July 2020 Meeting: Improve Your Skills

Just like every year in summer, we invite you to learn and Improve Your Skills in the Sierra Club Photo Section’s July 2020 meeting. This year we have Stephen Bay showing us how to make Cleaner Night & Astro Photos with Exposure Stacking and our president Alexander S. Kunz with an Introduction to Long Exposure Photography. Continue reading if you’re interested. This is an online meeting via Zoom and for members only. You can find the meeting date & time at the end of this invitation.

Cleaner Night & Astro Photos with Exposure Stacking

Night & astro photography always require making photos at high(er) sensor sensitivities (ISO). With the poor signal to noise ratio, more visible noise is introduced. Exposure stacking is a simple method to reduce the amount of noise in such photos. Stephen Bay will explain the concept & theory behind it, and show practical usage with the popular “Starry Landscape Stacker” software for Mac. The same techniques can also be used with the similar Windows software “Sequator“.

Introduction to Long Exposure Photography

Dragging the camera’s shutter is a popular technique to blur moving elements of a scene – most popular for water, it can also be used to blur cloud movement, and with really long exposures, create unique, unusual or minimalist renditions of popular subjects. Making very long exposures comes with some unique challenges – from a pitch-black viewfinder when using strong neutral density filters, to calculating the correct exposure times. In his talk, Alexander will show you how to easily tackle these challenges and make beautiful long exposure photos.

MemberShare

After the main presentation, we’ll take a short break before we continue with our MemberShare. Here’s a quick reminder of the guidelines and procedure:

  • Send up to five photos via Dropbox file request.
  • Please send only JPEG files, sRGB color space
  • Minimum resolution: 1920 pixels wide or 1080 pixels high (whichever comes first)
  • No maximum resolution but anything larger than 3000 x 2000 is unnecessary
  • Prepare to speak no more than 10-20 seconds on each photo
  • We’re a photo club – please share only your original photographs with us (no CGI, digital art, etc.)
  • Deadline for MemberShare submissions: Friday, July 17th 2020, 6pm
  • Nameplates: feel free to include a portrait format headshot with your photos

To submit your images, simply click this button:

SEND YOUR PHOTOS

If you need help or if there’s anything unclear about this procedure, the Dropbox help article on file requests contains everything you need to know.

NOTE: Your photos are only shown during MemberShare and will be deleted afterwards. We do not keep copies. There is no need to watermark your photos. If you feel that you must add a logo or other overlay, please keep it small and unobtrusive.

Also, please do not wait until the very last minute to submit the photos you want to share. We need time to prepare the image presentation. When the MemberShare is especially popular, we may have to reduce the amount of images from each member. If that happens we will announce it before MemberShare begins, and hope for your understanding.
