Abstract
In an earlier article (Québatte et al., 1986, ESO Messenger 46, p. 7), we have described a new method for the development of large photographic plates. This method, which we call grid processing, is based on the rapid motion of a metallic grid in the developer, very close to the emulsion surface. Experience has shown that this method is superior to the classical tray rocker, not only in terms of uniformity of development, but also in efficiency; the latter being of particular importance for long-exposure astronomical photographs. In the above-mentioned article, we showed some initial results which were mainly obtained by manual movement of the grid. We here report the continuation of the tests, now with the aid of the prototype of an automatic grid processing machine.
