I do most of my fashion shots at home and due to lack of space I'm forced to do them in a narrow white corridor.
I only have a single light for now and I'm trying to get pictures where there are no shadows from head to toes on me. Any suggestions?
Most effective way of getting no shadows with a single light would be be with ring light around your lens. I'm assuming it's a speedlight, in which case you could add a DIY Ring Flash Kit to your light for this purpose.
Or, you could turn the part of corridor behind your back into a huge ring flash by pointing flash on-axis in opposite direction of the subject. That takes noticeably more flash power though.
My personal preference would be to have some slight shadow by a large light source to make the subject more spatial. To get a large light source, the flash has to be bounced from into wall where you'd normally place a softbox. Use a snoot, barn-door, black card etc. to make sure no direct flash hits the subject. A zoomable flash head lets you control size of the "softbox".
It would have been really great if you could specify the type of lighting you were using. Would have simplified the job a little more. But assuming that your using a flash gun with a umbrella you could just shoot with it with the stand a little to the camera left or right depending on the situation. You could also the and use a reflector but it would be kinda useless in case of a full body shot. With a flash gun and umbrella it is possible to get a full body shot. I've tried it and it works. A little shadow is unavoidable but sometimes when used well really adds to the shot. Also keep your subject from being close to the background. That way the shadows on the BG can be reduces it for eliminated. Also with this you will achieve a slightly blurry BG.
