Why are these photos so different?

A few weeks ago at the Singapore Zoo my husband and I photographed this beautiful cheetah at the same time from virtually the same spot. My husband’s (Sony RX10 IV) picture is much warmer than mine (Sony A6600). Neither picture has been altered in any way. Can anyone tell me why the pictures are so different?

The answers are in the EXIF data.
The top / yellow has a manually set WB. Something done by the photographer in control of that camera. The bottom image has Auto WB as determined by the camera.
There's other differences such as the metering mode, the focal length, the aperture, shutterspeed and ISO making the exposure completely different between the two images. But, the WB is the most obvious beyond the different focal lengths of the zoom lens.

That was a fast answer! I was looking again at the Exif data, noticed the same thing and was about to amend my question, but you beat me to it. Thank you!

No worries. Glad you saw the same.

I don't know Sony , but different cameras jpegs have different picture quality settings that are chosen by the user or assigned automatically by the camera. Combinations of things like saturation, color tone, brightness, contrast, etc. Are grouped to make up different style categories like standard, landscape, faithful, portrait, etc. These are usually customizable by the user that wants to bother, or under full control in raw.

Also, some sensors / image processors handle light differently than others, so one camera may produce a different tone / etc image from another...even when both use identical WB, Aperture, etc. then, too, different lenses handle light differently. The different coatings, and other factors, may producer deeper greens, brighter yellows, etc, from another lens when the two shots use the same camera, WB, etc.

The bottom one is more correct. Look at areas that are supposed to be gray such as the rock and dirt. The top one is contaminated with yellow. Probably a white balance issue somewhere.

Help a beginner please.
How do you find the EXIF data for these pictures from the UHH post?

Not so sure of that. “”Correct” is tricky. Our brains do a lot of image processing that we are unaware of. I tends to “normalize” what we see. Snow comes to mind - the light actually reflected from snow in shadows can be quite blue but what I see is white. And lord help us if our brain didn’t adjust what food looks like in the supermarket under fluorescents - we’d never eat again!

This is why shooting in raw is a good idea.
One click in post will typically fix.
Which one do you remember as being correct?

There are multiple options:
1) Download the file and view the details of the file properties using your computer's operating system.
2) Download the file and open in your preferred digital editor and view the image details.
3) Search for available EXIF viewers that are supported by your browser. I use a free tool called Exif Viewer that installs into Google Chrome. Then, you just open the file in another browser window, rather than downloading the file, and let the Exif Viewer display the available information.
Note, the EXIF data has to be included in the file. The photographer may have intentionally, or inadvertently, removed via their processing the EXIF data from the file posted. In that situation none of the options above will yield additional details about the camera and exposure when the image was created.

I use a free downloaded app called ImageExifViewer as suggested me by CHG CANON Just drag a photo into the app. The relevant data is listed within the app.

Thank you photogeneralist & CHG CANON.
I about went nuts trying to figure this out.
I couldn't get the Exif CHG CANON got when I used Photoshop
or Bridge. Then I discovered that if I clicked on (Download)
beneath the picture I got more info in PS and Bridge. When
I realized photogeneralist said to "drag a photo" then I was
able to see what I was looking for by using "Online EXIF Viewer".
I could never get the downloadable app to work for me. I think
there were too many steps for getting it installed.
So....Thank You both guys. I now have a new tool in my kit.
