Aside from all the aforementioned issues about downloading and possible camera recalibrations, even with EXAF data, there is no visual reference as to colour. The phenolic circuit board is usually brownish- yellowish- redish? Whatever!
The image is extremely overexposed and out of focus/ The black clamp and the white in the background are the only visual reference points. There may not be any pure whites in the printed circuit, especially the part on the opposite side of the board which is embedded in the coloured material. Colour accuracy also depends on proper density and contrast. There is also a possibility of mixed lighting as to colour temperatures.
This is a bad test subject. Reshoot with correct exposure and include a gray card. The issue may not be a camera malfunction.
When exposure or white balance is incorrect, sometimes colour crossover occurs where you correct for one colour and another colour or shade goes out of balance.
With correct exposure, white balance and focusm you should have no problems shooting circuit boards.

Sorry for the delay getting back to this topic.
I did a factory resett and the problem went away.
Thanks to all. Really did not want to send the camera off for repair

Please upload one of the "problem" recent images, that way more savvy shooters can offer authoritative suggestions.
Lacking this any other suggestions are merely options...
From doing too many years working in tech Support...
My question(s) to you is when was the last time it worked correctly?
What has changed since then GilFrey1...
Finally have you done a "Factory" reset?
Wishing you a quick and total resolve of this issue GilFrey1

board indoors with AWB set
My Cannon 90D suddenly is producing pictures with a pronounced orang cast. Checked and AWB is set. Used last Spring for a birding adventure and no problems. This project was indoors of an electronics project . Tried adjusting for florescent lighting, no change.
Wonder if the sensor is damaged?

Thanks,
Will check my lenses!

Thanks for the link to the comparison review. That is the main reason I read UH nearly every day

My rebate took about five weeks. Sure was worth the wait to get a prepaid Visa worth $250!

Could be a bit more subtle! 22 year old grandson got the 50D when he went off to college 4 years ago. Noticed he was drooling over the 70D last time he was back east.... just saying ....
I better watch my glass! Now that could get real expensive!
Again, thanks to all who got me back on the right track..

Thanks again to all. Used the camera ,this afternoon!

Ok! Problem was exposure compensation was set to extream right. Have no idea how that happened. Not something that would be set by accident and I did not loan camera or even have someone take a picture of us. Glad I didn’t do a Reset right off!
I didn’t have my manual along on this trip (know better than to leave it home) and of course I well know that one should check the shots early in a new shoot. Longtime hobbiest, but never a professional.
My thanks to all who responded to my query. Great Forum and I at least check it several times a week.

I will try the factory reset. Forgot about that. I am getting older and tend to forget to do the obvious
Thanks

Was not just the targeted subject that was underexposed, but the entire frame and every frame, could still see details, but just barely
Gil
Lost a day’s shooting. When I downloaded the card, all shots were grossly underexposed. No warning, worked fine the day before. Thought it might be a failed card. Substituded a know good card. Test frames were underexposed. Recharged the batteries (use the grip, so two). Same problem. Changed lens, same problem. Had been using the P mode so tried the others including manual modes, same problem.
Have used this 70D for years (got it when it first came out) always reliable. If it really needs to be replaced or repaired will probably go to the 90D which is due for release in near future and repair 70D and pass it on to grandson.
Any thoughts on what I may be overlooking?
Thanks,
GilFrey
