Black and white .. Distinctive artistic prints

Shading and central burning are two important processes in the printing stage, to obtain distinctive artistic impressions, which move the photographer from the normal execution stage to imparting a creative spirit to his work, and the matter is worth studying as long as it is within our reach without little effort and without accessories or equipment....

Distinguished artistic impressions, the possibility of exploiting them increases with the increase of experience, practice and patience.

vignetting

In short, it is blocking the light of the magnifier from a specific part or parts of the image in order to coordinate the details in it according to the basic nature of these parts. In a dark, low-contrast spot, we may see that a part of it would have been better not to be as dark as the print here. We have to shade this part alone by blocking the light from it, either by means of a special performance or by means of the palm ... and the palm is simply the most effective tool. It is widely used even among professionals. As for the other tools. At the forefront is a very fine and stable wire, which ends at one end of the image with a cylinder made of cardboard or plastic in black color - its size is no more than a medium-sized coin, because this tool is often used to shade small parts in the image, and the shading process is done - whether in the whole or the other tool - In a consecutive manner, so that it is placed under the light for a moment, then withdrawn and returned for several times according to the required degree of contrast. It is not permissible to place it in a fixed manner, i.e. blocking the light once, because the contrast will be exaggerated here. As for determining a specific period, it is always up to experiments and experience, and there is no way to specify a fixed time. Warning It is simple here that the shading includes parts that we do not mean by this process. To avoid this, we must pay attention to whether the tool or

The part used in the palm is slightly smaller than the part intended for shading, while keeping it close to the magnifying lens to the maximum possible extent.

Central burn

It is the opposite of the previous process. Quite simply, the central burning of a particular part may mean a reduction of other parts, and vice versa. This process is usually done with names, a distinctive type of printing that used to make the sky - a part of the image - tend to be dark, by exposing this part with more light after finishing The normal darkening process for the image as a whole, dotted with the other part that is not intended to be burned by palm or other light-isolating tool for a certain period, so that the central burning will include the sky or clouds to tend to black, and with more experience we can work accurately to obtain a gradation in shades from the darkest at the top of the print to the lightest At the bottom of it, as for the small sites that need central burning, and these sites may be in the middle of the picture... Here, a piece of cardboard can be used with a perforated hole in the middle that corresponds to the part intended for burning. Through experiments, and there is nothing wrong with destroying some prints to finally get the desired results. It remains to be mentioned that we can perform two operations of shading and central burning on one print, so during the normal exposure we shade a ship, for example, in an image that includes the sea, the sun and space, and then we return to
Burning the comprehensive part of the sun or clouds in space, as required by the impression that we want to leave on the image, and so you get a distinctive print with a unique impression. After obtaining the required experience, we can return to our previous negatives to print them again so that you get amazing results compared to the previous editions of these negatives Before getting to know shading and central burning, we finally come to the importance of printing paper in this field. The first thing that should be realized is that dealing with paper with low grades is very difficult, so that the slightest error will appear clear in the print... So dealing with moderate grades of paper is best to get good results -
