SOMEWHERE hiding in these rocky cliff scenes are two perfectly camouflaged deer.
You could have some seriously impressive vision if you can spot the animals in these two pictures in under five seconds.
At first glance these may look like nothing more than two pictures of a dry hillside - but there is actually more to this scene than meets the eye.
These two klipspringers, a type of small antelope, are found in both eastern and southern Africa.
They blend so effortlessly into their natural environment that they are almost impossible to spot.
Roan du Plessis, 32, captured the baffling snaps while guiding a safari at Ngala Private Game reserve.

Roan, originally from Johannesburg said; "One of my guests actually spotted them first and exclaimed 'What's that?'
"My initial thought was that she might have seen a leopard since that is what we were looking for, but I was pleasantly surprised to see this pair as I haven't seen them in nearly half a year.
"Rocky cliff faces is their natural habitat, with incredible maneuverability on rocky outcrops," Roan continued.
"Although I didn't go into that area specifically looking for klipspringers, once we saw them, I planned on showcasing the incredible camouflage of these tiny antelopes.
