Basics of Digital Photography
SAY HI to Deepaul
DSLR Camera : Canon Rebel XS , Lens Pack : Canon 17mm – 85mm EFS f4 - 5.6, 75mm – 300mm EF f 4-5.6 , 50mm f 1.8 Prime Lens, Tripod
Through my photographs, I share my love for nature, travel, friends and people. I got my first digital camera in the year 2004 and it took long 6 years to own a DSLR. I started capturing the life within the image. My preference is to shoot in natural light, and an eclectic range of images always provoke the shutter finger.
Understanding Basic Equipment and Recommended gear
Digital Photography GearCAMERAS Point & Shoot / DSLR / Mobile You do your research, and you can spend
much less than expected and still get a camera which produce good results.
LENS PACK / Filters
Standard / Wide/ Zoom /Telephoto / Prime/ Fisheye Lens may come with or without Anti-Blur
TRI-PODS,CARRY CASES,MEMORY CARD* All other equipment and accessories are optional.
Price isn’t the best indicator.
The Do-it-all SettingPhotography Modes
AUTO MODEAll digital cameras usually have an Auto mode, the camera decides for you the best shutter speed/aperture settings.
SPORTS MODESports/Action Photography tells the camera to default its settings toward capturing images faster .This is done by: Increasing Shutter Speed, Increasing ISO
POTRAIT MODEThis mode is not well suited for full-length portraits or groups of people Portrait mode tells the camera to default to a: •Small Depth of Field (Large Aperture)– f1.8
NIGHT MODEThis preset slows down the shutter speed to allow a lot of light into the camera. Both the foreground and background of the image are properly exposed.
LANDSCAPE MODEPrimary function is to allow a large depth of field. Landscape mode tells the camera to default to a large Depth of Field (Small Aperture)–f16.
MACRO MODEThis setting works with your camera lens to allow it to focus from a very short distance. Depth of Field becomes very Small (Large Aperture)– f1.8 •Does not have a lot of alternative uses.

EXIF [ Exchangeable Image File ]
Data stores information like camera model, exposure, aperture, ISO, what camera mode was used .....
To interpret this EXIF data, you will need an EXIF viewer. Your image processing program should provide that functionality within the program.
For beginners, reading an images EXIF data can be a very useful learning tool.
HISTOGRAMThe image below shows two unprocessed shots taken within seconds of one another, with their associated histograms. The shot on the left is underexposed and the shot on the right is exposed so that the histogram is pushed up to the right hand side, as far as practically possible wihout losing any highlight detail.
Balanced HistogramA more balance Histogram depicts a graph with the pixel representations spread across the graph and tapering off on both ends, such as in this image.
Over exposed ImageMany images we capture might tend to be over or under-exposed. It’s easy to tell when a shot is way overexposed because most of the detail in the image in blown out. In scenic images, a loss of detail often occurs with clouds and the sky in the background, such as with photo below.
Under exposed Image When the Histogram is bunched up toward the left (pure black), it indicates that areas of the photo are underexposed, and that details are clipped in dark and shadow areas.
WHITE BALANCE:• The ability to adjust colours based on white as a reference colour to
give as true a white as possible • All other colours are corrected accordingly • Auto WB (AWB): the camera determines and selects the correct
colour temperature for white.
METERING: How the camera measures the amount of light available to expose a picture • Centre-Weighted: Readings are taken at various part of the picture,
with a special emphasis for the centre. • Spot: Readings are taken at a specific point.• Each camera manufacturer has its own variations (Evaluative
Setting and Using Your Cameraon Manual Mode
The Three-Step Process to Shooting in Manual ModeSTEP 1: Set the appropriate White Balance
STEP 2: Set the desired ISO
STEP 3: Set Shutter Speed OR Aperture – Which is MORE important?i. set desired shutter speed ( 1/250)ii. set desired aperture UNTIL exposure level indicator levels off at zero.( In the image its + 1)iii. Adjust the value to bring EV to zero
Remember the fun you had as a child, just playing with your friends, not a care in the world and wide eyed at every new discovery?
Well, it’s time to do it again if you love photography, though hopefully without grazing your knee or ruining your favorite shirt!
You are smarter than your camera. That’s it. That’s all you need to believe in yourself.

Shooting Techniques On any camera
PHOTOGRAPHY TECHNIQUESLighting and ExposureNothing can ruin a good photo more than lighting. A photo with too much or too little lighting can interfere with the exposure process and then produce a photo too dark or do bright. So always choose the proper setting for exposure and always properly light your subject.
FocusBlur or clarity. Your pick. Most of the times clarity wins over blurriness. Focusing is something they you will have to toy around with, changing your distance away from the object, or changing the zoom, can help you get in focus. When focusing an image, always use the view-finder, never wing-it. You want to have your image as clear as possible, and always try it from different angles
A photograph that make a path to follow for the viewer
PHOTOGRAPHY TECHNIQUESPositionPosition can change an image dramatically. When shooting an image, remember the following: 2/3 or 1/3, not 1/2That means that you should not place the horizon at the direct center of a photo, but instead place it at the 1/3 or 2/3 mark of the page. It looks more natural and inviting. Also, getting a short from a low or high position can create a different feel. So change your position and create a new image.
Use of your tri-podTo use your tri-pod, screw on your camera to the thread. Now locate your subject and tighten the head of the tri-pod to hold the camera in place. Adjust the height accordingly. The use of your tri-pod is simple yet it produces marvelous images. Just see for yourself
Placing the object in the frame : 1/3 for the chopper and 2/3 for the sky
PHOTOGRAPHY MYTHSMegapixel Myth : How much do you need?• Often, cameras are categorized by the number of Megapixels they
can capture . • As if that resolution figure is the only measure of the camera’s
value. • This value can be quite misleading.
For megapixels you should keep in mind the following things What you plan to do with the photos you take: 8 x 10” Photo Prints or. 20 x 30” Posters •Do most of the photos you take end up as your wallpaper on networking sites
PHOTOGRAPHY MYTHSZOOM: Optical vs. Digital Zoom• An optical zoom uses the optics (lens) of the digital camera to move
you closer to your subject.• A digital zoom simply enlarges the existing image digitally. It is not
really zoom, in the strictest definition of the term.• Enlarging the image digitally reduces picture quality, and should
therefore usually be avoided . • Some manufacturers label their lenses with the "total zoom" by
multiplying the optical with the digital. Ignore It. •When comparing digital cameras: Go for higher optical zoom. Digital zoom can always be achieved later in an image editing software.
