Make a postcard of your favorite panorama! See the sample at the bottom of the page. We create a 8 1/2" x 11" PDF with the front and back of four postcards: the view from the panorama's vantage point, the sunrise and sunset times and positions throughout the year, and the position and time of the rising of the year's full moons. We've been printing them on 100lb. card stock on an inkjet printer.
The sun and moon rises and sets are particular to the location, for example if there's a mountain to the southeast, the sunrise and the rising of the moon will be later than if the horizon were flat.
The current plan is that we show a low resolution PNG, and then you can buy the full resolution PDF using Paypal or Venmo. During this beta we'll send you the PDF if you email us with your comments and and thoughts about pricing (and the ID that you'll see next to postcard image when the computation finishes).
A panorama that you have previously computed
or a public panorama
Be patient; the computation can take minute or two.
and "Sunrise at ..." so you may want to edit it here.
Twenty or fewer characters looks best.
