Enter your baseline time, the first max-black step from a wedge where you can not see a line from the transparency or white if you are calibrating polymer, and steps-per-stop—then the app does the maths and records your setup. Made for Cyanotype, Platinum/Palladium, Salt, Carbon, Photopolymer & other alt processes. What it does: Calculates a precise standard exposure from a step wedge. Simple process picker (Cyanotype, Platinum/Palladium, Salt, Carbon, Photopolymer, Other). Optional notes for paper, ink, and aquatint timing. Export your records to Google Sheets (with an included Apps Script you paste once). Newest-first log with pastel row tinting by process. How export works You’ll paste a small, safe Google Apps Script into a Sheet (instructions in-app). Tap Export to push a new row with the date, process, exposure, and notes. The sheet auto-formats and keeps the latest records at the top. Why it helps records exposures across papers and processes A clean archive of what actually worked Subscription Alt Process Exposure Calc uses an auto-renewing yearly subscription for full access (pricing shown in-app). • Payment is charged to your Apple ID at confirmation of purchase. • Subscription renews automatically unless cancelled at least 24 hours before the end of the period. • Manage or cancel in Settings → Apple ID → Subscriptions.
