whatever 0 #1 February 18, 2004 anyone have any knowledge and/or experience regarding using a bullet cam with lowlight and IR sensitivity in low-light to complete dark situations? I have a Sony 21CWSHRX (with EXVIEW and HAD for the acronym junkies) and was wondering about the best way to illuminate the subject matter in IR for this purpose? Would a LED flashlight be the ideal thing if I just replaced the white LEDs with IR LEDs? Also, I'm using a PC105 camcorder (and will be with the bulletcam) - any hints on how to get max picture quality from the bulletcam with this setup? While I'm here: does the nightshot mode on my 105 do anything other that illuminate with IR light? thanks sam soon to be gone Quote Share this post Link to post Share on other sites
LouDiamond 1 #2 February 18, 2004 Shoot me a PM as to exactly what you are trying to accomplish.

quade 4 #3 February 18, 2004 Sony makes some IR illuminators that run off of AA batteries that might be appropriate for night skydiving purposes. What exactly are you trying to do?quade - The World's Most Boring Skydiver Quote Share this post Link to post Share on other sites
DBCOOPER 5 #4 February 19, 2004 I have a little key ring style IR flash light (micro photon)that I used when flying with night vision goggles.If you want it let me know.Another thing that will light up stuff with IR is just about any remote control.Its a strobe effect but it will illuminate the subject.On my trv22 I can only input to the camera with a bullet cam in the vcr mode and none of the fancy features (night shot)will work using an aux camera.Replying to: Re: Stall On Jump Run Emergency Procedure? by billvon If the plane is unrecoverable then exiting is a very very good idea.

Paul, A half dozen IR Leds on a PC board would do the trick. A lot cheaper and smaller too.--------------------------------------------- Randy Quote Share this post Link to post Share on other sites
quade 4 #6 March 11, 2004 I dunno Randy. There's something to be said for buying off the shelf sometimes. Sure you could probably whip up a simple IR illuminator in an afternoon, but you still would have to build a case with a window and secure the whole shebang. Sometimes it's just not worth the time and effort if there is an off the shelf that already exists.quade - The World's Most Boring Skydiver Quote Share this post Link to post Share on other sites
cpoxon 0 #7 March 11, 2004 QuoteWould a LED flashlight be the ideal thing if I just replaced the white LEDs with IR LEDs? A while ago I bought a sheet of film which only allows IR wavelength through, the idea being that it would be placed over the lens of a regular torch to generate infra-red illumination and the torch could be attached near the camera. I used it with a smallish Maglite but the results were disappointing. I don't know if it was because the beam was too weak/narrow or just didn't produce the correct wavelength to be filtered. I wanted to test it with a much larger torch, on a BASE jump where a torch would have been conspicuous but shortly after I lost the filter sheet (which wasn't cheap) and I haven't been able to find another source since. I'd still like to try it.Skydiving Fatalities - Cease not to learn 'til thou cease to live Quote Share this post Link to post Share on other sites
LouDiamond 1 #8 March 11, 2004 That technique is what I recommended to him in PM but the big difference is the light source and the IR filter. I have used that combo using a SureFire light with the IR filter on it. The quality(intensity) of the light put out by the surefire can be seen several miles away easily. With a quality IR filter on it the night shot on the camera will pick up very good detail when the beam on the sure fire is set fairly wide. The surefire and IR filter are a bit pricey but the quality is unquestionable. IR LEDs will not put out enough light for the intended purpose in this application. It is also one of the reason why we don't use them as illuminators for our weapon systems use with NVGs. The intensity just isn't there."It's just skydiving..additional drama is not required" Some people dream about flying, I live my dream SKYMONKEY PUBLISHING Quote Share this post Link to post Share on other sites
MagicLou 0 #9 March 29, 2004 Which Surefire are you using, and What IR filter?Lou ___________________________________ . . . now you see that evil will always triumph because good is dumb - Dark Helmet Quote Share this post Link to post Share on other sites
