The famous nocturnal Hex hatch of the Midwest (and a few other lucky locations) stirs to the surface mythically large brown trout that only touch streamers for the rest of the year.
A great desktop background picture invites you into some beautiful scenery while still making it easy to see the icons on your desktop. Simple compositions create large uniform areas in the image, but the patterns are still intricate enough to be fun to stare into. People who use multiple desktops or monitors in MacOS, Windows, or Linux can never have too many backgrounds to help keep the different desktops straight.
I've arranged some of my best background-friendly photos, from trout streams and other scenery in Alaska and the American West, into packs you can conveniently download together as zip files for a small fee and load into the folder where you keep your desktop backgrounds on your computer. These packs include the highest-resolution, unwatermarked version of each image.
