Here's some more with the my 645z and 28-45.
Skies were held back using a Lee 0.75 GND soft filter. I prefer filters over exposure blending. Easier and less hassle. All processed in the excellent DXO photo labs 4.

Why nothing inbetween - well - wind. That tree was moving around a lot so had to time my shots carefully then keep the best ones where the branches didn't have any moving. At 50mp and at 100% view this takes a little time. I like to take a burst of 3 when the wind is calm so I can see if the branches have moved at all between the sequences at 100% view. If they all superimpose - then you know you've nailed it.
On the way back I made a stop at Lochan na Stainge - it seemed calmer there but the cloud was low hiding the peak of Meall a' Bhuiridh
That little spec of white is the snow capped peak beginning to emerge as the cloud burns off.
I took a few with idea's for different crops. Here's a 2:1
