... How many watt seconds do I need? I'm using a 35mm film camera. I'll be shooting in my single car basement/garage and a smallish living room. Ambient light from sun is dim, EV4 at 100 ISO for both. I'd like 3 lights, main, fill and hair/bg/kicker. I assume the main and fill should be the same w/s but how many w/s should the other light be? I'm trying to come up with a ratio like 1/2 or 1/4 as many w/s as main. I also want more than 3 power levels. I think this would be more versatile and may be a necessity since I don't have room to move lights further from the subject to reduce power. What do you think? I apologize if this question is vague but I have never purchased studio lights before. Thank you for your help. me Remember the old quote, "Speed costs money, how fast do you want to go?" Substitute "Light" for "Speed' and "bright" for "fast." The lights I have only give me about 700w/s, but they've been sufficient for my purposes in the small space I have to work. -- Skip Middleton http://www.shadowcatcherimagery.com |

Two different lights with the same ws rating could put out vastly different amounts of light He wasn't asking about how much light, just a guideline on what he would need. As most monolights, and a good number of packlights allow you to control the power downwards, he just needs a reasonable top end. The various answers he got based on room size should be ample guidance.

What manufacturer's specification do you use when comparing? Thank You, You can only compare W-s. On the AlienBees site, they use to put up what aperture setting you would get at a fixed distance (10 ft.) for ISO 100 when using their basic reflector. (I don't recall if they gave a GN equivalence for this too). They've redone their website since then, so not sure if the same info is still there. Why don't strobe manufacturers give GN? Mainly becasue of reflectors and the behaviour of packed strobes with various cable lengths. For what you want to do a couple 400's and a 200 would be ample, a cut above (2 x 800 + 1 x 400) would give you more manouevering room. But as I said an AC strobe or two is handy for touching up the lighting here and there.

Two lights on the pack can be adjusted but starts at 600 a piece, two stops down from full power is 150 ws per lamp I believe. I only need that much power on occasion for groups. -- LF Website @ http://members.verizon.net/~gregoryblank "To announce that there must be no criticism of the President, or that we are to stand by the President, right or wrong, is not only unpatriotic and servile, but is morally treasonable to the American public."--Theodore Roosevelt, May 7, 1918 |
