Happy Friday everyone!  The weather here is certainly lacking but at least it's not -20 or snowing, so overcast and rain it is!  Overcast day's can actually make for some great outdoor portrait sessions!  Don't ever assume you have to cancel a session just because it is not hot & sunny out.  Granted, we don't want our customers to be cold with lips turning blue, but a cooler day with lots of clouds or completely overcast also makes for some great photos!  Check out the link below to a fantastic article with 101 photography tips, great tips for everyone.  Not just a reminder to actual photographers but always a good read for people before they go to their own sessions or just some basics before you pull out your point & shoot or cell phone at the next bday party or hike in the woods!
