5 Aerial Photography 5 Black & White Recording Films Assortment FilmsProcessing Aviphot Pan 80 Aviphot Pan 200Colenta Aerial Processors Aviphot Pan 400 SVersamat and other continuous tone processors

6 Aerial Photography 6 Black & White Recording Films Applications uPhotogrammetry (mapping, cadaster ) u tendency to use colour images is obvious u emerging competition of digital airborne uInventory Studies (NIR sensitivity) u satellite imagery /Digital airborne u false colour IR films (no Agfa product)

7 Aerial Photography 7 Film for recon applications uReconnaissance (Oblique and vertical ) u airborne- SAR is latest battlefield technology u UAV with video for close recon. u Film still valid because: u high definition imagery / large footprint u universality and compatibility u sturdy and operational (can be scanned too !)

8 Aerial Photography 8 Black & White Recording Films Use Aviphot Pan 80 uHigh altitude (with FMC at low, medium to high altitudes) uUsed as pan-chromatic B/W duplication film (from colour negs.) uMilitary and civilian applications uAviphot Pan 200 uLow, medium or high altitude uMilitary and civilian applications

9 Aerial Photography 9 Black and White recording films Use Aviphot Pan 400S uLow altitude or high contrast objects uallows for uncritical film exposure. uoptimised for film scanning umilitary and civilian applications uPan 400s PE0 major business in security camera

10 Aerial Photography 10 Black & White Recording Films Product Profile & Requirements uGood detail rendering: u Extended sensitivity into the near infrared (less scattering, higher reflection) u High resolution uMaximum speed  minimum granularity uAppropriate processing and sensitometry uDimensional stability uEasy scanning uGood physical properties

11 Aerial Photography 11 Black & White Recording Films Characteristics Aviphot Pan 80 PE1 uPopular film in mapping community uExcellent contrast range – variable in processing u Very high resolution u Extended near infra-red sensitivity

12 Aerial Photography 12 Black & White Recording Films Applications uAviphot Pan 80 PE1 and Pan 80 PE0 u High resolution panchromatic duplication film u Military reconnaissance up to 30.000 ft (with AD74) u Cartography: replaces Pan 200 u very fine grain u best scanning results u larger blow ups u more scales in one photo flight.

13 Aerial Photography 13 Black & White Recording Films Characteristics Aviphot Pan 200 PE1 and Pan 200 PE0 uMain military / mapping film (average light conditions) uNIR extension used in forestry applications uLarge contrast variation during processing (at 30 °C during 20 to 70 s) low gammahigh gamma In G 740.801.80 In Kodak 885 developer0.851.70

18 Aerial Photography 18 The blue component of white light is heavily affected by the front and back scatter. The near infrared spectral reflection is hardly affected. The near infrared reflected image shows the best resolution. The back scatter of the blue light illuminates the shadows Black & White Recording Films Imaging Techniques

19 Aerial Photography 19 650 nm filter 515 nm filter

20 Aerial Photography 20 Black & White Recording Films Imaging Techniques Two different imaging techniques Yellow filter Agfa system: Agfa system: Blue + green + red + near infrared Other system: Other system: Diminished blue + green + red Blue light Green light Red light Near infrared light Film planeObject

21 Aerial Photography 21 Instead of having no image details in the black shadows, the image details are revealed by the front scatter of the blue light Resulting picture — Agfa system with blue light information Black & White Recording Films Imaging Techniques

22 Aerial Photography 22 Black & White Recording Films Imaging Techniques Advantages of the Agfa system uNo loss of “blue” shadow information uNo loss of “blue” contribution to overall speed uBetter haze penetration (sensitized into the near infrared) uBetter image differentiation in density levels on film

23 Aerial Photography 23 Pan 400s uReplaces Pan 200s u Target applications ? u Survey market for wide latitude applications u Survey market for low light / long shadow u Military market for reconnaissance

24 Aerial Photography 24 Black & White Duplicating Materials uFilms uPhotographic papers

28 Aerial Photography 28 OPEN SKIES

29 Aerial Photography 29 Black & White Papers Assortment u Rapitone P1-P2 fixed grade paper u Rapitone M2 multicontrast paper uPaper prints = diminishing sales for Agfa u market color oriented u Military: big volume, bottom price market u market fade-out depends on market situation in 2004

30 Aerial Photography 30 Black & White Processing & Chemicals uQuality Goals for density range uProcessing chemicals

31 Aerial Photography 31 Black & White Processing Goals Recording films Standard processing + film/chemistry (G74c) combination of same manufacturer: best image trade-off uUnder-processing: u better grain and sharpness, lower speed and gradation u enough light ? Fixing ? Washing ? uOver-processing: u larger grain and less sharpness, speed and contrast gain

32 Aerial Photography 32 Black & White Processing Goals Duplicating films Can be processed in G 74 and rapid access developers (e.g. G 101) uFor projection only: Look for an average gradient between 1.2 and 1.5 uFor use on a scanner: u Low densities generate low digital image noise u Look for a density difference of max 0.6 (also recording films) u Look for lowest possible fog level (Dmin)

33 Aerial Photography 33 Black & White Processing Goals Photographic Paper Can be processed in G 74 and rapid access developers (e.g. G 101) Little impact of chemistry on the sensitometry Development agent in the paper coating uSelect grade to match density difference in the recording film

34 Aerial Photography 34 Black & White Processing Processing chemicals Developers uG 74 c (recording film, duplicating film and paper) uV-dev (duplicating film and paper) uAD 74 (booster of G74c)Fixers u G 333 c/ V-fix + aditan (10ml/liter), replenishment rate 500 ml/m² Development conditions uTypical for the used chemicals u G 74 c: 30 °C, replenishment rate 250 - 300 ml/m² u V-dev: 35 °C, replenishment rate 250 ml/ m²

35 Aerial Photography 35 Black and White Processing Processing chemicals AD74 in combination with new developer G 74 c and starter G 74 s uAllows fast processing (40 seconds sensitometry at 20 seconds) u40 seconds sensitometry is steeper and faster uCan be airshipped without restrictions Fixer G 333 c / V-fix + Aditan hardener uFast fixer (minimum recommended fixing time = 20 seconds) uCan be airshipped without restrictions
