## What is Rollvane?

Rollvane is a calm, single-purpose exposure helper and roll log for film photographers. Pick a lighting condition, pick your film ISO, and Rollvane gives you the correct aperture and shutter pairs straight from Sunny-16. Then log every frame as you shoot it so the roll comes back from the lab with notes that actually mean something.

WHY ROLLVANE
- The Sunny-16 rule is the simplest light meter in the world, but it lives in your head and not on your phone. Rollvane prints the answer in big numbers.
- Picking the wrong shutter for the wrong ISO is why so many handheld frames blur or get muddy in the highlights. Rollvane keeps you on a known-good pair.
- A roll comes back six months later and you have no idea what you shot. Rollvane logs subject, aperture, shutter, condition, and push/pull per frame.

WHAT YOU GET
- Five lighting conditions: Bright Sun, Hazy, Cloudy Bright, Open Shade, Heavy Overcast - each mapped to the Sunny-16 reference aperture.
- Seven film speeds: 50, 100, 200, 400, 800, 1600, 3200.
- Equivalent pair grid: for any condition + ISO, see every valid aperture+shutter combo from f/1.4 to f/22 across 1/15 to 1/2000.
- A standalone Exposure Helper tab for quick lookups when you don't want to start a roll.
- A 36-frame visual grid per roll. Empty frame? Tap +. Already exposed? Tap to review.
- Per-frame metadata: condition, aperture, shutter, ISO, push/pull EV, subject, notes.
- Push/pull tracking so you can mark "+1 stop" on a frame for development time.
- Mark a roll Finished, Re-open it, or delete it. Active and Archived sections keep your workflow clean.

BUNDLED LIBRARIES
- 30+ popular film stocks: Portra, Tri-X, HP5+, Delta, T-Max, Acros II, Provia, Velvia, Ektar, ColorPlus, Gold, CineStill, Lomography, Kentmere, Fomapan, Ferrania, more.
- 25 popular cameras: Pentax K1000, Nikon F3, Canon AE-1, Leica M6, Olympus OM-1, Mamiya 7, Hasselblad 500C/M, Rolleiflex, Yashica Mat, and more across 35mm, medium format, large format, half-frame, rangefinder, and point-and-shoot.

PRIVATE BY DESIGN
Rollvane has no account, no ads, no analytics, no tracking, no subscription, and no developer backend. The math, the bundled film and camera lists, and your roll history all live on your device and stay there. No camera, no microphone, no location.

ONE-TIME PURCHASE
Rollvane is a single $0.99 purchase. No in-app purchases. No upsells. No daily limits. The features above are the whole product.

GREAT FOR
- Anyone shooting an all-manual SLR (K1000, FM2, OM-1) without a meter.
- Anyone whose handheld meter battery died on a trip and Sunny-16 is the backup.
- Anyone who wants their roll to come back with frame notes attached.
- Photo students and Sunny-16 self-teachers.

Open Rollvane, pick a condition, pick your ISO, and shoot. The right pair is already on screen.


## Version history (last 5 releases)

### 2.0.1 — 2026-06-26

This update sharpens the interface: the iPad layout now uses a centered, comfortable reading width instead of stretching edge to edge, plus small display fixes. iPhone is unchanged.

### 2.0 — 2026-06-21

Rollvane 2.0 — a pro upgrade for film shooters, still 100% offline.

• Depth-of-Field & Hyperfocal: format-aware near/far/hyperfocal distances with a proportional sharp-zone bar, across 7 film formats.
• Push/Pull development engine: real development-time multipliers per stop (not just "+1 stop"), with rated ISO.
• Per-frame lens, focal length, and focus-distance logging, exported in CSV and the dev sheet.
• EV → equivalent-exposure converter.
• Flash calculator with guide-number math.
• A bundled 20-lens library and a feet/metres preference.

No account, no network — every calculation and your whole roll log stay on your device.

### 1.2 — 2026-06-15

What's New in Rollvane 1.2

Filter Compensation Calculator (new tab)
Film photographers who shoot with optical filters - colored B&W contrast filters, ND filters, polarizers - now have a dedicated tool for calculating the exact exposure compensation. Pick your lighting condition and ISO, then pick a filter from the bundled library of 21 filters (Yellow, Orange, Red, Deep Red, Green, Blue, ND2 through ND1000, Circular and Linear Polarizer, Infrared R72, and more). Rollvane shows the uncompensated Sunny-16 pair next to the corrected pair, with every equivalent filtered aperture+shutter combination in a grid. If the compensated shutter lands at 1 second or longer, a reciprocity warning prompts you to cross-check the Reciprocity tab.

Filter field on each frame
The Frame Editor now has an optional Filter field so you can note which filter was on the lens for any exposure - e.g. "Yellow", "ND8", "Polarizer". The filter appears in the Dev Sheet and in the CSV export (new `filter` column). The frame grid shows a small indicator on any logged frame that has a filter noted.

Filter data sourced from:
Kodak Professional Photoguide (R-28), Hoya filter specifications, Ilford "Filters for Black-and-White Photography" tech note. Authoritative stop values for all major filter types.

### 1.1 — 2026-06-14

What's New in Rollvane 1.1

Reciprocity Failure Calculator
Long exposures need extra time because film's reciprocity law breaks down at 1 second and beyond. The new Reciprocity tab corrects your metered time for 30+ film stocks using manufacturer-published power-law data (Ilford's 2024 data sheet, Kodak Professional guides, Fujifilm data). Pick your stock and metered time; the full correction table updates instantly. Fuji Acros II is correctly flagged as exempt — no correction needed up to 2 minutes.

Roll Stats
After logging frames, each roll now shows a light-condition distribution (with progress bars) and an aperture spread chart. See at a glance whether you shot mostly in open shade or cloudy bright, and which apertures you reached for most.

Export: Dev Sheet and CSV
Two new export buttons appear on every roll with logged frames. Dev Sheet generates a plain-text development note — it reads your per-frame EV compensation, works out the overall push/pull stop count, prints the resulting development instruction, and appends the full frame log. Hand it to your lab or paste it into your darkroom notes. CSV exports all frame metadata (aperture, shutter, condition, subject, ISO 8601 timestamp, and more) in a format compatible with Lightroom, Capture One, or any spreadsheet.

### 1.0 — 2026-06-10

No release notes.
