Halide III just got its iPhone Duo update with re-worked controls for the new screen formats and a feature that Apple’s native camera app left out: a waist-level viewfinder. When you use the phone in its L-shaped pose the image preview will appear on the top portion of the screen. I was hoping I’d be able to move the preview to the lower half of the screen and use it like a classic Hasselblad camera. It’s a nerdy little detail, but Halide is made by nerds, for nerds, and I appreciate that.
