Hmmm, I wonder if this is a case of classic inadvertent jogging of the dial on the back of the camera. I'm not sure exactly how EV is set on the A6500, but I think the rear dial is involved?

I've had the NEX-7, A7, and A7 III and I've been capable of making adjustments on that dial just through hanging the camera over my right shoulder. Usually it is ISO (NEX-7 and A7) but on the A7 III I can move the drive mode setting to e.g. Continuous WB bracketing. Harmless but not helpful! Might be worth checking on your camera?
Mr Stanbury;
I've gone back over my photos and that -1.3 EV pops up more than it should but at no time w the devastating affects of these Grand Canyon photos. I suspect your diagnosis is correct, maybe w that particular setting, perhaps we have found the problem?
thank you Coast

I can't help feeling that using Autumn leaves may be part of the problem.
I have never used any of these settings.
I do know that underexposing a little can result in richer colours.
I do this with sky’s in particular and autumn leaves. I usually reduce the exposure on landscapes enough so that the clouds have lots of detail and the sky looks a deep blue rather than a pale blue.
I suspect that the autumn leaves setting is trying for a similar result ending in underexposed photos.

Well, I can hardly imagine. Boost saturation yes, making colors warmer yes, but underexpose by about 1.5 stops? And if that would be true, why then is the supposedly beneficial effect reversed on the camera monitor?

You could simply validate this theory by making an image with the camera set on Autumn Leaves, then again in Normal, while keeping all other settings the same. See what difference that gives.

Hello;
I downloaded the images from my card into Photos, then into DoX and then Luminar and got the same faded results w each
I know that at the beginning of the day, I like to keep things simple.
I set the camera setting on Autumn leaves because it was that kind of day and didn't bother the rest of the day because the photos looked fine in the EVF and display.
I can tell you I will make sure from now on the ev will be set @ 0.0

but it was a spectacular day that will stay w me forever.    
thanks guys for all the help and expertise. I appreciate it very much    
All the Best _____Joe

I wonder if Photos 4.0 is treating these ARW files improperly. It occurs to me that it might be processing the images that are already 1.3 stops underexposed as shot, and then improperly subtracting another 1.3 stops to make its default presentation.

You could experiment by shooting a test scene at -2, -1, 0, +1, and +2 stops and then seeing if the discrepancy between the embedded JPEG and the Photos 4.0 default conversion gets even more extreme as the numbers diverge from zero.

The good news either way is that you should always be able to override the program's default presentation and make your own adjustments as needed to 'match' the embedded JPEG.

Well, you're showing us converted JPGs instead of the original ARW files.

However, EXIF confirms that original ARW files were underexposed for the lighting conditions. You were shooting in 'A' mode at ISO 200 with -1.3 stop exposure compensation. If EC had been at 0 or maybe even slightly on the plus side, you might have had perfect ARW results. So, the dark results we see above are presumably what the camera settings produced.

The image that looks just fine on the camera's display and for a brief moment when loading the ARW version is the embedded JPEG thumbnail that exists in every ARW file. The processing applied by the camera to that embedded JPEG thumbnail made it look great.

I've often seen considerable discrepancies between ARW brightness and embedded JPEG brightness in my own images, but they typically occur only with extreme examples like night sky photography. Whatever the reason here, the camera did indeed fool you by producing a nice looking JPEG thumbnail from a very underexposed ARW image.

One experiment you can try is to convert those ARWs using something other than Photos 4.0. Maybe Sony's own RAW converter (either the old Image Data Converter or the current Imaging Edge) or some other tool will somehow produce better default results than what you're getting with Photos 4.0. They'll still look underexposed, but maybe not as much.

Not sure if it's what's going on but DRO at a high setting might boost the viewfinder "brightness" for shadow areas while at the same time not being captured in a RAW without some heavy editing.

Have you tried Sony's IDC, now discontinued unfortunately, as it will automaticly apply any in-camera tweaks to a RAW file?

Joe, these look to me like underexposed raws and that somehow the in-camera jpg is brightened (based on your jpg settings or camera LCD brightness), so fooling you in the field.

For instance the first image is f14, 1/1000 at iso 200.

Following the "sunny 16" rule I would expect such a scene to require f16, 1/200 at iso 200. So your shot is about two stops underexposed vs. what is expected, explaining the too dark image.
Mind the bandwidth of others, don't link pictures larger then 1024 wide or 960 pix high, see here

Hello
this are the photos downloaded into editing programs (all of the programs)
above I stated for a second They look fine just like in the camera and then they fade right away into what they look like here
Thats why I said it looks like I lose half of my data, for lack of a better description.

Joe,

Just guessing of course, but this sounds more like your monitor not displaying the photos correctly than a problem with your files. Didn't you say in a post a couple years ago that you were using a TV as a display? If you are using a non calibrated monitor, the default setting for many LCD monitors are normally much too bright for photo editing

I would recommend that you shoot either just jpegs or raw plus jpeg at least until you get this sorted out.

Are you using On1 Photo Raw 2019 now? If so I believe it is using On1 Standard to display your RAW photos because when you click on the develop tab that is what is set as default. What color preset (Creative Style) do you have your camera set for? I normally set my cameras for Camera Standard.

As Syber Says, it would be helpful if we could see one or two of your files.

Kelly

I see some of the earlier photos you posted in the thread are no longer showing up.

Do you have a way to make a couple of the original files from the memory card available? If they look bad to us, then your camera's display is fooling you.

Sorry members, but this unresolved problem is still keeping me up at night:
How could I go all day shooting the Grand Canyon and not know what I'm doing? I remember looking at the photos in camera and they looked fine! on that day.

I still have the memory card of the shoot, put it into the camera, played them and they looked today as the day I photographed, fine. Not like they download into the editing programs, all of them, totally faded.

So what am I to do? If I can't trust what I see in my display. Has anyone ever heard of this?
thanks_______Coast

Thanks Ross, Syber, everyone,
You all have been really helpful. I'm able to enjoy the photos now and re-live that wonderful day.
Not being in the camera or photography business, or anywhere near it, I just like going to beautiful places and taking beautiful photos (hopefully). I have relied on this forum often and often gotten a lot of help. This is the only forum I visit, I don't have time for more, except Flickr.
Thank you, I much appreciate it
Now if I can only stop making mistakes🤓

I'll be posting the completed Grand Canyon album
Still busy working on all the other places I photographed. (those pictures all turned out as good as I hoped)

thanks again_______Coast

Glad you managed to sort your image out and solve the mystery.

My suggestion is to shoot in manual mode
