Camera Analysis ...

What color photography ?
  • This 400x400pix TIF image is a Photoshop crop of a 40D photo.
  • The TIF was then down-sampled to 35x35pix which is similar to a ideal camera's RAW mode. The TIF image was also converted to JPEG.
  • Remember, the CT-EyeChart© 50% readability reference is 35x35pix.
  • Therefore, this 35x35pix image has the same resolution as in the test pattern.
  • So, JPEG compression is a minor effect.
