ObscuraFlex is a camera app designed for use with the ObscuraFlex™ large format camera viewfinder adapter for cameras including 4x5 Graflex, Linhof, Chamonix, and some vintage Polaroid cameras.
The app provides a high resolution live feed of your large format camera's image plane (ie: ground glass) rotated to reverse the upside-down image created by any traditional optical system.
When using the camera adapter as a composition and focusing aid for large format film photography the ObscuraFlex™ provides a greater level of detail and clarity than working with a standard ground glass, and with an image that's right-side-up!
You can also use the adapter with this app (or other camera app) to shoot stills, video, or reference images to accompany your film negatives.
Ratings & Reviews
Fixed a bug that caused manual exposure controls to be ignored.
Known issue: "Auto Zoom Reset" fails to complete before shutter release if zoom level is extreme.
Workaround: Take a second exposure after zoom reset completes, or manually reset extreme zooms.
