Description
Note:
This filter is only suitable for infrared-modified cameras. The effects shown cannot be achieved with a normal, unmodified camera.
The camera must be converted with one of the following filters: 280 nm (full spectrum), 550 nm, 630 nm or InfraBlue.
A 700 nm filter allows light in the range from 700 to 1,200 nm to pass through. When you hold it in your hands, you practically have a black disk in front of your eyes. The 700 nm filter can be regarded as a "true" infrared filter because it no longer allows any significant parts of the visible light to pass through. It can be used to produce both color IR and black and white infrared images. It is the most commonly used filter and is always recommended for undecided "beginners" in infrared photography.
For black and white infrared photography, the filter provides a very high contrast image with almost white foliage and dark sky. It is true that stronger IR filters provide a little more intense image results, but at the expense of sensitivity. If the focus is more on color IR photography, the 630 nm or InfraBlue filter is a good alternative.
