Darkroom is my go-to editing app on the iPhone 8 Plus. The newest update introduces some truly magical editing capabilites for Portrait Mode photos. In addition to new filters that use the depth information of a portrait mode photo, the update has also given us editing tools for independently controlling the brightness, saturation, and blur characteristics of the foreground and background. I couldn't recommend this app more highly.
On the left is a normal portrait mode photo I took of my dog, Lucy. On the right, the same shot, but with one of Darkroom's P400 Portrait filter applied (along with some tweaks to the background blur itself).
Again, on the left, a normal portrait mode photo I took of my breakfast one morning. On the right, that same shot, but with P100 (and various tweaks) applied.
This update is simply another in a long line of great updates to this application. I can't wait to see what's next.
