I first started using Saving Face software in 2008, and I can’t go back! When I was working on  'Inseparable Coil;  ( http://www.imdb.com/title/tt1408378/ )

I had to contend with identical twin lead actors, who sometimes had to look different, and

sometimes like each other which meant I had be to right on the ball with continuity!  Saving Face made my life so much easier by cross-referencing all my actors, scenes and shooting days.  The information I needed was always so easy to find.  I could upload continuity photos and store detailed information on makeup and effects, which was then accessible in easy to read breakdown reports. 
Since then Doug and Maureen have improved the program even further, and I now use it to do all my initial script breakdowns in pre-production, going back in to add the details of individual actors once established.  I have used the software on several productions since then and keep finding more ways in which it simplifies my job. I love not having to search through folders for bits of paper, and uploading photos from my digital SLR camera and then to Saving Face means I have instant reference to them – no more confusion about which photo belongs to which date or scene! 
 
Saving Face is a time saver too allowing you to copy and paste scene information or character details from one page to the next.  This is especially valuable where there are a lot of performers in a particular scene, or when you have a character

whose look does not change much over several scenes.   
These days, an essential part of my kit is my laptop and my SavingFace software.
