I thought about this for a while, and you may have a point and C1 will address it. However, I personally would never want C1 to handle large tiffs, over 1GB (not sure if you have layers or just huge resolution files). Note, I did discover that you can save 2GB or large tiff files, with layers from CC or CS, just never had tried it always used PSB format.
1. If you have layers, then C1 will never do the files justice. I realize that most people keep a layered file as psd, but I wasn't sure if you were using the tiff extension with layers or not. I often do.
2. If you don't have layers and just huge resolution files, still not sure you can expect C1 to work with these. C1 to me was always meant to work with a raw workflow, i.e. catalog all raw files, or work with raw files in a session mode. To ask C1 to import a 4GB tiff, (still not sure how you are
saving this as I thought anything over 2GB had to be psb at least in CC or CS). But still that is a huge file and not what C1 was designed around.
3. I believe you mentioned printing, in the first post, I would never use C1 for printing, it's not a strong point of the software, and again it was never designed as a print engine. The fact that C1 can print, to me is moot, as it's just not what C1 was tasked for. You don't see Phase One pushing
printing with C1 either.
You feel you made the investment in the software for it do everything, but I don't feel it was ever meant to do that. Capture One started out as a raw conversion software and over the years has grown, to add many other features, but working with tiff files created by other software solutions, CC, LR etc. I don't feel is a high priority.
Phase One may change the catalog to handle the larger tiff files, however again, based on issues that exist with the current catalog setup, not sure I would even want to risk such large files. (read back in this forum or the Phase One forum on posts concerning issues with cataloging in C1)
Just another viewpoint.
