Fine Art Process: Willis for placing within his power a process by which he is able to produce work comparable, on artistic grounds, with any other black and white process.. . . No artist could rest content to practise photography alone as an art, so long as such inartistic printing processes as the pre-platinotype processes were in vogue. If the photo-etching process and the platinotype process were to become lost arts, we, for our part, would never take another photograph.
The steel is to be made by the basic oxygen, open hearth or electric furnace process. The steel is to be killed and made with fine art process-grain deoxidation practice.
A second process which predominates with gamma-ray energies in the region between several hundred thousand and a few million electron volts is the Compton effect. In this process the gamma photon is deflected by an electron to which it loses part of its energy. At energies above 1.02 Mev the pair production process in which an electron and a positron are created can occur. This third process becomes predominant at higher energies.
