For the week 5, the exercise was to roto out an image, white balance it and colour grade it correctly to fit in the scene of the second image. I practiced with both still pictures as well as moving picture.
For the stills, I chose this picture of Captain America and decided to put it into this image from “Indiana Jones and the Last Crusade”.
First, I cut out the roto shape, which I then white balanced and colour graded using the information from the second image.
Due to the position of the legs closer to the camera, I had to place the objects in the space between the legs and the background from the second shot. In order to do that, I transformed the colour graded image of Captain America to where I wanted it to be positioned in the second shot and merged together with the roto of blocking subjects in the 2nd shot using the Merge(out) node.
This is how the final shot turned out.
Looking at the final composition, addition of the shadow falling towards camera would have made the shot appear to be more realistic. Below is an image of how the Nuke Script looked like.
In the moving shot I used this poster of Uncle Sam and placed it instead of one of the pictures on the wall, following a very similar path as for the still images.
