PROCEDURES FOR CAPTURING TREE IMAGES WITH KODAK DC120

I.  BARK IMAGES

     A.  Single point auto-focus, flash ENABLED, camera position with long axis
     parallel with long axis of trunk.

     B.  Select a side of the trunk that is in complete shade, zoom to fill frame with
     entire trunk, shoot.

     C.  If image appears too dark (usually caused by inclusion of brighter background
     when      trunks don't fill entire frame) increase the expose by selecting +0.5, +1.0,
     +1.5, or +2.0 manual exposure.

II.  FIELD SHOTS OF TWIGS, LEAVES, FLOWERS, FRUITS

     A.  Single point auto-focus, flash DISABLED, camera position with long axis
     parallel with longest dimension of specimen.

     B.  Position specimen on black velvet background in complete shade, zoom to fill
     95% of frame with entire specimen, shoot.

     C.  If parts of  image appears too light (usually caused by inclusion of brighter
     objects, like under sides of leaves or flowers against black background) decrease
     the expose by selecting -0.5, -1.0, -1.5,  or -2.0 manual exposure.

III.  LAB SHOTS OF TWIGS, FLOWERS, FRUITS, DETAILS

     A.  Macro-focus, flash DISABLED, camera position from specimen measured with
     a ruler and nearest focal length manually selected.  Usually camera is controlled
     via Twain Acquire routine in Photoenhancer running on desktop computer.

     B.  Position specimen on black velvet background, disconnect parallel port cable
     from camera, use preview function to adjust specimen and camera height such
     that specimen fills 95% of frame, reconnect parallel port cable,  shoot using
     Twain Acquire control panel, if image is acceptable transfer from Twain Acquire
     to Photoenhancer.

     C.  It may be desirable to bracket focal distance + and - around measured focal
     distance.  Do this by disconnecting parallel port cable from camera, select focal
     distance, reconnect parallel cable to camera.  If parts of  image appears too light
     (usually caused by inclusion of brighter objects, like under sides of leaves or
     flowers against black background) decrease the expose by selecting -0.5, -1.0,
      -1.5,  or -2.0 manual exposure.

IV.  TRANSFERRING AND ERASING IMAGES FROM THE DC120 TO COMPUTER

     A.  Image transfer is most efficient if the Kodak Image Transfer Routine is used,
     since     this will  transfer all or selected images automatically.  Transfer images in
     TIF format if you intend to edit these using PhotoFinish.  The initial size of these
     images are huge! (3.4 MEGS).  In order to work with multiple images in
     PhotoFinish, use PhotoFinish to Proportionately Resize the original images to 640
     X 480 and replace the original images.

     B.  Images are most efficiently erased from Camera and Card Memory by
     disconnecting parallel cable from camera and using camera on-line functions to
     erase the card memory.  This takes a few seconds as compared to several
     minutes if the Twain Acquire routine is used to erase the card.

V.  POWER PROCEDURES FOR THE DC120 

     A.  Whenever laboratory operations are being done (image capture, transfer, or
     erasing) the AC Adapter should be connected to the camera to conserve battery
     life.  The AC Adapter DOES NOT charge batteries in the camera.  The AC
     Adapter should NOT be left connected to the camera when the camera is not in
     use, since this will generate unusual amounts of heat in the batteries, which can
     result in battery meltdown and damage to the camera.

     B.  NiCad rechargeable batteries should be completely drained of power before
     removing them from the camera for recharging to avoid the "memory factor"
     associated with this type of rechargeable batteries.  Place the drained batteries in
     the recharger immediately after removal from the camera.  Recharging requires 5
     hours.
