Recognizing the answer to this might differ depending on the media you're drawing for, but...

I was wondering what zoom levels people use to paint on? Do you create a huge file (300dpi, 5000x5000 pixels) or just a small one, 1:1 with your screen resolution? Do you zoom out to 50%, or 25%?

Let's assume this is just for a random idea that you'd like to get out of your brain and onto the screen.

Just a general idea would be great, as I realize different programs render zoom levels differently (as in: Photoshop has some issues with layer placement on certain zoom levels, and aliasing discrepancies as well)

Cheers!
