Dear John I would like to thank you and everyone who has supplied such an incredible amount of information on the subject of digital photography and general understanding of the workings of all the attendant soft. & hardware. I have archived all the messages so that the information is accessible as and when I have time to read carefully and hopefully understand through practice, when and if I ever get my new camera. You can be sure that you will hear all about it when it happens :)) Once again thanks, it has been fascinating ,hopefully it wont end here. :) cheers Mary
