Super-flash tests

This afternoon I decided to put the new "mutant" flash through its paces to see what it could do .
I fired it about 15-20 times all together without giving it much time to cool down .
I took a few shots to compare it to the SB800 on full power .Ignore the background getting brighter , it was raining and the sun was coming out again . Concentrate on the foreground and shadows .
I used the D50 because it can sync flash at any speed .

I had the "super-flash" on half power which was half the capacitors in the original flash plus the 3500uf cap I added .

Then I moved up the driveway to really put it to the test ....

I then moved to the top of the driveway . And tried at 1/3200th sec .

I would imagine the flash tube will last as it doesn't appear to have suffered any side effects .
"Full power " is when the other half of the capacitor bank inside the flash handle is also connected.

Extending the SU800's "angle"

For some this may be common knowledge but today I was doing some experiments with the SU800 outdoors .
I had the SB800 on a stand behind me in remote mode firing at 1/128th power and kept changing the angle of the camera until it would no longer fire .
When they were both pointing toward that fence it fired every time even with the flash behind the camera - maybe it was bouncing the signal off the fence ?
Anyway I reached an angle when the SB800 would no longer fire ...

You kind of wonder why Nikon would make the trigger system facing directly forward which is the last place anyone would have their lighting .
Then I added something to the equation , without moving anything , which made it fire again ....

I had tried simply placing my finger in front of the SU800 and that worked , the signal bounced off my finger and triggered the flash behind the camera .
I just added this little white object in front of the SU800 which bounced the signal backwards and made the flash fire every time .

I see possibilities here , for the SU800 and SB800 , I think I could design something that attaches to each of them to send and receive signals from any angle - or at least increase their reliability in some situations .
