It Isn’t Magic, It’s Energy: night photography in space by Marcos Alberca
Light in photography is essential, but we don’t always have control over it. If we are working outside of a studio and using natural light as our light source, the exterior is much more difficult to control, although if we know how to adapt to it the results can be great.
Another important factor when taking photos is whether we want to take our photos during the day or at night. Light appears differently on the objects on which it is reflected, not only at different times of a day, but also in the different seasons of the year.
In summer, the sun at its highest point is at a great height, and the arc that it travels during the summer days is very high, meaning the shadows that are produced are small, the light falls vertically on the landscapes and objects and generates fewer shadows and our photographs are more clipped, that is, the elements that make them up have fewer contrasts between them.
In winter, however, having a smaller arc, the shadows are more horizontal and elongated, which makes the landscapes more interesting and produces more attractive plays of light.
Night photography is perhaps one of the most spectacular photographic disciplines: photos takes from after sunset until before dawn. Due to the paucity of the light we have, we need to expose for a longer time, that is, long exposure.
In this discipline, we must understand the 3 elements that affect the exposure of our photos: the aperture of the diaphragm (which limits the ray of light that penetrates the camera), exposure time (the shutter is a curtain that opens at the moment you take the shot) and ISO (ISO is nothing more than the sensitivity of the sensor when capturing light) and the relationship between the 3 values.
If you understand and control these three elements you can have the best configuration to take night photos, now go and practice!
Now you know: it Isn’t Magic, It's Energy!
