Compatibility of created DNGs #51

Closed curio77 closed 9 years ago

curio77 commented 9 years ago

Hello,

I'm achieving very good results using HDRmerge in general — thanks for your efforts!

However, PS CC appears to be the only application able to open the DNGs created by it, all others I've trailed fail with inconclusive error message, specifically: DxO Optics Pro 9/10 and PhaseOne Capture One Pro 8, regardless of the settings using which I save the DNG in HDRmerge. In case this may matter, I feed Olympus ORFs into HDRmerge. (FWIW, GIMP appears to have issues dealing with DNGs in general.)

Is this expected or otherwise explicable? Do the DNGs created by HDRmerge deviate from DNG standards in some known way? I might contact the suppliers of said software, but I'm not sure whether they'd be willing to put any diagnostic efforts into this seeing as the DNGs are synthetic and not created by some big-name product.

Thanks,

Marco

They don't deviate from the standard, but most programs don't support the complete standard, specifically floating-point data. So yes, this is expected. Use RawTherapee or Lightroom.

OK, I'll give RawTherapee a try.

Exactly, floating-point data was introduced in the last revision of the DNG standard, v1.4. Adobe products support it, of course, but other programs may only support the DNG standard until v1.3. The Adobe DNG SDK is free, so there should be no problem asking the developers to update to the last version.
