Ratings and reviews

Love the app makes taking the perfect picture so much easier and definitely less expensive then buying a dedicated light meter. The other day I was think that if there was a way to add camera profiles that would make this so much better than it already is. We all know that different cameras react differently. Or maybe lens profiles. At the end of the day great program as is. Thank you for developing it and your other great products also.

Quick, simple to use, effective, clean implementation.. Thanks. As a former application developer and consultant of 20 years I can say these folks have done a great job on this little tool. As a camera nut I find it indispensable.. Great instructions and support information as well ...

just what I needed. rookie level user interface. absolutely beginner friendly.
