DEVELOPING

After taking the photographs, we spent our 4^th workshop in developing them.

What we first had to do is to extract the film in a dark room, being careful, we open the roll and get the film, cut the ends, and charge it in a plastic spiral. After this, before turning on the light, we have to put the spiral in a tank, so light can’t get into the film. After, we can turn on the light.

Now, it’s time to keep the process with the chemical part. Three substances are needed: Revealer, stopper and fixer. First, we have to pour the revealer in the tank. We move it rhythmically around 7 minutes. Then, we take it away, and put the stopper around 1 minute, shaking it 10 seconds. The last step is the fixer, another 7 minutes approximately. After retiring it, we wash it with water and get the film. Now, the light doesn’t affect it. We wait the film to be dry, and continue with other step.

LABORATORY/CONTACT SHEET

To do the “positivism” process, there must be two zones, the wet one and the dry one. What we first have to do is getting a contact sheet of our photographs.



To do this, we have to put in contact the negatives with the sheet of photograph paper. This one is sensitive to usual light, but not orange one (only illumination). We cut the negatives, choose one to prove the exposition time and put it against the sheet, covered with a glass.

We estimate the time by covering part by part in the negative, so there are zones which are exposed more time than others. (We can do it each 2 seconds).

To reveal it, we submerge the paper in the revealer, stopper, fixer and final washed. It is approximately one minute, 10 seconds, other minute and 20 seconds, respectively.

We dry the paper, and then we do the same with all the negatives, to do our contact sheet, using the time of exposure we find right according to the negative we have done before.

Now, we can do the ENLARGEMENT

ENLARGEMENT

 

We choose the picture we like the most, and firstly, we have to choose the time of exposure. We put the red filter in the enlarger machine, and cut a piece of paper to put in the surface. We retire the red filter and expose it for 3 seconds. With a black paper, we cover some space of the paper and expose other 3 seconds. Then we do the same, covering less space each time. After do it in the whole paper, we reveal it as said before. Then, the part of the picture we think has the best exposure corresponds with the time we have to use for the big picture.

And we obtain something like this,
