I came across the site for "Inside City Team". They are a ministry team that travels through various cities in and out of America to serve the poor and homeless.
This particular blog post was about how one member of the team incorporated photography in missions work. He once believed that he would compromise his call to missions by going to college to major in photography. After a while, he realized that photography can be used for the missions field.
Photography in missions has been something that I have considered doing short term. I actually became a lot more interested in photography after participating in a short term trip to Guatemala the summer before my senior year of high school. The children in Guatemala were really fascinated with the little camera that I had and insisted that I took pictures of them and asked if they could take pictures too. Despite our language barrier, I was able to connect with them by the use of photography and was able to use it as a ministry tool.
