Hi,  Thought I'd share a star trail and ML & photoshop settings.

ML settings

Exposure 20 seconds (ISO 800 f4)
Intervalometer photo ever 30 seconds

Photoshop

Import each frame into photoshop stack (File, Scripts, Load Files into Stack)
Select all layers
Select blending mode to Lighten
Add a threshold adjustment layer and adjust as desired
Add a curves adjustment layer and adjust as desired ( I used the double arrowed icon on lhs and dragged down on a dark area)

notes

There's quite a lot of light pollution where the shots were taken.  the bright trails show the stars of Ursa Major  (big dipper)

Hope you like oh and btw I'm using the beta of Canon 100d

Hi,

I'd like to use trap focus on my eos 100D to take a picture when a subject comes into focus.  I currently don't see this option in focus menu

I get:
Focus Follow
Focus Endpoint
Rack Focus
Focus Settings
DOF settings
Focus patterns

From the User Manual I can see:

'Activating AF mode dialog when Manual Focus is active will toggle Trap Focus'

How do I activate autofocus mode to see this menu option please? 
I'm using the beta build for EOS 100D BETFW1012017Jan06
