While I was out shooting Santa last week I had some spare time to play with my flash and shoot through umbrella set-up and took the following shot:
As you can see there is a distinct hotspot in the umbrella. Not so great for even distribution of light, which is the point of the umbrella to start off with. Of course it does help to distribute light, but not as well as it could. The flash was set to about 50mm here, so I flipped out the built in diffuser and it automatically went to 14mm wide with the following result:
Beautiful even distribution of light resulting in a better wrap around effect for portraits!
The light stand used here is in fact a junky old cheap tripod with the head removed and refitted to an extension pole which I then mounted to the top of the junky old cheap tripod, I then drilled a hole through the plastic head (taking care to avoid anything important) and voila! Nice tall light stand for the man on a limited budget. Here is a close up of the head:
Some people say I'm tight, but I like to think of myself as frugal...
