New DIY bouncer/diffuser (lumiquest-style)

• White craft foam + silicone rubber band.
  
• Goal was to raise and spread direct, unbounced flash
  
• It bleeds a little to the ceiling
  
• probably does not have great evenness of coverage

How about getting a black fun foam for covering the back side?

How about getting a black fun foam for covering the back side?

I have some black foam, but I didn't use it for this first trial pattern.

What I'd really like to see are the measurements of the lumiquest pocket bouncer so I can see what pattern they use to put the whole of the light going forward.

The hardest thing is making sure the 4-sided trapezoid of light coming up from the plane of the flash head hits a flat white section of material at 45º to where we want the light to go. My bouncer is very curved, so the light coming from the right and left sides isn't necessarily going to go directly forward. This is why I think my design won't achieve very even distribution of light.

The reason why I've always favored the following DIY foam diffuser-reflector (revised version of Chuck Gardner and others before him) is that I can control the forward or upward direction of the light. The "ceiling" of this DIY is designed to close all the way down or all the way up to vertical position. When it's all the way down, all the light goes forward (for no-bounce situations, such as outdoors or indoors without friendly walls or ceilings). When it's all the way up, most of the light goes upward (or sideward depending on the flash head swivel position) for bouncing purposes.

I'm planning on making a larger version (12" in height as opposed to 9" version you see here). Although the 9" version here seems (so far) to eliminate the need for a cumbersome, heavy, and expensive flash bracket, I wanted to create the 12" version just to compare and see. It's so cheap to make one anyway...

Another thing...

LumiQuest isn't that expensive, so why not just buy one? I'd have purchased one if it weren't for the fact that I like my DIY's design and functionality better. That's just based on my preference and not based on any "side to side" comparative tests. I could be wrong, but the size of the LQ bouncer seems to require the use of a flash bracket for maximum result, and I'd much prefer to do away with a flash bracket.
