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?

frieri 04-26-2011 06:17

Hi Gil.
As you can see from exif data, I shooted freehand, 1/8 sec. max at f/16.

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.

drew.saunders 04-26-2011 13:05

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.

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.

Roberto, that tree on the mountain with clouds is an awesome photo!

And the mossy tree roots, wow!

peterm1 12-09-2011 11:48

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.

Can an m9 do this? Simply amazing..

johannielscom 12-25-2011 06:06

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...

I don't know, I have never owned a Leica M9.

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.

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