Those GF one is not bad .. but .. spending $70 on a slurpee cup ..  and it look so weird ..  unless you buy one from AP LIU for $7

The best one I have tried, is the 80/20 diffusor ( ~ 80% bounce to the reflector then bounce to the front, the ~ 20% to the ceiling.)

Of course, the bigger reflector/diffusor, the better result, but it will use more power from your flash, and need longer recycle time, which is what you want to avoid for wedding. (unless you use external battery pack)

It also depends the location ..  if not super high ceiling ( like 20 ft plus ) and if the ceiling and walls are in white or close to white colour, then JUST BOUNCE is good enough.

Let me go home, and take some pic for different diffusors I have, and suggest you some.

Light balance is still an ISSUE .. but not that huge ... WITHOUT flash ...  

However, which flash ..  still an issue ..   as SB said ..  if WARM back ground .. and then POWERFUL flash ...  u get TWO different  WB / temp ...  which is no good .. ( unless u do it by purpose )

For wedding photography ..   you need consistency .. some .. and many diffusor will affect the metering as well ...  

I like to add "gel" to my diffusor as well .. ^_^

Yeah .. home now ..  baby is sleeping ... some free time now .. lol

Just going to go though few different Diffuser / Reflector ..

Few common Diffuser :

Right one: Gary Fong Slurpee cup ..  which actually work very well, but it just pure ugly, and big, not bad to use at home, friends' party etc.

Middle 2 : built in with flash light diffusor/Omni work well, easy to use, look factory, and accurate .. however, won't really make light SOFTER .... easy to use with bounce too.

Left : the famous SOCK style diffuser, work about the same as the omni, but with extra silver insert, and good for wide angle too ..  light, cheap, easy to use, not bad looking.

Popular small size "Reflector" :

Those are the common one, and there are much more different one .. some are in weird shape ..  I have one in "BALLON" shape as well, but lazy to blow it up, and it doesn't work well anyway.

The left one is the one I like to use most, Reflector + diffuser together, and you can change the insert as the second picture, make light really soft, great for skin tone/wedding.

Left: Bigger size reflector/Diffuser, provide even softer light and cover wider area, however, it is big in size, so many not be convenience, not that great for Show/event with lots of photographer, however, for wedding picture, if you are the main guy, or not many photographers, it is a very good tool. the down side is, will use up a lots of battery, ideal to use with battery pack.

Middle : my favorite 20/80 reflector, great for chinese resturant, (low ceiling) which offer bounce+reflect+widen light, can also add the diffuser screen, to make light softer as well, it is also small and light, very handy.

Right one : the most simpe DIY reflector, somehow, works great! just not decent looking, but basically FREE ..  you can cut whatever shape and curve to your need.

This one here, is the over size diffuser, work just like a mini soft box, ( available in different size too, but the smalll one works very similar to the Omni diffusor )
Very good result, very soft lighting, min shadow ..  however, it is just too big, and will " LOOSE " all the time ..  I pretty much give up using this one.

Catpiano

This is a silly looking one ...  but probably the best one for built in flash ..... (if you dont want to carry your external flash)

It can be FOLDED into a very small size too ..  

However, I think it looks like something for prevent "EE LEAK"  ...

King ?   

" One King 2 queen " ?  lol

Siumabb, in general, larger the diffuser (or softbox) softer the light you get ..  

You can actually COMBINED them to use .. (such as the built in flipping diffuser + reflector + screen)

I bought most of them from Vistek, and some ordered from BH.

You will found TONS of diffusers from TW .. (whatever funny shape .. even barn door, snoot .. etc .. and cheap!! lol ) however, they DON'T ship to Canada ..  SH_T ..  if you have friends in TW, ask them to buy for you.

This is one good package I got from BH :

If you mainly want the light go softer, pretty much any of those works great with the screen!!

( only come with ONE reflector, but different insert. )
