Hi all.
I was curious about what was being achieved with IR and thought I'd check out the POTN gallery.

:shock:

There wasn't one, but now there is!

Post'em if you've got 'em.

what does it take to do an ir pic, do you HAVE to modify your camera or is there filters or lenses that can do it? sorry for the newb questions

It's the place for them, and I hope somebody can answer!
I started the thread because I wanted to learn more too, so I'm no expert, but as I understand it, a modification needs to be made (Just on some bodies? Am I confusing this with mods for astro work?) to the filter on top of the sensor to allow IR light to pass, and a filter that basically looks black is put on the lens to keep everything except IR out. Some lenses work better than others (some have "hot spots"; maybe the coatings on some are problematical). Exposure times are very long.

I just wrote a paper on infrared photography for my History of Photography class a few weeks ago...although I have not done the method yet :cry:
there are filters that produce the effect. The filter blocks wavelengths that are NOT infrared, allowing infrared "light" through to the lens.
but you can also have a camera modified. The only problem with this is that you cannot reverse the procedure...you must be willing to have a dedicated camera for infrared photography.

from what i read, if i buy this

http://www.bhphotovide​o.com …67mm_092_Infrar​ed_IR.html (external link)

then i can just pop it on a lens and take ir pics? it says this in its discription

"The B&W 67mm 092 Infrared (IR) Filter is an IR TRANSMISSION filter and blocks most of the visible spectrum (below 650nm). It transmits the upper end of the red spectrum (90% transmission at 730nm) and beyond (i.e. IR radiation). Basically this means that this filter will allow the sensor to see deep reds and IR but no violet, blues or greens will register - it will give you the kind of results you would expect to see from IR photography. The 092 has a deep red cast that you can only really see when you hold it in front of a light bulb. If you are wondering which filter to purchase to shoot digital IR images try this:First, make sure your camera is IR compatible. A simple test for this is to aim a TV remote into your lens and take a photograph of it - if you see the red dot, then you stand a more than good chance of getting IR images out of your camera. Digital sensors or chips are IR sensitive by nature and so camera manufacturers install an IR blocking filter in front of the sensor to absorb excess IR. However, some of these filters perform better than others and that's why a simple test will determine your camera's capabilities.
The B+W filter ring is made from brass yielding a stronger product. Brass filter rings are also less prone to jamming. In addition, the seal between the glass and filter ring is exceptionally strong giving the filter added strength and durability. The excellent Schott Glass used in the manufacturing of this filter is legendary and synonymous with the highest standards of filter production. It comes with a solid 10-year warranty. The MRC coating on this filter adds to its durability - particularly under less than optimal weather conditions. In addition, the hard coating makes cleaning the filter easier - especially when it comes to removing fingerprints or surface dirt. Moreover, this filter benefits users of digital cameras whose shorter focal length lenses are more susceptible to dirt and other contaminants on the front lens element.
IMPORTANT: The B+W 093 filter blocks the entire visible spectrum yielding much more dramatic results and looks completely opaque to the naked eye. Its transmission only begins to exceed 1% at 800nm rising to 88% at 900nm."

but if it looks opaque to us will AF and light metering work? or do you have to go manual and trial and error for settings?

Infrared light is not measured the same way as "visible light" is, so an in-camera or light meter is pretty useless.. So you will have to use the trial/error technique.
But yes, that is the correct kind of filter to use for this.

sweet thanks, is there a temp range (i think its what it is?) i should go for or stay away from?

mind you, I have only read about infrared photography, I've never actually done it...but from what I've read, I'd try to stay above 700nm (nanometers).
Here, we are talking about portions of the electromagnetic spectrum, which includes gamma, X, radio, microwave, visible, infrared and ultraviolet waves....all which are measured by "wavelength."
