33 Washington Wing Photo Methodology Critical Elements Airborne photography is an Aircrew Activity A clear understanding of the customer s requirements must be obtained prior to launch The Mission is to position the airborne photographer so that the best possible photos can be taken Every member of the aircrew is responsible for the success of the mission Training as an airborne photography aircrew is essential

34 Washington Wing Photo Methodology (cont.) Problems to avoid Customers usually don t want photos of cows in flooded fields Ensure that GPS data is available in the EXIF header Customers don t want a dozen photos if one or two will suffice. Don t overload the customer with too much data, especially useless or unnecessary data Time is a critical factor get the photos delivered to the customer quickly Meet the mission parameters

35 Imaging Flight Patterns m The 4-Square imaging pattern is the standard imaging pattern for most missions, as it is the simplest and most stable pattern that results in very good images m The Bird s Eye (Overview) pattern is used to show an overview of a target or when images need to show detail between structures (e.g., between buildings or between trees) m The Circling pattern is more difficult to master, particularly if the Airborne Photographer is shooting out the right-side window. This pattern is good for taking quick shots of multiple targets, and can be used if a quick survey of widespread damage is needed by staff to determine resource needs and plan more detailed sorties m The 45 Angle to Target pattern is used when the customer specifically asks for these types of images

36 Imaging Flight Patterns m Both the Mission Pilot and the photographer must be familiar with how any particular imaging pattern will be approached and flown; that s why planning is so essential to a successful mission m Once you decide on which type of pattern to use, fill in all the data you need (e.g., lat/long of all entry and turning points) to fly the pattern using the GPS and/or VOR m How the Mission Pilot maneuvers the aircraft into the proper position for each shot is very important. m The approach to the imaging pattern should be stable, and the photographer must be given enough time to analyze current conditions and set up for the photo or video imaging run

37 Imaging Flight Patterns If you are performing damage assessment and didn t know the extent or type of damage to expect when you left on the sortie, the ID Pass will be followed by an assessment survey The circling flight pattern is a good pattern to use Also, you may want to sketch the damage to help you decide what images you need and what imaging flight patterns to use You may need a combination of flight patterns and/or need to make several runs to capture all the damage

38 Imaging Flight Patterns m Aerial Imaging flight patterns are always flown at 1000' AGL or higher, and never at speeds below V x m Every imaging pattern starts with an ID Pass that allows you to verify the target and note its coordinates Examine the target and its surroundings, and decide how to frame your photos in the upcoming passes Also ensure you are at the right altitude to get the desired video or photo

39 Circling Imaging Flight Pattern

40 4-Square Imaging Flight Pattern

41 Bird s s Eye Imaging Flight Pattern 1 Factory Circle target to find the altitude that will permit horizontal framing and determine the best direction from which to take the imaging photo 2 Factory Shooting from right window at best altitude and direction Approximately 75 knots (not V x ), 10 flaps, 10 bank and full opposite rudder

42 Crew Communications m The first pass by the target is very important m This is the time to determine: You are at the correct altitude (angle) for best results You are looking in the right direction for best results You are at the correct distance from the target You are flying at the correct speed Whether or not you need to (and can) use the zoom to properly frame the photo m If any of these conditions aren t met, have the pilot turn around, correct the problem, and redo the first pass

43 Crew Communications m The Mission Pilot must always strive to put the photographer in the proper position for a shot m Small adjustments, not obvious to the pilot, must often be made to get the right angle or position Lifting the wing, moving the strut out of the frame or making minor course (heading) changes are the most common adjustments

44 Crew Communications m The pilot must be aware these maneuvers may be necessary, and the photographer must know how to direct the pilot Keep the directions clear and simple: Lift your wing or Move the strut forward or Left 10 tells the pilot all he needs to know The pilot also needs positive feedback, especially if you are shooting out of the right-side windows. Use simple words such as Good, good to let the pilot know they re on the right track and speed Finally, tell the pilot when the adjustments are no longer required by saying something like OK, I have the shots

