This tutorial video looks at how to easily create a Bad Pixel Map (BPM) in APP. The benefits of a BPM are considerable and work well to remove hot and cold pixels, and so in many cases will negate the need for a darks library for hot pixels. The BPM can also be used to remove bad column defects.

What you will need

  • 5 dark frames
  • 5 flat frames

Once you have used these to create the BPM then you won’t need them again. Using a bad pixel map is a sure-fire way to improve your data.
