Description
Предлагаемый способ ис1-слючает необходимость комплектации универсального фотоувеличител двум сменными конденсорами.The proposed method is1-including the need to complete a universal camera enlarger with two interchangeable condensers.
Способы использовани в универсальном фотоувеличителе одного конденсора дл печати при смене объекти зов известны.Methods of using a single condenser for printing when changing objects are known in the universal photographic enlarger.
Способ отличаетс тем, что прн за.мене объектива / 110 мм на объектив / 50 мм (напри.мер, в универсальном фотоуве.1ичителе «Нева 2 м) при переходе от формата 60x90 мм к формату 24X36 мм конденсор переворачиваетс }ia 180, i; результате чего он устанавливаетс в фотоувеличителе на 60 мм выше прежнего положени ; на эту величину поднимаетс н с прикрепленным к ней матовым стеклом.The method is characterized in that the lens replacement / 110 mm per lens / 50 mm (for example, in the universal camera Neva 2 m) when changing from a format 60x90 mm to a format 24X36 mm, the condenser turns over} ia 180, i ; as a result, it is installed in the photographic enlarger 60 mm above the previous position; this value rises with matte attached to it.
Таким образом, рассто ние от матового стекла до конденсора и отThus, the distance from the ground glass to the condenser and from
конденсора до входного зрачка объектива сохран етс посто нным и изображение матового стекла остаетс в плоскости входного зрачка объектива.The condenser to the entrance pupil of the lens is kept constant and the image of the ground glass remains in the plane of the entrance pupil of the lens.
На чертеже показан фотоувелнчнтель с раз.тичными положени ми конденеора п лампы, согласно описываемому способу.The drawing shows a photographic helper with the discrete positions of the condenser and the lamp according to the described method.
Предмет изобретени Subject invention
Сиособ использовани в универсальном фотоувеличителе одного конденсора нри смене объективов, о тл и ч а 1О HI и i с тем, что, в цел х использовани при печати с разноформатных негативов одного и того же конденсора, конденсор соответственно смене объективов ( на / --- 50 и наоборот) переворачивают на 180.The way of using a single condenser in a universal photo enlarger when changing lenses, about 1HI and i with the fact that, for use in printing from multi-format negatives of the same condenser, the condenser is corresponding to changing lenses (on / --- 50 and vice versa) turn on 180.
