Im still pretty new to photography as an art. I was wondering how people capture infrared exposures. I have a Pentax *ist DL. Is there a certain filter, or is that camera just not capable of infrared?

I recently bought a converted Canon D60, for taking IR-only shots. There's a growing number of cameras that can be so converted. The advantage of doing it this way is that you can capture images at the "normal" camera exposure settings, whereas a filter will generally mean much slower exposure times - necessitating a tripod in most cases.

My camera was converted by irdigital.net for $350, but there are other vendors who may do it for less. (Can someone else chime in here with URLs?)

Take a look at my portfolio pics for my initial set of black & white samples. I also have many colored IR shots that I haven't had a chance to upload yet. I'm still "feeling my way" with this, ...and slowly improving (I hope), but it's definitely fun!!

The standard test is to take a pic or two in the dark with the remote control of your TV or something pointed towards the camera. If you see something, you have IR sensitivity.

However, you may need a longer exposure as the sensitivity might be fairly low.

Once you know what it can do, you can use something called a Hoya 72 IR filter.

With threaded filters, I usually get one large one and a step-down ring, but this might be one case where you only use one lens generally with it.... your call.

I believe that I read somewhere that the Sony sensor that is in the Nikon D70/Pentax/Konica Minolta 7D/5D does have pretty decent IR sensitivity, but again, you might need 20-30 seconds for it to show up.

Another person posted about this and didn't find any results for his 5D, but got results from his P&S cam... He didn't post exposure time, so I don't know if this was because of a more sensitive P&S cam and insufficient time on his DSLR test shots.

I just picked up a 52mm Hoya 72rm filter. I can use it on my 50mm 1.8 lens for my digital rebel but the shutter speed ends up between 8 and 30 seconds depending on the light. I also have to set up my shot before I put the filter on so it becomes a bit of a pain. I just purchased an Olympus 2020z from Philup which works great for IR. Great sensor, can see the pic on the LCD before I shoot and I dont have to remove the filter or really use a tripod a sthe shutter speed is pretty quick. You can find them on ebay for between $100 and $150. The problem with them is that they are only 2.1mp. My experience is limited overall. I believe Marbo is the main man when it comes to IR but there are quite a few here who successfully take impressive images. I have a couple posted in my portfolio with both cameras but they arent really that impressive. With this type of shot it seems to be all about location.
