What lighting equipment do you use?

When you keep your distances and use the zoom, you always end up with shots that are straight and square, you never get odd angles.

I like to shoot the angles and side views. That way, the girl can take a more natural pose, moves less and more at her own ease, and thus, you can get better body language.

The downside is that you risk creating shadows because you shoot from nearer, and you have to move more. That produces less frames per per unit time, increases the risks of tripping a lamp stand, etc.

You can't have your cake and eat it too. Shooting the angles is my personal preference. Mind you, I won't bust a gut by shooting straight, square and center...

Distortion should be eliminated with a good quality lens.

Shooting in wide angle can increase the proportion of certain body parts, which could be interesting IMO.

As for guys who kindly offer to help you, the rule is:
if they offer you, refuse them. Hire only the reluctant ones.
