I currently use MTP wich is a Multicam variant and I played in a field similar to your picture yesterday. Dark Woods with dark green or dark brown dominant. Fields with light green grass, light brown vegetation, sandy colors. One of my buddies uses MTP, I kept losing him whenever he stopped moving
I had no problem finding the enemy who where using dpm, flecktarn, Cadpat, all good camo's in my book. MC and MTP are good at tricking the part of the mind that finds patterns. It's also good whenever you cross over from dark to light surroundings. Most of the darker camo's are good in dark surroundings if you dont move, but are not as good in lighter environments like grasslands.
