Strobe Lights White Balance and Surrounding lights

I just got a 2 sets of Strobe lights and the Boom Stand. Got a couple question I hope someone can help answer Q1) White Balance I set the WB to the Gray Card shots that I took manually but the photos comes out bluish. Normally I use Model lights and set the WB per the Gray Card and it turns out fine. With strobes lights I am having this bluish color problem. It sounds like when you're doing the gray card WB the camera is trying to white balance ALL the lights, not just the flash. So, forget the gray card. Just use the camera's "Flash" or "Daylight" WB preset. That should be good enough. And take your camera off "Auto". Set f-stop and shutter speed manually. Also, how are you triggering the flashes? What camera are you using? What flashes? Q2) Ceiling Lights turn off? When I use Strobes lights, do I turn off all the surrounding lights (e.g ceiling lights etc) and therefore leaving no lights except when the Strobe lights flashes? Is this way to do it? You can. Or if they are part of the composition, you can leave them on. It's entirely up to you and what type of effect you're looking for. Flash exposure is controlled with f-stops. With flash, since it's "instantaneous," shutter speeds have little affect on its exposure, but a lot on continuous light sources. So, if you set your shutter speed manually, you can control the amount of ambient light in your shots from a lot to none at all. But don't set the shutter speed higher than the flash sync speed. You can set it slower, just not faster. -- Fotoguy Contributing Expert BestInClass.com "Personalized digital camera recommendations" http://www.bestinclass.com/digital-cameras |

Don't forget you can also use ND filters/gels over the lens as well to bring shutter speed down to X-sync. |

You can set it slower, just not faster. Don't forget you can also use ND filters/gels over the lens as well to bring shutter speed down to X-sync. Or just use any of the high quality P&S cameras that rival or beat most DSLRs in image quality. They don't suffer from X-Sync limitations. The CHDK compatible cameras having full-frame flash sync up to shutter-speeds of 1/40,000 second. That's shutter-speed, not flash-duration. Flash-duration runs from 1/10,000 to 1/64,000 (up to 1/224,000 on some of them). What good is having camera that has slightly cleaner high-ISOs if your moving subjects are going to get ambient-light blurring from your crippling-slow focal-plane shutter speeds. Some of you people can't seem to think things through far enough. Betty: "Oh, what a nice picture of little Billy. Look how crisp the image is of him waving bye-bye when using flash. But what's all that odd yellowish blur around his hand? And why does his face have a weird yellow blur to it?" PRO Photographer: "Shhh... pretend that doesn't exist. That's caused by the ambient incandescent lighting and being limited to X-Sync shutter speeds when using flash with these expensive cameras. Anything moving in the scene, like his hand waving or him turning his head fast will get the slow-shutter speed effects from the ambient light. The flash-duration being fast enough leaves a crisp outline inside of all that X-Sync shutter-speed motion blur. That's why you get the crisp bluish-white flash image with the yellow blur around it. I could have used a good P&S camera with a leaf-shutter that doesn't suffer from this problem but then nobody at your kid's birthday party will think I'm a 'PRO'. Why else would I spend so much money on a camera? Just look at the results. You'll never be able to believe that I'm a 'PRO' from the quality of my photography. The only way you'll think I'm a 'PRO' is if I own and try to use a DSLR. What do you want? Good photos? Or someone that looks like a 'PRO'? You can't have both you know. Not with these kinds of lighting conditions and having to be crippled by using X-Sync shutter speeds using last-century designed focal-plane-shutter cameras. Only 'PRO' cameras suffer from this problem. This is why we are 'PROs'!! Can't you tell? No, no, don't look at the photos to see if I'm a 'PRO' or not, LOOK AT THE CAMERA! .... See? I'm a 'PRO'!" (They're so funny!) |

Ironically, if you use a Canon P&S, and load chdk onto it, you can have Flash-Sync speeds of 1/10,000 of second, sometimes more. This is the only technical advantage of a P&S digital camera. Some of the newer D-SLRs also have an electronic shutter and are not limited by the mechanical focal plane shutter and can go up to 1/500 sec, the same as a good P&S without chdk. |

It's the "only technical advantage" in the mind of someone who has never used any camera. There are hundreds of technical advantages to high quality P&S cameras, but since you've never used either, P&S nor DSLR, you'd never know this. Some of the newer D-SLRs also have an electronic shutter and are not limited by the mechanical focal plane shutter and can go up to 1/500 sec, the same as a good P&S without chdk. How odd. Even a P&S camera that I bought 8 years ago allows full-frame flash-sync up to 1/2000 second. I guess that just proves that you don't know what the hell you are talking about, again. Enjoy your ignorance. It becomes you. It is you. How's your other virtual-life pretend careers going? How about that computer controlled geyser that you installed in Yellowstone Park? Been back to reprogram that lately? LOL Anyone that's curious, do a search for SMS and computer controlled geyser. This TROLL is so out of touch with reality it's not only funny, its hysterical. He knows as much about cameras and photography as he does about anything else--only what he invents in his pea-brain. |

Yep, logic strikes again. Now, about the flash power at your fabulous speeds, is that even one milliwattsecond? Will it visibly light up a bright white paper 10 cm from the lens? What good is having camera that has slightly cleaner high-ISOs if your moving subjects are going to get ambient-light blurring from your crippling-slow focal-plane shutter speeds. Yes, if you glue the shutter open, you might have problems. Fortunately, normal people don't act like you. Some of you people can't seem to think things through far enough. What was the reason for using studio flash units, again? To look cool or to have them stand in the way when you use that P&S of yours? [Snipped a lot of crap coming from a swine's mind. Let's adjust that for reality:] Betty: "Gee, little Billy boy looks so *zombie* with his gleaming paperwhite skin and his red red eyes! And his face looks so flat, too. And such great strong film grain, even in colour, just as if a demon had mixed up the image! The teacher always says he's possessed by the devil, but how did you manage to get him look so terrible on paper? All the other photographers can only show a little pretty angel, and never go all the way to show shots looking like real oil paintings by mad apes! And how he looks so ghost-translucent in parts! What's your secret?" Photographer: "Wellll, I bought a crappy P&S camera instead of my proper camera bodies and lenses, because some usenet troll without a real name said they were oh so much better. I spend many thousands on real gear, but that P&S won't even interface with my studio flashes. So I use it's inbuild flash for ultra short flashes, but have to expose very long to get at least some light onto the sensor. Now, the flash makes the eyes red and the skin zombie-ugly, and the long exposure makes your boy look translucent when he moves. Because of the little light I can use --- remember, my expensive studio flashes won't work --- I must use high ISO and brighten the image a lot --- that causes the demon ape colours all over, and the noise control software makes it all look detailless like an oil painting. Luckily that camera has a tripod hole, or it would look completely unsharp as well." Betty: "Marry me! I want your baby! Now!" [We close the curtains over the little scene where the Betty's eyes start glowing red, she turns half translucent and the photographer gets possessed as well.] (They're so funny!) You're so out of your depth, it's funny. -Wolfgang |
