To the OP, is there a particular reason why you are trying to look at a TIFF file in Phocus after conversion? Just curious...
When editing weddings I use Photoshop on around 10% of the images, mostly minor touch ups of the faces of the wedding party and close family on images where their face is prominent in the frame. Capture One can handle handle basic dodge and burns, remove minor acne, and tidy up isolated stray hairs; more complex retouching requires Photoshop.
This is my wedding editing workflow, which I find works very well for me:
1. Raws go to the Capture Folder (into subfolders by time of day)
2. Edit by star rating; 1 is delete, 2 is retain just in case, 3 and above will be provided to client, 4 and above will go on the public online gallery, 5 and above are hero images for teasers/Instagram/portfolio etc.
3. Images that require PS editing are marked with a yellow color tag.
4. All 3+ star images get a light pass through with basic exposure/white balance/crop and appropriate styles applied (I'm loving the Fuji 400H style we developed earlier this year for our wedding shooters). All 4+ star images get more advanced tweaking (dodge/burn, color adjustments). All 5+ images get as much tweaking as I have patience to explore.
5. I filter by yellow tag and process those images using a Process Recipe that I've named "Retouch Alongside" which
---- creates a 16 bit TIFF
---- places it in the same folder as the raw (not the default option of the output folder)
---- names the tiff [name of raw]-RT.tif (standing for "
Re
Touch")
---- includes the Rating in the metadata of the TIFF
---- opens that TIFF in Photoshop
6. I retouch the yellow tag images and when I'm happy with the result, I consolidate the layers down to 2 or 3 layers, save, and close.
7. Back in Capture One when I'm ready to process my deliverables/derivatives I filter by not-yellow-tag and select all. The result is that I've selected all the images (as raws) that didn't require retouching and all the retouched TIFFs of those images that did require retouching.
8. I process those images to medium sized watermarked JPGs for the web, non-watermarked full-size JPGs for client delivery (unless the client is on the nerdy side or specifically requests TIFFs), and TIFFs of the 5-star images for my archive (all raws, including 1 and 2 star images, also go to my archive).
9. After client accepts delivery, orders prints/albums, and a good feeling time has passed I move that wedding's session from my Work folder to my Archive folder, empty the session trash (the images marked 1 star in step 1).
In this way I can put images that required retouching and those that don't through the exact same workflow. I retain, for the retouched images, all the C1 tools I might use after the near-final-edit stage – the ability to use the output recipe options in Capture One, fast cropping (including batch cropping), using the B+W tool if a section of the story seems better told in B+W. This is a workflow we teach in
Capture One Masters Program. Since I use the Phase One IQ3 100mp for large sections of the weddings I shoot I'd be dead in the water trying to use this workflow if I couldn't view those TIFFs in my raw editor.
Anyway, the point is there are VERY good reasons in some workflows to quickly/easily view processed TIFFs in your raw editor.
