"I shoot film and digital - just trying to guess where this might be going... Computers are a love/hate thing, more of the latter at the moment... Like I said maybe reading more into this than I should be..".

Steve you kind of guessed where this was going. Someone posted the same question on an analog forum I frequent where digital is the devil. A lot of large format users there. Many people mix their own chemicals and coat their own paper. So you get the picture. Anyway I figured most of the people would report charcoal. To my surprise over half the people responded wood saying charcoal wasn't the real thing the other half, except for me, said charcoal. There were about 25 responses. I figured I'd ask here where probably half if not more of the people shoot digital to see the response. To early to tell but my guess was correct propane is king. Curious to hear some more responses.
