'''Shutter priority''' (usually denoted as '''S''' on the mode dial), also called '''time value''' (abbreviated as '''Tv'''), refers to a setting on cameras that allows the user to choose a specific [shutter speed](/source/shutter_speed) while the camera adjusts the [aperture](/source/aperture) to ensure correct [exposure](/source/Exposure_(photography)). This is different from manual mode, where the user must decide both values, [aperture priority](/source/aperture_priority) where the user picks an aperture with the camera selecting the shutter speed to match, or [program mode](/source/program_mode) where the camera selects both.

==Background==
Shutter priority with longer exposures is chosen to create an impression of motion. For example, a waterfall will appear blurred and fuzzy. If the camera is panned with a moving subject, the background will appear blurred. When photographing sports or high-speed phenomena, shutter priority with short exposures can ensure that the motion is effectively ''frozen'' in the resulting image.

Like aperture priority, this mode allows for partial automation thus decreasing the need for total concentration.

Shutter priority is often abbreviated as ''S'' (with Nikon, Minolta, Konica Minolta, Sony, Olympus, Sigma, Panasonic) or ''Tv'' (for "time value" with Canon, Pentax, Leica{{citation needed|date=April 2015}}) on a camera [mode dial](/source/mode_dial).<ref>{{cite web|url=http://dougkerr.net/Pumpkin/articles/APEX.pdf|title=APEX—The Additive System of Photographic Exposure|last=Kerr|first=Douglas A.|date=4 August 2007|website=dougkerr.net|access-date=13 March 2020}}</ref>
