'Pigment' Free Gray- Initial Development and Testing

[mechman]

This is a comparison of Luminous White/Dice 4:1 and True Value Winter Mountain. The LW/Dice is on the left in all the shots.

The room is almost completely dark for all shots. I had the back cans dimmed to about 10% - just barely on.

Some Data

I was originally planning on posting images of the screen captures from HCFR here. That will have to wait until Smokey Joe gives me the A-OK!

Conclusions

This one was my favorite. I know it's not absolutely dead on neutral but to me it had great whites while maintaining excellent blacks. And it appears to have a viewing cone in the 120 degree range.

What you should really be noticing here is that Dice is a darker mix and yet has whiter whites than Gray Screen. Such as here:



If you look at the sky as well you'll notice that Gray Screen does a much better job at colors than my FG screen in the background. And Dice does better than both!

As for blacks, Dice does it as well if not better than the others. It's hard to get a good picture comparing blacks but this one shows that they appear to be equal. They are close but there is an edge to Dice.



Off axis shot



Skin tones and detail go to Dice:

What I tried to show with this shot was that there was more detail and, as much as I hate using this word, 'pop' in the dice panel. Once everything gets compressed into a jpg though...



This ~15degree off-axis shot shows the better blacks and better colors of Dice!

The Ant Bully



These were for showing of the afore mentioned attributes! Plus I loved Clarence's shot of that wasp and had to see how it would look here!

This will have a UPW 3:1 panel in it as well as a Luminous White 3:1. For some reason Dice did not mix well with UPW. You can see for yourself when I get the data up here. I thought it would as both LW and UPW are pretty similar...

There are a few LOTR shots with all three panels in them. The LW3:1 would be on the left throughout, the UPW3:1 to the right when there are three panels, and the TV Winter Mountain would be the middle panel when there are three and on the right otherwise.