45 Crew Communications m The photographer must decide whether the pictures satisfy all mission requirements m Don t be afraid to admit that you didn t get a particular shot, and ask the Mission Pilot to reposition for another try. Never hesitate to make another pass or to reposition the aircraft to ensure a good photo, and don t let any other crewmember rush you. m Remember, you should take as many photos as you think you need to fulfill mission requirements There s plenty of room on your storage media, and the extra time you spend doing this on-scene is much less expensive and timeconsuming than having another sortie go back to the target because you didn t get the right images

46 Factors Affecting Success m Vibration comes from the airplane, its engine and air turbulence m To reduce the effects of vibration, hold your camera properly and don't rest any part of the camera or your body against the airframe In particular, keep your arms and elbows from coming in contact with the window sill or armrest. Ideally, the only part of the airframe that will be in contact with your body is the seat cushion

47 Factors Affecting Success m It s best to wait for the best visibility instead of shooting through haze or other obscuring conditions Even on clear days visibility is rarely unlimited, so you always have to adjust to actual conditions over the target m Haze and fog are the most likely limits to visibility you have to deal with m Ways to deal with haze and fog: When you fly over the target during the ID pass (discussed below), see if there is a difference between looking straight down at the target and looking at a slant angle. With haze, lower angles to the target are often better. With fog, the reverse may be true

48 Factors Affecting Success m Focus. Even though you re flying at 90 knots your distance from the ground (altitude) stays roughly the same m When using Autofocus (AF), the camera shutter will not activate until the shot is in focus; this will cause a short pause; proper procedure is to press the shutter down halfway, wait for a beep tone and then press all shutter all the way down. m Focus each shot perfectly, even if you change the zoom setting m If you re using Manual focus, set the lens at the Infinity stop unless you're using a lens longer than 200 mm or are at less than 1,000' AGL Most AF lenses can focus past infinity and have to be focused with the AF system

49 Prepare the Aircraft m Clean the aircraft windows before you leave, and make sure you have cleaning supplies on board m If you will be shooting out the right front window of the aircraft, remove the window holding screw m Enter any waypoints into the GPS before takeoff m Set up and test the Audio Panel and Intercom m Check the imaging equipment Note: A shot of the aircraft N number with the camera or camcorder provides a good starting image for the sortie, particularly if there are images on your media card or tape from a previous sortie m Arrange your equipment for easy access, but ensure lightweight objects such as charts and logs are not lying loose where they can be blown about the cabin when you open a window to take pictures

50 The ID Pass m Known Location The Mission Pilot or Mission Observer should enter the coordinates into the GPS as a User Waypoint, and display this waypoint on the MFD (G-1000) When you pass over the target, verify you have the right target m Unknown Location The Mission Pilot or Mission Observer should enter a grid or search box of coordinates into the GPS as User Waypoints, and display the waypoints on the MFD (G-1000) When you pass a target, log the coordinates to match to photos and as a back up to the GP-1.

51 The ID Pass m If needed, perform a damage survey and plan the imaging pattern (s) necessary to fully document the damage May need to sketch the damage area as an aid to planning May need more than one run to fully capture the damage May need to take photos from different altitudes and angles Reassess your fuel status and plan a refueling stop if needed Update Mission Base on your new sortie time assumptions

52 Prepare to Enter the Pattern m Fly at least 1000' AGL during daylight and at least 2000' AGL at night, and no slower than V x m Ensure you re flying slowly enough to allow the Airborne Photographer to get several photos from each angle or side of the imaging pattern (usually kts)

53 Prepare to Enter the Pattern m Check that the camera is on; it may have automatically turned itself off Don t confuse this with the sleep mode where the camera turns off the LCD to conserve power; a quick tap of the shutter, info button or two taps of menu button will wake the camera m The third crewmember readies the Photo Log (CAPF 104b) and/or Recon Sketch Sheet m Secure loose items (e.g., charts) in the cabin and then open the window

