Has anyone see a color cast like this? The sky looks close-ish to what I remember, but the lights on the right are causing a crazy green color cast I've never seen before.

Sorry, we have dark skies here ... not as dark as I'd like because of light pollution from nearby urban stuff.

Colour cast here is non-existent. Campaign for your local government people too shut the lights off and save energy.

Several kinds of street lights can produce green or orange casts. You may or may not notice the cast when you're there, but the camera will capture it as it is.

I'm guessing you used auto white balance.

You have a wide variety of light sources with several different color temperatures and light characteristics.  Light sources with discontinuous spectrums are a particular problem.

As you can only select one color temperature, only one of the sources will record correctly.

 

When viewing the scene yourself, this is frequently not noticeable.

 

I looks to me like you did about as well as possible.

Mixed lighting.

 

The camera never lies.

 

Your eyes do ....... the brain selectively auto white balances to adjust some colours to what it expects from past experience to see. 

 

Nothing you can do about it ..... just pick the balance that gives you the best final image that pleases you ......

Cameras do lie actually, a lot. I do usually leave the camera in auto white balance unless I'm in my studio, this image is tweaked to about 3,800k in Lightroom.The only lights I've run across before this that can give a green color cast are fluorescents, but really only on film. Until recently, LA's street lights were strictly sodium, so they gave a sickly yellow light, which I would usually tweak to a warmer orange tone.

 

I guess my question should have been, "What lights can throw that much green into a scene?". I should have gelled them

 

 

BTW, there's no correcting it out without masking the area and doing some serious color correction in Photoshop, which creates a lot of noise (because the red channel is so weak in that area. *sigh*

Forgive my rant about urban lighting, but looking at the tops of the tall buildings in the background makes everything look insane.

 

Further scrutiny of your pic shows the prime suspect to be the lamp in the top right hand corner. It is definitely emitting a strong green cast.

 

Some people might suggest solutions to be a catapult or an air rifle, although in LA an assault rifle might be more appropriate. I couldn't possibly comment.

Yeah for a city that's prone to brown-outs, there sure is a lot of lights on at night. Flying into LAX at night is a surreal experience, just a field of lights stretching off towards the horizon. 

 

The city's been on a tear lately, replacing the sodium lights with more efficient LED's but like all things American, the wealthier neighbourhoods get priority. Between the smog hanging in the air and the light pollution, stars don't make many appearances in photos.

Actually - not having any preconception about what the scene should look like- I quite like the colouring in this shot. I do not see any reason to go photoshopping, it is fine as it is.

I agree.

 

I like the overall look of this too... in fact I REALLY like the look of it. I would leave it exactly as it is. Printed well, large, with a wide white passe-partout, it would be very striking image. The only bit of Photoshop I would perhaps do would be to remove the horizontal wire across the middle. The colour cast isn't an issue, it's such a dramatic, clean, green!

 

 

(what is the white line in the sky above the tree on the left - it doesn't look like a vapour trail..?)

My experience with digital and all sorts of lighting indicates a strong possibility of the green lights and their color cast being sodium vapor lights as someone previously suggested. Not all of these are of the same spectrum and resulting color can vary.

 

I too with regards to this inage like the green cast.

My guess is mercury vapor lighting (light at top right in pic), common for outdoor sports arenas, industrial areas, etc, despite the fact that it is apparently being phased out, if not already banned.   More here....

I appreciate that comment Jaapv, thank you.

Thanks Bill, that's very kind of you.

 

All I've done to this image is a quick white balance and contrast curve. The initial raw file was much more flat, but of course when you increase the contrast and deepen the shadows, the green becomes very present. I probably wouldn't remove the power line going across the road, I don't find it very distracting, but I probably will remove the bright white wire on the upper right. The line on the left is a helicopter (which I'll also remove). It's nearly impossible to take a photo at night in LA without either a helicopter of jetliner leaving a trail through your image. So obnoxious.

Looking at it again, I think you are right, the power cable isn't as distracting as I first thought... and it gives another horizontal to balance all the strong verticals while supporting the horizontal of the buildings in the mid ground. 

 

Love to see the version with the helicopter and bright wire removed... would you mind posting it when done?

 

thanks

FWIW, The orange cast in the far distance (city) and on the loading dock at left is Sodium vapor, the foreground, Mercury vapor. Looks like HID a bit in the middle ground. I think what makes this picture work as well as it does, is in fact the different colored lighting, which end up defining separate areas, adding to a sense of depth and distance. Really, not a bad balance between the two major color sources. Love the balance of the green trees on right and the sodium lit loading dock on left. Wouldn't work as well without those two elements.

It's been put on the back burner for the moment, prepping a shoot right now, but when I get a chance I'll do my edits and post my results.

 

Thanks everyone, for the positive and constructive feedback!
