When it comes to headshots I like to accommodate as much possible. I offer indoor with professional lighting and backdrops. I bring with me up to 3 Photogenic lightboxes, and both of my Canon Speedlight flashes. With these headshots, I didn't use any of these, not even my flash. Sometimes the flash can be very distracting and some people are much more sensitive to light than others.  Carmen had beautiful natural lighting shining in the many windows of her home. She also had white walls, tile and ceilings allowing the light to bounce.  I bumped up my ISO a bit and only used the lighting in her home. She had beautiful furniture to pose on. I hope she has much success as a realtor and loves her new business cards.
