Thanks for the reply,
i am using windows 8.1 and have custom camera system selected but still have no slider for brightness.
i have also turned the grid off in settings which has helped alittle but still very pixelated and way too bright , i have played with focus by twisting the lens and is the best it can be.
i have the 8mp camera with 110deg lens , my camera is 90cm above the bed and i have 1300 x 900 bed.
any help would be much appreciated
I have also managed to fix the origin problem in ruida control board.
p.s. lightburn is awesome, i have used a few cad programs in my time and loving lightburn
