I'm interested in hearing from other hobbyists (pros will skew the results) who use off-camera flash: do you (like I do) use umbrellas as diffusers, or do you prefer softboxes? I've begun to become intruiged by the possibility of having control over the edge of the light that a softbox would give, so I'm curious to hear what other hobbyists are doing.
Thanks!
Perhaps you should consider advice from a pro.
Shoot through umbrellas throw light everywhere, which means you will get reflections from colored walls and objects that will color your light. I use them only to raise ambient levels in large rooms/halls, usually when I am the official photographer for an event. Best used with strobes that can punch with power.
Reflective umbrellas throw light forward; silver ones can be harsh, white ones softer. I'll use small ones for back lighting when shooting at events, especially when shooting food.
Covered umbrellas throw light forward, but provide much better difusion and softer light. I use these frequently for location portrait or food shots because they are easy to set up. I like the Photek Softlighter or Buff version. For truly portable work, I have a cover for a Westcott convertable umbrella (43"). They are shallow, so work well in tight spaces.
Similar to the umbrellas are the Octaboxes; they are deeper, provide more uniform light, but take up more space. You can get grids for some, which adds to their ability to control light. One primary advantage of the covered umbrellas and Octaboxes is that the catch lights (reflections of the light in the eyes) are round. That's why I like them for key light.
Softboxes can provide better light control, if they have recessed diffusers and especially if they have grids. Cheap softboxes without recessed diffusers are like umbrellas, although they do have a slightly more defined edge. Softboxes can run from square to strip (narrow rectangle), common size is a 3:2 ratio (e.g. 36:24).
Classic softboxes and octaboxes can be difficult to set up. I use quick release speed rings to help set them up, so I can set up a 7-foot octabox very quickly. There are some quick setup boxes; I have several that just fold out. They take up quite a bit of room, which is a minus to their portability. Umbrella style boxes can be set up quickly; they are not as durable but are generally very cheap. Westcott Apollo series are examples which I use frequently; they do have limitations on tilt which can be solved by using adapters or boom arms. The lights are inside the box, so they work best if you have remote power control for your lights.
I use all of this (just not all at once) depending on the look I want, location I'm shooting, how portable it needs to be, etc etc etc.
If using a speedlight rather than a strobe, you will want the flash further back than a large covered umbrella will allow. Umbrella style softbox is a good start; Westcott Apollo can be gotten in kits with grids. Get the newer ones with fiberglass spiders.
