RAW vs. TIFF/PSD - Completely different look

    What colourspace is used in generating the TIFF? (Adobe RGB, sRGB, etc.) Have you tried changing that. Also, in the dialog box when you export it as a TIFF, what setting have you used for sharpening?

    Hi Ian,

    thanks for your reply.

    As said: I tried different file formats (TIFF and PSD) as well as different color spaces in the "Edit with..." dialogue: sRGB, Adobe RGB. Does not make any difference.

    In the "Edit with..." dialogue the sharpening settings are "No output sharpening" - not sure, how it reads in English as I am using the German UI, but it's the default option, not "Disable all".

     

    However, I might have found the mistake in my workflow: before exporting I touched the input tone levels - especially the shadows and the highlights.

    I tested again with a RAW file without touching the levels and the TIFF looks much (!!!) better. It's not exactly the same but that's becuase of the missing sharpening and noise reduction in the TIFF file: adjusting those to values comparable to the RAW file (based on the camera model), I get a nearly 100% accurate result - not exactly but very close.

    Your screen shot shows that you have proofing turned on. Depending on the export recipe currently selected, I think that possibly results in output sharpening being applied to the rendering of the raw image.

    Every change in the levels tool MUST be reflected in the preview of the raw file (your image on the left), otherwise this is a bug in the software. Or did you change the levels tool on the tif file (the right image)?

    EDIT: Or did you use the levels tool in Affinity Photo...?

    I have just a hunch that the previews of exported tifs can display differently in C1 according to the zoom level of each preview.  Try comparing the raw & the tiff in C1 at 100%.

    Thank you all for your replies,

    let me run through you input one by one.

    Your screen shot shows that you have proofing turned on. Depending on the export recipe currently selected, I think that possibly results in output sharpening being applied to the rendering of the raw image.

    The sharpening indeed is not an issue. As already stated: C1 applies default sharpening and noise reduction setting to the RAW (based on the camera model, I guess). The exported TIFF by default has no sharpening / noise reduction applied - setting those to comparable settings in the TIFF leads to similar results.

     

    Every change in the levels tool MUST be reflected in the preview of the raw file (your image on the left), otherwise this is a bug in the software. Or did you change the levels tool on the tif file (the right image)?

    Yes, indeed. That's why I already mentioned, that this was a mistake on my side. Of course touching the levels (darkening the shadows and lighting up the highlights) cuts off information compared to the original file. That was an accident on my side, because the levels tool was collapsed and I did not see, that I already modified those values.

    But I can confirm, that completely untouched RAWs exported to TIFFs are nearly 100% accurate. There seems to be some kind of slight cut off within the highlights, but I guess that's normal - at least I think, that the RAW files contain a little bit more information compared to a TIFF.

    Of course, I do. ;) 

     

    In short: Seems to be fine so far and the initial problem basically was my own fault. Sorry for that!
