Just bought a infra red filter (77mm) from the bay for my 17-55mm F2.8. I got a non brand one as the Hoya one was like £90 and this was a third that. Has anyone used IR filters much? I really just fancied having a play with one to see what you can get out of them.
 
When you know just how to approch infrared you can produce some of the most amazing artwork.
Its kinda one of my things. I am a passionate artist and infrared is one of my productions. I started out using the Hoya R72 and progressed to DIY my own camera for IR only. which is why I can photograph portraits in infrared.

Depending on your model dslr you could be expecting your exposure times to be beyond the 10 second mark (1min+)

what camera are you using, some are better than others for IR photography.

before you take any shots with it, setup a custom white balance, using green grass as a reference instead of medium grey.

apart from a few minor level tweaks, that is all i do with my IR stuff.

I've got a 400D. Thanks for the tip on the custom white balance, will do that once I get a go with it. That second shot is immense!

absolutely true.
The best infrared shooting conditions are dependant on camera/strengh low pass filters, the suns overal light and heat of that day to determine the best condition for infrared.

Got an IR filter last year but never got round to using it.
Will give it a go this year as long as we get some decent sunshine.

Any one got a link that lists all the dSLR's and how good they are at IR.
I know the D80 aint brilliant at it but wondered what older Nikon bodies are more receptive to IR without modification.

D50 and D70 are really good cameras for IR work. D40 is pointless to be honest. :)
 
I really enjoy IR work. I've done a fair bit of experimentation with a Nifty and Hoya R72 on my old 350D but 50mm is rather restrictive.

Unforuntately a 77' filter for my 17-40L/10-20EX is prohibitively expensive right now, but as soon as I finally hit the buy button on a Cokin filter mount set I'll most definitely be taking some time relearning the art on my 50D.

regards setting the WB, with IR filter attached or without?
I know a "noobish" question but having managed to get my IR filter fitted to the Cokin P mount and looking pretty "light tight" might as well give this a go.
Office is out in the sticks so plenty of green stuff to shoot.

Suppose what im after is "Dummies guide to shooting IR"
 
Firstly. You want it screw tight. I would only invest in a threaded filter holder.
All sensors are sensitive to light. Its the strength of the low pass filter infront of the sensor (the thing you all touch with your sensor cleaning pads)
The D80 onwards are fitted with more more effective low pass filters whereas the D70/50 aren't. Canon have always pretty much been fitted with a decent low pass filter giving the early nikons the advantage.
I think the Canon 10D had a weakish low pass filter but anything onwards from that is pretty defensive meaning that Canons generally take over 10 seconds to expose where as the nikon D70 can pretty much do a F16 shot at ISO 200 within a few seconds. That kinda setup on a Canon would probably be over 1 miniute or several minuites.

set white balance with filter on.

with regards to how sensitive the likes of the d50 are, that second shot of mine was f22, iso 200 and took 13 seconds to expose - thats shot on a d50.
 
you'd think so.. but it doesnt seem to really work.

i use a different work flow for IR, normally i use lightroom and then cs3, but with IR, i use Bibble instead as it can read the NEF files properly and preserves the cameras white balance setting properly
 
will see how i get on with the drop in filter.
If its any good will look to a screw fit filter, if not may be time to go on flea-bay for a cheap D1/D40
 
Filter came just now. Had one quick try with it on my 400D:

I set the white balance on Lightroom as I couldn't work out how to do it on the camera without getting the instruction book out which I didn't have time for. I had to do a really long exposure (30 sec) so get it visible enough. Not sure if that's due to the camera, lens, filter, subject or what. When I get the chance I'll have another go somewhere other than my balcony.
