OK, the gradations of the shadows to the right of her nose are ever so slightly softer in #2, the transitions more gradual, and I suspect that might be the more even illumination coming from the bare bulb D-Lite 2 inside the softbox. Then again, it might have the opposite effect! If I had to bet a dollar... I'd bet on #1 being the Speedlight! :)

That said, there's nothing between the two, you will never see the difference in real-life shooting.

Hi Rudi,

Since no one else wants to play along, it's just you. :D

Unfortunately your guess is not correct. #2 is the Speedlight and #1 is the D-Lite.

What I neglected to mention was that when I used the Speedlight I added my hot spot reduction mod to even out the light, and your observation confirms that it did in fact even it out. Interestingly, I think it's actually more even than using a strobe without the hot spot reduction. I'll have to test tat further.

Other than a slight loss in power I'm convinced that using modifiers of this size is still relatively efficient and not a waste of power as some have intimated. Obviously, using flashes of lower power changes that so I'm only making reference to units like the Nikon SB-800, Canon 580EX (II), Quantum or other high powered flash.

Welcome to the club with the same conclusions!!!

Like I said in my previous post, any differences would not be seen in real life - a live model would not sit perfectly still for a start! :) And I wasn't 100% sure how the light would be shaped in either case, so I took a stab at it. I'm glad I could notice the slight difference though, and since I was the only one playing, don't I at least get the "Participant" ribbon?? :D

thanks for all the info, TMR. here's what i came up with today for mounting my vivitar 285s with the ebay gadget infinity triggers onto stands with an amvona softbox. you can also see the AA battery modification i did to the triggers. i hope this helps someone else with their project like yours did for mine.

Hey Benjamin,

Looks like you came up with a solution that works for you as well. Nice job.

With the help of another well placed hole (in between the 2 flash shoe's) in the bracket and a low profile knob with a 1/4"-20 thread the bracket has greater functionality.

Originally I made it so it could fire a shoe mount flash in to a softbox using a standard speed ring. Since I knew I would also be firing the flash in to umbrellas it only made sense to use the same bracket.

Adding the extra hole in between the 2 flash shoe's gives me a mounting hole to attach it to a spigot and lock it in place using the Bogen 2905/026 umbrella adapter. This lets me use an umbrella with the adapter and have my flash and Pocket Wizard mounted on top.

Using this one bracket (of which I just cut the materials for a second one) I can have a flash and Pocket Wizard firing in to any form of umbrella or softbox/octabox I want and I no longer need to use the cheaper, flimsy Photoflex bracket and plastic speed ring. Those parts can now go in to the "Parts for potential DIY's" bin. :D

Here is the bracket shown mounted to the Bogen 2905 with an umbrella attached.

Nice job Robert. Definitely a DIY to add to the list.
