I am new to photography and have just finished doing my first ever grey scale test to figure out the dynamic range of my camera when I had a thought.

Would the dynamic range of my camera change if I increased the ISO?

I have a Canon 5D mark II and after completing my grey scale test I found that the dynamic range of my camera was 11.

But would this stay the same if I increased the ISO from 100 to a higher setting maybe to 400 or 800?

I would go out and redo the test again and I plan to but it is raining very heavily today so I thought I would post on here and see what everyone else thinks of this question while I wait for a better day to go outside.

So can anyone tell me would the dynamic range change if I increased it?

If I had to guess I would say the lower the ISO is the higher DR and the higher the ISO is the lowers the DR?

Maybe? I'm just guessing and I'm sure you can all give me a much better answer to this question that me just guessing.

THANKS!
