hi guys.

need a little input once again

i did a photoshoot at the weekend fopr a friend of mine, i was asked to shoot some models in shirts. the space i had to work in was relativelty limited

I had a two white pieces of material draped from cieling to floor. To light them i had three flashes . Two on the background and one with a softbox on the subject

i seemed to get patches of light on the background and i even tried to over expose it in camera. i have included some pre shoot shots. and i will also include a diagram of the set up i was using.

thanks again

Mathew

the flashes were fired as follows:

Softbox = wireless trigger
Background flashes = through slave triggers

Iso 200
apeture F10
shutter 1/125
 
were you shooting your background flashes bare, or into brollies? etc..
 
both background flashes were shot bare and shot at full power
 
If you don't have a flashmeter then the following is a good way of getting it about right.

1) Take pictures of the background with the camera set at the aperture that you want. Increase flash power until the histogram shows all white. Maybe add 1/2 stop just to be sure. Make the background as flat as possible so that folds don't cause shadows.

2) Put the model in front and take a test shot with no front flash. You should get a very underexposed model lit only by the light bouncing around and getting to the front of the model. If too much light is getting to the front of the model you may need to start moving the mode further away from the background and start painting things black !

3) Assuming that all this is OK, you can start to add front flash from the softbox until you are happy with the setup.

This is how I did it and managed to get (background not quite white but not far off), a bit too much front flash though.:

sometimes I used to have issues when trying to shoot onto cloth with bare flash. because the cloth is not even, and the bare flash is not very diffused, it causes shadows on the backdrop and does not light it evenly. I avoid this by shooting them into reflective brollies onto my background. hope this may help


Would be interested to see some shots of the problem :)

Totally agree with the above, We have spent a bit of time in the studio doing high key studies on my hnd course and I really recommend that you invest in a light meter. It makes life so easy, first decide what exposure you want to photograph your subject at and then meter your background light +1.5-2 stops more.

Take a look at Gary's site www.photolearn.co.uk for some tips.
 
I did something similar at the weekend for a friend (2 daughters)
in the end i put one of my strobes behind the backdrop bare tube, kept playing until it blew the white out, then used another fitted with an octobox in front, worked out ok
 
how much would a decent but relatively cheap light meter set me back??
