DPReview:

Halide aims to be the ideal, elegant middle ground between ‘too simple’ and ‘airplane cockpit,’ peacefully co-existing with the iPhone’s default Camera app and perhaps occupying at least some of the same muscle memory space.

Halide starts out shooting in smart auto mode, but a single tap calls up a manual mode where you can adjust ISO, shutter speed and white balance. The same gestures you use with the iPhone’s native camera work for Halide, though with some variations.

While much of the Mac Tech Media have raved about Halide from Chroma Noir (App Store affiliate link), I really appreciate DPReview’s hands-on description that includes the pluses and minuses, helping me to make a better buying decision.
