Compressed Ice Water
Warren, Connecticut. Context is everything. Take a round glass, put ice and water into it but take a picture of it in such a way that it looks flat on its background and the context of a glass of ice water is stripped away. In photography the loss of depth or three dimensionality from the use of a telephoto lens is called compression and that's a fitting word for what seems to be happening here, both in depth and inside the glass.
Note: this is not a crop of this image, it's another shot from closer range.
