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 You may...

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. You can see in my previous post example of 50% jpeg on text up close, the fuzzies.... higher quality doesn't have this ...

Re: Combining Split output into PDF

Hmm after some tests It appears FineReader if the (undocumented) 'Mixed Raster' Option is ticked, will produce a PDF with binary and colour components on the same page, reducing the filesize significantly.
