Arlington Meeting Info & Maps       


The program planners for our First Wednesday PATACS meetings in Arlington are looking for topics that members would like to have explored or questions answered - this is your opportunity to have a say in subjects addressed at this meeting. This is a smaller meeting than the Fairfax meeting, and it allows for much more interaction between members than is possible in Fairfax. And – there's the post-meeting Pizza and Salad SIG, the post-meeting social at a nearby restaurant - another value-added feature of your membership! Please send your suggestions to our meeting program planners at arlmtgpgm@patacs.org.

Automotive 3D Printing

3D Printer
3D Printing –
What’s All the Hype About?

Presented by
John Acton

Is 3D printing a passing technological fad or could it be a window on a technology future that will change the way we live! I know this is a bold and provocative statement, but I hope that after you listen to my presentation, you will agree with me that 3D printing may prove to be one of those pivotal technology advancements that have a profound influence and impact on our economy, culture, and society, far beyond what anyone expected during its early evolution.

Printing has evolved over more than 40,000 years of human evolution, all aimed at storing and conveying information. From cave paintings, to numbers and symbols, to alphabets, the whole process was to convey a message. Printing as we know it, i.e. from Gutenberg’s printing press in 1440 AD to today’s laser printers and the internet, etc., are all about making dissemination of that message easier.

3D printers are different, they aren’t about conveying a message, they’re about conveying an object. In the next hour and or so, we’ll take a whirlwind look at the amazing range of things 3D printing is being applied to and what the implications may be for our future. We’ll look at the rapid expansion of 3D printing technology and its applications in architecture, medical, automotive, aerospace, military, fashion, food, and other fields. But most importantly, we’ll look at what could be a coming inflection point that portends a radical shift in how we work and live.

John has been an OLLI member since he retired in 2012. He is the chair of the OLLI Science, Technology, and Health Program Planning Group. After graduating from the University of Connecticut in 1968 with a Bachelor’s Degree in Electrical Engineering, John spent 20 years as an R&D engineering officer in the U.S. Air Force working on a variety of programs in advanced sensor technology applications. He obtained his Master of Science in Engineering Management of Technology, from Northeastern University, while on active duty, in 1971. After retiring from the Air Force in 1988, John spent the next 24 years as a support contractor for a variety of Defense and Intelligence communities, spending his last 7 years working for the Director of National Intelligence.

Exposure Controls for Adjustable Cameras:
What they are and how to use them
Presented by Henry Winokur

The presentation will talk about the 3 major exposure controls used by adjustable cameras. Illustrations and example photos will be shown illustrating what they control and how to use them and why specific settings were chosen. Hopefully we’ll have time for questions and answers.

Henry S. Winokur is a DC native and has been taking photos for over 50 years!!! (He is amazed to be able to say that!) From about 1966 until 2005, when he switched to digital, he has always had a darkroom nearby. He has experience working in both monochrome and color. He has always done is his own processing and printing. Prior to 2005, Henry worked primarily with SLR (Single Lens Reflex) equipment, in both 35mm and 645 formats. Since 2005, he has only worked with DSLR (Digital Single Lens Reflex) gear.

Until he switched to digital in 2005, he used mainly Nikon SLR equipment, but he also used a Bronica 645 SLR system for several years. When he switched to digital in 2005, he took the opportunity to change from Nikon to Canon, because at the time Nikon had not decided to go digital. He started with a Canon 20D, moved up to a 7D (the prior 2 cameras are not full frame 35mm), then a 5D Mark III (5d3) and today uses a 5D Mark IV (5d4). He has only one body and 3 lenses: a Canon 16-35 f/4 L IS USM, his “normal” and favorite lens, a Canon 24-105 f/4 L II IS USM and a Canon 70-200 f/4 L IS USM (IS = Image Stabilized, USM = Ultrasonic Motor. “L” lenses are Canon’s best lenses.)

Henry uses Adobe’s LightRoom CC and Photoshop CC as his photo organizing and processing software packages. He has an Epson Stylus Pro 4900 printer. He prints a lot—usually 5-10 images at a sitting—which doesn’t sound like much—but his prints are at minimum 12x18”. One of his favorite types of image is the multi-frame panorama. He has printed images that are 12 feet (yep, feet) long. He is currently working with images he shot on a trip to Iceland and Greenland in July. He has just returned from a trip to Spain and hopes to get to those images in the next few months.
