I recieved my samples of all the Carada materials and the grey is too dark for my tastes overall, but like the darker darks it gives. I am still waiting on the elite sample of Elite Cinegrey but was wondering if the cinegrey is a little lighter in color than the carada. I found gain numbers for each and those would imply the elite is lighter. Does anyone have color, munsell shades or any other info for these two greys?

Thanks!

What are the gain values listed and just a curiosity question... why do you correlate gain with how light or dark a screen is? Or are you talking about how bright the projected image is?

 

[nawagner]

Carada Grey - 0.8
Elite Cinegrey - 1.0

I would be talking about the image brightness, but would also assume that the overall color would have an effect on brightness, given darker color would give darker image and lower gain by intuition. Am I wrong on this thought?

Carada High Contrast Gray

RGB 167 165 162
CIE Lab 67.9 0.07 1.75
xyY 0.317 0.333 37.8

That makes it about an N7.

Elite CineGrey

RGB 195 197 198
CIE Lab 79.5 -0.45 -0.88
xyY 0.310 0.327 55.76

That makes the Elite a N8.

Gain isn't a function of screen material tint/shade but is directly related to brightness, so I can see how you might get that confused. There are some darker gray screens with a gain over 1.0 but that doesn't mean the screen material is lighter than a 1.0 white screen, does that make sense?

I'm pretty sure we do have color readings on these and where they fall in relation to the Munsell rating system... let me look around.

Mech beat me to it!

Not only is the Elite an N8 and lighter, it is also D65 neutral.

So as I see the numbers the Elite will be a lighter material color, and a brighter image. Lighter material due to the color and brighter image due to the gain. Correct?

What does D65 neutral mean?

These graphs are great, and am learning more about it slowly. Is there somewhere that has a tutorial on how to read and what they mean?

I am assuming that the color balance means they will show greens about the same, but the blues and reds will be pushed in opposite directions on these two screens?

Lastly, (for now!) if I want a brighter image but still want some deeper blacks the elite would be the best option based on these numbers?

When testing the carada material the cinama white washed out too much with ambient light, but the grey was too dark, so I'm looking for an in-between!

Mech, can you post color charts on the cinewhite and cinema white?

Thanks to both of you guys for your help!!

Here are a couple of good links to get you going as far as an intro to what all this stuff means...

Yes the Elite is a lighter gray. I was not impressed with Carada's High Contrast Gray. Carada does have an excellent white material in their Brilliant White though.

I am assuming that the color balance means they will show greens about the same, but the blues and reds will be pushed in opposite directions on these two screens?

No. The Carada is a darker screen material so the greens will be darker. The RGB Color balance chart is specific for the material being measured only. :T

Lastly, (for now!) if I want a brighter image but still want some deeper blacks the elite would be the best option based on these numbers?

It's what I use. :bigsmile:

Mech, can you post color charts on the cinewhite and cinema white?

Yep. But it was done back in the day of BabelColor so the chart's a bit different.

RGB is 232 236 236 and the color temp would be 6619. It's what we would call a close neutral because it is a white screen and white screens are very forgiving. I'd assume that Elite let it push a bit more blue because most folks perception of white is actually a bluish white.
