I am looking to buy an IR filter for my 58mm Sony F707. I see that Hoya makes two different ones, and it looks like the strengths are what varies on them.

Which one would you all recommend, and does anyone know where to buy one at a good price??

thanks, KJ

All my IR photos were taken with a Hoya R72 IR filter. I order my filters from www.2filter.com. Their prices are reasonable and so far I've always received everything w/out hassle. Usually, the price was a little lower than advertised there ... you'll find out before you submit payment.

//www.cliffshade.com/dpfwiw/ir.htm the be all end all for a great overview of IR imagery. I use a 72 hoya or a Wratten 87 filter. The 72 Hoya is actually a NIR filter and the 87 is true IR. Read the site I linked. It has great info... Neat thing about the 72 filter is that once you start processing you can switch the red and blue channel for some cool affects since there are color traces left...

Does any body use an IR filter on a Fuji S602Z? How are the results? Which filters do you use? Etc...

This thread had peaked my interest...

I was always curious about filters for digital cameras, I know some of them work but I wonder if the cameras internal sensors try to correct the filters effects, maybe only on a SLR Digital? Off to check my camera to see where the sensor is :).

I did the remote control test (point a remote at the lens & watch on the lcd as you push the buttons) and saw a bluish light, which as far as I can remember is a good sign. I can't recall ever seeing any IR shots with the 602 though.

Were these all daytime shots? Does it work at night?

Thanks, I don't think I have either.

Maybe I'm stupid, but how do you do this? The colouring in your photos is much more interesting than anything I've been able to come up with.

They were day shots in very bright sun... you won't have much IR light availabe at night...

This thread comes right on time :) I nearly bought a Hama IR filter which filters light below 900 nm wavelength. But this filter is pitch black! I guess that's what an IR filter is supposed to be, but for example how do I focus? Do I have to focus without the filter and then attach the filter afterwards?

I read that many use a "Hoya R72". I guess R72 means that this filter only lets light through above 720 nm wavelength. Is anyone able to give a comparison to a 900 nm filter? Would it be better to use a 720 nm filter? I guess it would allow shorter exposure times because it lets more light through, but is there any advantage of a 900 nm filter to a 720 nm filter?

I have these IR filters: Hoya R72, Tiffen #87m Hoya RM90
R72 cuts off at 720nm
Tiffen #87 cuts off at 800nm
RM90 cuts off at 900nm

Out of these 3 my favorite is the Tiffen #87 if I want B&W looking photos. Most of the photos I take with R72 cause a reddish tint to all the photos. Sometimes it works out, sometimes it does not. Now, the C-2100UZ is rather sensitive to IR light so I can hand hold the camera with any of those filters (depending out the amount of sun of course).

I'd love to show you comparison photos but I have to wait until spring/summer since the weather is pooh here.

Here's a question: can you get the same effect using software like PS6?
If your camera takes in the IR, then you could filter out the daylight using software, no?

Just asking...

Hi Dave, and thanks for that link. Looks like a good reason to hang on to the D30 instead of getting caught in the upgrade craze. Which lenses do you use for your IR shots? You're stuff is great BTW.

Actually, you "kind of" can.

My image in the song title challenge was taken using the hoya R72 filter
I talk to the trees
I also have a few ir images at infrared images
Also here more infrared
I play around with the brightnes and contrast and in some of them with the channels

I'm using a Heliopan RG 1000. It takes out everything below infrared. I put a minimag flashlight on the other side to see if I could see any light coming through. Held it up close to my eye, and no light but my eyeball got warm. Darn thing works! Got mine from a fellow on ebay. He was auctioning other sizes, but got one for me on a straight buy. Price was much better than what I was seeing in online stores.

Of course it's nice to take an infrared picture straight from the camera, but yes, you can easily reproduce infrared effects in Photoshop.
Here are some that I manipulated and there is a tutorial in my Digital Kitchen section.

Thanks. Have you created an action for this? I will try it out, and see how it goes.
Does anybody know of any plugins available for PS?

Fred Miranda has a great IR Action. //www.fredmiranda.com/DI/index.html might be the best action out there.

Galina I would suggest instead of an overall blur using the distort glow filter in PS7. (filter - distort - distort glow). This will ad a softening to only the highlight areas which in general is where most IR images get softened. IR images are more softened than blurred.

I will also add that there is nothing software based IMO that really reflects what a true IR filter (87, 87A or 89) can produce. They are close but just not there...

Thank you for your advice about the diffuse glow filter. The Photoshop section on //www.photocollege.co.uk has three free IR channel mixers. I downloaded them, but never used them - the results were a bit flat, although the picture on the web site was convincing. Maybe the values need tweaking + a diffuse glow + some creative work on selections...

Or maybe just forget it, get yourself a Hoya R72 filter and... I went today to Jessops to check the real thing out.

I have had very limited success with IR filters with my digital cameras. The only camera I have had success with is my old Kodak DC200, which I removed the hot mirror on and use with an 87 filter. This works great but only 1 MP. I got a 62mm Heliopan 87a filter for my E10 and was never able to have any success with it. I later bought a 77mm B&W 89b to use with my EOS-1D and again no luck at all. I have all but given up at this point. I thought I would be safe with the DSLR because I couldn’t see any hot-mirror at all. Obviously the hot-mirror is integrated into the CCD. Does anyone have any ideas? I love the IR pics I get with my DC200 but wow 1 MP just doesn’t cut it any more for me when taking landscape pictures.
