Which is why, at least for now, I'm digging the Apollo umbrella style soft-box from Westcott.
I just got an Apollo-style SB which I can't wait to try soon - it's bigger than any of my other modifiers at 2x4' (although I believe that's about the equivalent of the 45" Photek, the shape will mean I can do different things with light falloff on shoulders depending on how I position it. At least that's what I hope!).
Thanks for the article, Charles! I do find it interesting they would use a parabolic for the comparison, since most people wind up using your basic shoothru or bounce version initially. As I understand it (and do correct me if I'm wrong) parabolics distribute the light in a very different way, and are much brighter, meaning a significant difference from the look a SB gives than, say, an ordinary white shoothru.

I have had clients ask about it when I have done shoots with both and they see the catch lights...it was years ago, but that made me go to umbreallys only...now we do have oct. SB's ... which could be an option ... ... ... but they take up more storage room also..
Yes ... YES .. you are so correct ...we are our own worst enemies ... ..
Umbrellas:
Silver ones deliver pretty much 100% output and, in some cases, can focus the light thus delivering more light that a bare bulb (I'm not talking about a bulb with a good parabolic reflector) in a local area.
Spillage is moderate.
The white ones do tend to lose at least 1 stop (if not more) and spill like crazy. The only thning worse spill-wise is the brollybox (shoot-through umbrellas)
Parabolic umbrellas, though more expensive, deliver higher quality and less spill. I have an 86" Paul Buff's PLM and it's a total joy to work with, espcially on location (indoors):
And yes, as Diva mentioned, outdoors they fly away like there is no tomorrow...
Softboxes:
while some light loss is inevitable due to (usually two) diffusion layers, the light quality is hard to beat and the spillage is minimum, especially if you put on a grid. Naturally, the quality comes at a price and a certain (but not over the top) complication during the setup.
As for the shape of the catchlights... To each is own. I personally prefer rectangular ones since at least they imitate the window shape. Round catchlight is a single tell-tell sign of the artificial lighting, and there is nothing round in nature - except, naturally, sun and moon, but neither produces anything bigger than a tiny spec where the shape is undistinguisheable.
The only one catchlight shape I personally hate with a passion is a donut shape of the ring flash. But that's just me :-)
Since I shoot speedlights instead of studio strobes, it's GREAT that there are finally so many options for smaller flashes now. Sure, it's fun to use the big kid "real" strobes, but in my home studio space speedlights are not only cheaper, but WAY more practical both in terms of footprint and power (or lack thereof). David Hobby really started a movement going, and it's nice to be able to benefit

Cool product, but $200 for a 32" x 40" is definitely an "excuse", at least for me. I leave mine assembled and put them in the back of my truck.

There are lot's of things in studio lighting gear you may need to get BEFORE or INSTEAD OF getting an octabox. OB's really just another modifier, not a mandatory angel of the totem pole.

Pop it open, put it in the slot on the stand and good to go...if the wind blows it over it will bend...I can unbend it a couple times before I need to replace it. Another $40.

At any rate I prefer to work with bare (gelled) flashes outdoors for the following reasons:
