Hi,

I want to start using my CG for studio work as well. I shoot mainly portraits, fashion, glamour and nudes. I have a couple of 300Ws Strobes. Since I used my digital SLR, this was plenty of light.
I guess with the CG I'd be shooting at f/11 most of the time.. Do I need stronger lights?
I'm a techno nitwit..

You've got enough to get started and find out whether f:11 gives you enough DOF for the kinds of effects you want. If you've got room, you can always move the lights closer to the model for more light.

In the long run, more power will give you more flexibility to use softboxes, umbrellas, bounce cards, diffusers, gels, additional accent lights, smaller f-stops, etc., but best to use what you have and discover what you really need in practice before spending money on lights.

I don't speak WS. WS is a measure of power entering the flash head, not of light emerging from it. What is your flashes' ISO 100 Guide Number?

ah yeah.. the GN is 180ft(55m) at 100ISO if I'm not mistaken.

ah, and I think I can then calculate my own f/stop from it.. GN/distance=F, right?

Exactly. Lotsa power. Two of 'em have a combined GN of 255.

One evil thought. My beloved Vivitar 283s have rated full power GN = 120, but my flash meter and film both find GN = 80 for the weakling and 90 for the strong one. So you probably should check how much light your flashes actually put out. In any case, lots.

Cheers,

<blockquote> Hi, </blockquote>with two 300WS strobes you're in business. You'll probably end up using fairly slow shutter speeds, so your models will have to hold still and you might want to keep the wind machine turned off. <br>     What's your flashmeter say about f-stop/shutter speed combinations? If you don't have a flashmeter, you should consider buying or renting one. <blockquote> <blockquote> Dan </blockquote> </blockquote>
