Every time I use HR, especially for mineral photography, I learn a bit more and end up being pleased with the result. This is one I am happy with , a rather structural spessartine garnet from Minas Gerais, Brazil.
Canon EOS 7D, Canon 100mm macro @ f4.5, 8 shot stack, FOV 2.5 cm X 3.5 cm
The image is very beautiful and the stone itself looks unusual. Thanks for sharing! Would you like to share the whole stack with us so that we could place it on our new website in samples gallery? With all the copyright info of course.