54 Taking Photos m Steady the camera m As the aircraft closely approaches the point where you intend to shoot, begin framing the shot m When you near the shot point, you should prefocus on the target for faster camera response Focus on an object that is currently the same distance away as the target will be once you are lined up (i.e., in the same plane as the target) m Once the target moves into frame, press the shutter button the rest of the way down to take the picture

55 Taking Photos m Take several photos on each leg of the pattern m Keep the Photo Log keeper aware of what you are shooting It is easier on the log keeper if you tell them when you will be taking several photos per leg On each leg, tell the log keeper the following photos will be taken looking east or looking northeast or looking between the northern-most buildings, then call out shot 1, shot 2,.. This allows the log keeper to quickly and accurately log the photos

56 Using the Telephoto Lens m Let the zoom improve your position, either by bringing the target a little closer or backing off a bit m Zoom in until you get the frame you want or until the image begins to shake; if the image starts shaking, zoom out until the image becomes steady

73 Determine Success or Failure m You must check and make sure you have good photos and GPS data because you don t want to fly all the way back to mission base and then discover that you missed a shot, that your shots weren t framed properly or you don t have coordinates m Review photos in the camera before returning to base m Plan and re-shoot as necessary

74 After The Sortie m m m m m m Turn off the camera and the tracker Disconnect cables as required Replace the lens cover Make sure you have all your equipment before you leave the aircraft Clean the windows for the next sortie If no more imaging sorties will be flown in the aircraft, replace the aircraft window screw (and bushing or washer) if it was removed for your flight

75 After the Sortie (cont.) m Transfer your photos to a computer in mission base as soon as possible. Delete bad photos and superfluous photos m Ensure that the photo properties file contains GPS data m Upload photos to a designated Dropbox file, web site, or to the WMIRS sortie as directed by the AOBD m Some mission bases will just have you give them the media card. In this case, transfer images back to the SIM card and be sure to put one of your spare cards back in the camera, check that it is empty, and put the camera back in its bag.

76 Debrief m Check in with Debriefing Officer, Photo Analyst or AOBD: THE CREW REPORTS AS A TEAM At the mission briefing you would have received a timeframe for sortie deliverables. Remember that time is an important factor in most photo missions Deliver SIM card or report location of uploaded photos; deliver AMOD GPS Photo Tracker Tell how you did your job and what you saw Report whether all photos have GPS data; Photo Analyst may need to use alternative methods to geotag photos Complete CAPF 104, including written description of photo activity and survey results Charge both camera batteries and the AMOD GPS if necessary Account for all components and place in Pelican case

77 Post-Sortie Photo Processing The mission base Photo Analyst will need to perform a number of steps to complete the photo sorties 1.Create computer files to transfer sortie deliverables a. Title should be the name, date and other mission description b. Create computer subfolders 1) Raw photos 2) GPS track 3) Stamped photos 4) KMZ file 2.Transfer photos from camera, SIM card, Dropbox or other location to raw photos file 3.Transfer aircraft track from tracker, Dropbox or other location to GPS track folder

78 4. Using RoboGeo: Post-Sortie Photo Processing (cont.) a) Start RoboGeo b) Skip step #1 c) Step #2 import photos from raw photos computer folder d) Step #3 Import tracklog file from GPS track computer folder. Save project e) Step #4 Stamp the location data onto the photos. Save to the mission folder. Do not specify north arrows unless the crew can provide info for each photo. Wait approx. one minute for RoboGeo to complete f) Step #4 cont. - export to Google Earth create KMZ file, then close

79 Airborne Photography Training and Evaluation Beginning April 1 and through the end of April there will be funded training sorties for aircrew to practice aerial photo techniques. Each training sortie must meet the requirements of USAF/CAP training exercises, including an evaluation of aerial photographs and flight tracks. mclass attendees need to team up in two or three man crews and contact a designated FRO/Photo Mission Manager for a mission assignment. meach class attendee will be given a sortie to deliver mission deliverables as a photographer 1.
