Thanks both!
Ian I'll be in touch via PM
Mark - yes digital. How many? - well given that about 30% of the brief is troughs and sinks I guess about 60 images total. This allows for discarding a few which don't fit my 'storyline' and combining some in compostite slides. I'm hopeful that Ians will make up a bit more than half, good practical stuff. If you have some of different types of troughs and established troughs they would compliment Ians nicely. What do you think?
