Feature

●Suitable for DSLR/SLR cameras with a 58mm filter thread
●Application: nature, scenic, often used in crime detection, medical photography, detection of the distribution of vegetation, etc.
●Material: high quality optical glass. Works well with digital cameras, especially mirrorless cameras or DSLRS without IR blocking filter in front of the sensor. (Please check the user manual of your camera)
●Infrared film is also sensitive to ultraviolet rays and the shorter wavelengths of the visible spectrum, so it is necessary to filter out all but the infrared rays
●The manufacturers warranty does not apply. Please check Amazons return policy, which usually offers free returns within 30 days of receipt.

Description

In which suitable light source should I use the infrared filters?

680nm for indoor use and weak shade.

720nm for indoor and low light use.

760nm for cloudy outdoor areas at nightfall and indoor brightness.

850nm for indoor and dimly cloudy outdoor light.

950nm for outdoor and strong light, like summer time.

Note:

Please set a custom white balance of your camera. The way you set different cameras may vary, please check your manual.

The exposure time is relatively long when using IR filters, a tripod is absolutely necessary in this situation. We also recommend that you use a cable release in case of shock.

Common Issues of IR Filters

Hotspots

Hotspots are a relatively common problem with infrared. This is due to the internal reflection of the light inside a lens. Normal lenses have coated barrels to absorb light, but these coatings do not always work in infrared, causing these problems.

Solution:

1. Hotspots can often be eliminated by changing the aperture.

2. Hotspots occur most commonly at the same shooting angles that cause lens reflections. In this case, hotspots can usually be avoided by shooting away from bright light sources.

Exposure:

For converted cameras, the light meters still work based on visible light. This can occasionally cause under-exposure or overexposure as the visible and infrared light of a scene may not be the same.
