#12Y+XNiteCC2 EIR colors


Recommended Posts

These are recent shots with Sony a7R/ Nikkor 50mm/f1.8 Ai and #12 Y + XNite CC2 stack. Again, using the NS profile injected into the converted DNG file. The original NS workflow recommends shooting with Daylight WB, but I prefer CWB on a gray target. When importing into PS Camera Raw, I adjust the Temp and Tint sliders.

 

I did try substituting the CC2 with a KG3, but ended up with way too much purple for my liking.

Garry, Very nice photos.

CC1 = BG38

CC2 = KG1 (a weaker version of KG3)

So stacking CC2 + KG3 is the same as stacking KG1 + KG3 (which is the black line on the last graph below).

Thanks Colin. I included the first one, just to show the EIR color switches (ie. red cars and sign switch to green, taillights turn yellow, etc.).

 

Much appreciated Andy !

 

Thanks for graphs Steve. KG* filters are a very versatile range filters, for sure. Good to know about the KG1, in case I break my CC2. I'll give the KG3 another try over the summer.

Interesting colors.

After looking at these and thinking about the GRB3 images, I would say my Chinese GRB3 at 2mm is closer to KG1 than KG3. Just about in the middle.

I will hopefully have time to run it on my spectrometer soon.

The greens are unexpected in the first frame--I rarely see such a color in this kind of image, except perhaps from red LEDs. Otherwise, the color looks very film-like.

Thanks Clarke,

The NS profile, does a good job of re-creating the color switches related to aerochrome processing.
