Years ago when i had a film SLR i tried infrared film with some nice results.

Now I have a DSLR I am wondering what is the best result for obtaining infrared images, would it be to use a infrared filter over the lens or is there some sort of plugin for photoshop cs4 etc?

What are other peoples experiences of using the filter or the photoshop way of infrared photography?
 
Some dslr's are more sensative to ir than others, some will give not to bad results with an ir filterover the lens but with very long exposure times and loss of af and metering iirc, so a tripod would be needed, I know that there are companies that replace the filter on the sensor, advanced camera services charge about £300 , may be worth picking up a cheap second hand body and getting converted as they will still af and meter as you keep "normal" shutter speeds so you do not need a tripod to shoot.

As for PS I do not know anything about them.

Neither, PS is "cheating" and the filter-on-the-lens type leads to 15-20 second exposure times. A converted camera is the best way to go, but it can be a pricey option if it's only going to be used as a toy.

There was, however, a guy in Ireland converting Fuji bridge cameras a while back, a brand new one was around £200, not sure if he still does them though.
 
quick test if you want to see if your camera will pass through IR - set camera on a 2 second exposure manually, go into a darkened room and point a telly remote at the lens. Press the shutter release and press a couple of buttons on the remote. If you get a coloured spot on the resulting image, it'll pass enough info to work with one of the cheap fleabay IR filters - albeit with maybe a 10-20 second shutter speed.

This was a first attempt, out of back window, on reciept of the filter - EOS450D...



or with the read and blue channels swapped in CS4



or a full BnW conversion, for the purists :lol:



I know the photo's poor - but that's the view from my back window - what can I say? At least it illustrates the possibilities :shrug:
 
TBY i tried your experiment and i got a clear light source on my Nikon D3000. I think I will get one of those filters, although I am guessing that they are best used in the spring/summer when plenty of foilage is about?

thanks for the replies
