nfoto Posted January 21, 2016 Share Posted January 21, 2016 Very interesting UV flower this one! I had to go back and forth between the UVIFL and Vis image to see that you hadn't superimposed another flower :D Link to comment
colinbm Posted January 21, 2016 Share Posted January 21, 2016 Marvellous Dave, the UVIVF is so sureal.Col Link to comment
Cadmium Posted January 21, 2016 Share Posted January 21, 2016 Dave, Very interesting UVIVF pattern! Link to comment
Andrea B. Posted January 21, 2016 Share Posted January 21, 2016 What an unusual flower ! Its fluorescent appearance really makes you think that there must be some reason for this unusual Visible look under UV light. Dave, do you have an IR filter? It would be interesting to see this one in IR. Link to comment
DaveO Posted January 21, 2016 Author Share Posted January 21, 2016 Just have a look at the two Goodenias (pinnatifida and varia) as UVIVFL and you will see similar fluorescence patterns. I will re-do the other Goodenias when they flower again next spring if they haven't succumbed to our dry hot summer by then. Similarly for the IR, something to do later. The 'bulls eye' region which is black under UV goes orange or something in UVIVFL, so I guess that is perhaps due to overlapping fluorescence colours (or something). Perhaps the green UVIVFL is also a mixed light effect. Link to comment
