I got rid of the jet exhaust based on feedback I got over on the Aviation Art forum. The photo has a yellow tinge from the sunlight. I'm wondering if I should go over the sky with the Prisma colorless blender, or nail polish remover, just to make it smoother. Has anyone here tried NPR? Are the results satisfactory?
I think I'll leave the a/c as it is and not burnish it.
@Attalus - My explanation of the technique was terrible. I will post some photos of the technique.
PS: Do other artists here take photos of their work or do you folks scan it? I scanned this one and it came out horribly over exposed.
