Light modifiers – umbrellas (part 2)

This second tutorial about umbrellas explains a shot using the same 42″ umbrella as before, but this time in reflective mode.

For the following photo I used the 42″ convertible umbrella again, but this time in its “normal” way — to reflect light.  First, here’s the photo:

In this case I decided to use it reflective, because I wanted to have a more distinct hotspot to emphasize her face and to give her blouse a touch less light. This could be also done by partly flagging a translucent umbrella, but I went that way.

The flash was positioned directly in front of the model and slightly over eye-level with a distance of about 3 to 4 feet to my model. I shot from directly under the umbrella, the camera tucked right to the flash stand.  The close distance is obvious looking at the very soft shadow under the nose or under the chin. A huge difference to the quality of light from the previous tutorial, but still the same umbrella.

The colour comes from a green gel attached to the flash. I set the white balance to match the filtered flash, which shifted the evening light to a rich magenta,  intensified by underexposing the ambient by about 2 stops.

Here’s another example of the same set-up, but I moved the flash a wee bit to the left:

    should have ironed the white shirt and had her wear an undershirt that wouldn’t show through, bro

      Ioning knitware wouldn’t be wise and wearing a semi transparent top to me doesn’t make any sense if you put the same colour underneath… ;-)

        I agree, the shirt is supposed to be wrinkly. The black under-tanktop is good to show the see-through shirt.
        Good tips about using a green gel. I should experiment with different gel colours more.

    White shoot through umbrellas have an even more pronounced hotspot than reflective umbrellas if used close. When used a long way back (as per your previous example) all umbrellas perform similarly.

      Hi Leo,

      I would disagree. You don’t have such a pronounced hotspot with shoot throughs and (here nearly more important) you would have a very even fall off, which would put more light on the white shirt. From a distance most umbrellas work similar, that’s right. But they still differ in specularity!

        I agree with Martin. With same flash power, less light will bounch back from a shoot through than a reflective.

        What I call a hot spot you call fall off…

    I really like this technique but I’m having some problems with the use of the color gel to create the opposite color in the background. I tried this using a purple gel, with the idea of turning the background orange, which worked in camera, but I can’t import the image into Lightroom. It looks like the in-camera white balance is beyond Lighttroom’s 2000K-10000K limit so I’m not able to set a white balance which leaves the model ( lit by the flash) looking correct. Any ideas?
