I'm a Canon shooter and am primarily interested in shots of my daughter (2.5 years old) and my soon to be born son. Historically, I've used natural light both outdoors and indoors. I own a 430 EX II flash, but only use it occasionally and when I do, it's always bounced off of at least one wall and sometimes the wall and ceiling.
My wife recently asked if I was able to produce some of the studio type shots that are commonplace in today's infant portraiture (kid laying on a blanket that's stretched into the background, kid laying in a box, etc.). I said that I definitely could, but lighting inside of our house might be an issue as, even though we have several large windows, we have several even larger trees shading out house! The garage might be an option but only for a few hours a day and if it's cloudy, that might not work either. So, I'm looking into additional off-camera lighting.
What I'm wondering is, would a setup like this (http://www.ls-photostudio.com …-bulbs-5-photo-bulbs.html) be what I'm looking for, or should I be looking for something that's more strobe-like? The reason I ask about that specific setup is that there is someone on Craigslist advertising two of these, used but in very good shape, for less than the cost of one of them brand new. So, it seems like a great deal IF that is a good setup for what I'm looking for (nothing is a good deal if it's not the right equipment).
What I like about the idea of continuous lighting: normal sized pupils - I hate when a shot is well lit but the pupils are dilated, it looks very unnatural to me, plus you miss out on the best part of the eye; the colorful iris, easy to plan/meter a shot. One thing I'm curious about (having never used lighting beyond the external flash I own) is; is 1000W in one of these sufficient for shots with a shutter speed of 1/100-1/150, f/8-f/11, and ISO 100-400? I would assume so but I'd like to ask.
Thanks for any advice y'all can offer!
