Ilford Direct Positive 4x5: Thoughts?

[HaydenKlein]

I recently got a box and I'm excited to shoot with it, anyone have any recommendations, tips, samples, ideas? I know they say to shoot at ASA 6, but I've seen other use different, so feel free to recommend your speed.

Thanks!

They say preflash, I never mastered it.
