I feel like I'm chasing my own tail, here.
how to take such photo？
This is a clone shot. I took two separate exposures - one with me in each pose - then I combined the images on separate layers in Photoshop. I added a layer mask to the top photo then applied a gradient to the layer mask so that only the half of the picture with me in it would show up on top of the other picture with me in the other half!
Now what cartoon have I seen this in?
And you have a nice view from behind
