I'm a little unclear what you're asking, but if you literally want to measure the color temperature of the light from the setting sun, you can take a photograph of the setting sun in raw mode, making sure not to overexpose the disk of the sun. Then, in your processing software, you can set the white balance by clicking the eyedropper on the disk of the sun. ...


But there is nothing objective about perception. If the goal is to attempt to reproduce the perception, the closest will be to set the white balance from a grey card which is not directly lit with the Sun.


As you say, white balance is a subjective game. The only way to do this in anyway objectively would be to process your photos in conditions where all the factors affecting subjectivity, i.e. the colour temperature of the ambient light, is the same as when the photo was shot. In my Canon 5D Mk III, for example, this could be done as follows: Shoot the ...


When it comes to the sun, objectivity is harder than that. Color of the setting sun is changing while it's descending - and white balance basically means that you choose the light of the sun as white point. It differs minute-to-minute in last stages of sunset, but overall - you should decrease color temperature if you want to set white balance correctly ...


Different sensors do have (beside all the other different properties) also a different color depth. Meaning that one sensor most likely can pick up more colors than the other. Also two identical sensors could potentially see colors slightly different, thats why each decent camera has a calibration setting to compensate. Better cameras are pre-calibrated and ...


Both white balances were set to a temp of 4150 and tint of +14 in Lightroom Same color temperature and tint does not mean the same white balance on two different cameras, even if the profile is set to Adobe Standard for both, and same process is used. The reason for that is that color temperature and tint depend on the profile, and profiles for ...


There is no easy answer. If you were viewing by unnaturally blue light, you might get used to it and everything seems normal after a while. but, you could not tell the difference between a blue object and a grey object, or differences in blue hue between them. Now consider that other colors have some blue component... the information is lacking, and your ...


This one is complicated. The natural response of your eye in well-lit conditions is known as the photopic response. When the light goes down a bit, your eye switches to Mesopic vision, essentially generating and using a good number of rods to supplement the cones. Your cones have very good color sensitivity, but are inefficient and bad in the dark. ...
