Certified Professional Photographer (CPP) Practice Exam

What is the main disadvantage of photosensitive triggers when used in a group of photographers?

1. Interference from ambient light

2. Fast battery drainage due to repeated firing

3. Limited range

4. Slow response time

The correct answer is: Fast battery drainage due to repeated firing

The main disadvantage of photosensitive triggers in a group of photographers primarily relates to interference from ambient light. Photosensitive triggers rely on detecting light changes to activate the camera or flash. In a situation with multiple photographers, various sources of ambient light can trigger these devices unintentionally, leading to false firings or miscommunication between devices. This can be particularly problematic when taking pictures simultaneously in bright settings or during an event with fluctuating lighting conditions. While battery drain can occur with repeated use, it is not the most critical issue compared to the immediate operational challenges posed by ambient light interference. Other options like limited range and slow response time may have their challenges but do not encompass the broader issue of misfiring due to the proximity of multiple light sources typical in a group setting.
