It might be useful if, for each configuration, you took meter readings at three locations: direct center, then maybe your -50 and -18 points. While the images are helpful to demonstrate the falloff pattern, raw numbers would really illustrate the impact it has on lighting a scene.

I'd also love to see a test like this measuring the falloff over distance, rather than laterally, at a consistent power setting. I'm sure that a lot of photographers using hotshoe flash diffusers are concerned with the depth from the source that they can reasonably illuminate and how much output power it'll take to get the results they need.

+1 on metering at a couple of spots. There was a youtube video of somebody doing
this with that new parabolic reflector from Paul Buff - quite enlightening (no pun
intended).

It would also be interesting to see how Chuck Gardner's foam bowls do when stacked
up against these as well...

Best,

All of your reviews are excellent, and the clear pictures are top notch!

Thank 400d! I appreciate the feedback!

@ shatterkiss, rkgatteleport
I agree with you. I'll try to allocate some time to do the measurements.
These tests are all about the visuals.

Another request to see Chuck's Gardners foam DIY option included in this test !!!

You drove traffic to your site with a post on a subject that is very interesting and well done ... but this site is VERY aware of Chuck's option !

FWIW - Here are a couple shots taken at 10mm on a 1.6 crop 20D with and without the foam diffuser for comparison which are on the page with the template: http://super.nova.org/DPR/DIY01/ along with some other more examples of typical results.

Its also worth noting that I usually use the diffuser with two flashes in an key / fill configuration and getting even lighting into the four corners of a room or flat wall is near the bottom of my priority list. I'm more concerned with the lighting on the foreground and more often than not darken and soften the corners of my image to create contrast with the sharper, brighter stuff in the middle.

Nice review. If an update is due, I would recommend you to include Strobella, a small umbrella diffuser I am very happy with.
