Light Kodak

Expose the dried gels on an X-ray film that is sensitive to blue light (Kodak X-Omat AR or equivalent) at -80°C (with intensifying screens, if required) until the desired signals appear on film development As required to visualize signals... 

Eastman Kodak white label 2,4-dinitrochlorobenzene, which had a light tan color, was used without further purification. 

Protocol updated from Krolak et al. (49) and Dashek and Mills (50). Controls (a) Germinate pollen without [14C]-pro and process as before, (b) Construct a radioautographic sandwich with collodion lacking pollen, (c) Expose a slide coated with Kodak NTB-2 Nuclear Track Emulsion to light and develop emulsion with D-19. (Sample autoradiographs are presented in Fig. 3.)...

Dissolve Lissamine rhodamine B sulfonyl chloride (Kodak, Molecular Probes) in DMF at a concentration of 1—2 mg/ml. Protect from light and use immediately. 

Table 3.1 Filters that should be used for accurate color reproduction. The filter depends on the light source as well as the type of film used. The filter numbers are references to Kodak Wratten filters. The first digit designates the color and the letter the density of the filter (data from Hedgecoe (2004)).

Ordinary printing paper can be handled in a relatively high intensity of dark-brown or red-brown light, corresponding to Kodak OC or OA filters (OC is more commonly used... 

Almost any panchromatic film made today can be pushed one stop with little or no discernible loss in quality. For example, Kodak Tri-X can easily be pushed to El 800 and Ilford Delta 3200 (which is closer to El 1200 than it is to ISO 3200) can easily be pushed one stop to El 2400. Try adding 25% to the normal development time for Tri-X, and 25% to 40% with other films for a one stop push. With testing and experience, you should be able to capture almost any event on film, regardless of how little ambient light is present. (See Yuette at the Coffee House on page 53 )...
