Those are really good!

I should throw the IR filter on the M8 and try it out. The color correction on the Summicron is good enough to use wide-open without need to refocus.

Does anyone offer a service to replace the IR absorbing glass on the M8 with a clear filter, or visible-absorbtion filter? I had an Olympus EP2 converted to full-spectrum.

What's the filter factor of B+W 092, tripod a necessity?

Hi Gil.
As you can see from exif data, I shooted freehand, 1/8 sec. max at f/16.
For more details (in italian): http://www.robertofrieri.net/20110423T140814.html

Hi Robert, not many can handhold at that speed specially with high caffeine in our bloodstream. Great shots you have there.

I do like these IR M8 threads, each time I look at them I come just a little closer to buying a digital Leica, I just need to find one at the right price and that may be difficult.

I've wondered what an M8 would do with an IR-pass filter instead of the IR/UV cut filter, so these are very informative, and well done. Maybe if the prices of M8's become reasonable (relatively speaking) I'll get one just for IR. I have a Hoya R72 filter and the right step-up rings to use it for my various Leica and CV lenses.

If you were getting 1/8 at f/16 in sunshine with the camera set to ISO 160, that gets an ISO of about 8 through the B+W filter (4-1/3 stop filter factor or thereabouts), which is a huge improvement over the ISO of 1 or so that I get with Efke IR820 and the R72 filter.

hey guys, actually i did a few test shot while i was having my lunch the other guy with a hoya R72 on my M8 .. thought you guys might be interested. i did color swap, auto color and brightness/contrast adjustment to the images in Photoshop.

The source image look like this.



and this are the edited ones

I was shooting quite a bit of IR up until I sold my M8. I liked to shoot wide open and push the iso up to 640 so I could use faster shutter speeds.
This one was shot at 1/60 at f4.5 iso 640. I can't get any where near that with my M9.

Super pic, reminds me of Counter Strike on-line game for some reason. M8 is the bomb for infrared!

Very interesting thread - some supurb pictures - great inspiration.
Took my first IR pic last week and I'm in the learning mode.
Used an IR850 filter, ISO 80, 1/4 sec at f3.5 - no tripod but jammed against window frame - I've a long way to go to get to this standard.

Lovely pictures! I tried infrared, using a cheap filter on a Nokton 50 on my M8.

These are gorgeous pictures! Has anyone used an M8 and IR to do "scientific" or "practical" work, like looking for heat loss in a building? I have some heating issues with my new house, and thought it would be a way to diagnose. I know that for checking the hot water tubes under the floor they use an IR camera, but it is not clear to me that the M8 with filter will work in that application, or which filter I ought to get.

For heat testing, it looks like I ought to get the B&W 93 instead of the 92, but it wouldn't be as useful for picture taking.

Any assistance is much appreciated.

I need some info on the technique for this. I have an old deep red Leica IR filter (39mm) for my Summicron. And I have an M8. But what from there? I tried shooting some shots in RAW with the IR filter thinking I could convert to BW after (M8 jpgs being notoriously poor) but I could not get a good IR look no matter what I tried. Does this mean you have to shoot jpgs and set the camera to its monochrome mode?

Hi Peter,
I usually shot IR pictures during spring or summer, with a powerful sun light.
You need an infrared filter (like B+W 092-093 or Hoya R72).
I prefer low ISO and longer exposure time.
I convert the M8 raw file using Capture One 6.

Sorry for my poor english.

I shot this on my M9 to compare with the shot earlier in this thread shot with same lens and filter on an M8. Similar results although the exposure went from 1/60th to 1 sec.

The IR on the M8 would be the one reason I would consider buying one after all.
Switched back from M8 to M3 and M2 but those IR shots are alien and that happens to be something I really like in my work, those out-of-this-world aspects of prints...

Ok, that's a starting point (in my opinion).
I think you need some more post-processing.
For example, snow and clouds should be white and the sky quite black.
Just another indication, if useful: prefer broadleaf (tree/forest) than conifer.
(Sorry for my poor english).

Thanks for the tips. I did not do much post processing, as I really am not much for it. It turns out that Aperture has an IR preset, which I used, then tweaked a bit to get what I posted. Any suggestions of good books or web pages to learn a bit more about this stuff?

As to broadleaf vs. conifer, at this time of year all the broad leaves are lying on the ground around here! Not to mention that 90% plus of the trees around here are Pine trees of some sort. But in a couple of months, I can take a short road trip and try the IR filter on some Aspen.

Finally, don't worry about your English! It sure beats my Italian.

Grazie!

These are fantastic, I had no idea you could do this with an M8. Now I am even more excited about this camera of mine that I am trying to figure out. I love IR stuff and had no idea my camera could do this. Can someone point me to a tutorial or something showing the process. I can order a filter to shoot with but then???? I dont have Capture 1, can I use something else or will any Raw editor work?? More info on how to do this please!!!!

It's fairly simple with an M8
Get yourself a Hoya r72 filter to fit your lens. With my M8 I mostly used a cv15mm with a 52mm filter. I shot wide open, auto exsposure, auto ISO set so the shutter never dropped below 1/60th and the ISO never above 640. Focus set shy of infinity. I have a set on flickr here all shot handheld.

