红外胶片对紫外线和可见光谱的较短波长也很敏感，因此除了红外线外，还需要过滤掉红外线。

使用红外线滤光片时，曝光时间相当长，在这种情况下，必须使用三脚架。我们还建议您在发生抖动时使用电缆释放。

热点是红外线相对常见的问题。这是由于镜头内部的光的内部反射。普通镜片具有涂层桶吸收光线，但这些涂层并不总是在红外线上工作，造成这些问题。

通常可以通过改变孔径来消除热点。

热点最常发生在引起镜头闪光的相同类型的拍摄角度。在这种情况下，通常可以通过远离光源避开热点。

Works well with digital cameras, especially mirrorless cameras or DSLRS with no IR blocking filter in front of the sensor. (Please check your camera's owners manual)

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 exposure time is relatively long when using IR filters, a tripod is necessarily needed at this situation.We also suggest you to use a cable release in case shake happens.

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

Hotspots can often be eliminated by changing the aperture.

Hotspots occur most often in the same type of shooting angles that cause lens flare. In this case, hotspots can usually be avoided by shooting away from bright sources of light.
