Murray, clean negatives, it's one of the areas I need to be more vigilant with, I have my scanner set up in my study were my PC is, it seems the sensible place for it. Unfortunately we have two cats and the older one is my constant companion, in fact I don't even notice her now as she seems to be permanently on my lap. There are cat hairs all over my desk and keyboard, I have tried banning her from my study but she takes no notice.
The other thing I need to address is my negative holder, it works well but I need some referencing method as it's difficult to get the negative strip to stay in place while I close the top down.
Always improvements to be made, Dai.
