Incadesent lights are basically "black body radiation" sources and have a very high output in visible and IR light - out to around 15,000nm, which is where IR light turns into Heat more so than light, which is where the termo-cameras take over (8-14 micron wavelength)Unknownhttps://www.blogger.com/profile/12795391965373334153noreply@blogger.comtag:blogger.com,1999:blog-7573479494985497170.post-86568557849556697202008-07-26T06:17:00.000-06:002008-07-26T06:17:00.000-06:00Just from fireworks experience it's helpful to rem...Just from fireworks experience it's helpful to remember that shutter speed controls how long the trails extend after a burst and aperture fine-tunes the exposure, especially if you want some other subject to add interest (think audience/family and flash). Fireworks are like sunsets--a nice background. <BR/>Opening the shutter after the mortar fires but before the shell bursts makes it easier and has no detrimental effect on exposure, so you can add an extra second of shutter with no penalty. <BR/>Since you're already manually focusing at infinity (good call! Airshows also benefit) DOF isn't much of an issue so a wider aperture (F4?) and a shorter shutter like 1.6 to three seconds will give good results. <BR/>Personally, I would think it best to drop the iso to 200 or less to go with the wider aperture and use the tungsten WB preset, but these are concepts from full color fireworks shooting so I may be wrong for IR. <BR/>We'll see on January 1st? <BR/><BR/>I love how you chose to be different from the other shooters by going IR, and then sharing results with us. <BR/>It's always a delight to go above and beyond pointing and shooting and being disappointed.Keith Alan Khttps://www.blogger.com/profile/02240947048783657561noreply@blogger.comtag:blogger.com,1999:blog-7573479494985497170.post-90338474480489304322008-07-25T07:23:00.000-06:002008-07-25T07:23:00.000-06:00Another IR at night "look" that I've been playing ...Another IR at night "look" that I've been playing with is IR flash photography. I've got a Vivitar 285HV that's been modified to only emit IR (and a very slight red glow if you're looking straight at it when it fires).<BR/><BR/>I set it up for taking photos of bands in dark clubs without annoying all the patrons.

I want to present them close to out-of-camera for the reader.<BR/><BR/>IR images always need post processing and improvements.<BR/><BR/>Again, thanks for your plug-in link and any help that you give the IR photographer to improve their images.<BR/><BR/>Best regards,<BR/><BR/>-=- Jerry -=-Infrared Photography Buzzhttps://www.blogger.com/profile/14356269333611586694noreply@blogger.comtag:blogger.com,1999:blog-7573479494985497170.post-86466891337253952672008-07-20T16:57:00.000-06:002008-07-20T16:57:00.000-06:00There's some very interesting looks there!I'm curi...There's some very interesting looks there!<BR/><BR/>I'm curious... in some of the shots where the fireworks clip, would some form of highlight recovery help? Ideally you would do it on a RAW image, though I have a white balance + highlight recovery plugin for Photoshop that might be useful:<BR/><A HREF="http://www.free-photoshop-plugins.com/download-filters/white-balance-plug-in.htm" REL="nofollow">http://www.free-photoshop-plugins.com/download-filters/white-balance-plug-in.htm</A><BR/><BR/>I'd be curious to see if it might help a little.GlennChttps://www.blogger.com/profile/15111012468311796306noreply@blogger.com
