Hello There,
I just got my first speedlight a couple of weeks ago--a Yongnuo 468 ETTL II and I am completely new to the concept of flash photography. However, I've been reading a TON about it and have practicing here and there when I have the time. In 3 weeks I have my first ever paid gig (zoinks!) and I am pretty excited about it. A guy is graduating med school and I am shooting him and his wife for a couple of hours in a park during the afternoon, and then at their nighttime party inside a private room in a nice hotel (think small bar/lounge kind of thing). I might end up taking some shots of them at night, standing outside of the hotel on the city sidewalk. I've spent the last few hours reading about light modifiers such as the Lumiquests, Demb and other such strap-on diffusers/bounce card thingies. What would one essential accessory be in your opinion to improve the experience? Here is a breakdown of some various factors:
-Camera is a T2i/550D
-50mm 1.4 lens
-28-135mm 4-5.6 lens
-Flash will always be mounted to the hot shoe; no remotes, cables etc.
-I shoot RAW
-I will be using ETTL
-Daytime in the park I guess I will just be using fill light, which from my research I don't believe I would need any form of diffuser or anything
-At nighttime, I will be inside/outside, ceilings/no ceilings
So what would you slap on the flash (if even anything) in this scenario?
And.... is the 28-135mm not going to work well for this? There will be single person shots as well as some small group stuff.
Thanks,
Randy
