Diane DeRogatis

My name is Diane DeRogatis and I am a certified art educator.  I am originally from New Jersey where I taught Elementary and High School art.  Since moving to Pennsylvania I continue to teach and work independently as a freelance artist.  The mediums I love working with are watercolors and acrylics.  Being a landscape artist I am totally inspired by the beautiful lakes, mountains, hiking trails and farmland of PA.

They had me at “Lights Off”…  I was 10. 
I was in the first day of a darkroom class at my local Y,  and the magic of seeing a print develop as I watched has kept me in a darkroom ever since.  I’ve been a working pro photographer now for almost forty years.  Although it’s now electronic, I’ve been using the “digital darkroom” of Photoshop almost every single day for the last twenty years, both in business and in teaching digital in Temple’s Continuing Ed program.   I was also part of the adjunct faculty at Widener University as well as working at MontCo, Delaware County CC and Penn State.
Our programs will be an introduction and overview of the tools and techniques available to edit, correct, combine, colorize or create a classic B/W image, layout a wedding album or publish a company newsletter, take ex-spouses out of family photos, publish and finally print your own fine art images, so bring in a few samples to work on.  Anything you can think of doing to an image or with an image can be a reality with a little Photoshop magic!  Let’s play!

Gabrielle Sivitz

Originally trained in scientific illustration, Gabrielle Sivitz credits her father, a science teacher, amateur photographer and painter, for shaping her lifelong enthusiasm for nature and art. As an educator and artist, she has held positions at the Academy of Natural Sciences in Philadelphia and Bowman’s Hill Wildflower Preserve in New Hope. Gabrielle studied at Bucks County Community College, Moore College of Art & Design, and the Pennsylvania Academy of the Fine Arts where she focused on painting and printmaking. Gabrielle recently returned to eastern Pennsylvania after 15 years living in the Intermountain West, where she taught drawing and painting to adult students out of her own studio as well as at art centers and museums in Idaho and Montana. In 2017, she was awarded a professional
development grant from the Idaho Commission on the Arts with the National Endowment for the Arts. Gabrielle wants her students to enjoy art and embrace the learning process. Her classes and workshops are geared toward having fun and accepting mistakes. “When we’re kids we naturally draw and paint for fun and we don’t worry about the results, but as we get older we become much harder on ourselves. We accept the myth that artists are born with some magical ability that we don’t have, and so we give up. In reality, it just takes practice. It’s all about training yourself to see like an artist, and having fun along the way.”

Doug Tweddale

I have been an artist my whole life. I remember being nine years old and oil painting with my Uncle Lester Gallagher, an artist from the Midwest who loved painting the sand dunes of Lake Michigan. For the last 30 years, I have been a pastel artist, and for half of that time I have studied with Master Painter Albert Handell. Now that I have retired, I have the wonderful opportunity of making painting my first priority as I travel this beautiful country with my wife Sue. So far, we have been on two three-month extended trips to many National Parks out West. I’ve attained signature member of the Pastel Society of America and the Pastel Society of the West Coast. A story of our 2015 journey and my travel art work was just published in the August issue of the Pastel Journal. During our travels, I conduct “Living the Dream” Plein Air Workshops to share my artist’s knowledge and experience with students as we enjoy painting our treasured National Parks.  dougtweddale.com
