Subject: Infrared Question !!

Hi Guys N Gals. How can i tell if my camera can take photos using an infrared filter. Theres nothing in the manual and i didnt want to buy an infrared filter if it can't work. I have the Canon 300d SLR model.

You'll always have problems as a digital camera (I have an EOS350) has built-in safety against IR and, to get true IR, you'll have to remove this. This is not for us amateurs, and cannot be undone on Canon. You can get fake IR but the you'd have to compose your pic without filter, and then screw it on, you'd have to adapt focusing and take into account that lighting is critical. If you own photoshop, a quick way to get IR-like effects is to swap red and blue channels and then play with levels/curves.

Hey Lou. Glad to hear someone else is interested in digital IR photography around here. Looks like you at around a -10/-11 EV lightloss. Substantial, but not too bad. My Olympus C8080 is at -13.5EV, but I still get decent results with a Hoya R72 filter. Take a look at the thread that was recently in the forum. It should help answer most of your questions. There is a link there to a camera comparision. Unfortunately, most newer digicams are less senstive to IR as Gongyla points out, but it can be worked around. I've still got that Canon 20Da on my wishlist though. ;]

HI this question was answered earlier in a diff thread. The 300d will work with either the HOYA R72 IR Filter or the Cokin "P" series filter, the exposure times will be long and you will have to fiddle a little, but remember to remove ANY UV/POLARISERS/SKYLIGHTS filters before using it, you will also need a remote, tripod and patience.....

I just thought I would let you know that there is an Olympus C2020z camera up for sale on eBay right now. You don't see them to often, and they are famous for 1) being able to capture handheld IR photographs and 2) having a pleasing color balance right out of the camera. If you want to get a camera for IR, you might want to check it out. Just go to eBay and type in this search: "Used Olympus C 2020 Digital camera 4 infrared pics" You can see some sample photos and find more info here: http://www.jr-worldwi.de/photo/index.html?olympus_2020_ir_sensitivity.html http://dpfwiw.com/ir.htm#sensitive http://www.pbase.com/qwaspolk/qwaspolk

i read somewhere that the quick and easy test is to take a shot, in a darkened room of the front of a TV remote... then do the same with you pressing one on of the buttons... compare the images and if you see a bright light coming from the IR LED then your camera is IR sensitive :)
I'm yet to discover if my 30d does this...

ooo - i just did a test - admittedly on a bulb exposure of around a second and it showed the LED... 😄 now if only i could justify the expense of an IR filter... hehe

The Hoya R72 is not very expensive, and just about the fastest of the IR filters assuming you use 55mm filters, 16.22 on Amazon. How could you not justify that?!? :)

I'm a big fan of IR....thinkin of getting my G6 converted over to FULL TIME IR at some point...but for now the Hoya R72 Filter works fine....a bit more of  time needs to be invested because of the slower exposures needed...but thats ok by me...I kinda like the movement captured at times






TwoPynts ( ) posted Fri, 16 March 2007 at 3:41 PM

Nice Joe! I like the sense of movement too, but not all the time. To be able to take sharp, handheld shots will be quite a treat. I have a converted cam on the way...

I read where you can change the digial camera for $350 just do a google on it.  I took a lot of images useing neon paint and other stuff that will glow in UV lighting. I know it the other end ot the light range but I did get some infrared black and white film for a 35 mm camera. cost $18 for 36 shots. I scan the film and it came out diff that the prints that came from the camera shop. some of the images is in my gallery. But with the neon paint and UV lighting I got a lot of super photos over 2000 that is very good. I did not post them all. they all thought out my gallery. for color slides on 35 mm [that all you get on color will cost you $32 a roll of 36. need to have filters for your lens too. Look thatup on a google too. Oh you can buy infrared digital cameras too i saw them too ;do a google on that too Here is one of my UV lighting photo.

what you see is not what you know; it in your face

I think I will start a thread dedicated to IR photography (and UV) since there is an interest, and will link it back to this one. Jocko, depending on the cameras, conversions can cost as little as $200 (assuming you have the camera to convert). http://www.lifepixel.com/shop/cart.php?m=product_list&c=2 And there are plenty of tutorials out there on how to convert your own camera, if you are daring enough. http://www.lifepixel.com/IR.htm http://www.jr-worldwi.de/photo/index.html?mod_oly.html Thanks for joining in!
