How to correct blue-tinted photos?

Hello, Your device was presumably set to "tungsten light": artificial light emitted by incandescent lamps that produces an orange cast if there is no correction. It therefore corrects all shots by applying a blue filter. This is useful when photographing under artificial light but disastrous in natural light. It is very difficult to retouch this bluish cast afterward. So set your device to "natural light" when photographing in natural light, or, if you’re not sure, to "automatic white balance" (labeled AWB, Automatic White Balance, on many devices). Hoping to have thus "shed light on your lantern," sincerely.

Hello, do they look bluish when you look at them on the computer?

Hello, generally this is called white balance. This means that when you use your camera, you must first set the AWB mode or white balance, that is to say the lighting mode of your shots (automatic, sunny, shaded, tungsten, etc.). Sometimes it is necessary to use a small software correction for the white balance in order to reduce the dominant color in the photograph. See you later www.pmindeau.fr.gd

Indeed, it is indeed the white balance that is adjusted at the time of shooting; I think it’s worth referring to the manual (it can be useful sometimes!). As for editing already taken images, there are two free software programs that I use: IRFAN View, which is practical and lightweight, and The Gimp, which is very similar to Photoshop but also free and more complex. It requires some time to get used to, but eventually, one realizes that it allows for many actions.

Hello, I am familiar with the TZ6 because my wife has one, and in principle, the color rendering is very good in AWB (EAB on the TZ6). Three additional hypotheses, in addition to what has been said, which are very relevant: - Is this bluish tint visible on your camera screen or only on the prints? If it's only on the prints (which can happen), turn to the "printer." - You used your camera in "borderline" conditions of automatic white balance, which means that the auto correction was not perfect or complete. According to the manual, the EAB covers the range from 2700 to 8000°K, which can be a bit tight for low-energy lamps (2300°K) or for scenes with a lot of UV (mountains, altitude...) - You activated the fine white balance setting (page 72 of the manual)....it all depends on the shooting mode you were in...iA, Normal Image, MS1.... In any case, you can always calibrate the white balance as described on page 72 (last paragraph). To be continued...

But if you really care about these photos and want to correct them, Photoshop offers you the color balance and also the filters. You will achieve a result close to ideal. I tried it. If you took those photos in RAW format, the correction in Photoshop will be even easier. Best wishes for success in this endeavor!
