Tri-X 400 at ISO3200 in Rodinal - Semi-Stand Development Test
Semi-Stand test with 500ml of Rodinal (Adonal) diluted 1:100 at 70F for 2 hours. 1 minute of initial agitation and 3 gentle swirls of the tank every 30 minutes: Kodak TriX 400 (135) shot at ISO 3200: '61 Zorki-4: Jupiter-12 35mm f/2.8: Parameters = 1/250th at f/4
There looks to be some exposure unevenness in the taekwondo shots. At first I thought this was caused by the development process but based on the lack of the same pattern on the shots taken under normal light and slower shutter speeds I believe this may be attributable to the fluorescent lighting in the building. Incandescent lights produce a constant intensity light since the element glows from resistance induced heating. Gas discharge lights produce a cyclic pattern of light intensity that, due the frequency, will affect pictures and video taken at higher shutter speeds. The pattern is consistent with light frequency anomalies you would expect to see for horizontal travel curtains and the slow curtain travel speeds of these old cameras. The gap between the curtains during travel at higher shutter speeds with slow curtain travel times (in this case 1/250th) is narrow and would, I believe, produce the effects seen here.
