So, effects wise, I've been looking at possibly using smoke grenades during a photo shoot outdoors using Enola Gaye smoke bombs. The WP40 looks interesting as well as the EG18X.
If anyone has ever used these, please post some photos of your results.
I will buy a couple myself and share my results.
Also, they come in different colors. I'm guessing the difference in colors would affect black and white processing. From what I've seen they come in army green, orange, white and yellow. I'm still researching these so they may come inore colors. I haven't seen them yet.
