Thanks for that Jim.
To be honest I was waiting to see how types of software the guys are using all giving a slightly different variation on the same picture. I have also been taking note of the info passed on by Steve to me (Thanks again Steve) and trying to put it into practice......
.
When the guys started talking about Histograms and all them other big words all I could think was "Whoa, wheres my dictionary" and "now where in the loft is my Box Brownie"....
Thanks for your input guys.
