My son graduated from Boot Camp at MCRD San Diego this last week. What a place for photo opprotunities. When I saw these Drill instructors back lit by the morning sun, I knew immediately that I was going to do the image in Gum Oil, there is nothing quite like it for a high contrast image.:blushing: This one was rubbed first with a combination of Napthol Crimson and Rose Madder, then the interior was re rubbed with a combination of Prussian Blue and Thalo green. I like this combination to produce a dark warm black better than using a single black pigment such as lamp black, plus it gives me the option to leave the border the original color.
