zampelis Posted May 24, 2018 Share #81 Posted May 24, 2018 Advertisement (gone after registration) Zampelis, An idea for you since your exploring infrared with the Q, you might consider acquiring an infrared light source (torch) and playing around with that at night and for infill during the day. It's likely to be hit-and-miss since you won't be able to see where you're pointing it (unless you're wearing James Bond goggles ) but they used to be available at that online auction site fairly cheaply because there's a large market for them for enhancing infrared security cameras and CCTV. Pete. Thanks for the advice Farnz.. That sound very interesting I will definitely have a look on that! Quote Link to post Share on other sites More sharing options...

pico Posted May 24, 2018 Share #83 Posted May 24, 2018 (edited) I have modest experience in IR, and mainly looked to its ability to see through mist, fog, heavy UV that really messes up what we can see. I have already posted one example of haze cutting and hope to rephotograph the scene in 4x5". Mobility issues hinder that goal, but I hope others here pursue somethings similar. Aside: I happen to have a lot of infrared flashbulbs. They produce an awesome amount of light, and truly IR - we cannot see when they fire. By chance I also have about 150 sheets of Kodak's very last batch of 4x5" High Speed Infrared, frozen, but I have to suspect it is dead, fogged maybe due to what, cosmic rays, useless, so it remains in the freezer, pissing-off my mate when she's looking for just a little more room in there. "Honey?", she asks kindly, "would ye consider getting your own freezer?" Silly, she knows I'm a minimalist! Heck, I move the film to the outside shed in winter, and I remind her only to get this, "So why donecha move yerself with the film out dere. Yer both expired ain't cha"? (Ya gotta imagine an Irish lady who has been commingled with Minnesota accents.) She wonders why I laugh so often.

bags27 Posted May 24, 2018 Share #84 Posted May 24, 2018 . I've used both 720 nm and 850 nm IR-pass filters (and others) and I've always found the contrast available from 850 nm is beyond what's available with a 720 nm filter. I don't do 'faux-infrared' with channel swapping and I prefer the stark whites of foliage, which is probably why 'black' 850 nm filters appeal to me more than 'deep red' 720 nm. I doubt, for instance, that I could have taken the picture below with a 720 nm filter. (I continue to apologise for posting M8 pictures in a Q thread but it's in support of the wider IR theme that this thread has developed into - and I don't have a Q.) Pete. York, May 2018. White House IR.jpg M8 and 21/2.8 Kobalux with Singh-Ray I-Ray 850 nm filter thanks so much for this, Pete, and please don't apologize about non-Q photos: they (you) are an inspiration. BTW, just happened to have ordered an 850 last night. A real cheapie, so maybe just an experiment. 2 Quote Link to post Share on other sites More sharing options...

gbealnz Posted May 26, 2018 Share #88 Posted May 26, 2018 I'd say the hotspot is present, took a couple this afternoon, cold brisk late autumn day, 720Nm filter, used f8, ISO1600. The perfectionist would not be happy with the hot-spot, but right now the ability to do "sorta-infra red" at the screw of a filter is pleasing enough. I'll try differing apertures at some stage, just to see if this has any influence. Gary Welcome, dear visitor!

Marac Posted May 26, 2018 Share #91 Posted May 26, 2018 I love IR, shot it with the M8 using a filter, then I had an old M8 converted (pain in the bottom to do apparently). I have also just sent off my Leica T to be converted by ACS. The current prices on used T's means it is relatively cheap to have a converted Leica. The benefit of having a camera converted is that you can shoot at normal speeds, ISO & F-stop without the need for a tripod. Quote Link to post Share on other sites More sharing options...

Belle123 Posted May 27, 2018 Share #95 Posted May 27, 2018 Thanks for this thread. I have a filter on order to try for my Q. I have a T that I did the conversion on, but curious to see how the Q does with just screw on filter. If it has a hot spot, I don’t think is anything worth worrying about because most of these photos you don’t see it. And, it isn’t like you are burning thru and waisting infrared film, so why not with an inexpensive filter? 2 Quote Link to post Share on other sites More sharing options...
