Photography typically uses lenses to project light on to film, and then on to paper, in order to render an objective representation of a scene or object. A photogram, on the other hand, is a scale negative record of a shadow. It is unique and unpredictable. Photographs tell sweeping, barefaced lies; photograms tell the truth, but only a thin slice of it. Is this why photograms, and other cameraless photographic techniques, currently proliferate in contemporary art?
The ocean of images that surges and swells around us is mainly photographic; we are awash with manipulated half-truths and shameless fictions. Smartphones allow you to edit and enhance images seconds after you shoot them.
We are all of us eloquent in the language of photography, from the shallow depth of field of the expensive SLR lens and the all-over focus of the large-format Hasselblad to the vignetted corners of yellowing Polaroid snaps. Falls has also used coloured light to make luminograms — close cousins of the photogram, records not of shadows but of light itself.
Some people contend that photograms came into existence over a century before photographs.biopostnepomi.tk
Lighting by hand #4: into the shadows - By
The German physicist Johann Heinrich Schulze noted the darkening effect that sunlight had on a jar of silver nitrate solution in However, the size and shape of the shadow can change. These changes are caused by the position of the light source. When we are outside on a sunny day, we can see how our shadows change throughout the day. When the Sun is low on the horizon, the shadows are long. When the Sun is high in the sky, the shadows are much shorter. We can create the same effects indoors by changing the position of a torch as it shines on an object.
Although the shadow effects are the same, the reasons for the moving light source are very different. When we use a torch to make long and short shadows indoors, it is the light source that moves. When the Sun makes long and short shadows outdoors, it is the Earth, not the light source Sun , that moves.
From our vantage point on Earth, it appears that the Sun moves across the sky during the day. We see the Sun appear to rise in the east and set in the west. Actually, the Earth is spinning rotating on its axis so it is our view of the Sun in the sky that changes during each hour cycle of light and dark. We see the sunrise when our location on Earth spins towards the light of the Sun. As the Earth continues to spin, we see the Sun higher in the sky.
As the Earth spins away from the light, we see the sunset.

When New Zealand is in darkness during the night, the opposite side of the world is in sunlight. During the summer, our location is tilted towards the Sun, so our midday shadows are very short. During the winter, our location is tilted away from the Sun, so our midday shadows are longer.
Sure, I thought, great idea. But they added that they would rather these kids be set apart in different classrooms. This is a real challenge. In fact, teachers in these settings are undertrained, underpaid and ill-equipped to deal with students with disabilities. Sometimes their own knowledge, attitudes and beliefs towards disability are also part of the problem.
We have a problem of stigma, a problem of access, a problem of capacity. So how do we deal with it? This is what people call a wicked problem.
Out of the Light, Into the Shadows
And the only solution to wicked problems are courageous solutions, not one-off stints. That means a whole-of-system approach. We have to create behavior change across society, and we have to engage with all the actors across the human-development-education-emergency-response field to create integrated solutions. Some solutions are presented in their guidance on Children Living with Disabilities in Humanitarian Crisis. In order to do this, Education Cannot Wait is investing in programs that mainstream gender equality and equity including disability.
The Secret to Painting Realistic Shadows in Sunlight
We collectively work to make inclusive quality education a reality for disabled children. They cannot be an after-thought. Inclusive education is a government policy in Uganda.

As one colleague remarked deliberate efforts for inclusive education come with a cost but this should not deter us. In the refugee settlements in Uganda it starts with understanding and creating a culture of inclusion.
