The most noticeable difference between infrared pictures and normal photography, however, is the appearance of nature.

The green color of plants and leaves will now appear to be titanium white. While not particularly useful when taking photos in color, this effect will often create a much more visually-exciting black and white photo when shooting out in nature. Another consideration is focus. Because of its longer wavelength, it converges to a point that will differ from that of the visible light emanating from the same source. Any type of single-lens reflex camera relies on mirrors in order to function.

Mirrors reflect infrared light in a thermal sense only. This unfortunate fact makes these systems borderline useless when shooting infrared light; SLRs and DSLRs depend on the intrinsic properties of visible light in order to predict where the incoming rays will meet one another. Adjusting these tools so that they can be adapted for infrared photography basically means recalibrating them. Some lenses come printed with an infrared index mark, usually in the form of a red dot that's offset slightly from the mark that indicates correct focus ordinarily.

Abiding by the correct mark for the type of photography that you're partaking in will yield the appropriate results. In order to focus on an object 50 feet away when taking a normal photograph, you would roll the barrel until the foot mark is in alignment with this default focus index indicator.

When shooting infrared light, you would do the same, only using the red mark right next to it instead. If you shoot with a mirrorless camera, you're in luck.

With no mirrors separating the plane of photography from the subject, focus is determined directly at the sensor.

What is Infrared Photography? Ilija Melentijevic March 4, pm 4 Comments. What are the uses of IR Photography Infrared photography has a strong appeal for fine art photography. How is IR photography done? There are three general ways to do IR photography. Infrared film: This was the first method developed and for a long time this was the only way to shoot infrared. This required specialized film, the use of an infrared filter over the lens, and specialized developing. This can still be done today, but the film is hard to find.

Pros: Nostalgia, and learning to overcome challenges. Cons: Hard to find the film, hard to keep the film from fogging, exposure and focus bracketing required. Digital camera with an infrared lens filter : This is possible because modern digital sensors are luckily! These filters are not perfect, so by placing a IR filter on the lens and taking a long exposure, you can take infrared photos on some cameras. Pros: The cheapest way to try infrared. Cons: Long exposures require a tripod, motion blur, exposure and focus bracketing, less filter options.

But just wait until you do this looking through your camera! If you see the bulb light up, your camera can see infrared light. The whiter and brighter the light you see from the remote, the more sensitive your camera is to infrared. If the light is more purple or red your camera may not be a good candidate for shooting infrared photos.

The tripod will help you take a sharp shot, as your exposure times will be quite long. The filter will block most of the visible light from reaching your camera sensor, but will allow the beautiful infrared light to pass through. When I first started shooting infrared images, I used a Hoya R72 screw-on infrared filter. If you are using a slide in filter system, such as Cokin or Lee, they also make infrared filters to work with their holders. The R72 refers to the amount and type of infrared light that passes through to your sensor and I recommend using this to start.

It allows some visible light to pass to the sensor so it will allow you do to all sorts of creative post processing with your images. Infrared Image with creative post-processing. Because the infrared filter blocks out most of the visible light, your exposures will be quite long. Set up your camera on your tripod and make these adjustments:. Shooting in RAW will give you a bit more latitude for processing and adjusting.
