Re: Recommendation regarding brightness

get a colour card like xrite colour checker and set your exposure and colour balance so the greytones are neutral (i.e. R,G,B all the same value) and set the first grey square to be 200,200,200 etc. See here https://xritephoto.com/ph_product_overview.aspx?ID=820&Action=support&SupportID=5159...

Re: Combining Split output into PDF

What do you mean by 'PDF size 50% JPEG -G4'? by this i mean i store the JPEG at 50% compression which is fine/good enough quality for colour and G4 is group ccitt for binary image.
