Photography is one my hobbies here in Lethbridge, it helps keep my creative juices flowing, and lets me get out on my own a little bit (as an introvert, I thoroughly enjoy this!).
After a few positive comments, I've decided to start offering some of my favorite/best photos for sale through a print-on-demand service. If you're looking for some Southern Alberta canvas, acrylic, metal or poster prints - check out my online store!
I've even got some new abstract digital art!
Update: I've recently sold a Milky Way print on canvas - you can get your own copy of my Milky Way print here!
