Three aerial films were tested using standard aerial photo laboratory processing procedures for three different chemistries. Relationships were established with respect to average gradient, speed, base plus fog, graininess and resolution for low, medium and high contrast targets. The films compared were Kodak Double-X type 2405, Kodak Plus-X type 2402 and Kodak Panatomic-X 2412. The processing was done in a Kodak Versamat processor using Type A, 885 and Versaflo chemistry. The results indicated that processing in 885 chemistry enhanced film speed. The versatility of Double-X in terms of speed and contrast range was demonstrated, however the resolution of Panatomic-X greatly exceeded that of either of the other two films and shows promise for small scale mapping photography.

Dancefilm muddles the paradigms that would position film as an order of production controlling all cinematic motion (including camera movement, film speed, editing etc.), and dance as motion, liberated and encompassing any-movement-whatever. David Hinton and Siobhan Davies’ experimental film, <em>All This Can Happen</em> (2013), draws text, image, and edit together via a poetics that is of the order of the choreographic. In a dialogue that echoes the collaborative spirit of the film, Erin Brannigan and Cleo Mees explore the corporeal and choreographic sensibilites at work in <em>All This Can Happen</em>, recognizing dynamics of breath and weight in various aspects of the film’s composition, including the movements of the bodies on screen, the qualities of the edit, and the text of Robert Walser’s original novella (on which the film is based). In exploring these corporeal-cinematic qualities, the authors work across and soften the dance-film binary described above.

The potential benefits of Kodak's Tabular Grain Emulsion Films (brand name: T-MAX) has resulted in our lab considering a switch from Kodak TRI-X 4×5 sheet film to Kodak T-MAX 4x5 sheet film for use in SEM photography. The current regime is TRI-X sheet film developed in D-19 diluted 1:2. Processing is at 20°C in large (4l) tanks with N2 burst agitation. The procedure used for this study was T-MAX and TRI-X sheet film processed in T-MAX RS developer; using the same large tank, and No burst system, but at temperatures ranging from 20° -24°C. The potential benefits are: 1) Improved image quality; tabular grain emulsions are purported to have improved sharpness, a finer grain at a given film speed, and better tonal separation than previous emulsions. 2) Ease of use; T-MAX RS is a highly miscible liquid concentrate which can be used at 20°-24°C. The primary temperature recommendation is 24°C; this would reduce the need for chilled water at our facility.The initial comparison was made using Kodak TRI-X and Kodak T-MAX 400 sheet film. Exposures were made using a JEOL T330A equipped with a high resolution photo CRT and waveform monitor (WFM). Brightness settings were determined using the WFM in the procedure described by Holm. Four sets of eight exposures each were made for both T-MAX 400 and TRI-X. A set consisted of one sheet of film exposed at each of the zones represented by the lines of the WFM. One set of each type of film was processed at each of the four specified temperatures,(20°, 21° 22°,24°, using T-MAX RS developer, at the time recommended by Kodak. Negative density was determined using a Zeiss Axiophot equipped with a MPM 20 Photometer. The percent value of transmitted light (%T) was converted to diffuse density (D) using the formula D=Log 1/T. The calculated diffuse density was plotted against the brightness line position on the WFM. Granularity was examined by visual comparison using 12x enlargements from T-MAX and TRI-X negatives of similar density.
