In 2001, most computer monitors had a resolution of 800x600 or 1024x768. Broadband was rare; dial-up was king. Hard drives were measured in gigabytes, not terabytes. Yet, O’Rear shot "Bliss" on medium-format film. The original scan was a whopping (astronomical for the time). Microsoft downsampled it to 800x600 for the default installation.

If you close your eyes and think of the early 2000s, the visual landscape is defined by a single, specific shade of green. It is the vibrant, impossibly lush green of a grassy hill rising gently against a piercing blue sky dotted with perfect, cumulus clouds. It is "Bliss," the default wallpaper of Microsoft Windows XP, and arguably the most viewed photograph in the history of the medium.

"I was driving down the road, I see this hill, I see the clouds, I see the grass. It’s a beautiful day," O’Rear recounted in interviews years later. "I pull over, I get my camera out, I put the Kodak film in, I take the picture."

When Windows XP launched on October 25, 2001, the wallpaper instantly drew attention. The saturation was intense; the colors were hyper-real. The green of the grass seemed to pop off the screen with a vibrancy that nature rarely produces, and the sky was a uniform, calming blue that looked almost artificial.
