## What is GroundGlass?

GroundGlass is a shooting log app built for large format photographers.

Whether you shoot 4x5, 8x10 or any other format, GroundGlass captures every detail of the moment you press the shutter — from exposure settings and Zone System metering to camera movements and development records.

KEY FEATURES

◆ Complete shooting records — Camera, lens, aperture, shutter, film, filters and movements, all in one place. Effective aperture is calculated automatically from bellows extension; holder numbers are one tap away.

◆ Zone System metering — Full metering workflow in the spirit of Ansel Adams: multiple readings, base subject selection, exposure decisions, with the zone distribution at a glance. Includes a built-in spot meter with pinch zoom.

◆ iCloud Sync — Records and equipment sync across your devices through your private iCloud database. Switch phones without worry. The developer has no access to your data.

◆ Film workflow — Record status (Shot → Developed → Scanned), film holder management, stock tracking with automatic sheet deduction, and batch development entry. From loading to archiving, everything is on file.

◆ Record templates — Save your go-to camera/lens/film combinations and apply them with one tap.

◆ PDF export — Index label PDFs for film sleeves and full-page record archive PDFs, with preview before sharing.

◆ Statistics & analysis — Shooting trends, gear usage, parameter distributions and a shooting calendar heat map, exportable as a report.

◆ Shooting map — All geotagged records gathered on one map. Revisit your footsteps.

◆ Calculators — Reciprocity failure, bellows exposure compensation, and depth of field with per-format circle of confusion presets.

◆ Extensive equipment database — About 180 large format camera models from 25 brands, including Linhof, Sinar, Arca-Swiss, Chamonix and Ebony. Lens presets from Schneider, Rodenstock, Fujinon, Nikkor and more.

◆ Professional filter management — Structured selection by brand, type and strength, including center filters, with automatic stacked compensation.

◆ Map-based location — One-tap locate, with reverse geocoding for place names and coordinates.

◆ Data backup — JSON import/export, with or without photos. Your data is always yours.

◆ Darkroom-themed interface — Amber-toned design with card layouts, made for photographers.

Your data lives on your device and in your private iCloud database. We collect no personal information.

Large format photography begins with a record.

## Version history (last 5 releases)

### 4.9 — 2026-08-10

GroundGlass 4.9

NEW
· Receive a frame from FieldGlass: tap “Log in GroundGlass” in the FieldGlass gallery to open a prefilled new record — camera, lens, focal length, date, place, coordinates, notes, rise/shift, and the scene photo. Confirm to save; cancel leaves nothing behind. Aperture and shutter are never filled in (FieldGlass doesn’t meter).

· Expanded large-format gear: more classic lenses (including Goerz, Zeiss Protar, Voigtländer) plus cameras from Chroma, Richard Ritter, Stenopeika, and Walker.

FIXED
· Corrected image-circle values for several lenses (including inaccurate Voigtländer data).
· Reordered some camera models so related bodies sit together in the list.

### 4.8.1 — 2026-08-04

GroundGlass 4.8.1:

• Reciprocity reminder in the light meter
When the calculated shutter is 1 second or longer, a tip opens the reciprocity calculator with that time already selected.

• Records missing exposure are marked in the list
So a default “ISO 100” no longer looks like a completed exposure.

• Zone metering PDF fix
Zone data no longer disappears from PDF export for some older language formats; label PDFs now show the final EV correctly.

Thanks for using GroundGlass!

### 4.8 — 2026-07-31

GroundGlass 4.8:

• Tools panel
The wrench menu is now a grid. Lens image-circle lookup and film stock are reachable from the home screen.

• Appearance
Choose System, Light, or Dark in Settings.

• Tools that know your gear
Reciprocity pins films you own or stock; image-circle lookup can start from My Lenses.

• Calculators ↔ records
Create a record from exposure compensation, bellows, or DOF results; open those calculators from focus distance and bellows fields in the form.

• Remembered inputs
Light-meter ISO, DOF settings, bellows focal length, and reciprocity film type persist between sessions.

• Fixes
Short-exposure reciprocity under-compensation corrected (measured TRI-X / T-MAX tables now take priority); duplicating a record keeps its project; cancel confirms on new records and reverts edits; plus iOS 26 toolbar, empty cards, and bipolar movement-slider fixes.

Thanks for using GroundGlass—feedback welcome!

### 4.7 — 2026-07-21

GroundGlass 4.7 highlights:

• Home Screen & Lock Screen Widgets
See loaded film holders, overdue reminders, and days since your last shot at a glance.

• Long Exposure Countdown
A big, clear countdown with haptics and sound, plus Live Activity and Dynamic Island support—track your exposure right from the Lock Screen.

• Zone Metering, Redesigned
Guided entry for shadows, highlights, and reference points; automatic Zone III shadow placement, contrast analysis with N± development suggestions, and ISO-based exposure combos you can apply to aperture and shutter in one tap.

• Light Meter Upgrades
Shutter range extended to 16 minutes, improved spot metering accuracy, and one-tap record creation from a reading.

• Refreshed Calculators
Exposure compensation, depth of field, and tilt/swing calculators get a cleaner layout with a live Scheimpflug diagram; reciprocity results can launch the countdown directly.

• More
Widgets deep-link into film holder management, reminder settings now live on the holder page, batch loading covers all holders, plus many fixes and refinements.

### 4.6 — 2026-07-02

• Lens image circle lookup fully upgraded: complete specifications (optical construction, coverage angle, filter size, shutter, weight) with separate entries for aperture variants
• New optical construction diagrams, accurately drawn per design type
• Coverage diagram now compares 17 formats (4x5 up to 20x24, plus 612/617) with tap-to-select chips, max coverable format, and movement margins
• Share lookup results as beautiful cards
• Smart coverage check: when a record has both a film holder and a lens, the app verifies the image circle covers your format
• Film holder upgrades: format badges, loaded-days display, batch loading, and optional overdue reminders (7/14/30 days)
• New development index (N / N+1 / N-1) shown in list and details
• Faster input for cameras, films, and filters with quick-pick menus and auto-filled parameters; expanded built-in film catalog
• Equipment lists sorted by name with defaults pinned; backups now include holders, film stock, and templates
• Various UI refinements and stability improvements
