2. Slave flash

Following last nights class, here is a link to a cheap flash slave sold by Jessops.  The slave units on this page are a bit more expensive but more robust and reliable (the one I brought in was the third one down).  Here is a cheap  flash gun sold by Jessops.  If you are using a digital SLR your camera’s manufacturer will probably have a dedicated flash for your camera, these are expensive but far more flexible than the cheap Jessops model. If you are choosing a more dedicated flash choose one which allows the flash to be pointed and nearby walls or ceilings.

Modern cameras use a lot of cleaver tricks to get exposure and image appearance right such as a pre-flash to check exposure or remove redeye before the actual exposure. This will usually confuse the slave flash and the exposure will not work. If you can switch off redeye reduction and use the camera in full manual mode. This process might be a bit more complex with Canon cameras, I have put a link to a Canon forum that explains a workaround.

This link covers the benefit of off camera flash slave flash. This page is a bit more technical but it does still cover some useful stuff.

DUE TO MANY CAMERAS BUILT IN PREFLASH /REDEYE REDUCTION I RECOMMEND YOU TALK TO SOMEONE AT A CAMERA STORE ABOUT YOUR CAMERA AND AVAILABLE FLASH EQUIPMENT BEFORE YOU BUY.
