Infrared photography is a unique and creative form of photography that produces stunning and surreal images. Infrared light, which is outside of the visible spectrum, can reveal hidden details in your images and add a dreamy and otherworldly quality to your photos. To capture infrared light, you need a camera and lens that are specifically designed for this type of photography, or a specialized filter that allows infrared light to reach the camera's sensor.


If you're using a Canon camera with an EF lens mount and want to try infrared photography, one option is to use the Kolari 720nm Infrared Drop-In Filter for the EF to RF Lens Adapter. This filter is designed to be used with an EF to RF lens adapter, which allows you to use your EF lenses with a Canon camera that has an RF mount, such as the Canon EOS R5 or R6.

One of the benefits of using the Kolari 720nm Infrared Drop-In Filter is that it produces very little noise in your images. This is because the 720nm wavelength is near the edge of the infrared spectrum, and it produces less noise compared to filters that allow for even more infrared light to pass through. Additionally, the 720nm wavelength is close enough to visible light that it still provides good contrast and color information in your images.

Using the Kolari 720nm Infrared Drop-In Filter is simple and straightforward. The filter is designed to be a drop-in filter, which means that it fits directly into the lens adapter and does not require any additional attachments. To use the filter, simply remove the original filter from the lens adapter and replace it with the Kolari 720nm Infrared Drop-In Filter.


The only thing left to do is swapping the blue and red channels in photoshop. You can achieve this with either an action or manually. If you want to do it manually or use some other software, find the option called channel mixer. In the red channel, reduce the red to 0 and set blue to 100. Do the same for the blue channel reducing blue to 0 and setting the red to 100.
