Re-import image while keeping edits?

Karl Buhl
I have 20-30 TIFF files in which I have invested many hours of Capture One edits. These TIFF files are ~ 55MB each. I would like to rescan these TIFFs with higher resolution images (new scanner can deliver ~ 1GB per TIFF).

Is it possible to re-import the underlying TIFF files with the newer hi-res scans (with the same file name) while maintaining all existing edits?

If so, how would one do that?

Thank you.

    I think that would only work if the files are practically identical - including resoltion. Otherwise there would be a mismatch between the layers, especially when using a layer mask.
    It might work if your files are don't have a mask, but then you might as well copy/paste them...

    So - if you're working with layer masks it won't work - but if you're just using layers it could work.

    You don't need to re-import as if it was the original file , just use a different name and copy the adjustments form the 55Mb Image to the new one.

    However, as C-M-B has mentioned, unless you have made all of the edits at the background level there could be some mismatches in the results.

    If your adjustments are based on a colour selection mask the dimensions would not matter BUT potentially it might be important that the scan delivers the same colour rendition as your original 55MB scan. If any colour editing work is extremely specific then the matches may not align. If it isn't then you may get the results you want. However, if there is as much work in the processing as you have indicated I would guess you are working in some very specific areas of the image.

    A 1Gb file is huge and may not give you the advantage you are seeking.

    By way of example I have a 2 1/4 inch square negative (B&W) that I scanned on my Epson scanner 10+ years ago. A potential client was interested in a version of it but only a very small part in the centre. It looked very grainy, being 400ASA film from many years ago, so I had it professionally drum scanned at much higher resolution. A much larger file.

    Apart from some very slight differences in perceived exposure if viewed at matching size on screen, the only difference I could see was a tiny amount of additional definition for the edges of the film grain. The overall result was no better than my desktop scanner output (Epson 4990)

    As the potential client wanted a wall sized print that was not going to matter.

    Also bear in mind there are limits to the pixel dimensions that Capture One will work with.

    HTH.

    Thank you for the input.

    Generally, when working with the 'Adjustments Clipboard' to copy and apply adjustments between images, does the 'Adjustments Clipboard' also copy layers (including masks in layers)—or only adjustments made to the background?

    Specifically, I could see that copying luminosity masks might not work between different images with different scan resolutions.

    Interesting test results with your different scan resolutions. Seeing a difference obviously depends on the output size. Based on your results, do you think you would see a difference between a 55 MB scan and 1 GB scan with a 60-inch (152 CM) or larger width?

    Thanks again.

    Could keep the dimensions the same, but use a higher PPI?

    The clipboard allows you to copy just about everything. If you open the clipboard tool and have a look at it you will see all that is possible to copy and you can also see the controls you have for defult copy choices for your regular needs.

    The Luma mask selections are actually portable becuase they work on Luma values not a pixel map at specific poxel positions (unless the mask has been rasterized to "fix" it.)

    However there is potential that the original Luma mask settings may not give exactly the same results for another image that may have notably different critical values or a specific adjustment - especially if produced from a different scanning device at a different resolution. Whether the difference is truly noticeable would depend on a number of factors ... but if it isn't noticeable then one starts to wonder about the relative benefits of the different scans.

    As for my scans - I don't think there would have been any obvious difference. Once scaled to the sort of size the prospective client was hoping for it was a little like the print on an advertising display. Viewed at the intended distance it would look OK. Viewed close up one was looking at the detail of the grain in the processed film and other than slight exposure differences and think like, the grain looked very similar - as one might expect.

    That's not so say that your results would be the same but it is something to consider and check. I spent hours trying to tease a little more from the negative and the pro-scanned file. It was not, in the end, worth the effort but was interesting at the time.

    After some experimentation, you are correct in that copying adjustments from scan 'A' and applying those adjustments to scan 'B' (same image but different scanner and resolution), applies adjustments that are incompatible and senseless to scan 'B'.

    You called that right.

    Cheers
