allrightscud 0 #1 February 7, 2005 I know this is of non skydiving content but I reckoned someone might be able to help.Anyone got any suggestions about how to get better footage from filming under sodium floodlighting. The orange colour has wasted my mini movie, which I was doing for my brothers 21st at an indoor go karting track. Would a filter work? Too much is never enough! All right scud?

bmcd308 0 #2 February 7, 2005 Sodium lights are tough. This is from Ken Rockwell's article on WB: >>Orange street lights are always going to look orange because they are orange. White Balance can make what looks white to us look white in photos, but it won't make orange white. More technically it's because these lights use sodium gas instead of dog poop and the sodium molecules create just one exact color (wavelength) of light at 589 nm which is that orange color. These low pressure sodium lights are deep golden orange and everything in them likewise looks a shade of that same color. They have no red, green or blue light to balance. High pressure sodium lights are the ones that look more whitish orange and things seen in them may have a teeny bit of color to them, but they still won't white balance.<< Brent ---------------------------------- www.jumpelvis.com Quote Share this post Link to post Share on other sites
dragon2 2 #3 February 7, 2005 I was trying to take pics in a swimming pool this weekend and was having trouble with the lighting, when I put the white balance to "auto" (having tried every other setting for WB) it worked If your camera has different settings for the white balance try that first. Otherwise, I think you need a blue filter but not sure if you need a blue 80A or 80B or 80C (they are for different color temps). ciel bleu, Saskia Quote Share this post Link to post Share on other sites
quade 4 #4 February 7, 2005 Most cameras (all Sony at least) have a feature called "white balance". This is to compensate for the spectral qualities of light sources. Most people set this to "auto" and things work out just fine. For better images under "normal circumstances" use the other standard settings of "indoors" or "outdoors". In difficult situations, you can (usually) manually set the white point yourself by aiming the camera at an object that is supposed to be considered white and sampling that for the camera to use as a reference. Unfortunately none of this is going to work for sodium vapor lighting. Sodium vapor lighting has a very narrow spectral spread made up of almost a single wavelength. It's horrible light (cheap, but horrible). Blame the facility for being too cheap to put in proper lighting and turn the entire project into black and white.quade - The World's Most Boring Skydiver Quote Share this post Link to post Share on other sites
allrightscud 0 #5 February 8, 2005 Hey, never thought about black and white! That might just work.Cheers for the advice all, I've never messed with the technical photo settings on my cammera manual focus is about it. I'm going to have to sit down and read the manual now!
