BATH-ROCKING CHAIR

BATH-CHAIRThe most popular formats of images of photographers ranging from 9X12 to 18X24 cm. This is for several reasons. First, prints of this size can be stored in albums, creating a photographic family “chronicle”. Second, the use of large formats entail additional financial costs related to the acquisition of the relevant ditch paper and large quantities of chemicals. And third, it is often the decisive factor printing large images requires a large area of the laboratory, thereby eliminating the possibility of work in the favorite by the majority of photographers place — the bathroom.
But it happens that especially well the resulting negatives like “ask yourself” on a large format. It can be made a portrait of a loved one or a beautiful landscape that may well decorate the interior of any apartment. In short, the impression from which much increase, if it will “consider” you, not you it. What to do in this case? To run to the store for shopping?..
To visit the store, of course, have — you will need a paper size. But without big ditch and additional quantities of reagents can be dispensed with, if to make one tray with a curved bottom. This design will replace all three tanks for processing solutions and will take the minimum place in a laboratory of any size.
 
Processing exposure as follows. A sheet of paper is slightly bent and placed in the tub. Then poured the developer. It should be enough to cover about a third of the imprint (when specified on drawing size corresponding to the format of 30X40 cm, the solution should be about 1 liter). In order for the manifestation proceeded uniformly over the whole area of the photograph, the capacity should be shaken by “pumping” the solution from one wall to another. It is better to use one of the recipes for slow developers.
 
Removal of the cell solution is the drain hose. After developing, the print is washed under running water, and the stage of fixation. It is similar manifestation, but unlike developer fixer should be fast — this will reduce the processing time. The final operation is the final rinsing.
 
Cuvette for processing photographic paper, large format.
Cuvette for processing photo paper large format:
1 — bottom, 2 — side panel (2 PCs), 3 — nozzle (tube Ø 20X1 mm, length 40…60 mm), 4 — discharge hose (rubber, PVC), 5 — clamping ring (A — position the drain hose at the time of development and fixing of prints).
Make a tray with a curved bottom can from a sheet of polystyrene, sheet metal or thin aluminum. The connection of the walls in these cases are performed using, respectively, gluing, soldering and welding. As the clamp on the drain hose using a metal or plastic ring, a suitable internal Diameter. If necessary, the size of the device can be changed in any direction.
 
Another addition, based on their own experience. It is hardly necessary to deal with the mechanization of the process of the swing of the cell, as it is unknown how often it will be used, and “manual” mode with a visual inspection allows time to monitor and, if necessary, in time to influence the degree of manifestation of the individual parts pictures.
