I'm not normally a fan of the "west end of a bird flying east".

Laughing Kookaburra : Dacelo novaeguineae​

Another one for you, Hali.

I am fascinated by what birds look like in flight, even if 'it ain't pretty'. I had no idea that the spring-off caused the kookaburra's rear end to curve up like that.

According to DxO PureRAW, the camera-to-subject distance was 1.5 metres. Does any one know: do our R-series cameras (mine's an R5) write this information to the CR3 file? Is DxO the only software company that knows how to (or could be bothered to) extract this camera-to-subject metadata?

And for those who prefer a more conventional image…

Yes, it appears that the R-Series cameras do write the "Approximate Focus Distance" into EXIF, according to ExifTool. When I looked back through my Lightroom catalog (more on that below), the R, R5, and R7 all have this info in the raw file. Also, looking back my 7D raw files also have this info, but the raw files of my first DSLR, the 30D, do not have this information.

Note that, at least for me, the distance value provided seems to be "quantum", in the sense that there seems to be distances like 6.1 m and 6.8 m, but nothing in-between even when the focus point changes incrementally.

"Is DxO the only software company that knows how to (or could be bothered to) extract this camera-to-subject metadata?"
Lightroom Classic does not show this info in the default metadata, but the Customize button at the bottom of the metadata window can be used to add additional metadata to view in the window. There are two distance choices available; Focus Distance and Subject Distance. The proper choice for the R-series seems to be Focus Distance, which allows viewing the (approximate) distance value in Lightroom.

And if you want to go "back in time" in the Lightroom catalog, you might need to choose the photo(s) you want to display the distance data for and use the "Update DNG Preview and Metadata" option in the Metadata dropdown menu.

A male eastern bluebird treated us to an infrequent visit: we see them a lot in the winter and spring, but they are less visible in July and August

A mourning dove with wings up. The dove was not taking off but was actually balancing itself as it turned itself on the branch
