i know i know (b4 i get BBQed. :P )
been searching for the past 3 hrs but i think the thread has been deleted by the TS.

I remembered TS said that 1 way of removing the smoke is to take a shot before the FW starts n once u did that,stop adjusting the tripod/lens.use ur the FW pics n the pre-shot n join them together,adjusting the pre-shot pic till the smoke in the FW is "covered" up.(or something like that.)

anyone knows how is this done?

thanks for the help.
