Using a 100MP colour image captured with the Fuji GFX100S, Keith goes through his B&W print workflow for a large monochrome print of an oak tree. Looks at image capture, processing and editing/sharpening for print.

The print is made, using a Epson P5000 printer, using the specific B&W print mode [ABW].

The printing is direct from Photoshop, but there is no reason you couldn't use Epson Print Layout

The paper is Innova IFA45 Exhibition Cotton Gloss 335gsm paper on a 17" roll.
