Beyond the Photo Shoot

The obvious thing that photographers charge for is their time during the photo shoot. But beyond that, what other factors do photographers need to factor in to their pricing structure? 

- Equipment - professional photo equipment (camera, lenses, flashes, batteries, filters, studio lighting).
- Cost of props, particularly for newborn photo shoots. 
- Time spent editing (I usually spend 5+ hours editing a 1-2 hour photo shoot). Every photographer differs in how much time they spend editing, if at all. 
- Time spent cleaning studio, before & after a shoot. 
- Time spent washing wraps and blankets following a newborn shoot. 
- Time and money spent marketing. 
- Time spent answering emails and phone calls. 
- Water and electricity used for studio lighting, washing etc. 
- Time spent giving consideration to the styling of shoots. 

This is not a conclusive list, but may give an appreciation of all the many factors that are involved.
