This is the method I’ll be using to create prints sized 24×16 with a 2 inch white border for the Chestnuts House exhibition.

Required technical specs:
Canvas 28 x 20 inches
Image 24 x 16 centered on canvas

Open file as JPEG from RAW. I am using a Canon 5D and converting from RAW in Adobe Bridge @ 25.2MB.

The initial dimensions of the open file.

I increase image size to 24×16 without re-sampling. Others may prefer to re-sample to maintain DPI. But 256 DPI will be fine for exhibition prints.

Then go to Canvas Size and add 2 inch border.

This is how image should now look.
