One of my favorite projects so far has been forced perspective. My favorite photo definitely had to be the one that makes me look like I'm running on top of a bench.
This photo wasn't really that difficult seeming how we got lucky and it matched up perfectly on the first time. Though, we thought about this idea early and thought it would work with a fence. The fence however was too tall for me to be able to jump and make it look like I'm walking on it. We decided to give up on the idea and think of something else but when we found the bench we came back to the idea and it worked perfectly!
This next photo is also a favorite. It wasn't really that difficult to pull off though. The only issue was that if you didn't angle the camera right you could see my hand which didn't make the photo look like a forced perspective. We also didn't want to spill the drink so trying to hold the drink in one hand and taking the picture in the other without spilling it did get a little tricky.
