To be honest i'm a bit stupid 
anyway, looking through the forums i have seen a lot of stuff about 'splitting' the fresnel on the OHp and sticking the LCD in between two fresnels...
have i got this right? can anyone explain the benifits/con of just sticking it on top as opposed ot splitting...?
🙂 help gratefully accepted
