I’ve noticed something and again I don’t know if it’s a bug, expected behavior or if I’m just an idiot…
I have a manual Ricoh 50mm lens so of course it doesn’t provide metadata. In ART I typically edit the Lens Model, FNumber and Focal Length tags to add the missing data, e.g.:
Today I took a series of images, one at each f/stop the lens offers: 1.7, 2.8, 4., 5.6, 8, 11 & 16. In ART I manually entered those values in the FNumber field for each image. However, ART changed what I entered for f/8, 11 & 16:
Image | I enter | ART shows | Export JPG |
---|---|---|---|
IMG_0964.CR3 | F1.7 | F1.7 | 1.7 |
IMG_0965.CR3 | F2.8 | F2.8 | 2.8 |
IMG_0966.CR3 | F4.0 | F4 | 4.0 |
IMG_0967.CR3 | F5.6 | F5.6 | 5.6 |
IMG_0968.CR3 | F8.0 | F6 | 6.0 |
IMG_0969.CR3 | F11 | F6.9 | 6.9 |
IMG_0970.CR3 | F16 | F8 | 8.0 |
The sidecar tag values weren’t consistent…
C:\data\images\Our-photos\20231230_Red_River_Park>grep FNumber= *.CR3.arp
IMG_0964.CR3.arp:FNumber=17/10
IMG_0965.CR3.arp:FNumber=28/10
IMG_0966.CR3.arp:FNumber=F4
IMG_0967.CR3.arp:FNumber=56/10
IMG_0968.CR3.arp:FNumber=F8
IMG_0969.CR3.arp:FNumber=F11
IMG_0970.CR3.arp:FNumber=F16
…so I manually edited the FNumber field in the sidecars to make them all “n/10
” format but it didn’t help.
Interestingly, when I disabled the FNumber field checkbox in ART for the last three images, they exported rotated 90 degrees counter-clockwise (at least as seen in XnView MP). I rechecked them and they’re back upright again.
Bug(s) or am I once again just missing something? Raws and sidecars can be downloaded (zipped) here: https://drive.google.com/file/d/1Rz7gADSSS-9AoNW0wb15LNgZvelsKhU1/view?usp=sharing
