camera color mode and working color space?

[krusty4president]

Hi.
I am a bit confused (like almost everyone with color management questions) on how to choose working color space.

I have a Nikon D80 and am using color mode IIIa on the KenRockwell recommendation. Thats a sRGB camera color space. I am shooting in raw though. And I have a calibrated EIZO Flexscan L767

When I capture and work with the pictures in Lightroom they are getting the prophoto RGB working profile, right? Is there any problems there if I use the sRGB color mode IIIa then? Or is it just the way to go?

Then when I have edited it in Lightroom I want to soft proof it in photoshop with the printer profile the lab provided me with. What are the settings then for the external editor in Lifghtroom export prefs? I usually use TIFF 16-bit but the images get huuuge?
And what color profile is best here? I can choose between sRGB. Prophoto RGB and Adobe RGB?

Then when I want to continue editing in Lightroom and I have made changes to it in Photoshop, maybe filters and stuff, which format is bet to save iut in Photoshop? TIFF 16-bit again or...

You didn't like the answer I gave you about Ken and the LR color management on that other forum?

And stop listening to Ken if you're using a professional product like Lightroom!

I don`t recommend III color mode for you d80 camera, I recommend you II color mode, it is more neutral.
The using of this modes it is only justified if you use capture nx for converting your raw. With this program you can change between color modes like in your camera.
If you are using LR, use II color mode and calibrate your camera.
