I have done a number of portraits of children and babies and been happy with the compositions but not the lighting. They have either been underexposed or blown out at one side. I have spent ages adjusting the background in photoshop to create hi key effect as the white backdrop is still quite visible.

I have an idea that you have to increase the output in the flash heads behind the subject by one stop more than the flash heads/soft box in front of subject. Is that correct?

Would any of you guys be so kind as to give me some standard tips on where to position the lights in relation to the White backdrop, subjects and camera. What settings to have the rear flash heads set at in relation to the front set - if that makes any sense?

My studio kit comprises of 3x Portaflash heads, 2x silver and 2x translucent brollies, and 1x soft box.:thinking:
 
People seem to be skirting around answering this one Gilly, and I'm not really surprised - photography isn't an exact science that lends itself to an easy answer to your question, there are far too many variables invoved in your particular situation.

The fact that you're having difficulty achievng the effect you want with Photoshop assistance really speaks volumes - I've yet to see a high key effect produced by processing which is remotely convincing, although I appreciate that you are in the first instance trying to get your high key effect with lighting.

High key lighting is far from easy so it's not surprising you're having problems as both the light set up and exposure need to be spot on. Do persevere and don't be disheartened. My approach would be to set up one light at a time - get the first one right, then add another, checking the set up each time until you're getting the overall effect you're after.

Check your results from each light - assuming you're using digital, and don't be in a rush.. the results are well worth the patience when they come. :)
 
Thanks for responding CT. I know - you are quite right it is not an exact science. I think I will do as you say and set it up one light at a time and practice that way, rather than all the lights up and jiggling around for the next hour trying to reposition them.

When I can work out how to post a pic on a thread, I will upload one from my last shoot and invite comments then. Thanks again. Gillian :thinking:
