From Negative To Positive We Print The Photos
The printing step is simultaneously the most exciting (with the image that is formed before our eyes) but also the most delicate, especially if you are beginners.
The first thing to do is, as for the development of the film, prepare the three solutions that we will use for printing photographs from negative http://www.akusewa.com/sewa-led-screen-jakarta. As for the camera roll, there are three solutions to use: development, arrest and attachment.
Compared to the development phase of the film, we have fewer ties with the temperature: 20 ° are as usual reference but variations in positive or negative developments will affect only the time of development of the picture itself, without compromising the content. As for the solutions, remember to make enough to have at least one finger of solution in the tank because the card must be completely covered.
The developing solution is diluted 1 + 10 between the water and the chemical reagent (eg. The NEUTOL NE or WA). This means that for 1 liter of water should be using 100 cc of a chemical reagent.
To stop solution you can use the common acetic acid in a ratio lower than the developing solution. 1 + 2 (1 liter of water and 20 cc of acetic acid) are a good compromise.
The fixing solution is more or less in the ratio of 1 + 7 dilution (1 liter of water, 70 cc of reagent) and you can use a product like Agefix (based on sodium hyposulphite). In any case, this being the most important, always adhere to the manufacturer. A fastening prepared bad could deteriorate to the photograph in a very long time. And to avoid problems of “aging” of the early pictures remember to use as much as possible fresh solutions, one for each camera obscura. In any case, on the packaging, it is always reported the maximum number of printing papers that can be processed.
Once prepared the three solutions, we move into the scene through the magnifier. Place your negative in the negative leads. Make sure that the emulsion side is facing down.
After checking carefully the negative in the light of the lamp magnifier and making sure that no dust or external objects, insert it into the slot of the enlarger.
Place the printing paper under the enlarger and cover it with a card that will serve as a “test for composition.” Of course you could proceed using the red filter of the enlarger, but this will reduce the brightness by creating some problems in focus.
