Yellow And Red Rose In The Light
I used side lighting for this rose because that creates the shadows that reveal shapes and textures. The flash was a Yongnuo, in manual mode, in a 24 inch gridded soft box positioned at camera right at 4 o'clock. Fill light came from a hand held mirror at camera left.
I've photographed a lot of plants and flowers, because they're all around us, work cheap, and never complain. I have an album of these images with over 1200 pictures, and for each one, I have described how I lit them, in case you're interested in that kind of thing.
Other pictures that I've taken of roses are in my creatively titled Roses album.
