Here is what the catchlights look like:
As you can see, it produces a larger round catchlight. But as it is based on an umbrella, you can also see the light stand and the flash head in the catch light. I would probably be tempted to retouch those out. But I do like the softer/larger round catchlight as compared to the beauty dish's hard light (shown below).
The next test should be with a large Octodome to eliminate the light stand and strobe head, but I don't own one of those. Instead, I'm testing it out with an Alien Bee Ringlight and the 56" Moon Unit:
Here, I used the silver side of the Moon Unit, which has me wondering if the white side might give a more even distribution across the face of the unit. And so another test with the white side of the Moon Unit...
And we see that the white side does offer a more even distribution across the face of the unit. But still not as uniform as I would expect from an Octabank. Who wants to send me an Octa to test with? I'll even raise the light a little higher to get the catchlight into the 1 or 2 o'clock position (sorry about that).
