Lully's Series Class

I'm signed up to work with Lully Schwatz to do a series of paintings.  She likes to paint in the large format and that's what I'm planning to do because while I was organizing my supplies, I realized I had a lot of large canvases. I love to paint large and haven't done that for a while, so it should be a lot of fun.  My ideas require me to take photos at sunset or sunrise, well, I haven't been able to do that yet, either slept late or there was no sun, and it get's dark so early, it's hard to realize at 3:15 that I should run out and take a sunset photo.
