Hello All,
Here are my Notes for the SLO Bytes Photography Group that took place on 03/13/2022
TOPIC: Controlling Depth of Field
Ralph Sutter illustrated how changing shutter speed and aperture control the depth of field.
Sutter shared images of flowers. The first image was shot with the aperture at maximum opening and the shutter speed adjusted for proper exposure. The second image in each pair stopped the lens down to f11 and increased the exposure speed for more light. In some images, he used a zoom lens at 140mm for shallowest depth of field.
Kaye Raul emphasized the advantage of using focus peaking for maximum sharpness in her shots of Sea Canyon and Avila. Kaye alternated between color and black and white to show the advantages of each format.
John Waller experimented with both a new Canon full frame camera and a new lens while lamenting the learning curve when switching. He hopes to use the pair for capturing sharp images in very low light.
Connie Sutter concentrated on a single Poinsettia flower, varying the shutter speed and aperture and noting the effects
Alan Raul showed images of powder-coated steel structures located in Waller Park commissioned by the Museum of Contemporary Art of Santa Barbara.
He also showed images of the wooden walkway at the end of Grand Ave. and some shots around Pismo Beach.
Alan spoke about his new Sony A7 iv mirrorless camera purchased in January.
Using his previous purchased Sony (Zeiss optical design) lenses he noticed "substantial and noticeable" improvement in his shots.
The auto-focus is "extremely fast and accurate."
