i would like to ask guys here , i satrted photography about 6 months ago and pretty much ok with my camera shooting with regular ambient lighting and flash. i have a nikon D70 and sb600 . I am wondering if i wannna explore more of multiple lights off camera - probabl using manual mode . how do you guys measure how much lighting you need . i know there are formulas doing the math about distance , aperture and guide number - can these numbers also be had with the help of a light meter?
Are you thinking about adding more Nikon speedlights or getting into studio lighting? If the latter, I always suggest starting with one light and a reflector. What do you want to shoot with the multiple lights? Give us some more info and we will be able to advise.
im thinking more on studio lighting . - from headshots to whole body portraits, still also probably. so it would be better to start simple with 1 light and 1 reflector .
Then I recommend: 1 Alien Bee 800 strobe 2 heavy duty 13' light stands 1 large foldable softbox 1 5-in-1 round reflector with bracket for light stand 1 pair background supports with telescoping crossbar 1 muslin background of your choice (not white unless you want to get more lights) This is a system that you can build on as your expertise and confidence grows.
Nothing is "required", but a meter is very helpful, especially when working with flash. It's a great timesaver. I keep a flash/ambient meter handy and use it for both.
Not a must - you can always check your LCD and histogram and adjust flash power etc. until you nail it. However, a meter makes it a whole lot quicker and easier. It also makes it a snap if you want to get a specific ratio between your lights. So . . . I would recommend one.
