Light painting... 
This typically is done in dark settings and was something I could try in my home when the February 2021 weather was so uncooperative.  Here I took a Peace Lily and placed on a table in a darkened room then "painted" it with a dim flashlight over a period of several seconds to make it visible and achieve the desired affect.  Had I used a camera flash everything would have been lit and had a completely different look. This produced and almost 'stage' like appearance.

A typical use of long exposure in landscape photography is to slow moving water down. Typically this also involves neutral density filters to cut back on some of the day light without changing the colors, allowing a longer exposure to blur the moving water and show its motion in a still image... that's right I did not have any of those but took a stab at it anyway the water in the images below should look a little smoother as you go from right to left.  This was the only place accessible along the stream with moving water, every other place it was frozen over. Not very photogenic but I gave it a try

Sunset with a Bonus
Finally to incorporate my sunset theme I went out on the one decent day we had and stood on a bridge overlooking Interstate 81 facing the west and set up for a long exposure trying to capture the late day sky above and the head lights and tail lights of the traffic below.  The one thing I did not consider was there might not be much traffic on that Sunday during the "big game".  Not to be beaten, I took the first six photos and stacked them to create the seventh.  The last two were on a different day looking in the other direction, with more traffic they turned out fine.
