A photographer through experience and not schooling, my biggest challenge is always lighting. I shoot portraits - families, seniors, and children; mostly on location and outdoors. Also many school sports teams and individuals. I do a bit of indoor location work also. I have a Canon 20D, and mostly use my Canon 550EX speedlite as fill-flash On my stroboframe. 1: I would like softer light for fill - thinking about purchasing a Westcott Micro Apollo Light Modifier - will this help? 2: I need more light for some large indoor shooting. I was considering a monolight kit, but would really prefer AC/DC for portability and they are expensive. I have a rarely used Sunpak Auto 552 Thyristor with all the bells and whistles and am trying to make that work using the remote sensor to make the Sunpak a slave. I can't seem to get enough light in the photos no matter how I set it up. Is the Canon 550's preflash messing me up? Would a wireless transmitter/receiver help? 3: IF I use the Sunpak, the light is harsh, and I would want to soften it. Instead of an umbrella, would a Softlighter II or other type of softbox work with the Sunpak 552? 4: I also have a Quantum Turbo Battery but it doesn't seem to work well with the Sunpak - (slower than when using AA batteries!) I have been reading/researching online for hours - and keep coming here - an incredible source of information I guess I am looking for an inexpensive PORTABLE studio - any ideas?
