Painting a bump map

PostThu Dec 14, 2017 1:31 pm

Hi guys,

I have a cut out of a person made in Photoshop. I want to bring to the Fusion to create a parallax effect with it. The thing is, when I start bobing the camera to the sides, obviously, the cutout looks like a cutout (duuuuh). Has any of you guys ever painted a bump mask on top of the photo?How would you approach it?

Depth map painting can be a laborious process. I usually start by drawing shapes around the major shapes: Head, neck, torso, arms, legs, and use some blurs and remasking to get a sort of "balloon animal" shape to start with. A Brightness Contrast node after each piece helps to keep them connected since the blurs will tend to change the brightness of each edge to a different degree. Then I use smaller rotoshapes for sculpting. Sometimes these shapes get merged on top of the form, and sometimes they're used as a mask on a BC node, depending on exactly what I'm doing. A final BC node at the end of the entire chain can be used to control the overall depth and position in your composition. This depth map is used with Displace3D to distort a card to the desired shape.

Thankfully I haven't been on a stereo conversion job in a while; I don't miss it at all!
