Photography – Camera Modes

My featured photograph today is of the top of my camera. Like most dedicated cameras – and some smartphones – there are a multitude of dials, levers and buttons. These vary so much from camera to camera that I’m not even going to try to explain all of them. One dial, however, has settings that are common to most cameras – that is the Mode dial. In the photo, it’s the one on the left. The markings that I’ll be covering in my Blog today are those with the following marks on the dial – AUTO, P, SV, TV, AV, TAV, M, B and X.

AUTO Scene analyse Automatic exposure – the camera’s software analyses the scene and chooses for you the optimal settings.

P Programme Mode, Automatic exposure – allows you to change the ISO and exposure compensation only. (On my camera you can also set one the dials to change aperture and shutter value)

SV Sensitivity Priority Mode– Automatic exposure is similar to the Program mode but you cannot customise buttons for aperture and shutter values.

TV Shutter Priority Mode – Automatic exposure. You can change your shutter speed, ISO and exposure compensation but not your aperture setting.

TAV Shutter and Aperture Priority Mode – Automatic exposure. You can change shutter speed and aperture settings together with exposure compensation but not your ISO

M Manual Mode – You can change all the above settings. This is not an automatic mode – ie the camera does not make allowances – it uses your settings and doesn’t try to change settings to give you a good exposure. You’ve input your choice of settings, if the resulting exposure is rubbish, use the exposure triangle to get it right next time.

B Bulb exposure -You would normally use this for exposures longer than 30 seconds. You have to set the time to close the shutter by an intervalometer or a timer. you can only change the Aperture value and the ISO.

X Flash X-sync speed. – You can only change Aperture value, ISO and exposure compensation. You can change the Flash sync speed by using your camera’s Menu.

On my camera, the Shutter Speed and Aperture settings are set by rotating the appropriate wheel.
