Dear lamiaceae...
When I edit my images taken with my Sony A7R4, I use four different editing programs. I have noticed that the metadata is removed by one of them, but I am not sure which one. (Topaz denoise; Topaz sharpen; Topaz Gigpixel or Photoshop CS4) I wish it didn't because I have to add it back if it is needed. Sometimes if I have deleted the original image, I can't get the metadata back at all. Since I often take 1500 images at a game, I can't keep all of them on my computer because I have been shooting indoor soccer for 42 years. Shooter41

Fine, you can add me to your list. I do think about lighting more than most I guess. Also glad I was helpful. I more or less pissed off others in other posts today for some reason.
Though, I thought Na is yellow and Hg is blue. But the corrects are sometime opposite from what one might think. But yes, you have to manually correct Na or Hg and other odd lights as the camera has no auto or preset for those. So I do AWB too alot. You have the right idea.

Canon makes some of the highest ISO cameras with a max ISO of over 4,000,000. Your camera has a max ISO of 102,400. The 4294941760 shown in your meta data is way, way bigger than 4 million or 102,400 and is more than likely a blown field.
It’s a Sony so thaz likely your actual ISO ....
..... plus some other stuff ;-)
The Sony a7S series tops out just shy of the ISO half million mark.

I can just imagine Paul clearing everything up by pointing out that a mixed metaphor is worth half an hour of photoshop

Looks like a phone number, but area code 429 isn’t assigned in the US.

OK, good. Nothing sinister or a cover up like a couple of us were implying. Sorry. My Ps CS6 Extended does not strip metadata. And I have not noticed that issue with the ancient versions apps I have from Topaz and Nik. But you are using Gigapixel and I do not have that at all. Also there are options in Ps to remove metadata when Saving. I never choose that but perhaps you have it switched on to remove your Exif/Metadata from Saves and Save As. Good luck. You my need a true graphic files guru.

Sometimes computers/software can produce ridiculous answers because they can't go beyond certain values, i.e., it checks disk space free and it's max is less than the drive you have, answer comes out as non-sense. Kind of like the year 2000 problem. Seen error stating memory or drive was too small, when actually too big.
Bar code translation or ISO std value.
None really make sense, but if only on 1 pic. memory storage glitch for me.

429 is my unique private “unlisted” area code. No one else can use it.

EXIF data likes to be stored as a fraction of two integers, and sometimes EXIF readers read out that way. Is it possible the '1' was really a '/' or something like that? 429494/760 = 565 ?

If ISO can go that high, then why do we need Large aperture lenses
Large aperture lenses allow for shallow depth of field and blurring of the background. Do you want to take a portrait of someone standing in front of a busy background and see all of the detail?
