After a recent portrait photography session I paid for where I thought all the images were of poor quality I decided that I wanted to be the one taking the studio portraits and getting the emotions/expressions to come out of the subject.
I've been recently more lights (either flash or strobes) for a while now, wanting to get a blown out background look of people but full body portraits not just headshot or body.
I'm not sure of
1) should I go fkash guns like yong nuo or should I get strobes which require mains. Reason being is matt granger did a video showing that 4 X flash guns was about 400w strobe. and this is supported by another video where the person used a light meter on both and a single flash gun metered at f11 while the strobe metered at f22.
if anyone can help me on this argument I'd appreciate it.
from what I can see 1 X4-500w strobe is $500 which is almost the same as 4x95 yong nuo flash gun + triggers for each.
as an example I want to be able to achieve this image - one taken of me in a studio at studio olympia.

It was suggested to me today that 4X4002 strobes could do this in a high key setting with two at front and two at back with umbreallas. the lights would cost 2000.
oh and ive heard you can get 1000 3000 and 5000+ watt seconds strobes, not sure how much power I would need for a photo like below to completely blow away everything. but would love to be able to replicate that image.
