Principle difference is "through-the-lens" framing and focus. Naturally you can control depth of field, light levels, focus, etc with both units, but with the SLR you see these changes before you take the picture. There are advantages and disadvantages to both types of camera: The compact will be smaller, lighter and quieter; the SLR has a mirror that flips up when the shutter is released to switch light from the viewfinder to the sensor. This makes a noise, the compact doesn't need the mirror so they can be pretty much silent. On the other hand, apart from the Leica M8, compact digitals do not have interchangeable lenses. Being able to change lenses is a big advantage, you can also see the affects of any filters by looking through the viewfinder. In most cases a digital SLR will have better quality optics, sensor and light metering than a compact digital - although there are exceptions; the M8 would give any DSLR a run for its money for quality - but it does cost £3000 for the body alone! ---- 9-07-2006 The SENSOR ! The sensor is what holds the image you took. On most point and shoot digital cameras, the sensor is a certain size...... On a digital SLR, the sensor is BIGGER. ---- The Sensor is not only larger, but is much more sensitive .
TLR - twin lens reflex. One lens for viewing through the reflex system, the other (mounted below the viewing lens) is used to take the picture.
SLR - single lens reflex. Same lens views through the reflex system and is used to take the picture.
rangefinder has a lens to take the image, and other lenses/prisms to give a stereo view in a viewfinder, which is used to make one sharp viewing image only when the camera is in focus. A slr uses the main lense's image to autofocus correctly, or to let the operator get the sharp point by hand and eye.
DSLR - Digital Single Lens Reflex (digital image only)
SLR - Single Lens Reflex (uses film only)
No, digital SLR's are just one type of digital camera.

The structure of the leg muscle is similar to the heart muscle in their makeup. There are studies that have shown that leg muscles can be injected into the heart.
Large rockets, computer control, compact fuel.
Specification control drawing: Per MIL-STD-100, a drawing prepared for the purpose of defining and controlling screening, electrical performance characteristics, and physical configuration of purchased material. By definition, the intent of a Source Control Drawing is to purchase controlled standard parts.Source control drawing: Similar to a specification control drawing except that purchase of the specified devices from manufacturing sources other than those listed on the drawing is prohibited.
difference between feedback and control
Difference between control process and process control is that system control process is typically the large scale version of where process control is used.
cohort is frm exposure to outcome, where a group of individuals are "followed up"case control is frm outcome to exposure.

Distinguish between internal audit and internal control.
I believe that servo is motorized and solenoid is magnetically activated.
The null hypothesis is the default hypothesis. It is the hypothesis that there is no difference between the control group and the treatment group. The research hypothesis proposes that there is a significant difference between the control group and the treatment group.
