The photo presented above was provided by Chattanooga Attorney David Hawley and scanned at 2400DPI. The resulting details are remarkable. We can compare it to a digital printed copy of the same photo that was previously scanned. The blue button above allows you to see the difference.
All the 'zoomable' photos on this website are from film, and either scanned as negatives, or analog prints. We can explore their abundance of resolution to find new details never seen before.
Never throw away original photos. They contain far more details than you may realize.
Always keep full sized, original digital photos.
Prior to digital photo printing (~late 1990s), analog prints were continuously variable in tone. Today, all digital prints are made up of tiny dots that, when viewed by human eyes, look continuous, but only at the intended printed size. That standard is 300DPI (dots per inch). There is no room for enlargement from a digital print.
