• Samsung A707: first cellphone, photos from 2007-2009
• LG VU and VU Plus: photos primarily from 2009-2013
• HTC First: photos from 2013-2016, during this time I started using cellphone cameras more often
• Samsung S6: photos from 2016-2017, heavy phone camera use during this time. use of multiple apps means some photos may be out of order
