I'm posting these here 'cause I want to put a link in the lighting "Sticky" & I know that you guys will have some good suggestions. So feel free!
This turned out to be "simpler" than I'd intended!
I like to travel light & I used the #2 since the title could have been either "Two light portrait" or "Too light on the light -stands portrait" as in I forgot my frackin' umbrella & my other cousins daughter Kelly expected to have some pictures taken, so what do you do? In my case, I just had to find a way to take them.
Solving the lack of an umbrella was easy as I had an extra piece of 30X40" art board that I'd intended to use as a flag. Problem was that I'd intended to mount both the strobes and the quartz "modeling light" on the same stand, so now I was one stand short. Which is why the tripod was "standing-in" for the missing light stand. (Don't do this in front of a client!)
Not everyone has a bag full of light stands, so I had planned to put the background strobe on another chair.
The 2 strobes are some very old & very cheap Spiralites that I bought to carry along with my Vivitars when I flew out of town. I think I paid about $30 each. Maybe less. I've seen them go on eBay for $6.
1S. The "set" without the main bounce cardboard in the way of the light stands. (One strobe has a 1ND gell still on it from another shoot.)
The white background is a roll of plastic tablecloth. A "proper" exposure for it was f/8 so it was over exposed about 1-1/2 stops. (Ignore the black cloth on the background. These were shot after we finished & I saw no point in showing the set with & without it.)
2S. With the main bounce cardboard in place.
3S. From the back showing the 750wt Quartz "modeling" light & the two strobes.
4S. The black is a Velour backdrop fabric that soaks up the light. I added a red gell & this shot was at f/9 so I expected it to be underexposed about 1 stop more than what you see here.
5S. I meter off white paper. This was at f/10. Eye level white RGB readings in RSEP were 253, 251, 254 which was indicated in the cams LCD histogram by "blinkies" everywhere.
6S. This was at f/13. Eye level white RGB readings from the paper in RSEP were 239, 245, 241 - "blinkies" were only on the top-right corner of the paper. Close enough for government work!
Only USM 100, 0.6, 0 post processing was done on the resized shots of Kelly in the first examples. All shots were "On the paper meter" at 1/200 sec, f/13, ISO 100, & were taken in a 45 minute period. Total # of shots was about 70.
Thanks for looking, & remember, comments are expected! I'd like to keep this thread alive awhile so more people can see it.
