Flash gun query
Why is it that when you mount you flash gun on a tripod it is not as effective as when it is on the camrea?
I been trying and experimenting flash guns off camrea so i lent a light piece of wood against my garage and took a few shots with the light in the back ground and the flash off camrea and on a tripod using wirless trigger. I exposed for the sky but my subject(wood) is dark still but when i mounted the flash on the camrea and went to the same postion it produced much better results. Oh forgot to mention the flash and camrea settings was the same as they were both on manual.
Can any one help?

You are using a Canon 50D and what flash? What kind of wireless trigger? Is the flash aimed accurately? Is the flash zoomed to the same focal length and is the flash the same distance from the subject?
If you take the flash off the camera but leave it immediately above the camera or just put a thin insulator in the hot shoe, between camera and flash, what is the effect?

What flash were you using? If it was a model that adjusts beam width for focal length then off camera it probably defaults to wide angle, while on camera it may narrow the beam (which intensifies power slightly) according to the focal length used. Assuming the flash was aimed correctly, flash to subject distance didn't change, and flash and camera settings didn't change, I can't think of anything else that would cause it. My flashes, cheap ones and expensive ones, all work the same on or off camera.

i am using 50D and the flash is 430 exII. i kept the flash on manuall setting and the camrea on the same setting in each photo. I also took the shot with the flash in the same postion. The wireless trigger is a blazzeo.
I uploaded 2 pic 1102 is on camrea and 1101 is off camrea. - Attachments:

The high shutter speed is the problem I'm guessing. High speed sync doesn't work with most wireless triggers. I am not familiar with the Blazzeo, but if it's not one of the top end remotes it probably won't sync faster than 1/250th on your 50D, and it might not even sync that fast.

For those of you following along at home, the shutter speed for both sample photos was 1/1600 th!
