I have used a lot the Stoffen omnibounce, but for my 5600 I decided not to buy it and use the "better bounce card" home made. Here is a shot taken with it and my KM A2. You can see the shadows in the first one, but it works well for me


1/30, f3.2, ISO100. 81mm equiv

Another one:

1/160, f4, ISO64. 46mm equiv


1/125, f4, ISO64. 90mm equiv

Cheap, simple and very good results with this bouncecard, there was a video explaining how to make it.

Hi

Now, that is a good question I don't know a definite answer even after quite some trials...

- I have the standard Stofen, but I am only half-happy with it. Can still produce pronounced shadows.
- then I tried some inflatable diffusers, which, by having a greater surface, I hoped would make less harsh shadows. Well, with the Stofen together, it improves a bit.
- a self-made bouncecard I used, too. Not better than the Stofen, I found.
- still the best thing I did is using a small (80cm) white reflector, meant for reflection, but useable also for transmission... that makes for a perfect smooth light. Not very practical, however.

So if somebody knows the definite answer, I'll be glad to hear, too...

I just did a wedding with Gary Fong and was impressed. The church that was used had a wood beam roof (was not white). If I modify it I might put some tinfoil in the back so not to whaste so much light.

I use Fong's clear lightsphere as well. Once I got used to the silly look of it I learned to really like it. Works very well in most situation and seems to be the most versital diffuser I've tried.

wass

I do as Gary suggests and shoot with the flash head rotated 90 so that it can easily be changed from horizontal to vertical shooting. I cut a wedge shaped piece of photo paper and put it at the back of the clear lightsphere to not waist flash power to the rear. That alone seemed to give about 1/2 stop extra light. He also makes a new "kicker" dome that has a reflector on it to force light forward but that's more for the cloudy sphere not the clear that I like to use.

Though, I may pick up a cloud with the amberdome as it looks to work nicely to match the WB.

I do use an Ice-cream-box in which I cut a hole to put my flash in and inside I put some alumium-foil (is this the word in English?) off course not in the front which has to do the "diffusion job"

Here it is discribed p 69 (it is in dutch but I think the pictures are clear)

My favorite bounce/diffuser is the LumiQuest Pro Max system. It incoporates a LumiQuest 80/20 and has a white, gold, or silver insert you can quickly insert in it to manipulate the light results. You also get a fully opaque soft plastic diffuser that goes over the front reguardless of the inserts or not. The 80/20 without the inserts allows 80 persent of the light to go up and bounce whilr 20 percent goes forward. This works a lot like Gary Fong's Lightsphere but folds up flat and fits in a nice vinyl wallet that easily goes into your bag. The part number is LQ-931D. More info at LumiQuest.com..

This thing really works great on my Sigma 500EF DG Super amd Vivitar 730AFM with the A100. Highly reccomend this one. Aaron

i like the better bouce card a lot. use the curve forward for more distance or wide shots. flip it backwards when im shooting close to people. i usually just double up on pieces of paper and rubber band it on. this is one, bit bigger because i was shooting real estate and had to kick more light forward.

Look here, almost end of site: Lightsphere sizing/self sizing chart, here you can look up the sizes and measure your flash...
The problem is that he provides different sizes for the same flash, strange. So I would calculate it myself.

I've used the Stofen Omnibounces. For those who find that you don't get enough diffusion, try stacking two of them. I did that and good pretty good results. I've also heard second-hand accounts that stacking a gold omnibounce with a white one can produce some very nice results for portrait-type work.

One seemingly underrated diffuser/bouncecard I used was the Stofen Two Way which can work as both a bounce card and a shoot-thru diffuser. I lost mine a while back but I had more consistent exposures with it vs. the Omnibounce but never got to compare it to stacked Omnibounces.

Anyone here used a Lumiquest mini Softbox? I saw it in Kiklop's kit and was wondering if anyone else has used it, and can share their experience with it? Been thinking of using it with my 3600HSD.
