T44ISKN Posted March 8, 2015 Share #1 Posted March 8, 2015 Advertisement (gone after registration) My first successful attempt at taking an infra-red shot, inspired by a recent talk on this subject at Croxley Camera Club. The Leica M8 with it's extremely thin IR filter, combined with a Hoya R72 filter on the front of the lens, appears to give great results! I shot the image at ISO160 using the "hidden" RAW mode in the camera and then converted to DNG using Arvid's M8RAW2DNG utility. This gave me a low-noise DNG that I could use to boost the image and counteract the loss of light caused by using the R72 infrared filter. Think I pushed the exposure +3EV in Adobe Camera Raw? Other than that, I just used Silver Efex to give me the mono look that I wanted. I'm just using Photshop Elements 11. Link to post Share on other sites More sharing options...

wda Posted March 8, 2015 Share #2 Posted March 8, 2015 Very pleasing result. I use LR which yields very similar results. Did you conduct tests to assess focus-shift? Which lens? Link to post Share on other sites More sharing options...
T44ISKN Posted March 8, 2015 Author Share #3 Posted March 8, 2015 Very pleasing result. I use LR which yields very similar results. Did you conduct tests to assess focus-shift? Which lens? Glad you like it. My first tests came out really blurry until I remembered that you have to compensate for IR focus-shift. I then remembered an article I have read on Luminous Landscape, which recommended using the f/4 marker. With my Elmarit 28mm f/2.8 Asph, this seemed to work nicely.

SuperLeicaPeter Posted March 16, 2015 Share #4 Posted March 16, 2015 Very nice image. Ich have a M8 and also would like to try infrared. Unfortunately (as far as i know) the Hoya R72 filter is not available in 39mm size? Which filter size did you use? And how? Best regards, Peter Link to post Share on other sites More sharing options...
jaapv Posted March 16, 2015 Share #5 Posted March 16, 2015 B&W 092 is identical and available in 39, as is the equivalent Heliopan. Link to post Share on other sites More sharing options...

A member of my camera club lent me a filter in 52mm size. I just hand held this against the front of my lens! It flares a lot if the sun is in the shot, so I'd want to get the right size and use a lens hood. Link to post Share on other sites More sharing options...
wda Posted March 22, 2015 Share #7 Posted March 22, 2015 Advertisement (gone after registration) I use the filter advised by Jaap above. Link to post Share on other sites More sharing options...
T44ISKN Posted March 22, 2015 Author Share #8 Posted March 22, 2015 Today's effort - same settings as described above. Link to post Share on other sites More sharing options...
Lenshacker Posted April 4, 2015 Share #9 Posted April 4, 2015 This is with a Red filter, a B&W 090, about the same as a RED 25A, 5x filter factor. Red channel is visible red, Blue channel is Infrared, and Green channel gets red and infrared. I1015872 by fiftyonepointsix, on Flickr Starting with M8RAW2DNG; Blue and Green channels boosted to same level as Red, then Red and Blue channels are exchanged to give an Infrared Ektachrome look.

Lenshacker Posted April 4, 2015 Share #10 Posted April 4, 2015 I had a chance to take the M8 out to try the new conversion software. 1) This will only work with the M8; 2) this will only work using uncompressed DNG files from M8RAW2DNG. B&W 090 Red filter; Blue and Green channels Equalized with Red; Blue and Red pixels exchanged. I1015873 by fiftyonepointsix, on Flickr All at ISO160, hand-held. I1015961 by fiftyonepointsix, on Flickr 28mm Elmarit, most at F5.6. More here: Link to post Share on other sites More sharing options...
Lenshacker Posted April 5, 2015 Share #11 Posted April 5, 2015 This is with the Orange filter, Blue is picking up Infrared, Green and Red are mostly Visible light. Blue channel boosted, then red/green exchanged. I1016014 by fiftyonepointsix, on Flickr Link to post Share on other sites More sharing options...
Lenshacker Posted April 6, 2015 Share #12 Posted April 6, 2015 Another with the Orange filter. I1016006 by fiftyonepointsix, on Flickr I think this one is fairly close to what IR Ektachrome gave. Link to post Share on other sites More sharing options...
adan Posted April 6, 2015 Share #13 Posted April 6, 2015 If you want the strongest "false-color" foliage, a la Ektachrome EIR shot with a yellow filter, (screaming red foliage, without as much purple cast) you need two pictures, one taken with a pure IR pass filter (no visible light) and one with a yellow filter. (example - real EIR film with yellow filter: https://c2.staticflickr.com/4/3909/15123898936_a43afc7f8a.jpg ) Take the yellow-filter image, and copy: green channel to blue channel red channel to green channel Then copy the IR filtered red channel to the yellow-filtered image red channel. (That's more or less how Kodak did it - intentionally mismatching the spectral sensivity with the dye colors.) Ektachrome EIR shot with NO filter gave the purplish pictures. If you make the blue channel totally empty (black) you get a different palette (second picture). This shot was hand-held, with the channels "hand-aligned" for the central tree trunk. A tripod would do better, obviously, except for moving clouds and such. Welcome, dear visitor!

Lenshacker Posted April 6, 2015 Share #14 Posted April 6, 2015 I have a color filter wheel that is computer controllable. Thiught it would be interesting to use with the M Monochrom to make color images. I could also use it with a set of filters, IR Block, 88a, 87c, to get a color-Infrared effect. I have two full-spectrum converted cameras, one is monochrome.. Link to post Share on other sites More sharing options...
Lenshacker Posted April 11, 2015 Share #15 Posted April 11, 2015 Orange filter- Blue channel is left sensitive to IR. I1016049 by fiftyonepointsix, on Flickr I1016039 by fiftyonepointsix, on Flickr Custom software boosts the Blue and Green channel to match Red, then rotates the color channels in the Color-Filter-Array Tag of the DNG header.

Nordvik Posted June 11, 2015 Share #16 Posted June 11, 2015 I got myself a R72 filter this week. Unfortunately it has been raining every day (and all "summer"), so the pictures could look more infrared-ish, but it was the best I could do. I don't like using Photoshop so I searched for a red/blue channel swap that could work without leaving Lightroom. I found this Camera Profile: http://www.capturemonkey.com/redblueswap-lightroom-profiles Does anyone know any better profile, or could make one? I don't really know which is better, the first one using PS or the second one using the profile i LR. But using the profile is a lot easier and saves disc space. Could someone tell me more about the method behind making the red foliage like with Ektachrome EIR? Welcome, dear visitor!

Nordvik Posted June 30, 2015 Share #17 Posted June 30, 2015 A comparison between M9 and M8 using a IR R72 filter. I used the Camara Profile from my last posting. The M9 needed five more EV (1/8 s vs 2s + 1,0 in LR). M9 first, then M8: Welcome, dear visitor!

satijntje Posted July 2, 2015 Share #18 Posted July 2, 2015 Could we have some IR work on the M8 Facebook group https://www.facebook.com/groups/326047637595813/ That would be great! Others will learn from this, and not everybody is here active on the forum. Thanks in advance John Link to post Share on other sites More sharing options...
