I just got my hands on a pentax k10d and wanted to get into IR shooting. Does anyone have any experiance with this type of photography enough to recomend a good IR filter????

 

I just got into it in October with a Hoya R72. I've been waiting for it to get a little greener outside for me to do some more work with it.

It's not easy because the filter is nearly opaque to visible light, so you have to compose the scene without the filter, then screw the filter on before you shoot. Metering is hit-and-miss too, and your exposures will be very long.

I don't know much about how well the K10D responds to IR, so you'll have to do some research there. The other thing is not all lenses are "IR friendly. Every lens has coatings and dampers to prevent light from bouncing around inside, but those coatings are usually just optimized for visible light. If the lens isn't IR friendly, then you'll end up with a large hot spot in the center of the frame. I know of websites that list IR friendly lenses for Nikon and Canon, but I don't know of any for Pentax, so you'll have to do some digging there too...

 

yup, I did it once. Just as Dan said if not perfectly set up, your results are duds. My 30D will be sent to be IR modified with in the next month or so.

 

Cool! Are you going with Lifepixel, and if so, what conversion will you be doing? I like the false colour, but most of the time I prefer the high contrast B&W look. I'd have a hard time choosing...

 

Yes, with LifePixel. I too I'm having a hard time with which one to do. I'm leaning to Contrast B&W because I like b&w so much. But with the Standard you can pp to contrast b&w.

 

The high contrast b&w filter cuts through haze better because it more aggressively filters visible light, so clouds and distant objects are much sharper. I don't know if you can completely achieve the same look with the standard filter and processing, but then again, you can't get any colour from the other filter, so it's a trade-off. It would be really nice if the conversion let you swap filters as needed...

 

That's true pp is not going to give you what was there, only adjust what you have.

 

Speaking of IR, this lens looks pretty cool: http://www.imaging-resource.com/NEWS...urAASQpRU.html

 

With an old pentax I'm sure there a lot of great older lens that have little no coating that you can pick up for cheap.

 

Thanks for the tips everyone. I'm looking into getting a new wide angle and a macro new, But maybe I can find an old lens on ebay or something for IR.
