Another M8 Infrared shot


Recommended Posts

Nick,

 

I like it very much too. Might I respectfully suggest compensating for the vignetting in Lightroom? I find that many of my lenses produce the same broad vignetting but I've saved a Lightroom preset that applies de-vignetting, which makes a considerable difference. :)

 

Pete.

Nick - this shot suggests a whole album's worth of late mornings on the grand tour a generation or so ago (the contemporary motorcycle helmet notwithstanding); good example of a foto inviting lots of narratives, apart from being interesting in itself.

Hi--figured I'd hop in.

 

Shooting IR with the B+W 93 is a focusing challenge. (My filter came Friday.) Six-to-seven stops of light loss (plus focus shift) make life interesting. I've been enjoying shooting IR shots in a testing mode. What I've found to be cool is the restrictions it puts on the photography, which is forcing me to work a bit harder. I've been post-processing the photos in Aperture (as "color" shots), and then pushing them to TrueGrain for black and white work--the results have been excellent. (Subjects will improve. I'm just testing process and workflow at the moment.)

 

Just a quick sample shot attached.

 

A few more are here (IR w/B+W 93, processed with Aperture then pushed to TrueGrain):

Thanks,

Will

I've been thinking of IR photography with the M8 for a bit and had purchased a Lee 87 polyester filter. I hand held the filter over the lens and let her go.

 

When I saw this thread I had the motivation to take the plunge... many thanks.

 

The first image was hand-held and pushed to grain with an ISO of 1250. It was a very windy day... the next image was taken, a day later, from a tripod with an ISO of 160. Both shot with the CV 40 1.4. The first wide open and the second at f 8. Conversion in LR.

 

Its a tough way of shooting but now I move around town I can almost 'see' in IR. These are not great photographs but they were fun to make.

Anyone did compare the result of B/W 092 and 093 filter ?

 

Can't make the comparison you're requesting. But. . . I can say that the 093 completely blocks visible light, showing IR light only.

 

Here are some additional observations:

* Six to seven stops of light loss.

* In-camera metering seems to work OK!

* Infinity Focus: With a 35 Summicron ASPH (at f/2), "infinity" (e.g., closer horizons in the 200-400 ft. range) can be set at about the middle of the "2" in the "12" focus ring marking.

* Other Focus: Focus bracketing. Sure feels like I will be able to focus through the RF and then misalign the patch by X to always hit focus dead-on. Just need to internalize the offset through experience.

* Speed: With reasonable sunlight, 1/30th at ISO 320. Bright sunlight 1/125 at ISO 320. Manually set indoors (lots of sunlight) to 1/30th at ISO 320 and pushed about two stops in Aperture--looks OK.

* Color: Comes out in shades of purple. A-OK. Post-process with Aperture to adjust exposure, tones, etc., and then TrueGrain to get B&W.

 

IR has been fun. I like the "shot by moonlight" quality IR shooting seems to give. I'll figure out other interesting stuff as I go. A few samples here: Infrared - a photoset on Flickr (More in the pipeline.)

Today I went out and shot some IR at a very often shot place called Tres Palmas.

 

I used my hand held Lee 87 filter and shot on a tripod at f 22 using my elmarit 28 2.8.

 

I noticed as image 1 indicates that the aperature seems to have let in more light than the rest of the frame. I had not seen this before.

 

The second image is one that I croped down and adjusted to my liking.

Tollie: The "center burn"--or bright "hotspots" on certain images was brought up by farnz in another thread:

 

I have noticed that hotspots vary with aperture. At small apertures they appear smaller and brighter and wide open they appear dimmer but larger. I have a pet theory that as the aperture is stopped down it masks the areas at the edges of the lens and the cause of the hotspot is channelled through the centre of the lens, and vice versa. I shoot wide open and only experience some vignetting, which can be easily equalised in LR.

 

I haven't experienced any hotspots yet--but I'm shooting between f/2.0 and f/5.6.

 

Thanks,

Will

Hey Will,

 

many thanks... this forum is a world of knowledge...

 

This is the first go at shooting with IR stopped down... the rest have been f8 or just wide open. In these cases I had some dark spots... like vingnetting but not in the corners... but this is the first I've seen of the hot spot.

Hot spots when shooting IR with a pass filter seem to be lens specific and may be caused by internal reflections. You will find lists of "good" and "bad" lenses for various systems on the net and perhaps even in this forum for M lenses.

Here are my first attempts at IR with a 21/2.8 ASPH and a BW 093 filter. The focus is a bit challenging but it seems to be infinity at 5/6 feet.
