factory diffusers 600ex-rt

modern flashes with zoom heads are amazingly accurate. The angle you show in the first diagram could not be achieved without the use of the drop down diffuser, even then I don't think it would even be close.

that ^^ page gives an angle of view calculator. Modern flashes will give a slightly larger angle so that the coverage is full and a bit more even across the frame.

Your photo was shot at 28mm. The calculator shows a vertical angle of view of 46.4 degrees at 28mm. Lets say the actual coverage is 10° more, 56 degrees, red lines:

Not exactly sure what your photo is supposed to illustrate, but i am guessing that if your flash was angled at 45° most of the light from the flash falling on the table is being bounced off the ceiling with very little being reflected from the tiny white card. Otherwise, with direct flash, your fall off across the table would have been greater.

No the flash was at 90 and most likely on a bracket. While I may not feather I never bounce forward because I have to worry too much about angle and distance to subject. I guess I was showing an example what you said. The front of the table was near blowing out while the people were under exposed.

It is not a diffuser. It is a bounce card...

not exactly THIS model, but it sure doesnt look like any "card" ive ever seen. thanks for clarifying this for me!

...He may have been 'paid' but he did not know his craft!

hmmm. do they give out SI credentials and State Department (FedGov) access to just anyone? he certainly LOOKED like he knew his craft...

i didnt see him shooting the check holders but he was playing around with a DIFFUSER on his flash and when i DID see him take a couple of shots, the flash was pointed 90o off lens axis...

thanks for everyones imput...

that is what is generally known as a Sto-fen type diffuser. Sto-fen is a brand name, but there are plenty who manufacture them. It is not a factory accessory, at least for Canon flashes, some other's may come with them. I think your use of "factory" is what got people thinking it might be the white card that is built into articulating speedlights. No big deal though.

the stofen is often referred to as tupperware around here, and is not very highly thought of, if you hadn't figured that out already.

it's use while standing in the middle of a field is a complete waste of battery power regardless of the angle of the flash head. Well, unless maybe the guy broke his build in bounce card and wanted to get as much height as he could from his on-camera flash.

Not what I thought you were taking about it really isn't a diffuse either. Still a small light source. It it is a bounce devise that will through light all over the place. Ceiling, walls, furniture, floors. Would have been better off using LHB's method with the bounce card instead of lighting planes.
