What is so good about Gary Fong's products anyway?
That's pretty much the essence of my question...
Well, I watched the Gary Fong video linked above, the one where he has the model use the remote, and she snaps a photo of herself with each of the modifiers, as Gary runs the camera and swaps the different modifiers in and out...as one can see from the comparison photos, the Fong Diffuser casts the lightest, least-dense shadow behind her. She's placed VERY close to that white wall, and the shooting area has a nice, white ceiling. Just based on the shadows alone, we can see that the Fong Diffuser in that test is throwing out the MOST-diffused, and the LEAST-directional light pattern of any of the tested modifiers. WHich again, goes right back to the exact kind of use I think it's intended for: smaller rooms, low ceilings, cramped situations.
When Gary got started selling these things, I think his MAIN client base were then-new wedding photographers, and these people tend to shoot a lot of before the wedding stuff in low-ceilinged hotel rooms....bride and her attendants getting ready, groom and groomsmen getting dressed...you know, very standard stuff with a single flash, ON the camera...and the Fong Diffuser creates very soft, diffused light, spreads the light all around, and creates a LOT of shadow-filling, softened light by way of reducing the directionality of the light from a speedlight's Fresnel lens...
I watched his on-the-street video comparo of open shade, versus a monolight with an umbrella, versus the Fong Diffuser on an SB-910, photographing a standing model on the sidewalk, with bright, California-type sunlight on the street and opposite sidewalk behind the girl. The umbrella-lighted shots looked like, well, umbrella light. The FOng Diffuser was obviously a smaller source, and created some specularity on her skin. The open shade shot produced a blown-out background, and FLAT, dull lighting on the woman. By bringing LIGHT into the shaded area, both the umbrella shot and the FOng DIffuser shot allowed him to make the sky blue by bringing the delta between shade/sunlight down. So...you know...basic lighting 101 stuff.
It's a modifier. It does what it does. Used in the RIGHT locations, it produces good lighting, when the need is
to create diffused, omni-directional light. Of course, a lot of people don't seem to understand how to actually light ANYthing, so they ridicule the tool because they really don't get the concept of ambient spill versus directional light. It's only ONE kind of a tool...we don't bash a hammer because it's not a socket wrench, and we don't bash a box-end wrench because it make a crappy hammer and an even worse pry bar...
Diffused, omni-directional light: hotel rooms, apartment rooms, inside of boats, motor homes, RV's, camping trailers, cramped rooms of all types, or for when flash with
soft, open shadowing is desired. Jeebus...that's what it does...
