This Month’s Subject: Technology 4 Life

Linda Siegel and Nicole Engler founded Technology4Life, a nonprofit project of MarinLink, a 501(c)3 organization ( This technology teaching organization for older adults helps clients use technology to enhance their daily lives. As a Computer Science major at UC Berkeley, Linda hadn’t considered a career in film, but an internship at Skywalker Ranch as a database consultant led to more than 20 years at Lucasfilm. As a digital artist, she was responsible for lighting and compositing for feature films, earning credits on films such as “Forrest Gump,” the “Star Wars” prequels, and “Pirates of the Caribbean.” She was fortunate to work on the feather shots of “Forrest Gump,”which at the time were the longest computer graphics ever created.

More recently, Linda was responsible for technical training and artist management for LucasFilm, ImageMovers Digital, and other leading animation and visual effects studios. She created training in software and production techniques, artist enrichment, and development programs as well as outreach to educational institutions. Linda works with adults in the Whistlestop Computer Lab as well as offering one-on-one consulting and computer support. She creates interactive, practical education and ensures students can use and apply their knowledge. She also volunteers with Whistlestop’s Meals on Wheels program. Linda earned her B.S. in computer science at U.C. Berkeley and her MBA from Cal’s Haas School of Business. She lives in Marin County with her husband, author Sheldon Siegel.

Weekly GGCS Announcement


Week of September 18 to September 22, 2017


Third Wednesday, 1:30 PM at the GGCS Classroom

Wednesday, September 20, 2017 

Michael Brunsfeld Will Present Creative Uses of iPad Apps with Photos—Part 2(an extension of the Presentation given on April 19, 2017)

Michael Brunsfeld is an Illustrator, Art Director, Photoshop Instructor, and a member of the Marin Photo Club, and would like to demonstrate and explain his mobile workflow. Over the last five years, Michael has made it a habit of posting everyday an “Altered FoTo” to Flickr, FaceBook, Instagram and other sites.  In this process he has explored the simplicity of using mobile devices, techniques and apps and now is rarely bound to the desktop.

First he transfers photos from his cameras via wifi to the iPad. There he develops” the image by using Google adjust value and color and remove unwanted items.  Then he creates a number of “filtered” variations— using apps like Dreamscope, Prisma or Moku Hanga,  Finally, he opens up his favorite all-around app called iColorama and composites together elements that he has just created by first creating masks to assemble the best bits together, then altering local color, value and especially texture for a final image that departs from the “reality” of the original photo in favor of something . . . painterly, illustrative and unique.

Directions to Classroom:  Mission and E Streets at the rear of the First Prebysteran Church down four steps on the right.

There is a $5.00 charge for non GGCS members.
