What's it called when white objects or white backgrounds become blue in photographs?

This is called a color cast. As others have said, it is a result of an incorrect white-balance. Your camera is assuming that light is of a different color than it is and is compensating for that, ...

Why did my developed photos come back blue outdoors (and fine indoors)?

It looks like the laboratory messed things up: the film you used is a daylight color negative film. Which means that basically, without (extra*) correction, the daylight images should have been ok, ...

What's it called when white objects or white backgrounds become blue in photographs?

Your camera, for whatever reason, is setting the color temperature and white balance at different points for the two images. That gives it what we often call a color cast, *tint*, or hue which simply ...

Vintage vs modern B&W photography techniques differ in color luminance - what's going on here?

Just to expand on Matt's answer a bit. Most B&W films used during the first half of the 20th century were not panchromatic. They were much more sensitive to the energy in blue light than the ...

Vintage vs modern B&W photography techniques differ in color luminance - what's going on here?

Photo films and digital sensors do not record colors exactly as seen by our eye / brain vision system. Initially, photo films were only sensitive to the violet and blue region of the visual spectrum....

Vintage vs modern B&W photography techniques differ in color luminance - what's going on here?

Are any of these in the ballpark? The last one: "imperfect chemical film response". Most black and white processes are not "panchromatic". That is, it does not respond the same way across the whole ...

What's it called when white objects or white backgrounds become blue in photographs?

This happens when your camera/phone/whatever evaluates the light badly and sets an incorrect white balance. It can be easily fixed in post-process in pretty much any editor. Also it's pretty common ...

Why is there blue 1" edges on developed 35mm film?

This is definitely edge-fogged film. We can’t say if the film was light-struck due to improper camera loading /unloading or camera light-leak or if the film was mishandled at the processing lab. All ...

How did the designer achieve this Blue tint effect?

It looks like he created a blue layer and gave it opacity, after converting the picture layer to black and white. So, make a new layer over your image, and flood-fill with blue. Then, set opacity %. ...

Why do some star trails appear blue?

Some stars are showing up as blue because some (actually, a lot of) stars are blue. You can: adjust white balance (making more stars appear orange instead) reduce color saturation (this could make ...

Counteract strong blue light emission from a cheap LED

You appear to have actually two [& a half] separate issues caused by the same thing. Firstly the blue spots - which, btw, won't do you any harm so long as you don't stare directly into the light ...

Why do some star trails appear blue?

To expand on the reference to white balancing in @szulat's answer: If you don't explicitly white balance the image to a reference temperature, arbitrary light sources in the scene may end up being the ...

Why did my developed photos come back blue outdoors (and fine indoors)?

You mentioned in a comment on another answer that outdoor photos of overcast scenes also look okay. If only the bright outdoor scenes have weird color balance, I suspect those frames were overexposed. ...

Why did my developed photos come back blue outdoors (and fine indoors)?

The problem is the fault of the photofinisher who developed and then printed the film. The film is developed up to a negative image. This negative image consists of dyes that are laid down in ...

There is a distinct blue-green tint in the pickguard in A, so you can adjust the white balance in A & B by making that neutral. Another place to check is the teeth. D isn't OK, it's quite reddish ...

concert lighting difficulty with blue lighting - how to fix?

If you use Lightroom for RAW development you could look at the Profile in the Basic tab. In my experience this impacts the way colours are rendered significantly.

concert lighting difficulty with blue lighting - how to fix?

Colored lighting produces single-channel blowouts that can't be fixed in post. The only real solution is to underexpose. I aim for a couple of stops underexposure in most concert situations. For every ...

Why did my developed photos come back blue outdoors (and fine indoors)?

Alternate theory: I have seen this type of colour shift in C-41 film that is drastically underexposed. (like 3-4 stops) It really looks like something is up with your shutter, based on the reference ...

Can anyone reproduce the white/gold vs. blue/black dress's binary perception effect with a totally different subject?

As Count Iblis explained, people likely have a pretty good idea of how that dress should look. The image is ambiguous, but each option cancels the other out - the dress can't be kinda both. Similar to ...

What's the reason for this exceedingly blue reflection from buildings in this image?

Another factor that doesn't seem to have been touched on directly at least is your metering mode. I suspect you are using a matrix/evaluative metering mode (naming varies by manufacturer) that ...
