Exposure Control
Exposure control of your film is probably the single most important aspect of photography to develop (no pun intended). The reason for this is really quite simple: you can't make great prints from poor negatives.
EXPOSURE CONTROL. Hmmmmmmm. What the heck does that mean? For me, varying definitions might have popped to mind a few years ago. Such a term seemed unlikely to be connected with photography.......

Exposure Control
The ability to control exposure settings such as shutter speed and lens opening is critical to professional photographers.
Exposure control : Most cameras today offer at least four different exposure modes, Program mode, Aperture priority, Shutter priority (also called Time Value), and Manual mode.
Exposure control
Programmed Auto: Camera sets both shutter speed and aperture for correct exposure.
Shutter-Priority Auto: User selects shutter speed and camera sets matching lens aperture for correct exposure.
Exposure control
Describes how the shutter speed and aperture are controlled by the camera. This can be either automatic: fully automatic, programmed auto and scene program; as well as semi-automatic: ...
[edit] Exposure control
The size of the aperture and the brightness of the scene controls the amount of light that enters the camera during a period of time, and the shutter controls the length of time that the light hits the recording surface.

Exposure control and focus is automatic, but some digital camera models offer a degree of control over shutter speed, aperture, and focus. Lenses are usually not interchangeable, but some models have a wide zoom range.
The new Exposure control works on 8-bit and 16-bit images, but was introduced to work with the HDR (High Dynamic Range) 32-bit format, also new to Photoshop CS2. We'll take a look at that, next week.

If all this sounds confusing and if you feel overwhelmed, you are in good company.
Automation of exposure control in cameras began with built-in selenium meters. Shutter speed and aperture had to be selected manually according to the meter's absolute or relative measured values.
Exposure: The exposure control does just what its name implies; it controls the exposure of the converted image. However, it has an additional benefit when it comes to increasing the dynamic range.
Flashguns with TTL exposure control are more advanced as they have a direct link, via the flash lead and plug, to a sensor within the camera.
Annoyingly, none of these buttons are labeled in any fashion to indicate their exposure control functions. I see this as being a bad choice on Sigma's part.
Strobes were only manual then, as the camera manufacturers had yet to invent TTL (through-the-lens) automatic exposure control, but a serious shooter now had several brands to choose from.
Flash Modes: One of the ways that lens shutter cameras offer exposure control is through flash modes. This allows you to choose how a scene will be rendered in both daylight and dim light.
A film's sensitivity to light, rated numerically so that it can be match to the camera's exposure control. Film speed ratings increase as the sensitivity of the film increases.
Advanced photographers typically graduate to a digital SLR (DSLR) camera which provides the ultimate in exposure control and flexibility.
Shoot on full manual exposure control and use your light meter, if equipped. You are trying to purposely UNDERexpose your sunrise or sunset images. This will deepen the colors you are aiming to portray.
There exists several usable alternatives for underwater photography, like digital point and shoot cameras, compact digital cameras with full exposure controls, and SLRs (single lens reflex cameras).
For total exposure control, especially in tricky lighting situations that can fool a camera's exposure meter, choose the Manual Exposure mode.
If you want to be a digital artist then you'll need to be so comfortable using your camera that the exposure controls are second nature to you, so you can focus yourself on composing the scene that you want.
Automatic or manual exposure controls
The more you learn about photography the more freedom you want when it comes to the ability of controlling the focus, shutter and aperture manually.

For casual photographers who want to adjust contrast without fancy lighting or exposure controls there is an easy way out. Almost any digital camera available will let you preset contrast levels to high, low and everything in between.
One way to work in such situations is to manually play around with your exposure control and take a series of shots - the problem with this is that it takes time and if you are photographing a changing environment (for example a sunset which changes ...
The higher the ISO, the greater the sensitivity. ISO is one of three exposure controls on a digital camera, in addition to aperture and shutter speed selection. Each exposure control allows you to affect different image characteristics.
Again, it's a great place to start; but for better exposure control, a wide range of shutter speeds is best. You choose them by setting your camera on shutter priority mode (symbol is TV) and selecting a longer exposure.
