Hey Jocko you have nothing to be apologizing for

I like to see how others are working and what they are doing. 

I used a flash gun triggered for the time of impact similar to what mcv has mentioned above. My reservation with using lots of lights around a pile of flour is: Be Careful !   

If you get a lot of heat and a fine combustible powder it is the recipe for an explosion !

Keep sharing your methods, I think there is something of interest to everyone in the way others get their shots and what they are doing right now. 

And every one said, 'If we only live,
We too will go to sea in a Sieve,---
To the hills of the Chankly Bore!'
Far and few, far and few, Are the lands where the Jumblies live;
Their heads are green, and their hands are blue, And they went to sea in a Sieve.
