There’s a bit of stigma surrounding so-called “teal and orange” colour grades thanks to Hollywood, but I’ve nearly always preferred the colour contrast on offer thanks to blue casts in the shadows to a “correction”.
And if I’m drawing attention to the bridge with colour, I don’t want too much information in the sky competing with it.
Kinda challenging to decide how / where to take this image. I ended up trying to contrast the industrial character of the bridge with the natural green nature of the surroundings. I probably went too far. The bridge and its treatment is cold, bluish, noisy and high contrast. The trees (and even sky) are warmer and more saturated. The cloudy sky seems to be a bridge between the two worlds, no pun intended.
My play in GIMP. I have tried to bring out the internal structure of the bridge by changing the contrast and brightness in the darkest areas. Slight increase of saturation in low contrast parts to attempt to show the colours in the concrete without the sky becoming too blue. Cropped, but leaving some of the trees to frame the picture.
