In May, a collection of more than 400 glass plate negatives depicting life in Chattanooga during the late 19th century was discovered. And now, a private collector has donated an additional 67 photos thought to be from the same collection. 

A portion of the collection has been published as part of a series on Deep Zoom Chattanooga and featured on Picnooga, two history websites.

The photographer is thought to be Charles Gustavus Walline, an employee at Chattanooga's D.B. Loveman's Department Store at the time the photos were taken between 1898 and 1900.

The smaller collection of 67 photos was obtained through networking. Recently, Deep Zoom founder Sam Hall was contacted by Charlie Coulter of Signal Mountain, who obtained six boxes of glass plate negatives at an auction in Walker County more than 45 years ago.

"Charlie explained he wanted to donate the plates and only wanted scans in return," Hall said. "As I scanned them, I noticed something pretty amazing."

Hall said many of the photographs contain the same people and locations as those in the previous Walline collection.

Could the photos have been taken by the same photographer? The answer is a firm maybe, according to Hall.

"My theory is it was a friend and/or co-worker who was also into photography," he said. "After all, around 1900, anyone could get into photography affordably. I spent more on cameras/gear and took more photos in my 20s than any other time in my life, so it's likely this was the case back then, too."

For now, the photos will be attributed to Charles Walline and the Walline collection, although Hall is planning to do more research.

The full collection will soon be available on both Picnooga and Deep Zoom Chattanooga. 

In the meantime, Nooga.com has been offered several preview photos from the collection for this article. 

A portion of the larger Walline collection was also released on Mashable. Other photographs can be viewed here and here.

Picnooga is seeking to obtain more glass plate negatives. Glass plate negatives offer the highest resolution possible. This makes them great candidates for the Deep Zoom technology.
