I want to place this cheap IR filter over the flash of the p&s. Take a photo with forced flash, have no visible light from the built-in reach the subject but enough IR light reach the SB26 to trigger it. Hopefully leading to a pleasing photo :) Sorry, just to explain a little more. I want to place this cheap IR filter over the flash of the p&s.

Unlike GV I'm not concerned about image quality as I am hoping to use it over the built-in flash of a p&s digital camera to fire a SB26 off camera (it has a built-in optical slave). Anyone know if it would work? I’ve been looking for a cheap IR filter and this looks great.

Yes, the pictures turn out like crap doing it this way but, as one said here, its meant to be fun. Everyone can buy a IR filter, but only a few do it that way and have a true experience on doing something different from the crowd. http://www.w3photos.com.br/?p=140 http://www.w3photos.com.br/?p=144 see my blog at www.w3photos.com.br I have some posts on my blog about this IR with film technique.

All operations took me half a day (for the first time) now I know how to do it it can be done in ~15 minutes. Film is not suitable for high resolution photography but does OK for snapshot phoography and (!!) IR video.

This afternoon I've just got developed film for IR filter. But maybe i misunderstood, I went to camera shop, bought 1 roll of film, after that i requested them develope that film. But when got bach developed film, it looked like clear & red color. I try to take picture with that developed film cover and picture look like red filter (my camera is Canon 350D). I think I had mistake, before develope film, maybe i need to roll out film. This is correct or not, please instruct me. Thank you and hearing from you soon Dear all

It does deteriorate and is easily damaged... and who knows what actual wavelengths are being passed. I now use glass IR filters on the camera, but I still use developed unexposed film as IR filters on strobe heads... Makes the flash less obtrusive ;) I'm a serious photographer (I don't take myself too seriously though) I've put pieces of panty hose behind 20,000 dollar lenses (film) because it gave the right "look"... so there.

I didnt' say it was a complete replacement for a decent IR filter - it's just a starting point to see if you like the results!

This idea does work, it's a given, but why would you do it? Have you ever wondered why professional lenses are thousands of dollars? There are many reasons why, one of them is that it will give you quality/sharp more detailed image. Adding film over, or even worse - taping it on the back of your lens, will only take away from the quality of your current lens, or it will slightly distort your image. "You" might not notice, but take it to a professional photographer and tell him/her what you've done. IR filters can be expensive because those expensive ones will try to match and blend with the quality of your top of the line lens. That is why, there will be less or no distortion at all, and it will not take away from everything that your "top of the line" lens has to offer - if you use a real filter that was designed for you lens. (There are different lens/filter sizes.) Adding this nonsense to your lens is like wearing the wrong glasses. You get your eyes checked once in a while, and if you need glasses, as you get older, your prescription will change, and your glasses will change optically. If you wear the wrong glasses your vision will be slightly distorted. Once you put the right ones on, you will notice the difference and will dispose the old ones. Your lens is your third eye, so wear the right glasses if you need so. I read a lot of these comments here, and I don’t think there is one serious photographer here.

I was up late lastnight and surfing the web when I stumbled on an Infrared video of the veins in some guys arm. I wanted to build my own. I found a nother place that talked about the exposed negitive idea. So I looked all over the house and found an one inch length of film. I grabed my sony digital video camera (tested it with a remote to see if it picked up IR) and taped the negative over the lens. I worked. I needed more exposted negative. I went to walgreens bought a roll of film opened the box and pulled the film out of the tube. Then asked the girl working to develop it for me. this was met with expected puzzlement, I told her what I was doing, that it was ok i only need the film. I got home taped two pieces of the film to the back of my Nikon D50 lens. And went out side to test. It worked so I tried 3 and 4 layers of film. 3 is darker and a little more crisp but 4 is really not worth it. 2 is a good number. But it works so for about $5.00 I have my own IR filter.

I found I had to double the layering of the film for my camera. I have a k10d, used an old 50mm f1.7 fully manual pentax smc-m lens, camera in bulb mode shooting at iso 800 for 8-12 seconds on a tripod depending on the lighting. I just did it at lunch, so the images in camera are pink-red depending on exposure time (i shot in raw, but will try custom white balance next time i use it - lunch time is only so long!). anyways, i had been disapointed last night with a single layer of film over the lens - it was still transmitting the normal color spectrum, but with the added layer it works well, if not for the long exposure. this works and is awesome, though i think it may have alot to do with what brand of sensor your camera uses. for the film, i got a roll of 120 velvia slide film for 50% off ($2.50), and they didn’t charge for processing since there wasn’t anything on the film!
