I like having the extra possible color spaces to work with when I want
It's gay and retarded.
I really like IR, it’s a fun shooting experience made much easier now that i have a rangefinder. I’ve been shooting IR for several years now, and only now I’m I really starting to «get» it. Pyrocat has been my developer of choice for it now. However I only like B&W IR, i think films like aerochrome and the full spectrum digital stuff is kind of silly unless you use the colors for a reason. When I say this I’m reminded of the photographer who shot child soldiers in Africa on aerochrome.
>>4493043Norway in winter isn’t the best time to use IR, but nevertheless I continue. This was some weird weather. Fog rolling in with intermittent sun.
>>4493043
>>4493043rz67, 6 second exposure
>>4493043Wow another pyro user. Pyrocat MC is my go to these days. Did you mix your own? Are you using pyrocat HD?
>>4493052i’m a pleb so i use this
>>4493057Nice. 510 pyro is better for smaller negatives and a good "beginner" pyro anyways. If stained fixer bothers you pyrocat MC does not turn my TF4 fixer piss yellow.It's quite easy to mix and super inexpensive if you ever decide to give it a shot. The only pain is getting some of the chemicals to dissolve fully in the propylene glycol if you choose to use it for shelf stability. Photographers formulary has all the raw chems for it.
>>4493043censor because blue board but earlier when i was using IR I found some grow bulbs that emit the frequencies of light IR is especially sensitive to. made for some of my favorite images like picrel
>>4493033Takes one to know one
A DIY full spectrum conversion is a great way to get some use out of an older camera
I bought 3 Rolls of IR sensitve BW film because just putting that in my camera is easier than converting my DSLR.Unfortunately I fucked up when buying the filter so all of the IR shots came out blank. But I still got two rolls left and I'm waiting for trees to grow leaves again and sunny days being more common to try again
>>4493564Be careful my dude, a lot of automatic SLRs use a infrared light as a part of the film advance mechanisim which can fog or outright blank your IR film.Normally I hear about fogging but it's not impossible this happened to you and it was extra bad.
>>4493588The camera is fully mechanical so no worries there.The film looks like regular BW film if you use it without a filter, so luckily I took every picture twice (to compare if I got the exposure right and get a better feel for the effect mostly) and only the ones with the filter came out blank, because I got one with the wrong wavelength.The regular photos like picrel are fine, so the the roll wasn't completely wasted.But I do want to caution people how sensitive this film is. I got what looks like quite a bit of light leaks well into the first few frames and I suspect it's just from handling the canister outside on a sunny day.
>>4493613>I got what looks like quite a bit of light leaks well into the first few frames and I suspect it's just from handling the canister outside on a sunny day.picrelYou can see there is some leakage at the beginning of the film as well as around the sprocket holes.Next time I'll definitely make sure to load the film at home or at least find a nice shady spot
>>4493613>>4493614 At least with visible light the image quality looks great. Just to make sure, did you remember to increase the exposure time accordingly to compensate for the filter light loss? Which filter did you use?
>>4493613what film was it you were actually using? The rollei 35mm stuff?
>>4493655>>4493655I used some cheap noname 850nm Filter from China, but the Film (Rollei Infrared) only goes to 750nm, so no idea how I managed to mess that up.I couldn't find any solid numbers on how much I needed to adjust the exposure for the filter so I think I went for like 5 or 6 stops of overexposure.It's honestly just really fun to shoot to, because it's such a deliberate process, of setting up your tripod, composing the image, dialing in your setting, putting in on the filter. Really relaxing.
>>4493614Classic light piping, yes it is from handling in daylight.Not really related to it being IR film, it's because Agfa uses clear PET base instead of acetate
>>4493812I see. I'm an inexperienced Film Photographer and that was like my 5th roll ever. Didn't even know handling in daylight could be an issue before then
i only know digital.ir at the sensor. but i want more. what are the limits?
>>4494099>what are the limits?They don't make the "good" IR film (HIE) anymore, which could get 900nm. Digital will get you 800+nm, current production films aviphot and SFX will get you around 720nm.Take the microbolometer pill, 7500+nm
>>4493013Do you just need a lens filter for this on digital cameras?
