ArchCam Support
Choose the automatic correction your subject needs, then fine-tune in Studio Editor when needed. Photo processing stays privately on your iPhone.
Each correction solves a different problem. Verticals and Wide replace one another by default. Allow them together in Settings only when needed.
ArchCam uses camera direction and lens information to calculate a shift-style correction automatically. Verticals corrects converging upright lines caused by pointing the rear camera up or down, not perspective from photographing a wall from one side. At very steep angles it pauses and shows a message.
Wide photos can stretch faces, figures, circles, and other familiar shapes near the frame edges. Wide uses a curved, fisheye-like projection to preserve their proportions more naturally. Because it may curve straight lines, it is better suited to people and organic shapes than architecture.
Level horizon automatically corrects camera tilt. It is useful for most everyday photos unless you want an angled composition. It pauses near a straight-up or straight-down view.
Document mode straightens flat subjects photographed from above with the rear camera. It activates near a straight-down view with Wide off and shows a status label. It corrects geometry; it does not detect page boundaries or recognize text.
Both modes apply the same enabled corrections to the saved photo.
Choose front or rear cameras, tap a zoom button or pinch to zoom, and optionally show exposure and white balance controls in Settings. Tap the shutter or press either iPhone volume button.
Tap the camera image to focus once and select an exposure-priority area. Exposure continues adapting to light. Touch and hold for AE/AF Lock to hold focus distance and exposure; tap again to unlock. With the controls enabled, drag the focus square up or down for exposure and left or right for white balance. You can still change exposure while locked.
Exposure ranges up to -3 to +3 EV, depending on the camera. White balance ranges from 2400 to 10000 K. Tap its thermometer for Auto or hold for lighting presets. Auto centers the slider; it does not display a measured temperature. White balance returns to Auto when you open Review, leave the app, lock the screen, or hide the control.
Capture saves enabled corrections and keeps a recoverable original in the same photo. Settings offers HEIF or JPEG and 1:1, camera-native 4:3 (default), 3:2, or 16:9 output. These aspect ratios do not unlock extra sensor area.
The round camera thumbnail opens Review. Original / ArchCam changes what you see, not what is saved. Save makes the selected version current in Photos. Keep Both adds the alternate version as a separate photo; a second copy is not needed to restore the original later. Share exports a still image of the currently saved version, so save your selection first. All Review actions are free.
In Review and Studio Editor, swipe right for older photos or left for newer ones. Review browses ArchCam photos; Studio browses your accessible library. Review supports landscape viewing without moving its controls and does not zoom the photo.
Tap Edit in Review for Studio Editor. Its tools are Horizon, Vertical, Horizontal, 4-Corner, Wide, and Color. Enabled tools are marked; tap a slider tool to reveal its control. Tap that selected tool again to disable it without forgetting its value. Only one slider is shown at a time; 4-Corner opens guides instead.
4-Corner lets you mark a rectangle distorted by the viewing angle. Apply the guides to make the shape rectangular with horizontal and vertical edges, then fine-tune Horizon and both perspective sliders. Guides define geometry, not the output crop. Always check suggested corners.
Wide starts at its saved setting or the recorded 35 mm-equivalent focal length. If neither is available, it starts at infinity, beyond 200 mm, with no Wide effect. Color restores a saved custom temperature in Kelvin; otherwise 6500 K is a neutral editing reference, not a measured scene temperature.
ArchCam photos open in their saved version with recorded adjustments restored. Other library photos open in Original without new adjustments, using the appearance chosen in Photos, including Portrait blur and lighting. Geometry edits preserve that appearance; ArchCam does not expose Apple's Portrait controls. Editing a Live Photo retains motion and sound. Camera capture produces still photos, not Live Photos.
Studio Save updates the selected version without closing the editor. Saving Original retains the adjustment recipe for later use. Rewind restores currently saved adjustment settings. Leaving with unsaved edits offers Save, Discard Changes, or Keep Editing; interrupted edits can be resumed.
Studio Editor and Artwork capture share 10 free saves. A one-time Studio purchase removes the save limit; it is not a subscription. Previewing and adjusting do not use saves. Use Review for free changes between already recorded Original and ArchCam versions. Purchase or restore Studio in Settings > Studio Settings using the Apple Account used for the purchase.
Include your iPhone model, iOS version, ArchCam version, and a short description of what happened. Do not send private photos unless they are necessary to explain the issue.
