>>Hello CD and congrats on your recent awards.

Thanks, I'm in Tuscany (for Tuscany Photographic Workshops etc...) 
right now, which for me is the the biggest award of all.

>>So can you offer any tips on neutralizing my black point?

Since we haven't implemented a 20% luminance version of our 100% 
luminance White Balance function, we don't really offer a tool for 
that. You can use the colorimeter window and adjust from the values 
that lists from near black patches defined there, though thats a bit 
less convenient...

>>And why don't the manufactures provide black point adjustment any 
more?

Most don't even provide white point adjustment anymore, its just the 
way the LCD market is going...

Hello CD and congrats on your recent awards.

So can you offer any tips on neutralizing my black point?

And why don't the manufactures provide black point adjustment any more?

Thanks for the help!
