I've already had to dial back the turquoise, since, straight out of camera, it almost blew out Adobe RGB, let alone sRGB.
Just corrected the slight green colour cast and saved it again, using a different conversion setting. How does it look now? Aside from the slight colour correction and cloning out dust, etc., I haven't actually done anything to the ProPhoto RGB file since I first posted this image - the only thing I've changed is conversion settings to change it to sRGB. So the problem seems to be entirely in the conversion settings, not the original edit...
Just saved it again to fix a colour cast, clone out some dust and apply a slightly different conversion method. Does it still work properly?
If someone's running a completely non-colour-managed browser on a wide-gamut monitor, I doubt there's much I can do to make the image look good there.
I think it's really a tough edit because of the original contrast, SB. It seems that no matter what, one adjustment significantly affects another, like the blues in the water and mountain and the blue in the asphalt on the road. I understand that you're attempting to get a global edit to deal with the entire image, but I don't know if it's possible, embedded profile, monitor and browser issues aside.
As we both know, an image like this is often tackled with HDR, but in this one, it would be just ugly eye candy using HDR rendering algorythms.
In tough images like this where the contrast is just "spikey" if the image is worth it to me and I really care about it, I select several parts or "components" of the image and make layers out of them and edit each individually, mostly for color, clarity, shadow/highlight and sharpness. Once refined, I begin by editing each area by doing a 3 layer approach in new images by selecting the area just edited and making a new layer via copy, then going back to the background, select the inverse making a new layer via layer copy, then I make final adjustments and flatten the 3 layer sandwich and move on to the next major component adjustment. I would probably have several independent layers: Sky, water, roadside right, road, roadside left, roadside left upper, and mountains. Each layer would be individually edited for the above mentioned and would be feathered in via layer coppies. An edit like that would probably take me 2-3 maybe four hours, but each element would be fully controlled and not influenced by any other. In most cases, I make layer masks and or paint the adjusted layers in.
You've just about got it, but given the complexity of the interactions of the shadows and highlights and nearly clipped areas of several colors I'm just not sure you can do more other than getting into the kind of edit I discuss above. Of course stylistic preferences play a big role as well. If you want blocked up shadow areas such as in the edge of the evergreens, and you want blue for the color of asphalt, and you don't mind if you've lost much of the detail in the grasses on the right side of the road, then overall if it's the effect you're going for, then you have it.
I do think it's a very cool capture and like I say, editing-wise, you've got a tiger by the tail.
