Presenter: Jim Harp
This workshop is designed for people who are wondering what all this fuss is about "VR." We’ll discuss what the terms "Virtual Reality," "Augmented Reality" and "XR" mean and how they are relevant to 3D photographers and enthusiasts. We’ll look at the various VR headsets currently available on the market with a focus on the needs of 3D and immersive photographers wanting to share and view their work. We’ll also take a look at the various 3D 180º and 360º cameras currently available and their output formats.

Conversion Control
Thursday, Aug 13 2:30PM - 3:00PM PDT
Presenter: Jim McManus
Learn a fast & effective approach to doing 2D-to-3D conversions, using just a few common software tools (I use Photoshop, but the concepts apply to other graphic editors too). I’ll share many useful & time-saving tips, including using an anaglyph "Live View" workflow for true real-time 3D control and instant feedback. Also discover ways to improve your stereo 3D photos too, like fixing sync errors or enhancing depth.

3D on Social Media SIG

Using Photoshop to Colorize Your Black and White Stereo Cards
Friday, Aug 14 3:30PM - 4:00PM PDT
Presenter: David Richardson
This short presentation will demonstrate simple techniques to allow you to apply realistic color to your images and bring back to life your digital collection of stereos.

External Flash and Making a PoleTop Trigger for W3
Friday, Aug 14 4:00PM - 4:30PM PDT
Presenter: Jay Kusnetz
First part is how to use an external flash with cameras that do not have a flash hotshoe but do have a built-in flash. Examples will show use for sunlight fill, lessen the impact of dust/smoke, etc...
Second part will show the gizmo that I made which sits on top a Shur-line 9 foot pole. It allows me to press the shutter on the W3, and has a camera to let me see the screen on an external monitor at the bottom of the pole.

Modern Stereo Card Assembly Revisited
Saturday, Aug 15 12:00PM - 12:30PM PDT
Presenter: Tom Dory
This workshop will review in detail different methods to make modern stereo cards. Details on how to set the stereo window, print and trim the images will be discussed. The cards can have the look of antique cards with a modern twist by creating unique front and backs. The use of SPM will be shown to align and color adjust the images. Methods to mount the front and back backgrounds on card stock with alignment will be shown. All in 30 minutes!

Photoshop Layers for Easier Adjustments and Compositing
Saturday, Aug 15 12:30PM - 1:00PM PDT
Presenter: David Kuntz
Photoshop layers enable you to make changes to a photo which can easily be subsequently modified or undone which simplifies the editing process. Plus, they’re the key to making multi-image composites. This workshop will explore the basics of layers, layer masking, adjustment layers, and layer blend modes.

View-Master SIG
Saturday, Aug 15 3:30PM - 4:30PM PDT
Moderator: Wolfgang Sell
The View-Master Special Interest Group meeting has been a fixture at the NSA convention for many years. We'll have news about View-Master collecting, remind everyone of the great work Image3D is doing, and even see a small presentation about View-Master. This year we will see the Salesman's Pitch Book and its use to sell View-Master in the 1960's. Maybe a fun surprise as well. Come join us!

3-D Phone/Tablets SIG
Sunday, Aug 16 10:30AM - 11:30AM PDT
Moderators: Andrea Shetley/Linda Nygren
This SIG is for showing and discussing various 3D phones (for viewing and/or photographing) and tablets, including hardware, apps, and viewers. We also will discuss how to make 3D images on your regular smartphone. This is an open discussion format to ask questions, share information, and give tips.

Optimizing Anaglyphs for Online Meetings
Sunday, Aug 16 12:00PM - 12:30PM PDT
Presenter: Jim Harp
With the current prevalence of online meetings, many of us are having to present our work in anaglyph format whether we like it or not. This workshop will look at the anaglyph creation tools provided by StereoPhoto Maker and explore how to use them to make your images work as well as possible in Zoom and other web-based platforms. We’ll also discuss using SPM in conjunction with Photoshop or similar image editors to make color images look as good as possible. Beginners welcome!

3D Photography with Twin Cameras
