Today I took some toy soldiers and a tank and shovelled some dirt into a baking tray and lit some potassium nitrate smoke bombs.
The results came out ok but also showed me that there was dust on the D7000 sensor that I hadn't noticed before since I was shooting at f11 to get more depth of field with the smaller subjects and closer focusing.
The soldier didn't look so good, I needed to shave off the plastic moulding around him to make it look more real. Initially I had the scene located inside the garage, watched by Oprah, a very talkative black cat. She doesn't mind smoke and flames, she just moves a little further away when things get too smokey.
Then I took the toy tank and set it at an angle to look like it was being viewed from lower down, hopefully to make it look more real. I experimented with various settings ranging from 1/500th to 1 second to add some blur to the smoke as well.
It was lost of fun and luckily the neighbours didn't call the fire department, or police for now...
As usual with most of my shoots I had the extractor fan going to clear away the smoke :)
