Sharpness of merged photo could be better – Stay Focused Review

Tested the app by taking 3 shots of a ruler at an angle. I found that while it does increase DOF of the merged photo, each part of the merged photo was blurrier than the focused areas of the initial photos. So while it does provide a capability in-phone that doesn't exist today, the merged result could be better. Looking forward to improvements in the merging algorithm to better retain sharpness.
