Sony DSR450 and EX3 - d log e Curve test?!

So, I am planning on using these two cameras in the near future but have no idea how i should go about doing camera tests with a digital camera...

 

I am familiar on doing tests for film but digital remains a mystery to me.

 

Here my goal:

 

- I know from film that the film stocks can (and should be) tested before any shoot to determine the perfect density levels as learn about the RGB response curve.

- I know that the digital cameras have strange color pattering in the highlights or shadows (because the RGB curves don't run parallel in the toe or shoulder of the curves)

 

As I would do in film:

 

- I want to test the digital cameras to find the perfect exposure range (dLogE curve?)

- Test the cameras (with CC filters) to correct the color shift

 

Question:

 

How do I do that? How can I get the dLogE curve out of the cameras to see how my tests affect the chip/camera characteristics?! I wan to see what happens to the curve if I throw an 81B or CC20 magenta filter upfront the lens...

 

Hope somebody can help me out...

Thanks!
