[Roundabout]

Thanks everyone.

Yes, the first few images seem to be free from the 'reticulation' (I've learned a new word, thanks). Then it kicks in around image/s 7-10 and continues throughout the film to a greater or lesser degree. One or two images after this appear less or unaffected, but perhaps it is just more obvious on certain types of image.

So, I'm probaly safe using the rest of the batch? I'll probably keep them aside for less 'crucial' work, just in case.
