Convertible Umbrella tips for portraits

I'm looking for some tips on how to use this type of umbrella for one light setup
and add more lights after learning to do one light first.


I do know to move the umbrella off axis of the camera, my problem is i'm not sure how
high above should the umbrella be, or where should the shaft be pointing at my subject
for reflective? Or when using shoot through, again how high and where to point the umbrella?

What I have:
Camera Nikon D70
Sekonic L-358 Light Meter
SB-600 speedlight
2 ac slaves screw in type from adorama https://www.adorama.com/ltacs.html?discontinued=t
40" convertible umbrella
Light stand, hot shoe connector and ac connector with umbrella holder
Some reflectors

Really just need a starting point with how high and how to point the umbrella, the rest I should be able to figure out

Thank you, in advance,
Mike

I suppose you could start off with putting the light stand 45 degrees to the to right or left of your subject. Put the light above their head by a few feet, and angle the light down about 45 degrees. You could start there.

You can then make it as simple or complex as you want. It all depends on what you want to put into it, and the results you're looking for.

If you can, shoot tethered. It makes things soooooooo much easier. You can see where your focus point is. You can see what your lighting looks like. It's so much easier to see each image as you shoot, and tweak as you go. You'll never see anything on that tiny screen on the back of the camera. No matter how much you zoom in, the end result is, it's not worth a damn.

Put your camera in manual. Put the speed light in manual. Set the shutter to something less than 1/200, and maybe f/8 or something like that, set the speed light to 1/4 power and take the image. Too dark, increase the power on the speed light. Too bright, decrease the power. Forget the iittl and ettl stuff. Although it works(sometimes) it will confuse you. Keep it simple.

When you shoot tethered and look at each image as it comes in, you immediately see what you're getting. You then notice what's wrong, and you can then try to fix it. You tweak, take the image and see what you get. You immediately see what effect what you've tweaked has on the image. You'll progress much faster that way.

If you can, shoot tethered - Can't with d70

Had an idea, cheap clamp light for modeling light, worked pretty good!

I pretty much knew what you were telling me, just had some issues
with height and angle of the umbrella.

Getting people to pose is the hardest part, so practice is the best way to learn.

Thanks again,
MIke

Standard thing is Main light in reflected umbrella about 45 degrees wide (around towards side), and 30 to 45 degrees higher than head, from camera, as seen by the subject. This umbrella is placed close to subject, which for a reflected umbrella, fabric will be 4 or 5 feet from subject. Just far enough so the light stand is not seen in the picture, but subject probably can reach out to touch the the light stand.

NOT shoot-through. About 1/3 of the light goes through, about 2/3 is reflected, which is really huge wasted spill all over the room, and a big loss at subject. Such spill is not a big deal when the shoot=through is only like 12 or 18 inches, because the reflections from the walls are so much farther.

Two Fill light important factors are: Placed very close to lens axis, to NOT create a second set of shadows. Fill light should be metered to be about 1 stop less at subject than the main light. This ratio is one of the important factors. That sounds like the SB-600, on hot shoe, because it can be turned down. It could be an umbrella placed close to lens axis.

See http://www.scantips.com/lights/setup/

I don't think your slaves can be turned down? Slaves might make a background light? You could reduce their power maybe by covering them with a couple of layers of linen white sheet? Background then should meter (at the background) about the same as the subject (at the subject), but other things are possible for background, however you want it to look.
