I know that in the "real" world (ie, not the photography world!) you all will not need to start thinking about the Holidays until after Halloween. However, this is the busiest time for many photographers, and the labs that serve them.
In order to have your order guaranteed by Christmas, your session MUST be completed by the 17th of November, with orders filed by the 30th of November. I have just a handful of sessions left within that timeframe! So if you've been dragging your feet thinking about sessions to give as gifts, drag no more!
