Canon 5D vs Bronica SQ Print Quality?

Most of my gear is pretty retro.....almost all my model shoots are with the above two systems.

I recently produced a 24" print from a 120 neg (A2 being the most I had previously printed myself) and was very impressed with the IQ of the print....it is obvious I could have gone a lot larger if I wanted. Sometimes size does matter!!

I used my 5D in the same session, and would like to print up some of the digital files to the same size...and square format (so effectively dumping a third of the file data due to cropping to sq format).

I wondered if anyone could recommend (from personal experience) any process or software to allow me to achieve this; a quality 24" sq print from a 5D file.

What are you printing on? I use a Canon ipf5100 printer so can only do up to 17" on shortest dimension, for all my printing I use canon plugin for Photoshop, although Canons DPP software also seems pretty good.

I am using an Epson with Photoshop to edit the files.

It is more about file size than printer...I am reducing file size on the neg files to get the prints, but need to increase the 5D size a fair amount to get to even a 200 dpi print that is 24" sq.

Have you tried ladder scaling? (although Photoshop's standard scaling works well enough nowadays so I'm led to believe).

Doing a gentle overlay with gaussian noise may give a slight grain effect if it's too fuzzy once enlarged.
I prefer not to think before I speak. I like being just as surprised as everyone else by what comes out of my mouth.

You should only need to multiply by 1.65 to give you a 24" image at 200dpi.
It would need a very good magnifying glass to spot that difference in pixel size once printed.

For what it is worth...I am struggling to get a print where the 5D matches the MF neg scan....particularly as I have used software to improve the scan....but it might be I am too fussy!
