My Omega C700 enlarger has a color head but the red safety filter is long gone. I wonder, is there a dichroic setting that would be safe for orthochromaitc papers? Sometimes I work without an easel, and it would be a good aid for aligning the image on the paper. Thanks.
there is no such combination,but you can try a max cyan setting and check if that leaves you sufficient luminance to see the image. it should protect the paperadequadtly.
