Special techniques
Additional pieces for unusual effects

The additional pieces placed on the lens also increase the possibilities of displaying the subject. Many devices have been invented for scientific use, but few of them represent a real importance for classical photography. Putting something on the lens is not enough to give the image a greater aesthetic value: the best and most successful pictures are those taken simply and without any tricks.

However, some of these devices can help you overcome some problems: The polarizing filter reduces or eliminates unwanted reflections. The distorted glass lens compresses the image in a strange way, sometimes emphasizing and exaggerating a feature that was not apparent in the image (height allows or width of the building). A prismatic glass lens allows you to explode the image by repeating one subject several times on its surface. Compound lenses display the entire subject several times in images that overlap each other and slightly deviate from the other.

The right-angle device that shoots at angles, is placed on the lens and allows people to be photographed without being noticed.

Some special effects help to give a certain atmosphere to the image: the prism lens sometimes brings a poetic atmosphere to the landscape, this is a trick often used by advertising photographers. The starry glass lens used for night photography gives a radiant image from every illuminated point in the scene: car lights, candles, light trails, etc. There are different models that give different effects. We can also talk about lenses that adjust focal distances (not clarified) and all the rest of the tricks that change the geometry or the natural clarity of the image: placing a glass plate coated with petroleum jelly or another substance in front of the lens, shooting through a piece of colored or uncolored cellophane, etc. Effects like these do not necessarily produce a good image but they can help to give a little importance to a trivial subject.

- Glass lens for stargazing

It is placed on the lens like any filter, turning the bright points in perspective into stars and planets. The result is better if the light sources are points.

- Compressing the image with an anamorphic glass lens The anamorphic glass lens is used in cinema for widescreen formats such as CinemaScope: it has the advantage of compressing the image in one direction only without modifying the other direction. In these three images I wanted to show how the image changes shape by compression or expansion.

- Using a polarizing filter:
Light reflected from non-metallic surfaces can be reduced or eliminated by using a polarizing filter. The advantage of this filter is that it passes the oscillating light rays in one direction in the judiciary and stops the other rays. This effect is easily observed when examining reflected light through a polarizing filter that rotates around itself. The filter is not effective for all shiny surfaces. It reduces or eliminates reflections on a painted painting or on a car window but has no effect on metal surfaces. It is very useful for photographing oil paintings, shop windows, painted furniture or architectural subjects with large reflective areas. The image on the left was taken without a filter: it is surrounded by annoying reflections. The image on the right was taken with a polarizing filter which does not show this defect.

- Multiple images with revolutionary glass lenses
These three images show the effects of prismatic glass lenses. Depending on the model and its orientation, the image shows several perfectly symmetrical subjects on a horizontal, vertical or oblique axis, distributed regularly or irregularly.
