Possible Alteration of Lens Details on Export by Affinity Photo 2 Beta v.2.4.0.2222 (Windows)


Recommended Posts

I am running Affinity Photo 2 Beta v.2.4.0.2222 on a Windows 11 PC.

I round-tripped a DNG file from Excire Foto 2024 to DxO PureRAW 3. I then exported the resulting linear DNG to Affinity Photo 2 Beta. On export from Affinity Photo 2 Beta, I noted the details of the taking lens had been changed.

The image was taken with a Nikon D800 and a Nikkor AF-S NIKKOR 24-120mm f/4G ED VR, but the TIFF exported from Affinity Photo 2 Beta shows the taking lens to be a Tokina AT-X 24-70mm f/2.8 PRO FX.

I have contacted Excire and they do not believe their application is responsible for the metadata change. As can be seen from the attached screenshot, it appears that DxO PureRAW 3 is using the correct optical module. Could Affinity Photo 2 Beta be responsible for this issue thanks?

What happens if you try it with 2.3.1? 

Can you share a copy of the file at each stage (before loading into Exciro, after Exciro, and after DXO PureRaw 3)?

Walt,

I have just repeated the exercise with v 2.3.1 with the same results.

As it is getting a bit late here in North West England I will conduct further test tomorrow morning.

Just thinking of the best way to share the rather large files, I am no computer expert?

I have already contacted the manufacturers of Excire Foto 2024 which is a DAM: they are of the opinion the problem does not lie with them.

I think I will open the raw file directly in Affinity Photo 2 & the beta and see what happens?

I will also see what happens if I open the file directly in DxO PureRAW 3 and then process it in Affinity?

I will also see what happens if I process images taken with different camera/lens combinations.

 

Many thanks,

 

Patrick

I have done further testing.

Files processed in Affinty Photo 2 & Affinity Photo 2 Beta; when synchronised with the Excire Foto 2024 DAM the taking lens is being changed from a Nikkor to a Tokina lens.

When the images are opened in Adobe Lightroom Classic, DxO Photolab 6 or 7 and FastRawViewer the lens data is shown correctly. Utilising the metadata panel in Affinity Photo 2 also shows the correct Nikkor lens. In addition if the jpeg with the incorrect metadata is sent from Excire Foto to Affinity Photo 2 the correct Nikkor lens is displayed.

Any observations would be most appreciated.

I will raise the matter with Excire as it looks to be as they are the culprits.

Many thanks,

Patrick
