Swifty,
Here are a couple of shots that are typical of my problem. I expect you will be able to extract the exe data from them.


This good looking bloke is me sampling a range of ciders. The only tweaking I have done is to sharpen by two clicks in Lightroom.


This shot is of one of the other tour participants. Once again I adjusted the sharpness by two clicks, leaving all other setting alone.
