My current lighting "kit" consists of a Speelite 420EX, on camera with a diffuser or a bounce reflector, and a reflector. By far the most common setting for me is outdoor portraits. I would like to put together a basic, inexpensive lighting kit (inexpensive being the key) to use in these situations.
I don't need anything extravagant. Basically what I am looking for is something suitable to provide a little more pop on overcast days, and to be able to more adequately deal with bright sunlight/fill flash situations as well. Currently, I spend a lot of time on a shoot wandering around looking for the best light, where the lighting lines up with the background so I can use my reflector, etc. I am thinking, some type of setup with a slave light or two, an umbrella or soft box, that type of thing. Problem is, I know absolutely nothing about any of these.
Please keep in mind, I am the furthest thing from a pro...I take lots of pics of our kids and family, and from time to time do senior pics, engagement pics, family portraits for friends, family and acquaintances. I am guessing that the requests for those may be increasing because as my wife's Facebook presence increases (she is active in the Down syndrome community) she is always posting pics I take and she keeps getting more and more "your husband took these? Really? Would he consider taking some for us?" kind of comments. So, I would like a little more advanced lighting setup than my 420EX + reflector, but I don't want to spend a lot of money on it.
). That way I can easily and quickly get it positioned where I want it and voice-command power adjustments are a plus as well
