One of the 3 birds (the Victoria's Riflebird) we've selected for the film has bright blue, iridescent feathers on its neck and chest. I want to somehow make this seem iridescent for the film, so I did a little after effects test:
I didn't really know how to approach this, except that it would be some sort of effect added on to the flat coloured animation.
Mat showed me that I could edit the material properties of a layer to make it more metal, and I combined this with a stationary After Effects spotlight to give the illusion of iridescence (as the shape moves closer to the light, the spotlight's bright blue light becomes more appararent making it seem to flash brightly).
For this test, I just animated a shape moving irratically to simulate the bird's movements, and also created a texture overlay to add as well as some roughness to get more of an idea of what the final outcome would look like. I think this ended up being really successful, and the use of the texture definitely helps with making it not too digital looking.
Here is the texture animation:
I really enjoy little After Effects tests like this, and each one helps me understand a part of the software a bit more in depth. Using lights isn't something I've incoporated into an actual project yet, so this is great practice, and I can see myself adding these types of effects in future projects to make 2D animation feel more polished.
