nfoto Posted May 22, 2017 Share Posted May 22, 2017 Good, very illustrative examples indeed. The overall lighting is exemplary. Kudos. The UV rendition of the I. pseudacorus sometimes more clearly show a bi-colour pattern (yellow and blue). I assume one needs a lens going a bit deep into UV, such as the UV-Nikkor, to make this rendition strongly manifested. Link to comment
