Hi Geoff,
Well mate I had a look at this chap Sandy Mcguffog's writing and explanation 
and I did exactly what I always do when attempting to cope with all the 
tests, theories etc about digital cameras! I read, I forget! Moved on. WHY?

Well first off he was using words I had no idea what he was talking about 
because I'm a photographer and not a technician! :-)

So my plan is staying with what's been successful so far and that is? I'll 
carry on exactly the way I have since my first encounter with digital 
cameras. set the ISO, look through view finder, if all looks cool... "PRESS 
THE BLOODY BUTTON!" ;-)

Oh well it's me and digi stuff, I have tried to understand all the terms and 
words I've never seen before and certainly have no idea what they mean. So 
it's much easier to set most things to auto whatever and take pictures. It 
has worked so far during night and day, hardly any light and lots of light. 
In the rain, snow and sleet, heat and cold, inside and out. I guess I work 
on the basis of the less you fiddle, the less screw-ups you'll have. :-)

Thanks for the heads-up on the article even though it scared the hell out of 
me thinking "maybe I should really try this stuff?" Then closed the computer 
screen with... "Oh well another day." ;-)
Thanks Mate! :-)

cheers,
ted
