support for NEF files when "high efficiency" option is activated

bruno21

Hello, I am running Tonfotos on MacOs Tahoe. I use the high efficiency option on my nikon Z8 when shooting. Tonfotos considers these files as “corrupted” and does not read them while I can perfectly read them on my Mac. Is there any workaround or do I miss something ?
Sorry if there is already an answer to this question; I try to find the answer without any success
thks

bruno21 Can you please send some of those files to support@tonfotos.com for tests?

In any case, Tonfotos uses LibRaw for RAW files, if it does not support this mode, Tonfotos does not either.

Thanks for this reply Andrey. Then I have my answer: LibRaw does not support Nikon HE RAWs… quite sad

bruno21 Still I would like to ask you to send me some sample files. As you said, macOS can open them natively, we can look into this deeper.

Hi Andrey, you’ll find samples here : https://drive.google.com/drive/folders/1yEA8YvvhxfCC_g-o44dObZCZOp4cds-N?usp=drive_link
Appreciate your help

bruno21 Thanks a lot!
I checked them in my Windows 11 and here’s how standard Photos app is viewing them. First it opens normally (showing built-in preview JPEG) and after a second it changes to decompressed RAW image:

Are you sure images are OK?

In my windows 10 PC, I was able to open those sample images just fine with Photos, Photos Legacy, and IrfanView. However, in photo gallery i got the same result as Andrey (decompressed RAW image). So I think the photos are ok, just not in all apps.

Yes I can confirm these photos are ok. I did process them using capture one (mac).
And I also got the same result as described by Andrey on Win 11: for a second it appears ok (I guess there is a jpeg embbeded in the raw file) and then it goes wrong when trying to process the raw file itself.

Please, let us know if you intend to add support for the High Efficiency files. Nikon’s mirrorless flagship, the Z9 and, as stated by the original requestor, the Nikon Z8, are nearly always used in HE mode to save space. I believe you would attract many more Nikon professionals if you improved that element of your product. If this is not something you may do, I’ll have to explore another product - I can’t change my efficient RAW output for one support application, despite how eager I am to remain committed to this Tonfotos product.

AJ_Ward As I said above, we use LibRaw for RAW processing, just like pretty much all similar applications on the market, except for few programs that are dedicated to RAW processing, but those are much more expensive and honestly, not as good at photo management, since that is not their primary function.

When LibRaw adds support for new camera or some new specific format, we can update our software pretty quick.
