Well thats really gone and done it now, I also have two images  i was going to post Mod 2 tomorrow but I think i will wait for a reply.
I have taken 2 images at the far end of the range of my camera,(it does say "maximum detail")after finding out what my camera is capable of,so my shadow detail image shows a burnt out sky,and my highlight shows good sky image but not much in the way of foreground.
I am thinking that I could be doing this again, is this is what is required or have I got it wrong.
If I am being stupid.....I'll get my coat

That's how I read it as well

Garry
could i have some direction on this please, not sure if what i have done is the right thing, does the image need to be a straight forward shot with exposure biased towards the highlight/shadow, or do we need to achieve maximum detail in both images?.
HELP!!

Ok analogy time then!
Imagine the tones in your subject are a train - 8 carriages long and you have a platform (that's your sensor) that can accommodate 12 carriages. Well you have a choice then as to where on the platform you pull the train up but wherever you stop all the passengers can get off the train - in other words all the range of tones can be recorded by the sensor.
Reverse that scenario, where the platform is shorter than the train, and some passengers are going to find it tricky to get off the train - in other words not all your tones can be recorded.
So faced with the first scene you can record all tones at each of the two exposures but there will be a bias towards highlight or shadow. In the second there will be a sacrifice at one or other end.
And that's why it isn't possible to give an answer until you find your scene and photograph it. It's a dilemma photographers have faced since the beginning of photographic time and one they've all learned to deal with and this exercise sets you on the way.
Hope that sort of helps!

The expenses are tempting but you have to wear a tie.
