I have done some club photography and a friend of mine is still doing it. There is no effect here. These photos look like they come straight off the camera. If you're wondering about the misty feel well that's just the smoke machines. That first picture has a fill flash on the subjects shot from the top down. The second picture uses all natural lighting again.
first of all you need to find a subject that is really conceited and off his chops high on coke.... tell him to spread his arms like a butterfly and then snap away
thanks for the fast reply mate.. But may i ask how do i take pics like this ? any settings on the cam ?
