Last night I did a dry run of setting up my "portable" studio kit and took a few test shots. One reason I setup the kit was to get an idea of what I might be missing and a few ideas about properly setting up the lighting.



Lacking any other models, I used the two objects above. How's my lighting? Decent? Needs work?

The backdrop is a roll of slightly off white backdrop seamless paper.

This is what I learned that I need to acquire...

Clamps. I need clamps to hold the roll of paper together so it doesn't continue to unravel.

Weights.I also need at least two, possibly three clean sand or plastic covered weights to hold the paper in place on the floor.

More Lights. I currently have just one Alien Bees kit and I used two of those inexpensive clamping lights that you can stuff 100-watt bulbs into. I used one of these clamped onto the legs of one of the backdrop stands, to give a little light behind the subject to take care of shadows from the strobe and my helper held one from above, ponting behind Elmo.

More Space. I setup everything up in my basement. Unfortunately, the area that was available is cramped and thus I was right on top of the subject, the lighting was right on top of the subject and everything was just to blasted cramped.

Looks underexposed and slightly blue.

Your light looks like it's coming from the right. Do you have a reflector on the other side? If the subjects are far enough from the background you shouldnt have to worry too much about shadows.

You should try not to mix different kinds of lights as this would definitely give a color cast. Use a reflector, or make one using a board and aluminium foil.

So, don't even bother with other light sources, just the single strobe and a reflector?

I'll have to see if I can work that out this week.

Exactly. Depending on your strobe and how much power you have, in a small space all you need is reflectors and one strobe. People do portraits with reflectors and a single strobe in large studios too. You just need to practice with it.

Ok, this might sounds stupid, but what it s STROBE light? When i hear strobe, i imagine, the black box with white light that blinks really fast in clubs and somehow i doubt that's it.

A strobe is another name for a flash unit. It's the opposite of a continuous light source - it flashes to emit its light source when the shutter is released.

You will get a color cast, unless you correct one source to be the same color temp as the other. Usually, that's done by placing a gel over the strobe to balance it with tungsten.

A reflector will make a good fill, You don't even have to bother with the foil, just use a big white card.

Yup. Your Alien Bees is a strobe. Your usual bulbs, work lights, lamps etc are "hot lights", that is they give off light continuously and get hot. Strobes just let out a lotta light in a very small amount of time. A white card will work very well as a reflector too. Depends on the situation.

I do have a collapsable reflector that I can use and I could also setup my hammerhead flash to act as a slave or switch around the strobe to kick out a low-power flash from behind my subject.

Here's one of the pictures from the photo shoot I was talking about.



Details of the shot are in the description. (I really do think I may need another light.)

Here is a closer crop of the previously uploaded image.

sorry for more newbie questions but define "big white card"... do you mean like posterboard???
01/15/2007 09:45:48 AM · #15
Yes.

Bright white, this would "bounce" back the light that hits it.

Are you using a light meter? Part of the underexposure could be because you're using f/22.

PhotoFlex has some lighting lessons that could help, including a fair number of one light/reflector combinations.

You're always going to need some PS work. The above took only a few minutes, but clearly it would be easier and quicker if you got the lighting sorted out too.

My backdrop isn't pure white.

It's slightly off-white.

Yes, or whatever you have that will work

I don't have a light meter. I was going from what I could see as the results on the LCD. I could overexpose the shots by a stop or two in the conversion software and see what that nets me.

I also did do some photoshop work. (Cloned out a mess of stray hairs, some dried milk nobody noticed on her chin and a few blasted dust particles...)

Your in camera light meter will likely want to under expose with a giant white background (remember it wants to turn the whole thing 18% grey) so remember to compensate for that.

Also keep in mind that when using strobes your shutter speed controls the ambient light and your aperture controls the exposure. So if you are under exposing the image then open it up a bit more.

Edit: Just wanted to add that 18% grey is about 2.5 stops darker than white. So theoretically you could meter off the backdrop (assuming it's what you want as pure white) and then bump the exposure 2.5 stops from there.

There's one source of your troubles.
