When I discovered infrared photography, I knew almost nothing about it and searched all over the internet before deciding to us Kolari Vision as my source for information. The web site is very informative and they quickly answered all my questions. I decided to put my trust in them to help me choose the right camera for conversion, including the type of filter, and I was not disappointed! And I got it back within just a few days. I have recommended Kolari Vision to several friends and family who have shown an interest in IR photography. When I decide to upgrade to a DSLR, I will be contacting Kolari vision for advice and conversion services. Meanwhile I’m going to enjoy using my Canon G9!
