MatGlass vs ZoneCalc

MatGlass is a framing studio for photographers and art lovers. Before you print, see the finished piece on iPhone or iPad: choose a frame, lay the mat, add glazing, then hang the work at true size in a room — every wall has a real width and light, so shadows follow the windows and lamps. Group several pieces into a photo wall, preview the whole arrangement, and export a spec sheet a print shop can follow, plus a hanging guide marked nail by nail. — Rooms — • A hundred-plus realistic rooms in a dozen-plus categories, and growing: living rooms, bedrooms, galleries, studies, dining rooms, and more • Each wall is marked with its true width, a hangable area, and where the light comes from; the piece hangs at real size, at standing eye level • Or use a photo of your own wall; after a three-step calibration it hangs at the same true scale — Framing — • 30 frame finishes: classic woods, brushed metals, European carving, Chinese hardwoods • 11 mounts: window mat, float, floater frame, glass sandwich, shadow box, acrylic face-mount, gallery wrap, dry mount, hanging scroll, and more • Mat styles: single / double / triple, museum, weighted bottom, oriental proportions, French mat, float • Multi-opening mats: 2 to 6 windows in one board — grid, stack, diagonal, staircase, hero, and more — with adjustable gaps and margins • Layered mats: width, colour, and bevel set per layer • Deckle edges, paper borders, and a signature, all adjustable to the millimetre (inches too) • Enlarge a corner sample, the way you would in a framing shop — Smart & efficient — • Smart colour: pull a palette from the photo and build a full mat + frame + wall scheme in one tap (Pro) • Materials & cost: usage from the same sizes as the preview; you enter the unit prices; export with the spec sheet (Pro) • Print-quality check: DPI updates with the output size, and warns if it falls below press standard • Undo / redo, variant compare, save and share framing presets • 12 built-in samples so you can see the styles at a glance — Photo wall (Pro) — • Arrange several pieces freely, at millimetre-true scale • 14 layout templates, plus auto-arrange; adjustable grid snap and alignment guides • Hang them in the rooms above, or on a photo of your own wall • Export the mock-up, a full spec sheet, and a hanging-guide PDF in one go (single-nail cord or two D-rings) — Preview & export — • Live 3D preview, with real shadow and depth • Hold the peek control while you design to see frame thickness; the layout itself never tilts • Showcase: four camera angles, drag to look around, export at original / 1:1 / 4:5 / 9:16 (Pro) • AR preview: place the framed piece in a real room (Pro) • Export a high-resolution image to Photos or share it; spec-sheet PDF in millimetres and inches (Pro) — Data — • Unlimited local saves; one-tap backup and restore (.matglass archive) • Fully offline.

ZoneCalc — Zone System Calculator ZoneCalc is a precision tool for large format, medium format and 35 mm photography following Ansel Adams' Zone System. Built for photographers who work with a spot meter, develop their own negatives, and want full control over exposure and tonal placement. METERING In Classic mode, enter the shutter speed for the deepest shadow with detail (Zone II) and the brightest highlight with detail (Zone VIII). ZoneCalc returns the shutter speed for Zone V — 18 % middle gray — the exposure you set on the camera. Multi mode accepts any number of measurement points across the scene. The app auto-assigns each point to a zone; drag pins on the zone strip to express your creative placement intent. RECIPROCITY For exposures above one second, the Schwarzschild effect is corrected automatically: t_corr = t_nom ^ p, using the film-specific exponent. The corrected camera time appears directly in the result card. The shutter speed list extends to 30 minutes. Films with reciprocity data: Ilford HP5+, FP4+, Delta 100/400, Kodak Tri-X, T-Max 100/400, Kodak Portra 160/400/800, Leica Monopan. N-RATING & DEVELOPMENT ZoneCalc compares the scene's dynamic range against the film's usable latitude and proposes a development adjustment — N−2 through N+2. For each film, concrete times are shown for common developers: D-76, Rodinal, HC-110, XTOL, ID-11, T-Max Dev — with dilutions per Massive Dev Chart and manufacturer recommendations. HISTORY & EXPORT Every calculation can be saved with a note and the chosen developer; two entries can be compared side by side. The complete result — shutter speed, reciprocity, N-rating and development times — exports as an image for the darkroom or for sharing via AirDrop, message or mail. DESIGN The interface follows the visual language of classic Leica instruments: monospaced typography, warm amber accent, hard edges instead of rounded corners. Fully localized in English and German, all-dark throughout — optimized for darkroom and field use. ZONECALC PRO Classic two-point metering with Zone V calculation and the zone strip are free. The one-time Pro upgrade unlocks: — Multi-point metering with interactive zone assignment — Reciprocity correction and N-rating — Development recommendations with times per developer — Save, compare and image export One app, no subscriptions, no data collection. All calculations run locally on device.
