Intermittent agitation, method

Develop only one sheet of film at a time or use a sheet film developing tray (see Resources Photographers Formulary). Use the intermittent agitation method I describe in Chapter 4 Agitation and do not lift the negative from the developer until it is time to move it to a water... 

When radiating and receiving surfaces are not in parallel, as in rotary-ldln devices, and the sohds burden bed may be only intermittently exposed and/or agitated, the calculation and procedures become veiy complex, with photometric methods of optics requiring consideration. The following equation for heat transfer, which allows for convective effects, is commonly used by designers of high-temperature furnaces ... 

There are four methods of agitation Intermittent, minimal, continuous, and stand development which will be discussed in its own section below. In order to obtain negatives with the highest degree of edge sharpness and contrast of fine detail, intermittent, minimal, or stand development must be used. Continuous agitation should be avoided.
