About Me

Sam Hall

As a Chattanooga area native I have a personal appreciation of the city’s remarkable renaissance that has occurred over the past 30 years. Vivid childhood memories of flame-throwing smokestacks and pungent smells of foundries have given way to a revitalized downtown that has embraced its history.

I’ve long had an interest in history - studying family genealogy starting in my mid-20s, and was always been fascinated by historical area photos. See HallHistory.net . Other than bagging groceries - my first jobs included radio disc jockey positions in various formats starting at age 16.

After graduating from the University of Tennessee in Knoxville with a Bachelor of Science in Communications - I returned to radio for 12 years in sales & management.

I then spent over another decade in technology sales and marketing and currently work again in advertising & marketing. In the early to mid-90’s I embraced the new ‘Internet’ - registering domains for the radio stations I worked for, building their first web sites, and ensured we were the first stations in the market to stream live.

About Deep Zoom

The namesake and core technology for this site was developed by Sand Codex, later renamed Seadragon Software and acquired by Microsoft in 2006. Deep Zoom provides the ability to interactively view high-resolution images.

Microsoft decided to focus efforts into Bing and shut down their ‘Live Labs’ division; including Seadragon. Fortunately it’s code was released as an open-source library called OpenSeadragon, a pure JavaScript implementation of the technology.

Things I do...

My First Deep Zoom

In 2010, the Library of Congress released a collection of 8x10" glass-plate negatives scanned at very high resolution. A series of four plates covered a panoramic view from Cameron Hill, circa 1902.

Each image was over 80 Megapixels in size. I was amazed at the level of details of these 100+ year old photos. However, each file was so large it could cover 30 Full-HD monitors to display at 100% size. Deep Zoom provided a unique way to do this across multiple operating systems and devices.

Each image presented is first cleaned up and clarified as much as possible through work in Photoshop.

Click the red square in the 2nd image to see how small of an area would fill an HD monitor.

Photography: a Time Machine

Despite all our current ways we can capture photos, negatives from over 100 years ago can contain far more resolution and detail. A negative (or positive slide) can be scanned to reveal more information than any print or postcard produced from them. Zooming into the images of the past in such detail gives one a sense of being there.

If you could go back in time with a camera and were given only a few minutes to capture some photos, you would probably want to protect and preserve those images, maintain the best quality possible and make backup copies. We are actually given this very opportunity today - everytime we take a photo. It becomes a record of the past.

  • If you have negatives or slides - don't throw them away or store them in the attic.
  • Download images from your digitial cameras & smartphones and back them up.
  • Save ORIGINAL images, not the copy you attached to a text or social media post, as those are compressed and reduced to digital mush.
  • Look for your photos and ask your relatives if they have a 'box of photos' (or better yet - negatives). Go through them and record who is in the photos, where and when taken, etc. That information could die with them otherwise.
  • Digitally scan photos and negatives at as high a resolution as possible. Example: a 35mm negative or slide should be scanned at least 2400dpi and up to 6400dpi if your scanner supports it natively.
  • Take uncommon photos.

Take Uncommon Photos

Let's face it - posed people smiling for the camera, dogs, cats, and flowers will be very uninteresting as time goes on.

Take a moment to photograph the larger scene of the street, an event, or anything that may seem normal in this moment in time. In only a few decades it will become more and more interesting.

I purchased my first 'real' camera while a senior in High School. One day I took it to school and took random photos of hallways, the cafeteria, cute girls, etc. My only wish is that I had done that a dozen more times as they are pure gold today.
