Pluto Trigger - Manual (Page 20)

5. Disable Mirror Lock-Up mode on your camera. Pluto Trigger cannot
ensure correct exposure timing in Bulb HDR mode with Mirror Lock-Up
enabled.
6. Disable automatic focusing on your camera. You may also need to set
it to Single drive mode. Quiet or Silent mode is also acceptable, if
available on your camera.
7. Start Pluto Trigger app on your phone; connect to Pluto Trigger with
Bluetooth; switch to HDR mode.
8. Choose the Mid Exposure and other sequence parameters. However, in
HDR mode extra care needs to be taken. As you make changes to the
settings, the exposure from the HDR sequence may falls out of possible
range. Due to using Bulb mode, any shutter speed faster than 1/20
second may not be able to trigger your camera. When shooting
daylight photography and other bright scenery, ND filters may be used
on your camera to darken the scene and make the resulting exposures
longer.
9. Press "Start" button and a series of images will be taken.
You can use image-processing software to combine these pictures and
create an HDR image.
NOTE : You’d better turn “Image review” off on your camera. Otherwise,
Pluto Trigger may not be able to take all the photos.

TAR TRAIL
Star Trail mode can be used to take long-exposure image sequences of
the night sky. These long-exposure images can later be combined using
image processing software to create a night sky picture with beautiful star
trails.
