Lower interval values will result in slower
time-lapse videos. Note that a too short interval may limit your exposure
range.

Make sure your camera ISO is not set to "Auto". Doing so may interfere
with bulb-ramping.

Disable Mirror Lock-Up mode on your camera. Pluto Trigger cannot
ensure correct exposure timing in Bulb-Ramping mode with Mirror
Lock-Up enabled.
5.
Disable automatic focusing on your camera, choose a fixed aperture
and set ISO to the same fixed value you used when measuring your end
exposure as described above. If you did not pre-meter your end
exposure, use any ISO setting such as 200. Do NOT use automatic ISO
feature, if available in your camera.

Set your camera to Manual exposure mode, take a few test pictures
and pick a shutter speed that yields an acceptable picture.

Turn on Bulb-Ramping and the parameters will show up.

Enter the "End Exposure". Make sure the end exposure is shorter than
the Time-Lapse Interval.
