Dealing with Low Light Problems

Author: Brian Rhodes, Published on May 09, 2012

Getting high quality images in low light is a common challenge. With the problem being so widespread, we were curious to understand how integrators normally address the issue. In our latest integrator survey, we asked "How do you know if a camera location will have problems in low light? What do you do?". In this note, we dissect and analyze those answers, grouping them into 6 major themes of integrator practice.
