false color on night shots

There's a tendency for much of my night long exposures to turn orange like this. I'm using daylight WB. Trying to correct it in post process makes the entire image carry a blue cast. Any tips?

Try the lightbulb wb, and if that doesn't succeed set a custom one.

Sodium vapor HIDs have no blue or green and way too much yellow. If other lighting is present present use WB to cancel out most of the yellow and some of the red. Go for longer exposures with the reduced available usable white light. Shot in RAW mode and you may have enough WB f/stop range to daily them in. Canon Digital Pro post processing is best to use for this if you shooting with a Canon.

shoot in RAW color correct in post.

literally a 2 second edit. I could make it look better if I spent a few more minutes on it.

1.


I figured it out. My problem was using a RAW plug-in to play it back. I just went through the trouble of installing View NX and the edit result is much better.

That was achieve by opening the photo in Adobe Camera Raw (ACR)
I never brought the image into photoshop.

I do the vast majority of my processing in ACR. very little of my editing is done in photoshop. ACR is extremely powerful especially if you get things right in the camera. I HATE being tied to a computer but very much enjoy the process and craft of photography so I chose to spend my time behind the camera instead of in front of the computer fixing images in post.


Deuterium, as a side, your image is a bit hot. The highlights are really bright (actually, they're blown out) making the rest of the image hard to manage. I find with night shots its usually better to be underexposed a bit rather than overexposed. I shoot night stuff with the consideration that its going to be tweaked a bit in post. With that in mind I try to manage my highlights and not blow them out. I can add fill light to brighten up the darks but once the highlights are blown they're impossible to reel back. Granted night stuff is tricky to shoot because of the huge contrast in LV.

Should I do a spot metering on the brightest spot and do a +1 EV when multiple shot for later adjustment isn't possible?

Hadn't used ARC, the Canon DP always did a nice job. I don't playing endlessly with an edit. Better to set up the exposure right in the first place. I use manual settings a lot for shots like this.

If it's a high end cam it will have many exposure zones, use them! Understanding the technology in your specific cam and how it works will help you to get the most out of it. Digital cams metering zones are much more sophisticated than a film cam, but only if you use them correctly.

Spot metering is useful if that object is the focal point of the photo.
Play with the exposure weighing settings to see what works best for your cam, then dail in the exposure.

I have three options:
Spot, center-weighed and evaluative.

If I choose "spot AF", I can choose where the intended focus aim is and the AE metering follows it too. In evaluative, the bias goes towards automatically chosen AF points. So, AE would bias towards correct exposure in the general direction to the lower right in this example:


The center weighed seems to be set in stone on "center of frame" bias and evaluative also relies on AF logic.

It locks out the ability to aim metering once I throw it in manual-focus. It's a nice hardware with trash firmware.

I probably go full manual. I get a AF lock on the brightest and dimmer areas you want to show, then play shutter speed, ISO settings, etc and dial it in. Shooting full manual is fun once you get use to it. The cam is still doing it's exposure zone thing so mind those settings too.

After the shot use the histogram to see if you're blowing it out or grossly under exposing it. It's more accurate than what you can see on the screen.

Digital are much more complex, but can grab images film shooting only dream about. The more you understand the technology of your cam, the more you can Keepers you can grab. Been 5 years since I shot with a good cam, lol. Anything's better than my damn Android... still have my 20D, but it truly pains me to shoot with it.
