  • Canon PowerShot G12, Selecting a White Balance

    This probably seems like a no-brainer. If it’s sunny, select Day Light. If it’s overcast, choose the Cloudy setting. Those choices wouldn’t be wrong for those circumstances, but why limit yourself? Sometimes you can change the mood of the photo by selecting a white balance that doesn’t quite fit the light for the scene that…

  • Canon PowerShot G12, Selecting the Proper ISO

    When shooting most landscape scenes, the ISO is the one factor that should only be changed as a last resort. While it is easy to select a higher ISO to get a smaller aperture, the noise that it can introduce into your images can be quite harmful (Figure 7.2). The noise is not only visible…

  • Canon PowerShot G12, Sharp and In Focus: Using Tripods

    Throughout the previous chapters we have concentrated on using the camera to create great images. We will continue that trend in this chapter, but there is one additional piece of equipment that is crucial in the world of landscape shooting: the tripod. A tripod is critical for a couple of reasons. The first relates to…

  • Making Games for Windows Phone 7

    Getting Started with Windows Phone 7 There are two ways we can develop games for Windows Phone 7: Silverlight and XNA Game Studio. Although Silverlight does have basic graphics capabilities, those capabilities are provided to support applications and are not ideally suited for games. XNA, on the other hand, was developed specifically for game development!…

  • Canon EOS 60D, A Few Words about External Flash

    As you’ve learned in this chapter, the built-in pop-up flash on the 60D is a nice addition to the camera, and it can be useful, but as far as quality of light goes, it’s average. I don’t use this flash very frequently in my photography, since I find that there are other, more flattering ways…

  • Canon EOS 60D, 2nd Curtain Sync

    The 60D has two flash synchronization modes: first curtain and second curtain. The term curtain relates to the opening and closing of the shutter—the first curtain refers to when the shutter is being opened, and the second curtain describes the point just before the shutter is closed (try to visualize a curtain on a stage…

  • Canon EOS 60D, Reducing Red-Eye

    When photographing people with an on-camera flash, one thing that we’ve all seen and would like to avoid is red-eye. This effect is the result of the light from the flash entering the pupil and then reflecting back as an eerie red glow. This is especially true when it’s dark and the subject’s eyes are…

  • Canon EOS 60D, Compensating for the Flash Exposure

    Sometimes your flash will be too bright or too dark for your subject. While the E-TTL system is highly advanced and will get the flash’s output close to where it should be, it doesn’t always know what you want the image to look like. Like exposure compensation, flash compensation allows you to dial in a…

  • Canon EOS 60D, Using the Built-in Flash

    There are going to be times when you have to turn to your camera’s built-in flash to get the shot. The pop-up flash on the 60D is not extremely powerful, but with the camera’s advanced metering system, it does a pretty good job of lighting up the night… or just filling in the shadows. The…
