Larry, the dance shots are great, your camera and no-light settings are perfect. The sushi shots, on the other hand, not so appertising IR block filters are easy to come by, just ask your friendly Leica pusher. Not cheap, but easy. Ahem On 11/08/2013 8:22 AM, Larry Colen wrote: Cutting

I have to agree with others that the sushi looks revolting. A couple of the shots look like ones that have faded after 15 years in the sun on a cardboard advert in a restaurant window. To me the other shots look like you've documented a Ghoul's Night Out. :-) On Sat, Aug 10, 2013 at 6:22 PM,

are these all with a filter? I thought greens went pink in IR yet the lettuce is clearly still green. very odd. Its not what I would expect at all. I'm so used to seeing extremely processed IR pictures. On Sat, Aug 10, 2013 at 7:21 PM, Larry Colen l...@red4est.com wrote: Excellent! Thanks! On

With an IR filter in front of the lens, and a normal IR cut filter on the sensor, yes foliage turns pink (some reds get through 720nm filters). Everything has a red and pink color to it. When you remove the IR cut filter from the sensor, it is seeing IR and visible at the same time, so colors

so the ultra pink IR shots are taken with the hot filter still in place? I know this is possible, but that exposures are greatly lengthened to the order of minutes sometimes as the cut filter only lets small amounts of IR wavelengths pass. I was under the assumption that shooting with a naked

Larry, have you thought about UV? It should be sensitive to that as well now. I kind of like UV photography. Thanks for sharing these. I look forward to more of your adventures with IR. I think that my older k-7 is going to be fixed that way eventually. On Sat, Aug 10, 2013 at 9:11 PM, Larry
