Does anyone use the multi-frame noise reduction? And if yes, is there a significant reduction in noise at ISO 3200 and above vs single shot? Thanks!
 
I have heard of this from a photo competition judge here in the uk, he reckons it is great and works well even with low iso shots.......increasing clarity.

  1. Open each of the images in your stack as layers in Ps.
  2. Align them (Edit → Auto-Align Layers…). Auto should work fine here.
  3. Select all of the layers and turn them into a Smart Object (Convert to Smart Object).
  4. Now apply the Median Stack mode (Layer → Smart Objects → Stack Mode → Median).
Not tried it myself yet but interested to see if it works. It is on my to do list in the next week.
 
The Cortex camera app for iPhone and Android does that automatically, and it works great with static subjects. I haven't used the method seriously though, using PS and a real camera.