Direct sunlight, incandescent or xenon flash light is fine for IT but normal led or fluorescent does not have enough IR. Vintage lenses which have the IR focusing mark are designed to work with IR, but modern lenses usually have not.For full spectrum, chromatic aberration can be a problem on any lens.(Modded Canon A810, W12 minus blue filter, hue +120.)
>>4494121(Not OP)Slap a chinkexpress IR pass (720nm or more) filter on digital camera, few seconds exposure for subjects in direct sunlight depending of the camera builtin IR cut filter. Optionally first take a photo of grass in sunlight thru IR filter and set custom white balance in camera by that.Results will not be great but it's a start.
>>4494134>>4494132I suppose even if its not that accurate to what it "should look like" it might be a cool effect for photos.
>>4494243Modded camera + W12 + RGB->BRG channel swap is digital imitation of Aerochrome false color film. Visible light blocking IR pass + white balance on grass is almost monochrome but channel swap still improves the look.
>>4494267Can I do this with a non-retarded amount of money?
>>4494275If I remember right the camera I modded and shot that with cost 40€ in local shop new. (Canon PowerShit A800.) I replaced the IR cut filter with one cut from a polyester 780nm IR pass filter which cost around 30€ + postage.Low end PowerShots had thin IR cut filter which could be tossed or replaced. Cameras with a thick builtin filter (low end Nikons?) may need a clear glass replacement to focus properly.
>>4494104>320x240pxdropped
>>4494306>>4494275amazon lists IR filters for pretty cheap. like under 30$ usd
>>4494558You need more than just a screw on filter anon
>>4494275i think you can find some modded cameras for cheap on ebay.
>>4494275yeah rip the hot filter off your camera and buy a 720 filter, doneif you don't understand electronics or how cameras work you will absolutely fuck up your camera, though.
>>4493564shooting film in the infrared spectrum is not easier than converting a DSLR if you factor in time spent unwittingly fucking up entire rolls of film and waiting on it
>>4494306>Cameras with a thick builtin filter (low end Nikons?) may need a clear glass replacement to focus properly.if you print out a focus calibration doohickey and just torque the screws on the sensor cover correctly based on that before putting it back together, it obviates the headache of sticking something back in the place of the hot filterI've done three conversions now and recalibrating focus is a must if you want to retain infinity focus because you will unwittingly shift random shit around and over/undertorque certain things.
>>4497878Can't comment on that until next summer.Though DSLR conversion seems pricey and I'm not sure if I would want to do it myself
>>4497884>DSLR conversion seems pricey and I'm not sure if I would want to do it myselfdepending on the camera, it's braindead simple if you have ever completed fundamental childhood technical tasks like turning a disposable camera into a taser or replacing a part in your laptopthe nikon DX0 and D5X00 series are retarded simple to the point where you take five screws off, open the body, then take another four screws off to yank the vis-pass filter off the sensor, then put it all back together. You don't even have to fuck with the focusing if you don't really care, since the D90 and all D5X00 cameras have live view so autofocus and exposure preview will still work even with a screw-on filter.
I've dabbled in IR a small amount.
>>4493013I don't see the point desu
>>4494560I use unmodified 5d with an Amazon filter and tripod for IR and I think it can be done on the cheap. I was shooting with ND filter prior to IR which I found helpful.
>>4498110>I use unmodified 5d with an Amazon filter and tripod for IR and I think it can be done on the cheap. I was shooting with ND filter prior to IR which I found helpful.What sort of shutter speed and aperture do you need to use?
>>4497950ah yesintimate rocks
>>4498173These tend to be in the ballpark of F4, iso 800, 5-15 second exposures depending on the conditions.
>>4498110Thats pretty cool. A 5D 1? I want to do it on my A7s 1 which doesn't get use anymore... Built in filter is too strong.
>>44982125Dm4 I got used. Camera before that broke when tripod tipped over into a rocky stream.
>>4498211Do you have to use long exposure when shooting unmodified?
>>4498219Yes very long. In bright sunlight I shoot about 5-10 seconds, and sometimes need to shoot significantly longer for instance in partly shaded compositions. IR is great because it works best in harsh daylight and works great on unmodified camera and easy to get started if you’re already interested in long exposure photography.
