Canon color shift?? (Need help)

[shotbyjosiah]

I have the Canon r6 mark ii with the 24-105mm f 4-7.1 kit lens and I've noticed a bit of a color shift when I take pictures. The colors will get duller or more vibrant, or sometimes I think a bit of different colors will show up. I've been told that's normal and it's an ISO thing. I've been told the higher the ISO is, the more of a color shift that happens. Can anyone confirm if it's true or what's happening?

We need a whole lot more information. Are you saving camera JPEGs or raw files, etc. Consider uploading an example. One possible reason for what you describe is white balance -- how do you have it set?

Im shooting in raw and I usually set my white balance according to my situation so if it's sunny then I set it as sunny and sometimes I set it custom. And I don't have any example unfortunately. Ive just been told it's possibility an iso thing. Sorry for minimal information I don't know what's happening so I don't have too much info.

If you're saving and processing raw files then white balance doesn't matter -- set that in post. And ISO is unlikely the culprit as well. What software are you using to process the raw files? And are you using extremely high ISO values? Your camera has a FF sensor and should allow you to work at very high ISOs. I shot a quick sample for you using an M 4/3 sensor camera. One photo at ISO 200 (base for the camera) and another at ISO 6400. I processed both raw files identically except for noise filtering -- none for the ISO 200 shot and appropriate noise filtering for the ISO 6400 shot. Pretty hard to see much difference and your larger sensor should let you do better.

Using extreme ISO will reduce dynamic range & this can affect colours, but I wouldn't expect it to be noticeable at everyday ISO levels.
It is possible that one of the channels is getting clipped if the exposures are a little high. I've had this happen when shooting infra red, while overall exposure looked quite far in. Checking the 3 colour version of the histograms can rule this possibility out.

It’s possible that what you’re experiencing could be related to the way color shifts occur at different ISO levels, but there are a few things to consider.

As you increase the ISO, the camera amplifies the signal from the sensor to capture more light. This amplification can introduce noise or color shifts, especially in lower-quality or high ISO settings. While it's true that color accuracy can degrade as ISO increases (particularly if you're shooting in lower light or with higher ISOs), the degree of shift can depend on several factors, such as the camera's processing algorithms, the lens you're using, and even the type of lighting in your environment.

With your Canon R6 Mark II, it’s a relatively high-end camera, so the color shift you're seeing could be more subtle, but still noticeable under certain conditions. If you feel like the shift is significant or distracting, you could try adjusting the white balance settings or experimenting with RAW images (if you're not already) to have more control over color correction in post-processing.
