Thanks Andi, I have only submitted photos to DG PlantFiles, HMF and the databases on here, besides the albums I maintain on sites like Picasa, Flickr and SmugMug. I have had a few daylily images published in daylily catalogs and several in The New Color Encyclopedia of Daylilies,
https://www.amazon.com/dp/0881928585/ also an image was added by a German author of a species rose book and then I have sold several to a plant tag company that contacts me through the images I have on DG. Haven't pursued anything beyond that. I'd have to learn too much to try to go pro LOL!
I have a Canon Rebel XTi with various lenses but on occasion also use a Canon 7D.
