How Does the Lens Create an Image on the Sensor?
What is projected onto the sensor from the lens? How focussed is the image?
Sharp or Unsharp depends on tiny circles
Each tiny point of light that reflects off our subject is projected onto the sensor. How it comes out in the final image, sharp, or ‘unsharp’ depends on something called the ‘Circle of Confusion’.
The new term is fully explained in the the new entry to our Glossary of Photographic Terms. Now you can find out all about the ‘Circle of Confusion‘.
