Presentation

Our December speaker was Adam Woodworth. Adam’s presentation took us on a winter journey through Maine and New Hampshire, from the coast to the mountains, day and night. He shared stories behind his winter shots, and discussed techniques for keeping us and our cameras functioning in temperatures down to -40F.

Adam Woodworth is a landscape photographer, award winning filmmaker, and software engineer.  He is originally from Maine and now resides in New Hampshire.  He has had a love of photography for most of his life, and one of his main focuses is landscape astrophotography.  His earliest memory of gazing up in awe at the night sky was as a child in a canoe on a lake in Maine, fishing at night.  The intensity of the star filled sky in such a peaceful spot was a powerful experience, and now he enjoys sharing that experience through his photography.  You can learn more about his shooting and editing techniques through his tutorials on his website: www.adamwoodworth.com.

Assignment

Our assignment for the December meeting was to create images that demonstrate maximum depth of field using the techniques we learned at the November meeting:

  • Increase depth of field by using a smaller aperture (F8 vs F2.8, for example). But beware of an effect called diffraction which will cause your image to appear blurry at very small apertures (F32, for example).  See the diffraction calculator at Cambridge in Colour for more information.
  • Use the concept of hyper focal distance to calculate where to place your focal point to achieve maximum depth of field. See the hyper focal distance calculator at Cambridge in Colour for more information.
  • Use the technique of focus stacking to combine multiple shots of the same scene taken with different focal points into a single image that is sharply focused throughout. Helicon Focus software helps with this technique and is available for a free 30-day trial.
  • Experiment with a tilt-shift lens to increase depth of field by tilting the focal plane. Tom Lawrence will bring his tilt-shift lenses to the November outing for folks who want to experiment.
