Issue with file size

    I just tried with a 34.9 MB Nikon raw file (NEF) and processed it in Capture One to a 100 quality JPG. The JPG comes out at 27.2 MB (as reported in Finder on my Mac). (So I have the JP quality slider set to 100 in the process recipe and the scale set to 100.) This compares to 8 MB for a JPG from the same NEF file if the quality slider in C1 is set to 85, which is what I usually use.

    A 20.9 MB Sony compressed raw file (ARW) came out at 13.1 MB when process to JPG at 100 quality.

    So I would expect that your JPG would be a rather larger file size than you are reporting. Are all the settings in your process recipe what they ought to be (that is, as described above, 100% scale and 100 quality)?

    I processed them out as raws and then opened the raws in photoshop and saved those as jpegs. Do you reckon the jpegs will be bigger if I process them directly into jpegs ? The raws that are processed come to 15mb so hopefully the jpegs will be around 8?

    If you are exporting a CR2 file you are simp0ly sending the file to Photoshop as it came out of the camera, untouched by Capture One.

    My guess would be that PS is pretty much just extracting the jpg preview file embedded in the CR2 file and giving you that.

    RAW, and all other files, will change in size depending on many factors, the type of content and colour mixing being one.

    The images may or may not be the same "RAW file dimensions in pixels" in reality but may be shown as being that way. But that does not mean that the file size and all of its data will be a consistent size.

    If you are sending the CR2 file to PS as a CR2 file, for what are you then using Capture One?

    If you process them as raws, and then open the raws in Photoshop (PS) you won't be getting the adjustments you have done in Capture One (C1) when you get into Photoshop. If you need to do some work in PS in addition to what you have done in C1, you need to (1) do what you want to do in C1, then (2) get them to PS using Edit With. (Not Open With - Edit With takes them into PS as a TIFF, or whatever format you choose, with all the work that you have done on them in C1, but Open With just opens the unadjusted raw file in PS), then (3) do whatever extra it was you wanted to do in PS.

    Unless you have work you can only do in PS, using tools like cloning, you may find that you are just as well to do as much as you can to the file in C1 then process it to a JPG directly from C1.

    Just take the outputted files and double the dimensions in photoshop and save them.

    Other way is to just add noise in photoshop.

    It's annoying when clients demand file sizes, got nothing to do with the quality of the image. Morons.
