Full 32bit fidelity

    That is quite impressive highlight recovery. What camera is this from and how did you go about getting to a 32bit psd, is it an HDR file? Unfortunately I don't have an answer for you on your bit depth question, I've never seen any settings for changing the way Capture One handles different bit depths or psd files, but I'm curious how Capture One would handle the original RAW images.

    Capture One is a RAW editor and not a PSD editor.
    I can apply certain adjustments to other files like PSDs or TIFFs but only rather crude adjustments.

    As cdc suggested it's probably better to make these adjustments (highlight and shadow-recovery) directly with the RAW-file.

    This is a bracketed "HDR photo" without any tone mapping. I use these as environment maps in cg renderings. That makes sense that Capture One is only optimized for images that come from a CCD sensor.

    If I use this photo as an environment map in a rendering, all of the reflections and glare in it are as dynamic as the example above.

    With my current workflow, I need to use Photoshop to tone map each element in a shot with that full dynamic range until I'm happy. And that's fine, I have fun with it. But I'm looking for a more streamlined workflow similar to a traditional photographer. My instincts were to bring a linear 32bit render into Lightroom. This worked and looks ok but I noticed Lightroom completely crushes out any dynamic range. It turns everything pink. It looks cool but not real. My co-worker is a traditional photographer and recommended Capture One. This immediately handled things better than Lightroom. The only wall I hit was the lack of a pure 32bit dynamic range.

    I don't mind still comping in Photoshop, but I hope that companies are looking into this kind of fidelity control in a photography comping program. I've used Nuke, but there's a beauty in the simplicity of Lightroom/Capture One that gets lost when you have to jump into a complex comping process. I think there's a definite gap to fill there.

    It has less to do with the bit-depth and more with the fact that it's a PSD file.

    Capture One is not a PSD editor, it's a RAW editor. You can make certain adjustments, but it can't replace Photoshop when it comes to editing PSD files.

    So if I'm able to export a render as a .raw file, Capture One will retain the full fidelity of the shot?

    Why would you get an image back into a raw editor after being composed / edited into a PSD?

    (you might want to consider changing your workflow)

    ps: Since you use Adobe, did you succeed in the requested editing using Lightroom?

    A RAW file is, fundamentally, a chunk of data from the camera sensor, some information to assist with interpreting the file and, in most case for convenience, an in camera calculated jpg file so that applications that you might want to use to help you see what the subject matter was when the images was captured.

    You cannot write a RAW file from editing software - especially not editing software that is intended for use as a graphics editor (Photoshop for example.).

    The most common option is to create a TIFF file (about the nearest thing to a portable file retaining as much detail as possible for further editing) or a jpg (where compression will have reduced the amount of data available - but then HDR processing using multiple merged files will have done that anyway.

    Using Adobe software for the HDR merge I guess it might be possible to write a DNG file of some variety (Adobe's incarnation of a 'standardised' RAW file concept adopted by a few camera manufacturers) but I have no idea how that might be applicable or applied as a data collection file that might then be edited as if it is a conceptual raw file. Even if it could be edited like a RAW file interpretation in C1 I would doubt that there would be any benefits to doing so compared to continuing to use the facilities available in the software that created the merge that would, presumably, still have some way of allowing access to the full original data sources should that be necessary.

    So, as already mentioned by others, I think a review of your workflow and the final objectives would make sense based on what you have described for us so far.

    Or have we missed something?

    HTH.

    Thanks for the information, it looks like I'll have to stay in Photoshop. Essentially, I was wanting to treat the computer as a CCD and take the rendering directly into Capture One/Lightroom, circumventing Photoshop. I wish Capture One would hold all the fidelity of the image. When I save out a 32bit .Tiff and bring it into Capture One, it still loses all the info above 255.

    I think you probably need to stay within some dedicated HDR software that is intended for the purpose.

    If you want something other than PhotoShop there are options around.

    I have never done anything more than dabble with HDR so have not invested time or cash in any specific software on a regular basis but one product that has always looked interesting to me is Oloneo. It seems to offer some nice controls but whether it suits your specific requirements I don't know.

    HTH.

    Oloneo is exactly what I am looking for, it opens .raw/.exr/.hdr files and brings them into a full float 32bit environment 😄

    Thanks again for the recommendation!

    You're very welcome.

    I would be interested hear what you think about it once you have tried it.

    I don't see it as any sort of competition for C1 in the primary RAW converter market but it may well be a good companion in some ways.
