The UV-bright, pollen laden anthers stand out brightly against this dark background. Reference:1. L.D. Gottlieb (2016) Rafinesquia neomexicana, in Jepson Flora Project (eds.)

Andy Perrin Posted January 16, 2017 Share Posted January 16, 2017 Always amazed you get such nice photos even when you are out "in the field" (or the dessert, as the case may be). Link to comment
Andrea B. Posted January 17, 2017 Author Share Posted January 17, 2017 Lots of practice, heaps of patience and a few spoonfuls of plain old luck !! But really it isn't "always" that I get nice photos. You just don't see the really bad ones. As an example, I didn't do so well with the little Desert Gold Poppy recently posted. If I get a chance to photograph it again, maybe I'll get a better one to replace this.http://www.ultravioletphotography.com/content/index.php/topic/2084-eschscholzia-glyptosperma-desert-gold-poppy/ Link to comment
nfoto Posted January 17, 2017 Share Posted January 17, 2017 I got essentially the identical UV signature for R. neomexicana on the 2012 Desert trip with Andrea. She, however, as usual makes the better images. Link to comment
