Johann Van Der Walt is a Fujifilm X-Photographer from South Africa. He defines himself as an “amateur photographer who takes his hobby seriously” and he is very active in the field for sure.
In addition to being part of the Royal Photographic Society and the Photographic Society of South Africa, he is also an honorary member of the China Photographers Association and represents his country in the Global Photographic Union. He has participated in several exhibitions and has also won various prizes. Finally he regularly hosts landscape and safari workshops.
Johann uses Fujifilm cameras with infrared filters for his long exposure landscape work. In his latest guest post written for Fuji Love, he shows some images taken on a recent trip he made to the historical Montagu Pass in the Outeniqua Mountain.

He first gives a brief explanation about the area and shares some historical facts. Then he explains how he uses a modified Fuji X-E1 and X-T1 with a 720mm infrared filter, but not before mentioning what infrared photography is all about:
By adding an infrared filter in the light path we can prevent normal visible light to reach the sensor, and by keeping the sensor open long enough, we can record only the infrared light that passed through the infrared filter and through the hot mirror.
He explains that the infrared filter acts like a normal ND filter, which allows you to use a slow shutter speed and create movement in the scene. He also lists his favourite lenses because not every lens suits this technique well. Finally he explains how experimenting with white balance can generate interesting alternative colours, as well as why many photos can look better in black and white.
