XnView Software

When I press F5 a MacOS message comes up asking if I want to enable Dictation?

I did CMD+R in the browser, but it didn't seem to do anything. I then opened the photo into the viewer again and it still shows Sony.

In the viewer I tried reload, but it still shows Sony.

Okay, I did that. In Edit Metadata I clicked on Clear all. Then I added only EXIF:Make and set it to Canon. But when I look at the photo in the full view the EXIF still says SONY ILCE-6700.

Hmm, that didn't work. I still get the original EXIF info.

Ahh, yes you are right.

Therefore this should work?

No, it does not change it for me. Here are some screenshots. By the way, I am still using an M2 Pro 12/19 Mac, MacOS 15.5.

EXIF info before I change it:

I then clicked on Apply and it ...

Okay, hmmm.

While in the browser view you changed the EXIF and then opened the photo into the full size view and the EXIF info displayed in the upper left corner shows all the changes you made?

Hmmm, I just now did a test with a Sony HIF file. I used Metadata | Edit to change these fields:

Make
Model
Focal Length
Lens Model
Date Taken
Date Digitized
Date Modified

After I did it I opened the HIF photo up full size in XnView MP and the information was still the old information. When I do ...

A few minutes ago I sent one Sony and one Apple photo to contact@xnview.com.

I have discovered that unfortunately this feature does not work for Sony HIF photos and also does not work for Apple HEIC photos. It does work for JPEG and TIFF photos.

Oh, one more, thing. The Metadata | Edit option is not available when you are looking at a full size single photo.

Hmm, I have a vague memory a few years ago when I first started to use Xnview MP that I had the same behavior you have, but somehow I found a way to change it. I just now looked through the configuration options and I cannot find what I may have changed. I am using an Apple Silicon Mac, but I also ...

When I click on an image and hold the mouse button down it magnifies to 100%. When I release the mouse button it goes back to fit the screen. I do not use the SHIFT key. I do not recall if years ago I set an option to make this happen or if it is the default behavior. I think this is the same ...

Playing around some more I found that hidden inside Edit there are some more options. I will give it a try and report back.

I installed 1.9.2 on my Mac. When I select a photo and then look at the Metadata menu I see Edit comment, Edit IPTC, Edit XMP, Edit GPS data, Edit, and Change timestamp. But I cannot find where I can set/change:

camera
lens
focal length
f-stop
shutter speed
ISO

Maybe I am looking in the wrong ...
