smokysun Posted February 1, 2010 Share #1 Posted February 1, 2010 Advertisement (gone after registration) my question is about manipulation. i've a d-lux 2 modified for infrared. these are not manipulated to make them look like something different. (and some are with a modified canon g6.) do you think they'd be automatically disqualified? thanks for your input. wayne wayne pease's Photo Galleries at pbase.com entry 2: childhood regained Photo Gallery by wayne pease at pbase.com entry 3: thursday eve farmer's market Photo Gallery by wayne pease at pbase.com entry 4: sunday on the river Photo Gallery by wayne pease at pbase.com entry 5: place of my earliest memories Photo Gallery by wayne pease at pbase.com entry 6. http://www.pbase.com/wwp/entry6 Link to post Share on other sites More sharing options...

griffster Posted February 1, 2010 Share #2 Posted February 1, 2010 Dunno nuthin about the rules, but those are some awesome photos! I always thought that for IR photography you needed rather slow shutter speeds, yours almost seem like snapshots. How do you do it? Link to post Share on other sites More sharing options...
brucek Posted February 1, 2010 Share #3 Posted February 1, 2010 I always thought that for IR photography you needed rather slow shutter speeds, yours almost seem like snapshots. How do you do it? You can get a camera modified for IR use by having its hot mirror (or IR) filter removed from in front of the CCD. This makes the camera incredibly sensitive to IR and even lets you compose right on the LCD. And as you've noticed the shutter speeds get fast enough where hand holding the camera is a definite possibility. This is even feasible with the M8 if you're willing to crank the ISO up high enough.

smokysun Posted February 1, 2010 Author Share #4 Posted February 1, 2010 thanks, griffster. yes, the modified cameras can shoot in most lights hand-held. alas, for the contest, i think they'll see them as manipulated, even though they come from the camera very much the way you see them, no more manipulated than most photos. wayne wayne pease's Photo Galleries at pbase.com Link to post Share on other sites More sharing options...

This is even feasible with the M8 if you're willing to crank the ISO up high enough. No need to crank up the ISO (and pay the heavy noise penalty in IR). It's easy enough at ISO 160 to get fast enough shutter speed for hand holding even with a 28/2.8 Elmarit asph wide open, which is a particularly good lens for IR imho. Estimating focus at close distances needs some practice but for landscapes, for example, there's no problem. Pete. Link to post Share on other sites More sharing options...
farnz Posted February 1, 2010 Share #6 Posted February 1, 2010 ... these are not manipulated to make them look like something different. ... With the greatest respect, Wayne, it looks to me like your 'Childhood Regained' shots - as gorgeous as they are - have been manipulated to give 'faux colour' IR, which involves swapping colour channels over in RGB. If you don't consider this manipulation then fair enough but you might that the Barnack Prize panel has a different opinion. Why not just 'suck it and see'? Pete.

smokysun Posted February 1, 2010 Author Share #7 Posted February 1, 2010 Advertisement (gone after registration) thanks, pete. they were actually shot with the d-lux 2 converted to ir. but i can't remember how i did process the files. didn't seem all that extreme. unfortunately, though people like these photos, everybody seems to agree they'd be rejected in this particular case. thanks much for looking and the comments. wayne wayne pease's Photo Galleries at pbase.com Link to post Share on other sites More sharing options...
griffster Posted February 2, 2010 Share #8 Posted February 2, 2010 Wayne, please excuse me for going off topic, but I tried some IR photography with my D-lux4 using an IR pass filter (72nm). I need really long exposures, but in the end I get a spot in the middle, which is probably my aperture. With max aperture it's larger but less evident. Smaller apertures show a clear lighter colored hexagonal dot in the center. A friend of mine said this might be the reflection of the aperture on the filter. Do you have any idea what this might be?

stunsworth Posted February 2, 2010 Share #9 Posted February 2, 2010 Some lenses have a "hot spot" in the middle of the photograph when taking IR images. I believe it's due to the lens design. Link to post Share on other sites More sharing options...
jankap Posted February 2, 2010 Share #10 Posted February 2, 2010 Wayne Especially the series "childhood regained" has a super atmosphere. Was it necessary to install another filter into the camera? I would like to start an experiment with an old digicam (bridge type) too. Jan Link to post Share on other sites More sharing options...
smokysun Posted February 2, 2010 Author Share #11 Posted February 2, 2010 griffster, i think steve is right. i didn't have much luck with regular digicams and filters plus long exposers. that's why i turned to modified cameras. jan, no extra filter, though i did do some post-processing. i had the camera modified at Precision Camera - Infrared Digital Camera Conversion Service their prices were a lot cheaper than the two major companies, maxmax and lifepixel. very good service. if mark, their service manager is still there, give him a call. he was very helpful. i simply don't think even an m8 can do the job the way a modified can. here's an example with the 5d converted: guardian angel Photo Gallery by wayne pease at pbase.com best, wayne wayne pease's Photo Galleries at pbase.com Link to post Share on other sites More sharing options...
farnz Posted February 2, 2010 Share #12 Posted February 2, 2010 ... i simply don't think even an m8 can do the job the way a modified can. Wayne, I'm intrigued: since the 5D is an SLD and you're composing through the lens which has an IR-pass (visible light blocking) filter how do you compose and focus if you can't see anything? Or do you leave the filter off for composing and focussing and replace it to take the shot, in which case won't the point of focus shift owing to the shorter wavelength of the IR band? (Obviously the M8 doesn't have this problem.) Pete. Link to post Share on other sites More sharing options...
smokysun Posted February 3, 2010 Author Share #13 Posted February 3, 2010 hi pete, the 5d converted by maxmax. no problem seeing. when cameras converted, they adjust the focus to fit. wayne wayne pease's Photo Galleries at pbase.com Link to post Share on other sites More sharing options...
noah_addis Posted February 3, 2010 Share #14 Posted February 3, 2010 I may be wrong but I think you're only allowed one entry, no? Anyway, I'd say the color ones do look manipulated, even if they did come that way out of the camera. The B&W ones look more like traditional IR work in my opinion. In any event, it's free to enter, just give it a try... Link to post Share on other sites More sharing options...
smokysun Posted February 3, 2010 Author Share #15 Posted February 3, 2010 thanks, noah. yes, you're allowed only one entry (plenty of them already with this stipulation!) i think i'll go with a non-ir one i didn't post here before: entry 1: the actors Photo Gallery by wayne pease at pbase.com i've been working up more photos from that shoot and have lots to choose from. thanks much for looking. really appreciated. wayne wayne pease's Photo Galleries at pbase.com Link to post Share on other sites More sharing options...

Thanks for your help. By the way, did you see the information about the FLIR H-324? This technic (thermal infrared) is coming down from astronomic prices and is entering an interesting region.

smokysun Posted February 4, 2010 Author Share #17 Posted February 4, 2010 thanks, jan. no hadn't heard about the thermal. that will be interesting. the nik plugin color efx has a faux effect. however, i suspect the real thing more interesting. best, wayne wayne pease's Photo Galleries at pbase.com Link to post Share on other sites More sharing options...
smokysun Posted February 6, 2010 Author Share #18 Posted February 6, 2010 i've had to go with the 5d shots, but since this a leica prize i figure it's fair to ask for more help. i've worked up a bunch of the rehearsal shots and would like feedback on the ten strongest. i'd like to show a contrast between backstage prep and the onstage 'reality'. none of these posed for the camera, all shot while the actors in motion. entry 1: the dress rehearsal Photo Gallery by wayne pease at pbase.com thanks again for your curatorial help! wayne wayne pease's Photo Galleries at pbase.com Link to post Share on other sites More sharing options...
