If I were to go with a flash setup what is the best way to get a decent amount of light cheap when using 35mm for portraits for play only?
Some used Sunpak 383s and slaves with homemade or used modifiers and stands would be *relatively* cheap, and would also allow you to easily pack it up and use it on location. Think thrift shop sheets, PVC piping, and foamcore.
If you can afford it, a potato masher with third stops would be a slightly more expensive, but better option. They have more power and more control than a 383. I believe the 511 is this way, but definitely not the 555, which is what I have.
Then again, some used studio flashes might be had for a bargain, and are obviously better suited to the job.
I trust you know that you have no modeling lamps with the Sunpaks. For this reason, *learning* on hot lamps is easier, IMO.
