I think we may have the color of the back of the book wrong! I don't think it's green at all. (Despite what a particular picture shows)
If it is, it's actually a huge relief to me because the whole purple-green color scheme isn't exactly the most eye-pleasing.
I think it might be a brownish-grey to lighter grey.
Look at the back of the books here:
Definitely grey/brownish-grey. In fact, it seems to match the color of the small posters and banners (Seen next to the Doctor here):
As to why it might look green: Fluorescent lights. If a camera isn't properly set, anything shot under fluorescents will look greenish. I have a film degree, it's something they beat into our heads in school, I'm just surprised I didn't think of it before.
So what do you guys think?
And as for the lens flare. The easiest method is to create new layer, fill it with black, apply a lens flare to that. (And you CAN adjust the distance and angle just by clicking and dragging in the preview scene...you can also adjust the brightness) Then just set the blending options on that layer to screen and scale, adjust, and tweak it until it's perfect. Bingo! Instant lens flare.
