Mr Ron Palgrave

Thank you Robin. You understand my point that the chopping process might be detracting from the usefulness of the image, even though it might look “nicer”. Both images are sharpened. As you suggest, I will check the profile. To be frank, I have no illusions as to my competence at present. But that will come and I do not want my captures to be inherently flawed. Thanks for your help.
