Color matching a7 ii

Hei, can you edit the comment and choose 'upload images' instead of 'upload files'? That way people can see the images without having to download them. Thanks!

Thank you so much! It is snowy and grey outside, so I made two shots from the staircase, trying to include yellow, red, blue, and shades of green. I hope the images provide the needed information. Please, write me if they do not.

Images: Fuji 400 H and Kodak Gold

Thanks!

The first image (Fuji 400H) has an excessive magenta cast. To correct this, increase the color phase by +2 levels and shift the color filter towards green by 0.5 stops.

These adjustments effectively neutralize the magenta cast by rotating the color balance clockwise. As a result, blues shift closer to teal, but the overall color rotation also makes the reds appear too pink. To counteract this, add more green to restore balance.

The second image (Kodak Gold) has a strong olive-yellow tint when it should lean more towards an amber-orange tone. To correct this, increase the color phase by +1 and shift it towards magenta by either 0.5 or 1 stop. Additionally, raise the Kelvin temperature by +200. These changes will push colors toward amber, correcting reds that appear overly pink and yellows that are too green.

So you can better understand what the Color Phase does, I prepared 3 reference images:

Color Phase 0

Color Phase +7 (rotates colors clockwise)

Color Phase -7 (rotates colors counter clockwise)

After reviewing your references, I found that the A7II's color science resembles that of the A7III, which leans heavily toward yellow and magenta tones. As a result, most film simulations would benefit from a Color Phase increase of +1 or +2, along with a shift towards green in the color filter.

I asked you to capture both Fuji 400H and Kodak Gold to observe how your camera renders colors at both the cool and warm ends of the spectrum. These adjustments serve as a reliable benchmark for fine-tuning film simulations. Now, you can apply them to refine your results accordingly.
