I use 171.
I'm no help.![]()
I use 120. I just like the look. It looks more natural to me as I'm working. No particular reason beyond that. I don't look at someone's page and say their shadows are at the wrong angle, I just like mine at 120 or there abouts...
I usually use 45 but I have played with other angles. Sometimes the elements in the kit, the photo, or the theme lends itself to another angle. A few of my layouts are a bit shadow-schizo and use a few different angles within the same page. I just do what looks right to me sometimes.![]()
