Re: How much light is needed?

Hey Guys,

I have been doing some experiments with two studio flashes (360w) to illuminate face captures. However, I have been only able to capture at 1/8 shutter speed, with an ISO of 200 and an aperture of 13 (to minimize DOF). My question is, how are some capturing at 1/10,000?! Even with 1/1000 I have a close to black image, how much light is actually being fired into to the scene for illumination? Any insight would be greatly appreciated.  ;D

Thanks,
Corey

What settings did you do for 360 watts flashes?  Iso100, aperture13, 0,5sec. shutter speed ?

Hey Exhale,

Originally I was using Iso 200, Aperture 13 and a shutter of 1/8th, but now I have added two additional flashes (total of 4) and have been testing with Iso 100, Aperture 16 and shutter 1/5th. I haven't been doing anything with motion, just trying to get consistently sharp photos. :)

Thanks!

EMULAT3D Thanks for your reply,

So now you have 4 x 360watts flashes. I believe good upgrade :)
Any other light source ? Led , projectors or etc. ?
By the way, how many cameras do you have?

Thanks

Right now we have 20 Canon T3's, arranged in a semi-circle (haven't found a good layout for 360 captures with such few cameras). As for other light sources we have a few 60w umbrellas around the capture area providing some additional ambient light. No projectors or LED's...yet.  ;D

The semi-circle is good. Will you upgrade the number of T3s later on?
Did you have any problem to connect cameras to pc? How do you connect, single pc?
I have some problems with my long USB cables :=)
