Almost 5:00 and no photo yet- am I getting burned out? I hope not! I took a bit of time to follow the light around my house (always my last ditch effort) and came up with some interesting shots of light and lines.
Here is the ceiling above my stairs- turned into a black and white to emphasize the lines:
And here is the afternoon light coming through the blinds and hitting a spider plant:

Fascinating shots! I never would have guessed the first one. You’re right, it’s perfect for black and white. The light bulb looks almost like a giant drop of some sort. Fascinating with curves and shadows and lines and convergences.
The second one is equally fascinating. The reflections on the leaves create another mysterious shot. Nice job. Both very abstract.
Very creative.
