September/October Photo Tour on Focus Stacking (or Other Things), Yosemite Area

See my in-depth coverage of focus stacking in MSI and/or my Depth of Field Challenges: Bypass the Limits with Focus Stacking, Near or Far, Macro or Landscape.

For late September and early October I’m offering 1 or 2 day outings concentrating on focus stacking (or other things), including how to best shoot for a “stack” and how to process the images after shooting. We’ll spend part of the day shooting, and part of the day processing. A laptop is not essential as I will have mine along, but bringing your own is the best way to learn. I recommend 2 days because that allows a day for feedback and learning, and then a 2nd day for trying more.

Dates are flexible, but in the range of Sept 27 - Oct 7, when I’ll be in the high country of Yosemite and/or the ancient Bristlecone Pine area of the White Mountains. Group size kept to 1 or 2 people—this is a one on one. Cost is $800 per day, or $600 per day per person for a 2 person arrangement. More info on photo tours. Contact Lloyd.

The composition benefits from having everything sharp near to far. At f/9, there are two unpalatable options: either the tree is badly blurred with focus in the distance, or the tree is sharp with blurred background: the range is too great for to achieve sharpness by stopping down. Stopping down to f/13 would only make a less blurred image, not a sharp one. In the full-res stacked image at actual pixels, a diamond-shaped road sign with a dark symbol inside it can be seen on the road far below along Tuolumne Meadows. View at 50% of actual pixels and see the actual pixels crops.
