tiny

Etymology

From Middle English tine, tyne (“very small”) + -y. Perhaps from tine.

adj

1. Very small.
   Not long ago, it was difficult to produce photographs of tiny creatures with every part in focus. That’s because the lenses that are excellent at magnifying tiny subjects produce a narrow depth of field. A photo processing technique called focus stacking has changed that. 2013 July-August, Catherine Clabby, “Focus on Everything”, in American Scientist
