Artists Paint Pot Trail Panorama, Yellowstone National Park (click to enlarge)

Here is a panorama image of the Artist Paint Pot Trail at Yellowstone National Park.  You can see the boardwalk that meanders through a small geyser basin.  The trail then climbs up a ridge line to an area with several “paint pots”.  Paint pots are pools of bubbling mud that make interesting patterns for photography.  As an added bonus, they are just mesmerizing to watch!

The original of this image is 110 inches wide by 26 inches tall.  The Photoshop .psb file is 1.5gb.  When I first saved the file, I expected Photoshop’s usual .psd file extension.  Instead, I got a .psb file extension which I did not recognize.  A quick search found the answer:

PSB files are a large document format similar to a PSD file but for a larger image size. The largest image size supported by a PSD file is 30,000 by 30,000 pixels. PSD file support has to be enabled in Photoshop’s Preferences pane first, then PSB files can be saved at an image size up to 300,000 by 300,000 pixels.

The original image is 32,930 x 8,183 pixels at a resolution of 300 pixels per inch.  So, that explains the .psb file extension…
