IR X-Ray filters?!

[A. Dale]

I've been seeing a lot of these IR photos (took me about a day to even guess that IR stood for, haha) and they look really cool. I'm interested in learning more about the technique and was looking online. Do these things really see through thin materials or is that just certain types?

Ya know, I was one of those kids who always wanted to buy the "X-Ray Vision Glasses" from gag catalogs. Heh.

On a more serious note, how much do IR filters run and where could I get one for a reasonable price/service online? My F828 is coming in next Wednesday or so.

Can't wait!

Hi,

The most complete IR filter range I know, with transmitance diagrams and samples with the different IR filters is at http://www.maxmax.com

Hope this helps.

this is a serious note as this is why Sony cripple the night mode, because of people who use the camera in that matter (

For that, all users pay the price.

I don't even think it's worth it..you see more "skin" at the beach! Also you can try the internet..it is loaded with totaly naked ladies.

Just purchased an 828 with the intention of using it for IR photography, and it's far and away the hottest camera I've ever tried for this. Once that IR cut filter is out of the way (in the "nightshot" mode), it's possible to get good exposures with every IR filter I have, in fact all the way down to 1000nm. It's a shame that Sony didn't exploit this IR capability instead of crippling it with a fixed f-stop and shutter--ridiculous! Yes, I've seen some photos taken with the older non-crippled cameras, and it wasn't anything to get excited about. Under the hot sun, black nylon becomes somewhat translucent to near-IR, but so what? Is that sillyness worth throwing away perhaps the greatest virtue this camera has?

Fortunately it's possible to find workarounds for the deliberate attempts that Sony has made to prevent the use of the "nightshot" mode during daylight. The most common complaint when using the usual Hoya R72 filter is that highlights become blown out, and I also see this, even on an overcast day. One solution is simple, but fairly expensive--get a couple additional IR filters having deeper cutoff points. Perfect exposures occurred by simply changing from the R72 (720nm) to the RM90 (900nm), and with the same lighting conditions underexposure became evident with the RM100 (1000nm), but perhaps it might provide correct results with direct sun. If the R72 is all you have available, then ND filters (4X, 8X) may be added, or if you can find a couple linear polarizers they can be rotated with respect to each other in order to achieve any degree of attenuation.

Perhaps even more exciting is the idea of using the 828 for ultraviolet photography. Some preliminary tests of mine today with a Rolyn U-360 filter stacked with a hot-mirror show a fair degree of sensitivity. Guess when and if the sun breaks through we'll find out for sure.

That is really unfortunate. I'd never use it to look through anyones clothing, I just think it make for a cool effect if you were to set something up draped in cloth.

Maybe you could pick up a secondhand 707/717, takes the lens assembly apart and remove the IR cut filter? The camera would think that its in normal mode all the time and you would have access to all the manual controls.

Hi,

The people at MaxMax are providing this kind of services. Even they provide an external IR filter to keep your camera working for standard shooting after the modification.

I'd like to see some UV samples when you get them!
