This year we have a long and rather mild autumn. Still there has hardly been any days with minus degrees. So there is still ample opportunities to get the nature in autumn colours.
There are some small rivers in the near area that are accessible and that provides good hills with trees that are bright yellow and reddish in colour.
When it comes to water and freezing movement without blurring it, the key is to have just enough exposure time. Usually between 1/2 and 1 seconds.
This is the camera on the tripod ready to take the photo. Here I also have a different challenge. The river is much brighter then the background hill.
This challenge I solve with a filter. I like the Lee filters. I have a gradient set of ND filters, and here I used the 0.9 ND Gradient Filter.
So then I did a photo with the filter on and tested with different exposure times. Ended up with an exposure of 1/8th second, probably because the water runs fast here.
