So I bought this cheap optical slave bounce flash made by Digital Concepts on eBay brand new for $26 because it is also hot shoe mountable.. I wanted a better one than the $15 Quantarays I bought that I haven't had much luck with.. This flash is a bounce flash resembling a speed light, but it doesn't talk to the camera. It even has the red lens on the front that my SB-600 has, but has non of the capabilities of the SB-600. It's just an optical slave, and it cycles fast due to the 4AA instead of the 2 AAA of the Quantarays. What I was really amazed at is that it fired every single time I took a picture, and I was only using the on-board flash.. Even inside the basket you'll see and facing sideways.. This is my first time playing around with a very responsive slave, and I can't wait to do more.. I know these pictures all suck, but I haven't edited them, and I haven't any idea yet how to do this type of photography effectively.. I will, though.. These were really fun: 1. Some bowls in my kitchen-I placed the flash in the middle bowl 2. In a basket 3. Behind a radiator 4. In one of my CD towers 5. 6. 7. 8. I asked my daughter to hold it on her lap 9. My wife was doing something with my baby on her lap, so I set the flash on the table in front of them. 10.
