Title: Workflow with Capture One - Topaz - Qimage One
Post by: cortlander on December 16, 2022, 08:11:31 PM
Greetings:

I have Qimage One - latest version running on MacBook Pro Max 16 w 64GB.
I have an Epson SureColor P800
I process images from Canon EOS R5 on Capture One latest version.
From there I do noise reduction and/or sharpening in Photo AI.
Next I export to a TIFF file usually with profile set to Prophoto.
Then I open the photo in Topaz Gigapixel and size it to a resolution of 720 ppi
before opening it in Qimage One, using an ICC profile to match the paper.

The part that I am confused is:
1. When exporting from Capture One to a TIFF, if Prophoto profile OK or should I be using something else.?
2. In Qimage One does "Printer manages Color" automatically select the right profile or should I manually choose the correct paper profile?

Thanks.

ProPhoto is fine but make sure you save as 16 bits/channel.  I use Adobe RGB because ProPhoto is unnecessarily large (no device can capture color that wide).

Let printer/driver manage color will prompt the printer driver to pick the right profile.  It's always best practice, however, to select the ICC profile in Qimage instead: don't leave that important step to the driver.  With the profile selected in Qimage, you can use relative colorimetric intent and you'll have access to black point compensation (something printer drivers don't offer).  So when possible (when you have the ICC profile for the paper you are using) select it in Qimage instead of letting the driver manage color.

Mike

You're welcome.  And just as a calibration, you should probably just take the originals and print them in Qimage without touching them.  Compare those results to all the extra steps with the AI Gigapixel, sharpening plugins, etc.  I've lost track of how many times people do that and the "straight Qimage" results are as good or better than all the extra pre-steps.

Mike