I post processed with camera raw to desaturate and generally crank the contrast and clarity.

Now I have an M9 and good results are much harder to come by. Definitely no more hand held auto exposure shots.

Some IR shots from my last portfolio dedicated to the archeological area of Fiavè (Trentino - Italy), a protected biotope which has remained unspoilt and it hosts the remains of pile-dwelling structures dating back to 2300 b.C.
The portfolio is made of 15 images: http://www.robertofrieri.net/biotope.html
Hope you like it.

Lancer. Did you get any info?
I did some I/R when I had an M8, but since owning the M9, haven't really tried any.
I am about (this weekend) to swap back the M8 and just own that, so will be tucking into more and more I/R.
In my case I just shot at about 1/30th at about f5.6 or so, using ISO640. I bought a cheapish I/R filter from * bay, and away I went.
Of course it depends on a multitude of things, filter, day, foliage etc, but just get a filter and try (PM me if you need a lead on the filter to try etc).
Processing? I open the image in LR and go from there, normally making it greyscale at the first and tweaking from there.
Just try it, if there was ever a reason to have an M8 it is I/R, no other camera I have used has allowed handheld I/R before.

I just started to try IR with my M8. I had a Hoya 72 filter which is pretty much the same transmissibility as the B&W 092. I bought the filter to use on my Nikon D300 without realizing that the sensor's IR cut filter pretty much makes the camera useless with an IR filter on the lens. Fortunately, the M8 has a very weak sensor cut filter and it can do IR photography pretty well.
Anyway, after reading some threads, I simply used the sunny 16 rule: ISO 160 at f16 which gives a shutter swpeed of 1/160 sec.. I then multiplied 1/160 sec by the filter factor (20-40) by splitting the difference at 30. The result was 1/4 second @f16 with ISO 160 on a sunny day. The results came out using my M8 with the Hoya 72 filter great on the first try.

I suggest that in Lightroom, applying the preset filter for Infrared to get rid of the reddish cast, bumping up the contrast to +70, and toning down the highlights by 20. You may then want to apply high pass sharpening to the result with the slider set at 30 to 50. I found that the M8 is a bit noisy shooting IR even at ISO160 but is rather grain like. Any good noise plug-in can take care of that. Accurate focus is a bit difficult to be right on due to the difference between IR wave length and visible light wave length so I'll have to play with that some. But the DOF @ f16 is pretty forgiving.

I'm just starting with IR, but I think these parameters seem to be a good starting point.

The exposure meter on the M8 will measure correctly when using an IR filter.
Depending on the lens, it is often correct to use the DOF scale 5.6 mark for scale focussing. And focus-bracket. To get the B&W balance sand contrast right just hit the image with the color balance eyedropper tool and take it from there with curves.

Sounds like a simpler approach. Here is another approach from a member of the Leica users forum known as pinspot:
"..Do, do get an IR filter, Heloipan do a good range of them at a fair price
Set the colour temp to 2000, ISO to 320, shoot in RAW - and you've got digital IR photography - handheld on a good bright day - dead easy...."


I'll try them all and thanks for the many inputs.

An IR novice's first attempt

I just started to try IR with my M8. I had a Hoya 72 filter which is pretty much the same transmissibility as the B&W 092. I bought the filter several years ago to use on my Nikon D300 without realizing that the Nikon sensor's IR cut filter pretty much makes the camera useless with an IR filter on the lens. Fortunately, the M8 has a very weak sensor cut filter and it can do IR photography pretty well.
Anyway, after reading some threads, I simply used the sunny 16 rule: ISO 160 at f16 which gives a shutter speed of 1/160 sec.. I then multiplied 1/160 sec by the filter factor (20-40) by splitting the difference at 30. The result was 1/4 second @f16 with ISO 160 on a sunny day. The results came out using my M8 with the Hoya 72 filter great on the first try.

You may then want to apply high pass sharpening in Photoshop to the result with the slider set at 30 to 50. I found that the M8 is a bit noisy shooting IR even at ISO160 but is rather grain like and not too bad. Any good noise plug-in can take care of that. Accurate focus is a bit difficult to be right on due to the difference between IR wave length and visible light wave length so I'll have to play with that some. But the DOF @ f16 is pretty forgiving.

I'm just starting with IR, but I think these parameters seem to be a good starting point for me. The 52 mm Nikon sized 72 filter fit my Nokton f1.2 35mm lens so that is what I used to experiment. I have now ordered a 39mm B&W 092 filter for my more standard Leica lenses.

Well this is my first attempt with the M8. Looks kinda weird: I don't think I did it right. I'll check out some tutorials on the web.

Snowbuzz,
I like it very much. Nice mood. I tried several methods and the one I included in my previous comment:

Set the "..color temp to 2000, ISO to 320, shoot in RAW - and you've got digital IR photography - handheld on a good bright day - dead easy...."

worked very well. Better detail than my previous method and dead simple. I also used the f5.6 mark as the index focusing mark and got pretty sharp focus.
