Modern photographers use in their work many technical devices — lenses, cameras, cameras and various accessories for them.
This is the hardware component of their work — but there is another, the technical part, which consists in processing taken pictures on the computer. It is impossible to do without this part, because many special programs have been invented that can almost everything, and in which every self -respecting modern photographer should understand itself.
Given the possibilities of modern programs, such a device as light filters, many seem useless to many. For many, this is yesterday — just like film cameras. And although partly such an opinion is true, nevertheless, in some cases, it is impossible to do without a light filter — now its purpose is slightly different, and is to create a picture that you want to get it in the future to process it. In other words — a platform for processing.
Relevant and not relevant in our time, light filters
In the technique and optics, a light filter is a device that overflowering part of electromagnetic radiation. Now many of its varieties are replaced by computer programs-for example, instead of a filter that changes color temperature, it is quite real (and cheaper) use the RAW format. Another, which is not relevant in our time is a “filter of effects”, which creates stars and rays — now Photoshop copes with this task perfectly.
There are devices that are relevant now — for example, an ultraviolet filter, the task of which is to prevent the penetration of the sun rays. He has another task — to protect the lens from damage.
The filter designed to eliminate glare and reflection on shiny surfaces is also used quite often — it is called «polarization», or simply «polar». For example, when photographing water, he removes various glare and reflections from its surface — from this the color becomes more saturated. It is also widely used to eliminate reflections in windows or windows.
Of course, all this can be done using computer processing — but then you will have to spend a little more time.
The above, as well as many other varieties of light filters, you will find on our . In the section «Photo Assessies» — «Light filters».
