1). Photography 101: Taking Sharper Photos
Yes, it's possible to sharpen images digitally post-shoot, but it's always best to get the sharpest shot up front, before your photo is even developed. It's really quite easy to improve the sharpness of your daily shots - just consider these concepts!
1) Use a Tripod, if at all possible
Tripods are by far the best method of ensuring image sharpness right in the camera.
2). Advanced Exposure and Metering
Most humans see the world in living colour, but did you know that your camera’s light meter does not? Then how does it capture photos? Does it see the world in black and white? No! When your camera left the factory, it was calibrated to see the world as neutral grey, no matter what the lighting conditions! Neutral grey is defined as an object that reflects 18% of the light rays that hit it.
3). Zoom Lens Characteristics
When you own a Single Lens Reflex (SLR) camera, you have the option of purchasing more than one lens for various purposes. This article explores some characteristics you should consider once you've decided on the type of zoom lens you plan to purchase, including Internal Focusing, Image Stabilization or Vibration Reduction, Constant vs Variable Aperture, Macro Focusing, Low-Dispersion Glass, Apochromatic Lenses, Aspherical Elements, Tripod Mounts for Long Lenses, Plastic vs Alloys, Size, Weight, and Price.
4). Photography 101: Memory Cards for Digital Cameras
What is a Memory Card?
A memory card is a storage device commonly used by digital cameras to write digital photos. It is a mechanism to store your photos, and later transfer them to computer for processing and printing. Essentially, a memory card is to a digital camera what a hard drive is to a computer. That means that the size of your memory card.
5). Photography 101: The Basics of Metering and Exposure
Typical humans see their world in 16 "f-stops", or measurements of light reflecting off their environment. Cameras “see” no more than 5 stops at once. So the more contrast there is in the scene, the more stops of light there are to BE seen. This concept means that correct exposure on your camera is critical to avoiding under- or over-exposure. To understand how a camera measures this light, let’s start with the proper definitions of Exposure and Metering.
6). Photography: Using Shutter Speed to Control Motion
Shutter Speed, simply put, controls the speed at which the camera’s lens opens and closes. It works in conjunction with film speed (a.k.a. ISO) and aperture (lens opening size) to correctly expose an image. By using the Shutter speed priority setting on your camera, you are able to control motion and capture your moving subject effectively. Let’s look at the various ways to do this.
7). Digital vs Film Photography
First, let's define film photography as any capturing and processing of images via a camera that stores its image on a film medium. Then digital photography is the capturing and processing of images via a camera that stores its image digitally on memory card. The difference between digital and film photography can now be discussed.
The largest fear that professional photographers have in switching to digital is image quality.
8). Photography 101: External vs Built-in Flash
External flashes, or accessory flashes, have several benefits over built-in, pop-up flashes seen on most cameras today. Power, the ability to change light source location relative to the lens, and additional features all make external flashes worth considering for the avid hobbyist.
Bulb Power
First, let's discuss power. Simply put, external flashes have much more power than built-in flashes.
9). Digital Photography: White Balance Demystified
The term “white balance” originates from the world of video imaging where a device (waveform monitor) was used to match or “balance” the signals from the camera’s red, green, and blue channels to make accurate whites under various lighting conditions, thus balancing your white. In this article, we’ll use “white balance” for digital cameras in a similar sense: the process of measuring your light source’s colour temperature accurately, based on your lighting conditions, and using that information to correctly balance your whites and colours.
10). Photoshop and Photoshop Elements Tips for Basic Photo Editing
These days, digital photographers want to edit their photos to crop, rotate, brighten, and otherwise tweak before printing. Below is a list of some basic tricks to speed up your editing and improve you knowledge of Photoshop and Photoshop Elements.
1) Crop Tool: Crop and Rotate your image at the same time
Cropping allows you to remove unwanted edge areas from your image, thus omitting ugly things in your photo's frame.
11). RAW vs JPEG Image Capture for Photographers
These days, almost all mid-to-high end digital cameras offer the ability to capture photos in either JPEG or RAW format. This article takes a look at the pros and cons of each to help you figure out which method is best for you.
JPEG Image Capture
How your camera captures JPEG images:
First, the camera's processor applies colour, exposure, contrast, noise reduction, white balance, and sharpness adjustments to the image based on configured settings.
12). Aperture and Depth of Field for Photographers
First, let’s review the three things that directly influence how all photos are captured on both film and digital cameras:
1) Aperture: the lens opening
2) Shutter Speed: the speed of opening and closing the shutter, which determines how long the subject matter stays on the film that comes through the given aperture
3) The speed of the film (a.k.a.
