Capture One

on: October 20, 2019 at 7:04 am

Hi Crew,

Just wondering which would be your preferred method for upscaling a phase one raw image to 40in x 60in for printing at 300ppi?

C1, Photoshop  or  On-One / genuine fractals?

I capture with an IQ3 100mp back.

My method has been to process to 100% in C1 at 16bit then take it into GF for the upscale.

Does this yield the best results?

Thanks,

Greg

Greg,

For that relatively minor upsize (<50% @ 40×53.3), I would just use Photoshop Preserve Details 2.0. I’ve experimented with Genuine Fractals, Topaz Gigapixel AI and Photoshop Preserve Details 2.0. For upsizes like this I don’t think there are significant differences. I print two-image stitch files from the IQ180, IQ3100 and IQ4 150 @ 40×90. Doing test strips first, I feel print-wise there is no discernible difference. I suspect differences crop up at <200%, but I don’t have experience doing that amount of upscaling with Phase One files.

Dave,

Thanks for your response. Just to clarify, you would not upscale in C1?

Sorry Greg, just saw this now. I’ve never done it, so I don’t know anything about its capabilities. I have a funky workflow: I process files in C1 then output a full-size tiff of just select images to a LR master catalog. That has been my primary catalog program for years, so I’ve stuck with it. Therefore, all of my printing is through either LR or ImagePrint.

I been shooting with at least 80 mp files since 2011, so the need to upsize is pretty rare. When I do, it is done post-Capture One.
