I have used the Lightsphere II for a few informal sessions, and I must say this thing is so wonderful! The effects are "different" from what we have grown to expect in digital flash photography (i.e. the hard shadows, strong specular highlights, etc):
- shadows are now very soft and diffused, although they still appear on the left of the subject because the flash is still on the left side of the camera when in portrait mode.
- very much reduced specular highlights and "more graduations" in the skin colour. This was somewhat different from pictures taken using most conventional straight-up bounced flash, bounced flash with white reflector card, omnibounce 45 degrees, etc, and looked rather unnatural at first (since we all are too accustomed to seeing the bright highlights). However, because there are fewer specular highlights (or specular highlights with less intensity, less 255,255,255) in the picture, it is now easier to recreate the contrasty, old-school film-look which I like.
- This thing becomes the dinner conversation topic when you start taking it out and shoot people. "Wow! What is that?" and everyone likes to stroke the smooth dome...
- It doesn't change the flash metering, so don't expect it to automatically compensate for white dresses or black gowns. You have to still do it yourself. But again, because there are reduced specular highlights, overexposed black stuff now becomes easier to rescue.
- Color balance is more or less neutral. There are home-made imitations of the Lightsphere II floating out in the Internet now, but I doubt they will be as color-neutral as the Lightsphere. Also, it is the top circular dome that makes the thing work - I don't see where you can find such a dome from all your household products. ;p
- negatives: large and bulky. Although you can store the base unit together with a small lens, it takes up a lot of valuable space. Also the fitting is a little loose on my friend's SB800. On my 550EX it is ok, but definitely no where as tight as an Omnibounce.
- At ~$40USD per piece, the designer Gary Fong is certainly making big bucks out of his innovation. But being first to the market, I think he deserves the business. Disclaimer: I am in no way affiliated with him; I only use his products.
Ok, enough talk... I know you want pictures..

Remember these are just casual snaps, and pardon the color casts. I shoot in JPEG and my D30's AWB doesn't do very well in these kind of indoor situations.
