Rienzphoto - When you said you bounce two speedlites off the ceiling are they both together or split? Both at same power levels? And where do you place the LED, are they acting as fill?
In my working conditions its a bit difficult to answer that question as it varies from situation to situation ... but let me try (hope it isn't too confusing) ... if the room has identical ambient light I always split up my speedlites (at full power, if it is a large group of people ... both speedlites at the same power levels).
If the ambient light is different on one side of the group to the other, then I use the LED lights to bounce the LED light on the side where there is less ambient light to match the brighter side (but with the short time I have, this is never perfect, but it does minimize harsh shadows).
Having said that, if the group is very large, I do occasionally use the speedlites + the LED (all at full power) bouncing off the ceiling and worry about fixing any harsh shadows or uneven lighting in post production (not the perfect situation but given the very limited time I get, I have no choice but to deal with it in PP).
One thing I've learned over the years is that group photos are a nightmare, there are always lots of things going wrong e.g. a few people are looking away from the camera (maybe checking the bosom of lady next to them or in front
) or someone with their eyes closed, or looking grumpy etc etc etc ... so I take as many photos as I can in that short time and clone eyes (or even heads sometimes) from one image to the other.
As I work in a company that has 47 nationalities with varied skin tones, the group photos usually have some dark skinned people standing next to a very fair skinned person etc ... so I do have to use "screen" in Photoshop Layers to bring out the details in the dark skinned people. In an ideal world, I'd have an assistant, massive fancy backdrops, top-of-the-line lighting equipment etc etc, but since I only have what I have, I rely heavily
on photoshop for fixing group photos ... thank God for photoshop!
