Camera Parts and Functions An overview of digital camera technology

Bellwork Write down five parts of the camera you think are necessary for taking good pictures. Be prepared to share these in class.

Types of Digital Cameras 3 Main classifications - Point and Shoot - Prosumer* - Digital SLR Types of Digital Cameras 2006-06-01

Point & Shoot Digital Cameras (P&S)‏ - small, compact and lightweight - inexpensive - user-friendly - 90% of all digital cameras on the market 2006-06-01

Prosumer Digital Cameras Semi-Professional Digital Cameras - similar in size to Digital Single Lens Reflex Cameras (DSLRs) - extended zoom range -user friendly AND has advanced manual features 2006-06-01

Digital SLR (DSLR)‏ SLR (Single Lens Reflex) Cameras - larger sensors - greater image quality - manual controls - larger and heavier - interchangeable system lenses - more expensive 2006-06-01

So What is the REAL difference between a digital SLR and a point & shoot camera? 2006-06-01

The short answer is.....Image Quality Because the size of the sensor matters 2006-06-01

How the digital sensor works - Each digital image is made from millions of tiny squares, known as pixel - Essentially, an image is recorded by tiny micro lenses (pixels) which make up the camera’s sensor 2006-06-01

Movement Compensation Refers to the camera’s ability to correct small movements by the user while taking a photograph, in order to reduce the blur caused by camera shake. Very useful in low-light or telephoto situations

Movement Compensation Represented differently by companies: Nikon – VR – Vibration Reduction Canon – IS – Image Stabilization Pentax – SR – Shake Reduction Sony – SSS – Super Steady-Shot

Dust Reduction Dust is more of a problem in DSLRs due to changing lenses. Once dust gets on your sensor, it can be difficult to remove. Dust reduction is essentially a mechanism which shakes the camera’s sensor to free any clinging dust particles. Special anti-static coatings or filters may also be used.

Also, the tripod socket is located at the camera base.

There are three factors that influence the exposure of your image: Shutter Speed Aperture ISO A “correct” or “good” exposure occurs when you maintain as much detail as possible in both the very bright parts (highlights) as well as the very dark parts (shadows) of an image. How much of a range in which you can capture detail from light to dark is referred to as the Dynamic Range. As you are about to see, there can be many “correct” or “good” exposures.

Write down possible solutions under your question. Closure: Parking Lot Write what questions or concerns you have about today’s lesson below. You must write at least one question. Next, go around to at least THREE other students and discuss what questions they have along with your own. Write down possible solutions under your question.

Questions to Answer What are the 3 main classifications of camera? What are some advantages of each? What is the difference between SLR and point and shoot? Define pixel. What is movement compensation? Why is dust a problem? What are three factors that influence the exposure of an image? A correct exposure occurs when.....
