What is the contact press?
Contact printing is a photographic print that is produced by exposing a sensitized piece of material, such as the development of paper to light while in direct contact with the negative. It was a standard technique used for the development of photographs until the magnification has developed and is still used today. There are two primary modern uses for contact prints: fine arts and leaves. Many novice photographers learn in their career very soon on prints of contact to create evidence of their photos.
To create a contact print, the photographer set the light surface face up under a light source such as magnification. Furthermore, the negative is placed directly on the upper part of the sensitized material and the light is on to detect the paper. After a specified period of time, the light turns off and the paper evolves. Many people use this technique to create evidence or contact sheet a lot of negatives, so onimít the small versions of the photos they looked at and allow them to decideUT, which pictures evolve.
It is clear that the contact sheet is limited by the size of the negative. Photographers with large formats of negatives that may vary. Artists like to create contact prints of large negative formats due to the resulting richness of detail, which can simply be incredible. During the magnification process, the detail of the image can be distorted or muddy and the contact printing perfectly retains all the details. During the enlargement process, the negatives also work large formats; For example, Ansel Adams worked with large format cameras to produce his significant work.
This principle also applies to digital photography. Digital photographers have probably noticed that the more information they store in the photo, the more they can play with it. Digital camera with a small megapixel capacity will produce grained large prints with covered details while more MEGapixels are equal to more details and the result of higher print quality.
Ieing the contact press requires some work. If you work with enlargement as a light source, the lens will be modified and it will be necessary to change the height of the enlarged head. The photographer must also make a test belt to determine which exposure level would be best for the contact printing. Contrast filters and other tools can also be used to change the resulting finished printing quality. Photographers who still experiment with large format cameras could want to try it.
