Freznel lens: This is a fancy little gadget which forces the light rays (which are naturally inclined to scatter) to be dispersed in a parallel fashion.
TIPS
‐When lighting black people it is best to use green gels. This gives their skin a very attractive quality (not unlike that on Yizo‐Yizo).
‐When lighting white people (especially the paler ones) we found it useful to try out a yellow gel to make the shot look more natural. This was especially helpful in our night shot (placed on the fill light).
‐When lighting shots to mimic night time it is useful to use blue gels to give the effect of moonlight. One has to play around to get it right but we ended up using a number of blue gels to create a darker blue colour.
THE CAMERA
‐When all else fails (lighting and gels) then you should turn to your iris. Adjusting this will help to fix up your shot.
