Another one from Tokyo.



I should have some time to try out some WA adapters of various brands/quality today.
I'll update if it turns up anything useful.

Edit : No luck. They were all Vitacon, Emoblitz 0.7x converters. Not good on the edges.
The rest were tele conveters of various brands.

The X3 foveon seems to be really good at modern structures.

No kidding! You've got some great examples. It's a texture monster.


So, I've had a pretty big learning experience tonight. Almost a month ago to the day, I ordered some super-cheap IR filters slow-boat from China. When I say "cheap," I mean it. $23 dollars total for two 950nm filters, and one 760nm. Two are for a lens I don't have yet, but one of the 950nm filters fits on my 50mm macro. The good filters are so crazy expensive that I wanted to try some cheap ones first, just to see if I like the experience.

I've mentioned before that the SD1 has a "dust guard" just behind the lens mount. It's a piece of glass which also acts as an IR filter. Sigma is kind enough to let you remove it in case some dust gets in anyway that you need to clean out. All you have to do is slide it up a bit with a finger and it pops out. It's an Instant, reversible, full-spectrum IR conversion.

My parking lot just got a lot more interesting!




The fact that the SD1 has no live-view is a severe drawback here, as these filters let no visible light through. You have no choice but to shoot blind, and trust the autofocus (which still works with the filter on if the light is strong enough). I don't know if it's just a property of IR photography or the fact that I paid $7 for this filter, but there's a big drop in contrast and resolution. Then again, it could have been a misfocus.

It's still 106 outside, so I did more tests inside. When I tried taking a picture of my Furby (don't judge me) without the filter (full-spectrum), he turned a brilliant shade of red! It's supposed to be black.




This is the same shot with the filter on. Notice the focus shift. I did not change the focus; IR focuses at a different distance than visual light.




If you don't convert to black-and-white, infrared is interpreted as a visible red. Apparently, Furby's fur is highly IR-reflective, but not his plastic face, or his mane, which are all actually the same shade of black.

I also found out that fluorescent lights put out almost zero infrared, while incandescents seem to put out even more IR than they do visible light. In this picture, I have fluorescents in the bedroom and the kitchen, but the dining area between the two has an incandescent bulb. Without the camera's IR filter, you can see this as a flood of magenta. This is why all digital cameras need that IR-blocking filter.




Now, here is the weirdest part of shooting IR with this camera. Here's another filtered IR shot of Furby...



...and here's the out-of-camera JPEG for that same shot. I didn't touch it! This is seriously how the camera's JPEG engine believes the picture should look.




That's not an isolated incident, either. Every single infrared picture I took had a JPEG that looked that weird. Actually, if I left the camera in color mode, it looked even worse. Here's another unedited JPEG (full-spectrum) in all its head-exploding glory:



...and this is from the raw file, edited into sanity:




Additionally, the raw files come out about two stops brighter than the JPEGs. Too weird...

I have a lot to learn.

pinholecam... those shots are excellent! Great colors and detail. Keep them coming

scratchpaddy.... I tried infrared on the DP2m with a Hoya R72 filter and have had no success. Fore some reason the center of all the images has a large diameter hotspot directly in the center. the rest of the image is perfect. In the mean time i removed it and went to the beach (water was 78 with 92 air temps. A dream come true day. Heres some of those pics

Went out to the Canaveral marshlands with the Sigma DP2m.

Man, it really is flat and swampy out there, just like they say! Stunning clouds. That "Vulture Silhouette" is my favorite.

Say, do you do much post on these pictures? Some of them look like they could use some brightening, if I may be so bold.

I'll admit, I beat the crap out of my Sigma's raw files. I get mad at them, and sometimes, they really deserve it.

Here's a couple indoor shots from Phoenix Sky Harbor Airport, Terminal 3. Fun fact: there's also Terminals 2 and 4, but there's no Terminal 1.


This one's at ISO 400!

scratchpaddy... the first pic is my favorite, great colors (and i admit airplane bias). I do very minimal processing on the Sigma pics. These were shot with a polarizer and -.07ev which may may explain the darkness (the sun here is a killer for mid day photography)

Great images everyone. ivoire, love the vulture image. It has a dramatic vibe.

scratchpaddy, very interested in the IR comments. Knew the Sigma DSLRs had a removable filter. Didn't know that they lacked liveview. Bummer. They should be able to do liveview. The DPs do it with the same sensor.




This is my front yard during the midwest USA floods this year. About 30 ft from the house, which is on much higher ground. Sigma DP1Merrill.
thanks

Nice shots!
You really push the camera with indoor shots like these.

@barondla , glad to hear your house is high and dry! Let's hope it doesn't get much worse for you folks.

@pinholecam , thanks! This camera really is a blast from the past. No live view, no video, crappy low-res screen, and when was the last time you could say ISO 400 was pushing it?

Here's to pushing it some more.












But no further. Abandoned mines are creepy.

These are some fantastic images! I've been looking for good sub-24mm primes for my Pentax kit, but I'm often dissatisfied with the results on landscapes. Now I'm considering a Sigma DP1M for UWA street and landscape photography, and let my K-mount gear start with my Zeiss 35/2.

Has anyone tried the same? Thanks!

Have you tried the K24/2.8?













Otherwise, I liked the DP1m (landscapes) very much combined with a Q7 (streets).
I have some shots with the DP1m in this thread and some Q7 ones here:

I do things the other way around. For a while, on hikes, I used a K-5 and Vivitar 13mm (which is an amazing lens for ~$300, BTW) for the really wide stuff, and the DP2M for the somewhat tighter angles. Now, I use the SD1M (usually with the 12-24 ii) for anything with enough light or enough time to get a longer exposure, and the DP2M is the carry-around-everywhere camera. The Pentax still gets the action/dark shots, but it stays home on hikes.

Just keep in mind that if you go beyond ISO 800, the resolution advantage these cameras have disappears.

You mentioned street photography. The Foveon is amazing for architecture, but not so much for people unless you like a hard, gritty look, or have lighting conditions good enough for ISO 200 or less and don't need to pull any shadows. I'm no street photographer, but I do like taking pictures of city architecture.

SD1M, 12-24 II @12mm, f/6.3, ISO 200


(BTW, you can click almost any of my pictures for full-res)
