Hi Diane,
Thanks for the reply.
Quite possibly, that is exactly what I may have done.
To be honest, I can't remember as it is a while ago since
I spotted this problem, and it is only now that I've had time to get
around to trying to solve it.
I have PS on my system and I have done the 'save as' with some
pictures a few times, so it could be the solution to the problem.
I will try on an old and unwanted shot to save in PS and then go back to LR
and see the results. Will report back the findings.
I appreciate your interest and advice. Thanks.
Rob
