Sitting out in the backyard and looked up to the sky and noticed a halo around the sun. Grabbed my camera and took 5 photographs using a balustrade and then a tree trunk to mask the sun itself. Two of the photographs are shown below.
I added all five images to my iPad. Processed the two below using PhotoPal and uploaded them to the web server using GoodReader. I then added the images to my WordPress uploads folder using the Add From Server plug-in. That is when the images are crunched and resized by WordPress for publishing. Neat. Love the Canon SX20 and the iPad.
