As an alternative to full-length sessions, I occasionally I offer "mini-sessions" - these are shorter in length than regular sessions, are offered at a discounted flat rate, and typically include a limited number of digital files. Mini sessions aren't intended to replace full-length sessions, but rather to offer clients an opportunity for a more specifically themed set of photos. For this reason, I usually schedule mini sessions around a particular season, holiday, or theme - i.e., "back to school," Halloween, Mother's Day, Valentine's Day, etc. - and I frequently hold them on-site at a location that compliments the theme (apple orchard, pumpkin patch, etc.).
Mini sessions are booked on a first-come, first-served basis and usually have very limited availability. The best way to ensure that you are notified of upcoming mini sessions (as well as other seasonal promotions) is to like/follow the WTI Facebook page.
