So it turns out the default header image was making it impossible to read the site header. So we talked for a few minutes and came up with the idea of a glass of beer on a scarf.
So I got out the tripod, setup a nice shot, took several minutes to get a good glass of beer poured (from our last batch of over-carbonated homebrew), played with the exposure a bit, and generally took a bunch of pictures to make sure I got at least one good one.
Then I took the camera off the tripod and took one last picture by hand. So of course that was the best one and the tripod and all that fiddling was a waste of time…
Perfect header! Worth every (unnecessary) minute…
