The photos displayed here are the work of two professional photographers. Erisem and Tutholh were both early 4,1000 artists who cared deeply about non-default-spectrum photography. Erisem lived in Twin River City for most of their life and willed their collection of original prints to the museum. Tutholh was from just south of the northern ocean. Their work is more widely known as they are perhaps the most well-known non-default-spectrum photographer. Erisem and Tutholh actually collaborated during their lives, and their joint photography is located at the end of the hall.
This picture shows a view from Erisem's apartment window, looking out over the city. They have used a spectral mapping which compresses the visual spectrum towards the red end, allowing ultraviolet light to take the place of blue. The fact that higher-frequency light scatters more easily in the atmosphere lends the entire image a blue tint, even though the sun appears more green.
Notice how the reflections off of the windows are a bright, rich blue — a side-effect of the UV filters which are a common inclusion in window glass. These rich colors are typical of Erisem's photography.
This next picture shows the sun rising through the ocean. Ultraviolet light scatters efficiently off of water, concentrating it in the image near the rising sun. The other wavelengths of light are left to bleed into a larger portion of the sea, and to reflect off of the clouds, giving this photo the appearance of concentric rings of color.
In the far corner of the image, the "Watcher of the Harbor" is just visible in the dawn light.
These four photographs were part of a series which Erisem did on flowers. Each one shows a different flower — in clockwise order, a rose, a dahlia, a tulip, and a foxglove. Notice the patterns of ultraviolet shading which are not normally visible.
This picture shows the view from under a tree on a summer day. Notice how, although the landscape is brightly lit by ultraviolet light, the leaves do an effective job of filtering it out. The richer brown of the leaves stands in stark contrast to the pale blue of the surrounding area. The stems and veins of the leaves are highlighted by this choice of coloration.
Tutholh was more interested in long-wavelength photography. They frequently used a spectral mapping which — while not technically an inverse of Erisem's technique — has the effect of showing visible light as blue and infrared or radio light as red.
This picture is an image of a person camping in a snowy forest, trying to light a fire. Notice how the person's exposed face and hands glow a deep red that casts reflections on their surroundings. The dark blue of the snow and the trees makes this picture seem as though it was taken at night, but it was actually taken in the late afternoon, as you can see from examining the shadows. The fire, while it remains unlit, is much warmer than the surrounding materials. Tutholh titled the piece "Enkindling".
This photograph, which uses a slightly less extreme spectral map, is titled "The Fire Within". It shows a person smiling and extending a hand towards the viewer. Their eyes and mouth are much warmer than the rest of their skin, making them stand out brightly against the rest of the image and making it hard to discern their expression. They cast a glow on the back of a second person, who is wearing a head wrap and facing away from the camera.
This picture — "Squires of the realm" — shows two puppies playing in a sun-dappled courtyard. Notice both how their eyes and teeth stand out, but also how their heads and paws have a rich purple color. The movement of the sun also means that the heat in the stones of the courtyard is lagging behind the visible light, leading to the fading halos of red around each patch of light.
These three photographs were a collaboration between Erisem and Tutholh entitled "Differentiated sight". The first of the photographs depicts Erisem working in their darkroom. It was taken with one of Tutholh's cameras, and shows both the small, hot confines of the room, and the even blackness of the photos being developed.
The second photograph shows Tutholh lounging on the porch of Erisem's apartment, proudly showing off a book which appears completely blank due to the lack of ultraviolet pigmentation. Erisem is visible to the side of the image, peering in confusion at the book. Notice how they both appear older in this spectrum.
The last photograph shows the two of them smiling, arm in arm. Erisem's hands are folded, while Tutholh has their hand raised to wave at the camera. It uses a different spectral map from the other artworks displayed here, rendering visible light in green, ultraviolet in blue, and infrared in red. This choice renders their eyes and mouths brown, and their faces an over-exposed white. The landscape behind them shows both colorful blue foliage and insects, and the pervasive red heat of a hot day.
