I'm exploring the world of the very tiny landscapes with a NiSi close-up filter added to my Tamron 90mm macro lens. Also added a rail for framing the subject.  Check out the video about the products and subjects I shot.  https://www.youtube.com/watch?v=sEaUFS-novg

The image you see below, the subject that looks like a tree branch is the size of my finger nail of my forefinger, and I was able to almost fill the frame. By adding the close-up filter I am able to shoot in much closer then with the macro lens without the filter.
