    Hi boss, my words are from my own dictionary and nothing to do with azone's diagram. Just using his illustration in showing how the light moves when using an omnibounce.

    What I'm trying to say is that, omnibounce softens the light output as compared to direct flash, and there is a difference in the final output between direct and bounced flash.

    Of course, I might be wrong...

    If anyone can understand this, he/she will understand why omnibounce don't work well in open areas (bounce card works better in open area than omnibounce) and why LS is better then omnibounce.
    Yep... catchlights got it right, I agree with him totally. The omnibounce/LS/LSII are all diffusers.

    I tend to shoot more in indoors environment and own a stofen omnibounce.

    1) Has anyone compared the difference in the effect using the omnibounce compared to a bounce card? Assuming ceiling is low enough for bounce flash, which will produce a nicer picture?
    If ceiling is low enough, I don't see the need to use an omnibounce or bounce card, just point your flash head up to the ceiling. It produces a very even and nice lighting to your subjects.
    I have encountered a situation where the ceiling is low enough but it is coloured. No ceiling bounce for that situation.

    It all depends on whether you are shooting film or digital. For film, I have no problems pointing directly at my subjects. For digital, it helps to point 45 or 60 degrees up, so u don't "burn" your subjects. As mentioned above in Qn 1, there is no need to use an omnibounce if ceiling is low.
    I do not have any problems with that, my digital body handles flash exposure pretty well. No prizes for guessing which make I use.

    Quote Originally Posted by vivientan

    If ceiling is high, the bottom half of your subjects can get underexposed, so there's no point using an omnibounce! Omnibounce actually reduces flash power by 1 f-stop (if I remember correctly). Using a bounce card works for me in such situations. As for the height, there's really no hard and fast rule on a distinction between high vs low. It all depends on the GN of your flash, flash compensation etc. You will have a better idea with trial and error...all comes with experience
    Thanks man!
    Omnibounce is made in such a way that when you point 60 degrees upwards, a portion of it will still scatter light in the direction of the subject. You will still get some catch light although most of the power will be used in illuminating the surrounding. If your shots have the bottom half underexposed, you probably have not understood how the omnibounce work and use it to your advantage. You can tilt the head down to 45 degrees if that happens.

    So to summarise,

    Technical aspect
    Direct flash - like shining a torch
    Flash card - diffuses 180. $8 or make your own.
    OB - diffuses the light 270. $40. cool factor.
    LSII - diffuses light 360 more evenly cos of shape of sphere $89. ET comes home.

    Common situations you can apply flash...

    1. Outdoor - use direct flash (if necessary). doesn't make sense to use a diffuser.

    2. Indoor low ceiling e.g. goodwood park, hyatt - use direct flash bounce off ceiling. light falls evenly with illuminated background. angle depends on how far your subjects are. don't forget to watch out for mirrors on ceiling (don't ask me why there are mirrors on ceilings)!!

    3. Indoor high ceiling e.g. ritz, four seasons, fullerton, marriott, grandcopthorne - use direct flash with OB or LSII e.g. table shots at wedding. if subject is not covered halfway by table, use LSII.

    4. Indoor portrait - use direct flash with LSII

    5. Indoor with subjects at a distant e.g. fashion shows - use direct flash with increased intensity.

    also equally important is to understand your flash. e.g. ettl, second curtain sync, intensity etc.

    PRO mah.. As long as PRO anything also can one.. What is logically not possible to common people like us is possible to them.. I have not reached that stage yet.. so please don't comment my shots as PRO shots. I need effort to shoot those, try and try until get it... Not like PRO.. Pray pray a bit can easily get those what we think is impossible shots, one shoot one kill somemore... Looooonnnngggg way to go for many of us...

    What I think of LSII since you say that it illuminates 360 deg (I haven't used one). You lose half the amount of light illuminating things which don't need to illuminate. And I think it might only be useful when you're using Metz 60-series.

    Wah.. I dowan to be PRO leh... I still cannot accept myself shooting rooflessly (make that ceilinglessly) with omnibounce at 90 degrees. Only thing I can think of is to use it to trigger slaves with minimum effect on the subject.

    So funny meh?

    One or two months back, I saw a cosmetic counter hire someone set up at studio light to shoot a makeover, at the same location you mention, one light set up, with reflector place beneath the subject, the studio light (I think is a 500w mono blk) also point upwards..... OMG!! my ex 4k flash head also not that powerful to do that!!? really amazing!! this is a set up that I can't find in any studio lighting books....

    Nope... Metz 60 series don't need omnibounce or diffuser or whatsoever... it's good enough alone

    Some posts in this thread mentioned that there is almost no difference between direct flash and omnibounce at open area.

    But I have the similiar opinion with espn. The omnibounce at least can soften the light.

    Can anyone give comments on this opinion?
