If you use an IR filter, the exposure time is relatively long, so you will always need a tripod in this situation. We also recommend using cable release if swinging occurs.
FAQs of IR Filters
Hotspot
Hotspot is a relatively common problem of infrared rays. Due to the internal reflection of light inside the lens. Ordinary lenses have a coated barrel to absorb light, but these coatings do not always work with infrared and cause these issues.
Resolution:
1. Hot spots are often removed by changing apertures.
28. Hot spots are most frequently occurring at the same type of shooting angle that causes lens flare. In this case, the hot spot is usually avoided by shooting away from the bright light source.
Exposure:
With converted cameras, the exposure meter still works based on visible light. This may result in insufficient exposure or overexposure, as a scenes visible light and infrared light are not the same.
