OK I am talking part rubbish here ....my memory needed sorting!!!


I have just revisited the 3 generation raw files (D70/D200/Fuji)

The image below shows the difference.

On the left the 'as shot' settings
D70 2000/-85,
D200 2000/-64,
Fuji 2000/-77

Alongside the D200 and the Fuji are their default files adjusted to -85.

In doing this I have rejogged my memory.

Firstly, there is less difference between the D70 and D200 as shot colours than I remembered. The Fuji is clearly a different glass source!

But the reason why I adjusted the D200 back to -85 was NOT to get it closer to the D70 but to null out some of the magenta in the tint. I found the D200 images slighty (doesn't show on screen) more red/magenta

When you try to play with residual colours I found Magenta a messy hue to have present...it makes things greeny when you do any channel mixing (without a lot of manual intervention)

I shifted the hue back to -85 on the D200 because it gave a purer yellow overall cast which was easier to work with ...especially when flipping to the complimentary colour blue! There were less spurious colours creeping in.


My memory was correct with regard to WHAT I did...not WHY!!!!

Its interesting that ACR is limited to 2000 temperature when you say Bibble allowed less. It seems to me THAT is what is required to null out residual colour on the files...be that magenta or yellow. Of course full or partial desaturation can do that. But having SOME colour there does make creative tinting easer.

How do the D1X raws compare to the D200 and what numbers?


Jonathan
What are you using for p[rocessing the D70 IR shots? If ACR, are the numbers the same 2000/-85?
