camera mapping

Using Andrew Price’s camera mapping tutorial as a guide, I am perplexed as to why my photo projection is both blurred / anti-aliased and darkened. I’ve scrounged the material settings to no avail. Screenshot. Help?

Just want to point out:

  • texture > image sampling > MIP mapping: off
  • texture > image sampling > interpolation: off
  • render > anti-alias: off

So, why is it blurring the projected image? Here is the .blend file. Anyone?
