DaveO Posted April 17, 2015 Share Posted April 17, 2015 This uses a Fuji S3 UVIR camera so is probably not very relevant Flower Colours through the Lens: Quantitative Measurement with Visible and Ultraviolet Digital Photography (2014)http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0096646 This uses the red channel of a modified Nikon D70S Linearisation of RGB Camera Responses for Quantitative Image Analysis of Visible and UV Photography: A Comparison of Two Techniques (2013)http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0079534 Dave Link to comment
Andrea B. Posted April 17, 2015 Share Posted April 17, 2015 Perhaps Raw Digger would have been of some use in these experiments for recovering the linear data ?? Link to comment
JCDowdy Posted April 17, 2015 Share Posted April 17, 2015 Dave,We discussed these Garcia papers about a year ago. Lots of good comments to review. Andrea,Your recent posts using Raw Digger had me thinking exactly the same thing! Link to comment
DaveO Posted April 17, 2015 Author Share Posted April 17, 2015 John, Thanks, that just proves that I'm going around in ever decreasing circles :) Dave Link to comment
Andrea B. Posted April 18, 2015 Share Posted April 18, 2015 Well, I suppose eventually you will converge to a still point, Dave !! :) Link to comment
rfcurry Posted April 18, 2015 Share Posted April 18, 2015 Dave, are you feeling flushed? :) Link to comment
DaveO Posted April 19, 2015 Author Share Posted April 19, 2015 Here, from the same stable is something about iridescence Is floral iridescence a biologically relevant cue in plant-pollinator signalling?http://onlinelibrary.wiley.com/doi/10.1111/nph.13066/abstractand responsehttp://onlinelibrary.wiley.com/doi/10.1111/nph.13178/abstract Dave :) Link to comment
Andrea B. Posted April 19, 2015 Share Posted April 19, 2015 I didn't see the mention of UV in those papers. Sometimes the UV iridescence is quite spectacular. Link to comment
JCDowdy Posted April 19, 2015 Share Posted April 19, 2015 ....eventually you will converge to a still point..... So shall we all. Link to comment
Andrea B. Posted April 20, 2015 Share Posted April 20, 2015 Yikes!!! We all become some sort of singularity, I suppose? :) Link to comment
DaveO Posted April 20, 2015 Author Share Posted April 20, 2015 What's the UV signature of a Black Hole :)Dave Link to comment
Andrea B. Posted April 20, 2015 Share Posted April 20, 2015 Very absorbing I think. :) Link to comment
JCDowdy Posted April 26, 2015 Share Posted April 26, 2015 What's the UV signature of a Black Hole Dave Black Hole's Disk is Flooded With Ultraviolet Light Link to comment
Andrea B. Posted April 26, 2015 Share Posted April 26, 2015 omg that is amazing ! So it would seem to be very reflective instead. Link to comment
enricosavazzi Posted May 7, 2015 Share Posted May 7, 2015 omg that is amazing ! :DSo it would seem to be very reflective instead.Only what is in front of the black hole (and probably what is at its back, as well, since it bends light around itself). Link to comment
