colour balance with masks

Jay Pegg
I've done some research and cannot find a way to change the colour balance with an adjustment mask. The colour editor will change the saturation, etc but I can't get it to "warm-up" a masked blue/grey sky. cheers, jp

    The color balance editor does not work with adjustment layers, hopefully that will be a feature in the next major release.

    It does indeed work, but only with the Advanced tab, not the basic tab.

    Let me rephrase then, white balance doesn't work as an adjustment layer. If this is not what the original intended question was then I apologize, I misunderstood.

    That is correct. Capture One cannot apply two separate white balances to the same image. The file needs one white balance value to base all other color adjustments upon.
    Please use the Color Editor to change hue in the mask.

    Thanks Guys. Just to make sure I have this correctly. It is not possible to change the colour balance with an adjustment mask. Right? I could be wrong, Drew, but using the hue adjustment gives me different shades of grey/blue. It does not "warm-up" the sky. Cheers, jp

    That is correct. One file = One White Balance.
    The hue rotation can give you a little more Magenta and thus make the selected color feel a bit warmer.

    Drew, do you see C1 allowing us to apply white balance settings using the adjustment brush in the near future (perhaps C1 😎?

    White Balance is a tricky one to separate... it's like suggesting you be allowed to use two color spaces.
    Since so much depends on White Balance, trying to integrate more than one into a single file simply doesn't make sense.

    Perhaps we could suggest a tool to the developers that puts something like a warming or cooling filter over the masked area but again, some of that can be done in Advanced Color Editor.

    Perhaps the tool would have controls that mimic white balance controls but in the program calculations itself is basically adding a color filter tailored to the users input. This might be how ACR/LR does it.

    The Colour Balance tool would help Drew! I do a lot of stuff under mixed lighting (interiors with daylight through windows AND tungsten lighting) the ability (easily and selectively) to apply a colour change would be fantastic!

    There are applictions out there that address the requirements of localised white balance adjustment and can do it successfully - though don't ask me how at a technical level!

    I could see something like a multi-image merge for example as one might achieve in a graphics editing system like Photoshop whereby you could create multiple version of a RAW image with different WB values and blend them.

    For this to be possible at a "local adjustment" level may require a similar sort of psuedo 'layer' approach. That might be a bit 'coarse' for C1 concepts. I would not want that to be seen as a criticism - I like what I can get out of the C1 import for the bulk of my images. If, for a few, I need something different and maybe not as polished, then so be it.

    I am not disposed to the idea of touting the names of other products in vendor forums - unless asked of course. However there is one product that looks quite good (I did not buy - I don't have enough need) for local WB adjustments that sets out to be an smart HDR oriented application.

    My pre-C1 favourite application is about to re-appear (hopefully) as an Open Source development. Great results from an incredibly broad and flexible local adjustment feature set - but you have to do the work to get the best out of it. Fine for those special images, a bit more of a challenge for 'bulk' wher C1 is, I find, very strong for getting results at the image by image level of interpretation with minimal, if any, intervention from me.

    (However it does offer local WB adjustment. For selected colours and luminance too ....)

    It isn't that important because I can get a localised colour balance in PS. One just gets lazy about flicking the image between applications. Human nature I guess - a bit like it's a pain emptying the dishwasher. jp

    Or you could use the Colour Editor Advanced mode in C1 I would think. It may need a little experimentation to get it about right to start with but you should be able to work out some values that you can then use, perhaps as presets, in the future.

    I'l just like to say that having a WB local adjustment tool would be at the top of my "most requested" features I wish C1 would implement.

    I'd like to see this as well. There are so many occasions where this would be helpful.
