Roll vs ACamViewfinder

Share everyone’s photos with the whole group, in 5 minutes flat. When you’re all in one room - hotel, kitchen table, wedding venue, kid’s birthday - open Roll. Each person picks the photos they want to share. Tap Share. Everyone’s photos merge into one roll and save to every camera roll, full quality, no cloud. No accounts. No upload. No compression. The photos go straight from phone to phone. For the planner of trips. The friend who runs the group chat, books the place, and takes most of the photos. Roll fixes the “wait, can you send me that one of the sunset” moment for the whole group at once. Why Roll * Originals, not re-compressed copies. Full quality. * No ads, ever. No cloud. No accounts. No uploads. * One tap saves everyone’s photos to your camera roll. * Duplicates merge, so the group selfie does not multiply. * The photos you contributed are not re-saved. They are already in your library. * Nothing to set up. Open the app and the room is there. * Works with no internet and no Wi-Fi network. Phones connect directly to each other. What you need * An iPhone on iOS 16.4 or later. * A small group in the same room. * Bluetooth on, and the local network permission granted when iOS asks. What Roll is not * Not a cloud album. * Not a chat app. * Not for sharing with people who are not in the room. Every past roll stays available, with no 48-hour clock. Save past rolls to your camera roll whenever you need them. The transfer experience is identical for everyone. Premium unlocks additional capacity and access to more past rolls.

ACam Viewfinder is a professional camera-department toolkit for filmmakers who work with diopters, Super 35, Full Frame, and ALEXA formats. Download free. Use Quick Diopter, Diopter Result, Depth of Field, and Hyperfocal on set immediately. Unlock ACam Pro once when you need the prep suite. No subscription. No account. Works in airplane mode. Free tools Quick Diopter is the on-set close focus tool. Enter marked focus and target distance to get ideal diopter power, the nearest standard glass (+1/8, +1/4, +1/2, +1, +2, +3), a comparison table of resulting focus distances, and a BEST FIT highlight for the strength to pull from the kit. Results update as you type or tap +/-. Meters or feet. Diopter Result is for kit check. Enter marked focus and a known diopter strength to see the resulting subject distance. Depth of Field shows near, far, and total DOF for a focus mark using the format circle of confusion, plus how much sits in front of the mark and how much sits behind. Built for focus pulls and stop decisions. Hyperfocal gives hyperfocal distance and near limit for near-to-infinity coverage. ACam Pro (lifetime unlock) One non-consumable purchase. Restore on any iPhone or iPad. Precision Mode is offset-aware diopter planning with DOF context. Formats include Super 35, ARRI ALEXA 35 Open Gate, Full Frame, and Large Format / VistaVision. Enter focal length, aperture, marked focus, target distance, and sensor-to-diopter-plane offset in mm. See near and far depth-of-field tolerance. Load a saved lens package to fill the fields. Split Focus returns the focus mark and stop that hold two subject distances. Viewfinder and Split is composition planning: horizontal and vertical FOV, frame width and height at subject distance, and a place-and-rotate split-diopter line for staging notes. This is a planning overlay only, not an optical aberration simulator. Focal Match keeps the same angle of view when you move a lens between formats — horizontal, vertical, or diagonal. Saved Lens Packages store format, focal length, diopter-plane offset, and aperture on the device. Create, edit, delete, and load them into Precision Mode. No cloud. Custom camera formats with your own circle of confusion are included with Pro. Designed for set Offline optics math. No account, no ads, no analytics SDK. Dark cinema-kit UI. Guide on first launch and on every tool. Glove-friendly +/- steppers. Treat offset-aware results as prep estimates until you verify on the glass. Who it is for Focus pullers, 1st ACs, DPs, operators, rental houses, and lens techs. What you pay for Free is Quick Diopter, Diopter Result, Depth of Field, and Hyperfocal. ACam Pro is the prep suite as one lifetime unlock. ACam Viewfinder answers hard focus and framing questions quickly so you can move on with the shot.
