So.........
When a small object moves in a viscous medium it experiences a resistive force that is opposite in direction to its velocity and directly proportional to its speed.
As time gets large, the exponentials become 0, so the first term vanishes and the second term becomes -VN, the natural (=terminal) velocity in the downward direction. This happens whether the object up initially (v0 > 0), down initially (v0 < 0), or just dropped (v0 = 0).
Full frame. Dedicated macro lens. No crop. No post processing.
