One way to create 'soft light' is to use a diffused light source. Luckily, the clouds were diffusing the sunlight just right today so I went downtown to see what I could find.
The Hemphill Wells parking garage used to be for a huge general store that can be traced back to the 1920s. You can think of it as the Wal-Mart of the time. Now it is just parking for the nearby banks.
