Photoshop: Color temperature (and tint) adjustment layer

I would like to see a simple color temperature adjustment layer in photoshop, 2 sliders, one for kelvin, one for tint, and a neutral color picker.

While I do know that all those adjustments can be done by other adjustment layers, it would still help (me) to keep those numbers in the same realm as they are in ACR (I like the ACR sliders, and like to see them in PS also).

ideally, the adjustment would be aware of the native color temp of the layers below (via exif or calculation).

this would be helpful for photographers who know their color temperatures, and need to adjust (especially mixed light situations) via said settings and prefer "real world" measurements instead of relative numbers.

if that isn't a possibility, I would like to see at least a new info palette option for color readouts: kelvin and tint and brightness (making it a sibling of the Lab readout).

I posted this request also at http://forums.adobe.com/thread/781779... but it didn't got much traction there.

I'd like to see it, too. I like using it in Camera raw, and it'd make even more sense in Photoshop.

ME TOO, would be awesome, now if I make a tweak I have to do it in Camera raw and than bring in over the top as a hard layer where everything underneath that is a layer is no longer accessible for changes. CS6 PLEASE!

Chris or Jeffrey: any way this could be considered for CS6?

Bear in mind that without Photoshop knowing what the original white point is, there isn't any way to have meaningful absolute corrections, e.g. to 6500K white point. That's why you're able to change to 6500K white point in ACR, because it's able to read your original white point from the RAW file.

But, to your larger point, that it would be super handy to have a simple slider for correction of blue-orange and pink-green axii, yes, that would be super handy.

Perhaps that could be incorporated into or replace the Photo Filter adjustment layer, since that's all I use if for anyway. I really doubt that there are that many people out there who need to approximate LEE Warming Filter 85, specifically.

ACR also has access to the linear (gamma 1.0) data before any sort of tone curve is applied -- so it can do white point correction much more accurately.

Yes, a correction in Photoshop would have to be more of a blue-yellow / green-magenta correction. (which you can do pretty well with levels, BTW)

Oh, and people do need color filter adjustments - which is why that adjustment exists (they had all sorts of inaccurate workarounds before it was added). It's not always the Wratten (http://en.wikipedia.org/wiki/Wratten_...) filters that they're after.

Since nearly all PS files are gamma corrected and as Chris points out, a WB option as we see in LR and ACR are far more effective on linear encoded data, the question becomes, in Photoshop do we really need what we think is WB or simply a way to alter yellow-blue or magenta-green? Don’t we already have that available? Is it the use of some scale (in CCT Kelvin) users are asking for? Or, do we want these gamma corrected images to somehow be “converted” to a linear gamma such they could be altered differently than what we have today and on an adjustment layer?

Could one open such images in ACR, apply the WB and just save that as a smart object? Would such images need to be converted to a Linear DNG in order for ACR to have full access to WB controls?

I switched to CS5 from Elements 6, and was surprised to see several tools I relied on absent in the full version. Two of those tools were the WB/tint sliders. So in response to the people scrutinizing the logistics of your request, Adobe Engineers have already worked around those limitations (or embraced them) by creating the white balance/tint option in Elements several years ago!

Elements just shows you simplified versions of the tools in Photoshop. So all of it is there in Photoshop.

You can handle white balance in levels or curves (see the white, black, and gray eyedroppers).

Clicking to set white points is really fussy compared to the desired functionality, a blue-orange correction slider and a green-pink correction slider. We're not saying it's impossible to do this work in Photoshop, just that we'd like it to be as easy as in Camera Raw or Elements.
