A few interesting DSLR camera videos…

A handy video guide to using an off camera flash with a D300 and an SB-800 flashgun.

And a 12:37 minute video of taking pictures of birds.

Even though I’m not around zoos or aviaries much, the video was worth watching. The one trick I learned was how to take a picture through a cage/aviary without having the bars/cage in the shot.

Both videos come out of the UK from PhotoAnswers.co.uk. A web site I’ll add to my bookmarks.

Old school WPF syntax revisited…. GradientBrushes

Remember this syntax from the early days of Avalon/WPF/XAML?

<Rectangle Width="300" Height="200"
    Fill="HorizontalGradient Blue White" >
</Rectangle>

Very simple — easy to create Gradient Brush. But, it was removed from Avalon/WPF in part due to it’s challenge for tools (parsing, etc.).

Mike posts a simple MarkupExtension that although it doesn’t mimic the old syntax identically, the spirit is there.

<Rectangle Width="300" Height="200"
  Fill="{local:RadialGradientBrush red, blue}" />
