Juwajom
Read full descriptionHide full description
Juwajom is a local darkroom for stills. Capture or import a plate, lay one of seventeen composition guides on the frame, write what you see, and save a composition review print on this iPhone. The work happens on the photograph. Guides such as Rule of Thirds, Phi Grid, Golden Spiral, Diagonal Method, and Vanishing Point sit on the plate. Opacity, offset, scale, and line weight are camera dials, not a separate worksheet. Previewing a guide does not use a credit. When the observation is ready, one Composition Review Credit writes a PNG print. Credits stay on this device. Clearing all local data or removing the app deletes remaining credits. Juwajom does not post photos and does not connect to a Juwajom server to save records. Camera, Photos, and Microphone are requested only after you tap Capture Plate, Import Plate, Save to Photos, or Record Observation. You can refuse any of these and keep the other path that still works.
