and no light sensor is involved — exposure is simply how long you hold the button. Everything runs in this tab: no network requests, no storage, no accounts. Close the tab and the sheet is gone, so export the PNG if you want to keep it.
