Andrea B. Posted October 22, 2016 Share Posted October 22, 2016 Following Member Andy's suggestion to try IR imaging of these berries, I embarked on the Great Pokeweed Expedition of 2016, trekked over to the local cow pasture and successfully gathered a few berries. As mentioned elsewhere, it did result in temporarily stained fingers and forehead, but that soon wore off. The translucency of the Pokeberry case in IR is quite interesting. I opted for a click-white conversion of the IR false colours and saw the seeds inside the case become a pretty false blue. Camera & Lens: D600-broadband + Coastal Optics 60/4.0 Infrared: f/11 for 1/5" @ ISO-100 with B+W 092 IR-Pass Filter and On-board Flash Infrared: f/22 for 1.6" @ ISO-100 with B+W 092 IR-Pass Filter and Incandescent Desk Lamp Visible: f/16 for 2" @ ISO-with Baader UV/IR-Cut and Incandescent Desk Lamp Link to comment
colinbm Posted October 23, 2016 Share Posted October 23, 2016 Very nice collection Andrea B) Link to comment
Andy Perrin Posted October 23, 2016 Share Posted October 23, 2016 Yay! They are awesome, Andrea. I knew you'd do something nice with them. Pokeweed is far from the only berry that goes IR-translucent in autumn. I have also had success with chokeweed berries (they grow on a tree) and even some of the nightshades. Link to comment
Andrea B. Posted October 24, 2016 Author Share Posted October 24, 2016 Thank you all !! Link to comment
Guest Posted October 24, 2016 Share Posted October 24, 2016 Very cool! Now I have to go berry hunting too. It may very well be too late in the season, but I'm going to have a look around ASAP. Link to comment
Guest Posted October 24, 2016 Share Posted October 24, 2016 @Andy: I can't seem to find anything on 'chokeweed', specifically. It seems to be a general term for any weed that chokes what it is growing on. Were you referring to some specific kind of chokeweed? Perhaps something local to where you live? Link to comment
Andy Perrin Posted October 24, 2016 Share Posted October 24, 2016 Oh dear, I seem to have mistaken a gardening joke for an ID! Well, I will figure out what the stuff is later. Here are some pictures: http://www.ultraviol...&attach_id=6325 http://www.ultraviol...&attach_id=6324 Link to comment
Andrea B. Posted October 24, 2016 Author Share Posted October 24, 2016 You might be thinking of Chokecherry? Link to comment
Andy Perrin Posted October 24, 2016 Share Posted October 24, 2016 Yep, I think that's it. Link to comment
