 ART (CGI) 322: Evolving Techniques in Digital Photography.

4 hours (2, lecture; 2, lab), 3 credits. Computational algorithms and software to use multiple aspects of an image. Examples include panning in space and stitching the image together and exposure bracketing to manipulate dynamic range. PREREQ: ART (CGI) 321.



Location and Time: Fine Arts 047; Th 9:30 AM -1:00 PM+ field trips
Instructor: Robert Schneider

Grading Policy:
Field Trips: After an initial introduction to some techniques of computational photography we will alternate weeks with field trips and in class digital image manipulation and printing. We propose either The Hudson Yards area or the Hi Line area.

Resources and Idealized Course Outline  
Intro -August 31-- Topics- In all of these there will be significant lab time to learn appropriate software manipulations
  • Panoramic photography---Talked about and had students do some sample photography. Assignment to do more outside class
    • many apps on cell phones to make large picture
    • basically take many overlapping shots-- show trapeze shots and finished pictures

Second Class 9/7:

  • Student presentation of work for critique- manipulations in Lightroom and Photoshop explained as needed
    • HW for next time: continue with pans but you should do a pan with at least 16 images. You should try to use a tripod and take some pans early in the morning, near sunset when you may get a glow and as night is very near.
Third Class 9/14--  The field trip is this Thur  the 28th to look at Hudson Yards, The High Line and The Meat Market of NYC (weather permitting). We will meet at 9:30 AM in front of B&H photo at the entrance on 9th avenue between 33 and 34th street.
  • review of student pans
    • problems (or opportunities) to watch for
      • projection distortions
      • alignment
      • motion and ghosting
      • change of lighting
      • dynamic range

      • consistency in shots (or not)
      • focus-f stop- focus of camera
      • motion blur- shutter speed
      • white balance (gray card)
      • iso -- sensitivity of camera
      • focal length

      • parallax
      • blending (even if aligned and light pretty even there are always some variations)
      • projection
      • point of view
      • aspect ration not consistent
      • large files
      • display-- gets big


  •   HDR Imaging, Camera Raw and Tone Mapping
    • Go over creating hdr in Lightroom, Photoshop, Photomatix; use trapeze shot to demo. Note that modern cameras make hdr often unnecessary but demo use in cellphones.
    • Students take cellphones (or cameras) around Lehman  to practice taking hdr. Start using tripods and cable release. Use at least 7 shots
      • Try to get a scene that has high dynamic variations of light intensity-- dont work directly with sun
      • Don't use app on phone. Get 7 ev difference to see what you need to capture high dynamic range scene
        • Come back to class and put together-  display results- critique

  • What to do with pans

  • Go over creating, and modifying panoramas in Lightroom, Photoshop, AutoPano Giga
  • What to do with HDR

May have several labs and photographic outings before go on with succeeding topics

  Panoramas:
  • panoramas with hdr
    • hdr is a natural for panoramas as lighting can change drastically in a large sweep

  Focus Stacking

    Printing and Display
Assignments 11/16 (MidTerm Mini projects): You should practice at Lehman during class time where I can help

  • Make a modern picture of an object  by an opening with light streaming in similar to Renaissance portrait  paintings( you may need hdr/focalstacking).
    • A person will be hard unless you can do it quickly by an auto feature of your camera. If the person is not directly in front of the brighter background you may be able to deghost. It might work if the person is pretending to be in an mri.
  • Do a focal stacking of some ordinary household object in interesting light.
    • ex
    • there are sinks, presses etc throughout the art department
  • Make a pan of Pipes in subbasement of Lehman or of tubes just outside the hallway.
    • do the pan in hdr
    • you may substitute another scene in building
