| p.1 #3 · Hi : ) !!! - Unifying colors? |
Often the differences aren't so much color but contrast due to more or less internal flare and reflection of light (with color tint) off the sensor >back element of the lens > back to sensor when wide apertures are used in bright light. Even profiling each lens separately wouldn't eliminate variables like that which is why as howardm4 said it's a waste of time, practically speaking.
In PP the place where you'd want to adjust color selectively is the camera profile tab in ACR. That's where you'd apply a custom camera profile if you make one by shooting a color chart.
As an experiment to see how it works just shoot a color chart with "neutral" style set in camera then select the different styles from the menu on the camera profile tab while viewing it. You will see the colors shift around but the neutral patches on the target and scene content will not change. In addition to the styles the color can be selectively tweeked with the sliders without an overall temp/tint shift in the neutral content. Once you find a look you like save it as a preset and all the other files opening in ACR will be display with it until you change it. Thus if you are seeing consistent shifts between lenses you could create a "custom recipe" here for each lens then apply it to all the other files
In situations where you have consistent lighting, such as studio flash with the same modifers all the time profiling each lens might be worth the effort, but even then unless doing something like shooting for a clothing catalog where color match to garment is critical in the photos or reproducing artwork exact match isn't usually needed because the process of seeing color by eye is so adaptive.
In practical terms a simpler way to eliminate lens-to-lens variation in color in more general shooting would be to use a zoom lens instead.
What I do is shoot from a baseline of Neutral style in camera, then using the ACR camera profile screen find what looks best for that subject. That varies with subject. My goal isn't a technical match of color lens-to-lens or photo, but max. emotional impact from what color adds to the mood of the photo and reaction of the viewer. Isn't that the real goal of the exercise?
