Regarding steam locomotives, does smoke or steam come out of the smokestack?

Answer: Both.

*The smokestack is where all the expelled smoke from the burning coal in the furnace goes, but pressurized, used steam from the cylinders also exhausts into the smokestack and creates a draft in the system which in turn draws air into the furnace to assist in renewing combustion. Furthermore, there is usually a device called a blower, which blows live-steam directly from the boiler straight up the smokestack. This is can be turned on and off as required to assist with the draft in the system.

+Water vapor is the gaseous phase of water. It is only one state of water within the hydrosphere. Water vapor can be produced from the evaporation or boiling of liquid water or from the sublimation of ice.  Hydrosphere: all the waters on the earth's surface, such as lakes and seas, and sometimes including water over the earth's surface, such as clouds.

Some Various Types of Water Photography.

Simple direct exposure: close-up, scenery, modified colors, light variations, Distorted imagery and photoshopping.
Various types and forms of water; clear domestic use, natural water bodies, oceans, frozen and ice formations, flood,
rain/sleet/hail, steam and vapor, contaminated and dirty.
Changing water to produce effects; electricity and sound.
High speed exposures and magnification.
Using water as a backdrop or setting to complement a subject.
Etc.
