Which exif viewer are you referring to? If it's exiftool then, like any other exif reader, all the fields are relevant depending upon how much you want/need to know. Surely most of it is self explanatory but if not, rather than give you the low down on every single field, it would be easier if you posted which fields you don't understand or are in need of further clarification. I'll help where I can although some of it is even beyond me in which case another member might know.
From your post though, it read as though NO exif data was available which in fact was not the case.
thanks for you reply forseti, as you know I am a complete idiot, and I dont even know what I want to know It's just that you said that you would explaine the fields that I should be interested in.
Live each day as your last, one day you will be right.
