AFTER - Edited with PS Express.  I used a duo-tone (magenta/green) filter and added a spotlight and halo effect, to add drama.  The after picture looks like the photo could have been taken in the dark, using an infra red lens.

BEFORE - Patio and backyard on a sunny day. 

AFTER - I used both Snapseed (IOS) and Paint 3D (desktop) to change the feel of this picture.  With Snapseed, I used the brush (saturation of +25) and the 'drama' filter # 2.

Then, I used Paint 3D to add the graininess (Zeke) and added the butterflies. The overall effect is that this scene became apocaliptic and burned out, with a Southwestern vibe.

BEFORE - An everyday picture of the mailbox on schist and mortar wall.

AFTER - This photo was edited with PS Express, using overlays of fire and auto-enhance. The overall effect is that the mailbox was opened and the flames started to shoot out.
