If you want to take your flash photography one step further, the next thing to get is a secondary slave unit that fires off simultaneously with your main flash. Why? Because a single flash unit often won’t suffice to illuminate a whole scene. However, since a good speedlight easily sets you back $100 plus, you may not want to shell out that money right away. That’s okay, though, because B&H is now featuring a new series of slave flashes that come in at less than $30 each.
