Anyway, blue screen of death. New computer, new software, blah, blah blah. Here's how it all comes around to cake: I have learned to take better pictures. :-)
The large box as a background worked for a long time. But a white box began to show marks from where I slid the cake across to the center. Marks I had to photoshop out. After looking at pictures from other bakers, I decided to try the black background approach. $2 at The dollar tree for two sheets of black foam board. And wah-lah, better cake pictures! No photoshop needed.
I guess a little change can be a good thing!
