Ok, let me show my ignorance here.
I've tried to write this several times but can't quiet seem to get my thoughts in words, maybe this time...
I'm trying to comprehend bounce flash. I've shot with bounced flash a couple of times now with my dslr and I'm sold on it...the results are very good. I'm trying to get an understanding of the "mechanics" of it.
When bouncing flash, the flash head can be angled anywhere from something like 45* forward to shooting backwards over the shooter's shoulder. This leads me to think that bounced light isn't really "bounced" but rather it's the illuminated patch of light on the ceiling/wall/etc that creates a "large light source" and thus creates soft lighting. The different angles of the flash head are simply to position the patch of light in different places in regards to the subject. For example, if shooting back over your shoulder wouldn't the angle of "bounce" send the light further behind the shooter rather than back towards the subject?...kinda like doing a bounce pass in basketball?
Man, I'm having a hard time explaining what I'm thinking!!!!<sigh> Basically, what I guess I'm asking is....is bouncing flash simply putting a large light source on the ceiling and the different angles of the flash head are simply for positioning the light source in regards to the subject? Does the light from the patch of light on the ceiling go out equally in all directions?
Now, was that clear as mud? Thanks for bearing with me!
