Getting sufficient depth of field can be particularly challenging in macro photography, because depth of field is smaller (shallower) for objects nearer the camera, so if a small object fills the frame, it is often so close that its entire depth cannot be in focus at once. Depth of field is normally increased by stopping down aperture (using a larger f-number), but beyond a certain point, stopping down causes blurring due to diffraction, which counteracts the benefit of being in focus. It also reduces the luminosity of the image. Focus stacking allows the depth of field of images taken at the sharpest aperture to be effectively increased.

Secessio plebis (withdrawal of the commoners, or secession of the plebs) was an informal exercise of power by Rome's plebeian citizens between the 5th century BC and 3rd century BC., similar in concept to the general strike. During the secessio plebis, the plebs would abandon the city en masse in a protest emigration and leave the patrician order to themselves. Therefore, a secessio meant that all shops and workshops would shut down and commercial transactions would largely cease. This was an effective strategy in the Conflict of the Orders due to strength in numbers; plebeian citizens made up the vast majority of Rome's populace and produced most of its food and resources, while a patrician citizen was a member of the minority upper class, the equivalent of the landed gentry of later times.

Tree-ring dating indicates that construction and refurbishing of Cliff Palace was continuous approximately from 1190 AD through 1260 AD, although the major portion of the building was done within a 20-year time span. The Ancestral Puebloans who constructed this cliff dwelling and the others like it at Mesa Verde were driven to these defensible positions by "increasing competition amidst changing climatic conditions". Cliff Palace was abandoned by 1300, though debate is ongoing as to the cause.

Cliff Palace is the largest cliff dwelling in North America. The structure built by the Ancestral Puebloans is located in Mesa Verde National Park in their former homeland region.

Carhenge is a replica of England's Stonehenge located near the city of Alliance, Nebraska, in the High Plains region of the United States. Instead of being built with large standing stones, as is the case with the original Stonehenge, Carhenge is formed from vintage American automobiles, all covered with gray spray paint.

It is also called "nut tag", "bag tag", "sack whack", "bell flicking" and "roshambo", the last name coming from an episode of South Park that featured the practice.

Sack tapping is a slang term for a game where a participant attacks, by slapping, tapping, punching, kicking, elbowing, twisting, or backhanding a victim's testicles. The term derived from 'sack', slang that refers to the scrotum, and the activity is a form of groin attack. This sociological manifestation of bullying can result in severe testicular injury that may require amputation as the only form of treatment.
