Cadmium Posted July 20, 2020 Author Share Posted July 20, 2020 Here is my UV film simulation. It is a channel mix of the BUG 5 shot.https://www.ultravioletphotography.com/content/uploads/monthly_07_2020/post-87-0-67752400-1594961284.jpg Link to comment
Andrea B. Posted July 25, 2020 Share Posted July 25, 2020 To confuse things further, there are quite a few introduced species in North America (e.g. Sonchus spp.) which may or may not appear in standard references. Floras and field guides do include non-native species. ******* Cadmium, this BUG channel mix does remind me of some of Birna's film work.I always liked the UV photos with the red bullseyes. I've been on the Oregon Flora Project to look at the Crepis setosa and other yellow Asteraceae.http://www.oregonflora.org/gallery.phpThey have a very cool collection of photos. I love finding this kind of documentation. Link to comment
Cadmium Posted July 26, 2020 Author Share Posted July 26, 2020 Yep, I always liked those UV from camera photos with the red. Basically red/white/blue looks. Not being patriotic or anything like that, just a nice look.The red/white of a dandelion, looks very appealing. Birna has many older example of that online in different places. Whatever the flower is above, it seems to be fairly prolific in my yard at this stage of the summer. Link to comment
Andy Perrin Posted July 26, 2020 Share Posted July 26, 2020 Was the red caused by using film, or was it digital and caused by the IR leak that was at that time not known? Link to comment
OlDoinyo Posted July 26, 2020 Share Posted July 26, 2020 Was the red caused by using film, or was it digital and caused by the IR leak that was at that time not known? I know that U-type glass leaks some visible red in addition to IR. Even film with no IR sensitivity will then pick this up, and perhaps this is what explains it. Link to comment
Stefano Posted July 26, 2020 Share Posted July 26, 2020 I remember (I may be wrong) discussing this here: https://www.ultravioletphotography.com/content/index.php/topic/3848-uv-the-early-days Have my posts been deleted? I basically said that if something is black, no matter the white balance or what you use to capture the image (sensor or film), it should always be black. I agree that some deep red light can still contaminate film. Link to comment
