Knowing Your Camera4Digital Cameras can be seem like a complex piece of equipment. Knowing some of the basics of your camera will help you choose the right camera and produce quality photos.What is a Digital Camera A camera that takes video or still photographs (or both) digitally by recording images on a light-sensitive sensor.Ultra Compact Digital CameraTypically a small and inexpensive camera.Can easily be carried in a pocket or purse. Usually have fewer features than the higher end cameras.8

Oh the Technology!D-SLR (single-lens reflex), Megapixels, Image Stabilization (IS & VR), Dust Reduction, Live View, Sensors, facial recognition..........

What does it all mean? (and why does it matter to me?)Introduction to Digital CamerasDSLR CameraTop of the line camera; primarily used by professionals.Include high quality lenses, and often interchangeable.Often accepts other accessories such as filters.Produce very high resolution photos.55Digital Photos OverviewDigital Photos are made up of pixels (picture elements).DPI vs PPIDPI - Dots Per Inch (How a printer prints the image)PPI Pixels Per Inch (How a monitor displays an image)The resolution of a digital photo is its pixel dimensions.Digital Cameras use megapixels to specify the pixel dimensions of its photos.

2006-06-01Point and Shoot digital Cameras (P&S)- Commonly referred to as consumer digital cameras.

- Represent probably 90% of all digital cameras on the market

- Typically small, compact and lightweight

- Targeted at broad majority

- Typically very User-Friendly

- Image Quality has improved drastically

Compact Digital CamerasThe typical digital camera used for taking most pictures by consumers. Includes most of the features the average person would need.


2006-06-01Prosumer Digital Cameras-Not technically its own specification

- Common term used to describe advanced models of P&S(now also used to describe many entry level DSLR's)- Similar in shape and appearance to Digital SLR's- Typically have extended zoom range (8-12X Optical Equiv)

- Typically combine user friendly P&S features with more advanced manual features.

Advanced Digital CameraDesigned for the more skilled or hobbyist photographer.Usually has higher quality lens and zoom.


2006-06-01Digital SLR (DSLR)SLR Stands for Single Lens Reflex

- Have larger sensors, resulting in greater image quality

- Tend to favor manual control, lacking many automatic settings found on P&S

- Much larger and heavier

- Ability to interchange system lenses

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

2006-06-01The short answer is.....Image QualityBut Why?

How can a 6 megapixel DSLR take a better picture than a 24 megapixel point and shoot?

Because Size Matters!

2006-06-01How the digital sensor works- Each digital image is made from millions of tiny squares, known as pixels.

- Essentially, an image is recorded by tiny microlenses (pixels) which make up the cameras sensor


2006-06-01All Pixels are not created equal!

-A digital sensor is essentially made up of millions of tiny micro-lenses (pixels)

- Pixels are analog devices which record light and color data

- Larger Sensors contain larger pixels, which are much better and collecting this data

Digital Sensors Compared

Full-Frame versus APS-C Sized Sensors

2006-06-01Digital Camera Features and Technologies Megapixels Determine the total size (Dimensions) of the image recorded by camera

- More MP does not always mean a better picture

- Digital Image dimensions do not equal print dimensions

- For example a full quality image from an 8 megapixel camera will produce a digital image measuring approximately 9X14 inches but printing standards say that you should not print to Photo Quality any larger than 8X10

Multiplying the pixel dimension will give you the exact megapixel rating. The rating stated by the manufacturer is usually rounded.

Anatomy of a Camera

Anatomy of a Camera


Electronic ViewfinderAn electronic viewfinder, or EVF, is a viewfinder in which the image captured by the lens is projected electronically onto a miniature display. The viewfinder shows exactly what the lens sees.46

46Optical ViewfinderA window on the back of the camera you look through to position the shot.The primary drawback to the optical viewfinder is the parallax, displacement or difference in the apparent position of an object viewed along two different lines of sight.47


Unlike with compact cameras, where you compose your shots by looking at the back of the camera (LCD screen), on the DSLR, youll usually look through the eyepiece of the viewfinder for composing, focusing, and viewing certain information provided by the camera. Some DSLRs will allow you to use their LCD monitors the same way you would with a compact camera, but you wont usually take photos this way.LCD Monitor

One of the biggest advantages of your DSLR is its ability to preview an image immediately after you take a picture. The LCD monitor is located on the back of the camera and may have a swivel capability so that you can orient the screen for easier view from different camera positions. As you take each shot, a preview of the image will appear for a short time on the LCD. This monitor also gives you access to image data and the cameras menu system.LCD/OSD

An on-screen display (OSD) is information about the cameras settings displayed on the LCD screen.

Live ViewRefers to the ability to use the lcd screen on the camera the same way you would use the viewfinderShots can be composed even while holding the camera away from your faceOriginally only a feature in P&S, DSLRs now use Live View also

Facial RecognitionCamera detects faces in your frame based on color, contrast change, etc.Focus is automatically adjusted so detail in faces is highColor and contrast are automatically adjusted to create pleasing skin tones

Camera BagPurchasing a cool, sophisticated, cutting-edge camera is one thing. Getting a camera bag to support, hold and protect your camera is another. Welcome to Flipkart's mind-boggling array of camera bags that will not only satiate your requirements, but will also effectively give you the benefit of heading out with confidence on your outdoor ventures with the camera of your choice, securely by your side.Camera bags are the perfect accessories for photography enthusiasts and professionals who require one bag that carries all of their camera-based essentials. Before investing in a camera bag, ensure that the bag is able to accommodate your camera model and make sure that the bag is waterproof with plenty of internal pockets to store extra additions safely and securely. Additions such as batteries, backup lenses, charger units, SD cards, pocket tripods and many such accessories should be accommodated without a fuss.Camera bags are divided into multiple types such as holster, the belt pack, shoulder bag with one strap, backpacks, slings and so on. Choose a type or a model that is most convenient to you

Movement CompensationRefers to the cameras ability to correct small movements by the user while taking a picture, in order to reduce the blur caused by camera shake.

Very Useful in low-light or telephoto situations

Movement Compensation

Represented differently by different companies:

Nikon VR Vibration ReductionCanon IS Image StabilizationSony SSS Super Steady-Shot

Dust ReductionDust is more of a problem in DSLR's due to changing lensesOnce dust gets on your sensor, it can be difficult to removeDust reduction is essentially a mechanism which shakes the cameras sensor to free any clinging dust particlesSpecial anti-static coatings or filters may also be used

File FormatRefers to the way the computer stores the dataMore common formats include:JPEGEXIFTIFFRAWJPEGStands for Joint Photography Experts GroupMost widely used formatBiggest advantage - can compress image dataDo not edit JPEG images in photo-editing programs to minimize data lossEXIFStands for Exchange Image File FormatUsed by many digicamsIs a variation of the JPEG formatStores extra data as met
