Tintava LUT Proofs

See what your LUTs actually do before choosing a look. Tintava brings multiple 3D .cube files and still images into one local visual audition session, then creates real PNG results and a PDF proof book. COMPARE LOOKS TOGETHER Import JPEG, PNG or HEIC stills from Files or choose specific photos with the system picker. Add your own 3D .cube LUTs. The look grid applies each table to the same selected working image, with the source beside the alternatives. Choose a look and drag the source/result divider. On iPad, keep the look grid and selected comparison side by side. KEEP A REPEATABLE SESSION Choose LUT strength from 0–100%. Keep up to 12 saved sessions, 12 source images and 8 LUTs per session. Session names, notes, selected source, LUT and strength persist locally. Save and remove up to 20 named setup presets per session. Reopen sessions and remove their local files. A fresh install starts empty; an optional original ceramics sample with five original example LUTs tests the same processing and delivery flow. READ THE ACTUAL TABLE Inspect cube dimensions, sample count, input domain and table vertices outside 0–1. Tintava supports red-fastest 3D .cube tables of size 2–65, DOMAIN_MIN/MAX or LUT_3D_INPUT_RANGE. Table values and domain endpoints must be finite and between −16 and 16. It uses trilinear interpolation, mixes the result with the source by your strength setting, and clamps rendered values to 0–1. EXPORT A PROOF YOU CAN INSPECT Render all looks or the selected LUT across every source in the session. Share a ZIP with rendered PNGs, normalized source PNGs, the chosen original LUT files, LookProofs.pdf, Manifest.csv, Session.json and Readme. The CSV records source/look names, strength, dimensions and clamped-pixel counts. Preview the actual PDF and share with the native share sheet. One upfront purchase includes every feature. No subscription, in-app purchases, account, advertising, analytics, tracking or developer-operated upload. WORKING-COPY SCOPE Images are oriented, flattened onto white, converted to 8-bit sRGB and normalized to a longest edge of up to 2048 pixels. Originals and camera metadata are not retained. Keep your originals separately. Up to 60 MiB / 100 megapixels per imported still, 32 megapixels per session and 400 MiB working library (exports require additional space). Each LUT up to 16 MiB. Available device space is required. Use LUTs that expect these display-referred sRGB inputs. No RAW development, video, HDR, camera-log conversion, 1D shapers, LUT authoring, ICC soft proof or calibrated color guarantee. Results can differ from other applications or display conditions. PDF images are fitted previews; use PNGs for output detail. Session.json documents the setup; ZIP is not an in-app backup or restore format. Source images, LUTs, session names and notes are included in the export. Review the package before sharing. Only import images and LUTs you have permission to use. System backups follow device settings.
