Easy-to-Learn Features That Improve Your Pictures
Affordable digital cameras have several easy-to-learn features that can improve the quality of your photographs, especially in photographic situations that commonly make it difficult for digital cameras to get a good reading on the lighting. Some of these situations include very bright scenes, scenes with lots of shadows, backlit people and objects, and indoor scenes with artificial lighting. Among the settings that you can change to help your camera get a better reading on the lighting are the EV or exposure value, the ISO setting, the shutter speed, the aperture or lens opening, and the white balance.
How Your Camera Takes a Light Reading
Your camera takes a light reading the same way that photographers have been taking light readings for decades. It uses a built-in light meter.
Photographers used to carry light meters with them. To take a reading, they would hold the light meter to a white object that they intended to include with their subject or that was receiving the same type of lighting as their subject. In certain lighting situations, though, digital cameras can have a problem determining what is white.
When the Picture Has Too Much White
When attempting to read the light in a very bright scene, especially when the sun glares off of snow, water, or a sandy beach, digital cameras can have difficulty determining the difference between true white and other very pale colors in the scene. Consequently, it may read them all as white.
The solutions include:
- Changing the EV Setting Even many point-and-shoots will let you change the EV setting when you are using a semi-automatic scene mode. Changing the EV setting often is referred to as lightening or darkening the image. It may seem that you would want to darken an image that contains too much white, but the real problem is that the camera has selected colors to represent white that are darker than white, even though those colors are very pale. So, in order to get the camera closer to using true white for its light meter reading, you actually need to lighten the picture by raising the exposure value by a range from +1 to +3. The camera then automatically adjusts the ISO setting, shutter speed, and aperture or lens opening to the new exposure value.
- Changing the ISO Setting Digital cameras and most point-and-shoots also will let you change the ISO setting. The numbers used for the ISO setting relate the different types of film made for film cameras and how sensitive they are to light. The lower the ISO number, the less sensitive the film is, and the less light it absorbs. The ISO settings for digital cameras also change the amount of light the camera absorbs, so, in very bright settings, you will want to lower the ISO setting. After you change the ISO setting, the camera then chooses an appropriate shutter speed and aperture setting.
- Changing the Shutter Speed and Aperture or Lens Opening Another way to adjust the camera’s light meter reading is to reduce the amount of light that enters through the camera’s lens. Point-and-shoot cameras may not allow you full manual control of these setting, but most offer shutter priority mode and aperture priority mode. Digital cameras also offer these modes, and these may be the least intimidating way of adjusting these settings. When you choose shutter priority mode, you choose how fast you want the shutter to operate, and the camera chooses the appropriate ISO setting and aperture opening to match the shutter speed. The faster the shutter operates, the less light enters the lens. When you choose aperture priority mode, you choose how large the lens opening should be, and the camera then chooses an appropriate ISO setting and shutter speed to match the size of the aperture. Again, the smaller the aperture opening, the less light enters the lens.
- Changing the White Balance for Brightly Lit Scenes Changing the white balance to adjust the camera’s settings for a brightly lit scene is easy using the camera’s white balance presets. Find the white balance setting in the camera’s menu, and set it to full sun or sunny day.
When the Picture Is Too Dark
Settings with lots of shadows or little to no light also create a situation in which digital cameras have trouble knowing what is white. In this case, the camera will choose a lighter area to use as white, but instead of white, that area might be a gray or one of the lighter colors in the scene. As you might already be guessing, the changes you need to make to the camera’s settings are the opposite of the ones suggested above. You need to enable the camera to see more of the range of dark colors by lowering the EV setting. You need to use a higher ISO setting to increase the camera’s sensitivity to light. You will need to let more light through the camera’s lens by slowing the shutter speed and choosing a wider aperture setting. When adjusting the white balance setting, choose the setting for a cloudy day or for shade. If the setting is very dark, changing only the white balance setting won’t be sufficient.
When the Colors Are Too Red or Too Blue
The white balance setting not only provides another way to adjust the camera’s settings to the amount of light in the scene but also to the type of lighting present in the setting. When you’re shooting indoors under artificial light, you may notice that the colors in an image look too red or orange or too blue. That’s because, while the camera may have chosen a true white object for its light meter reading, the artificial lighting in the room affected the way the white looked to the camera.
Incandescent lighting from tungsten lightbulbs has a yellow glow. Candlelight and firelight have an even deeper, warmer glow. The camera’s choice of what represents white under those lighting conditions is influenced by that warm red, orange, or yellow glow. The camera then adds that same amount of glow to all of the colors in the scene. The simple way to counteract the glow from incandescent lighting is to change the white balance to the setting for incandescent or tungsten lighting.
Fluorescent lighting, on the other hand, has a cool, blue glow, and again, that glow influences the way true white looks to the camera. Under fluorescent lighting, the camera adds that blue glow to all of the colors in the scene. Changing the white balance to the setting for fluorescent lighting counteracts the influence of that blue glow.
You may find yourself in a situation in which you have multiple light sources. You could have natural light from a window, incandescent light from a ceiling fixture, and fluorescent light from a desk lamp. If you want to compensate for all of these sources of light, then select custom white balance from the camera’s white balance menu. Take a plain white sheet of typing paper and place it somewhere where it receives light from all of the different sources of light. Set the camera to custom white balance, and fill the viewfinder or the display screen with the image of the piece of paper. Depress the shutter, and the camera will store that image in its white balance settings and use it for the custom white balance.
Resetting the custom white balance setting each time you use your camera provides your camera with the most accurate light reading, but if you are in a situation where you need to capture images quickly, rely on the preset white balance modes.
Adjusting the Light Meter With the Camera’s Metering Modes
Another setting that digital cameras and most point-and-shoots will let you adjust is the metering mode. These three modes – matrix, multi, or evaluative mode; center-weighted mode; and spot mode – tell the light meter which area of the image to select when taking its reading.
When the camera is set to matrix, multi, or evaluative mode, the light meter reading evaluates the light from the entire scene when it takes its reading. When you are taking a portrait of a large group, a close-up selfie, an architectural image or a photograph of an iconic landmark building, or a landscape or panorama shot, you will want everything in the scene to be clear and well-lighted. You will want to use matrix modes for these types of images.
When the camera is set to center-weighted mode, it takes a reading of the light from the background, but it gives priority to the readings it takes from the center of the image, or to the area surrounding the focus point if you are composing a shot in which the main subject is off-center. This is the mode to use for portraits and still-life photography.
Spot mode takes light readings only from the area where the camera is focused. The reading is taken directly from the subject and its immediate surroundings and is not influenced by the lighting of the background or foreground. This is the mode to use when you focus in tightly on a distant or fast moving subject. When using a telephoto lens with spot mode and focusing in tightly on your subject, keep in mind that, as your camera focuses into the right and left of your subject it also focuses into the front and back. Always check your subject to be certain that the areas closest and farthest away from the camera are in focus. If they aren’t, enlarge the aperture setting or adjust the telephoto lens to focus on a slightly wider area.
Megapixels, Photoreceptors, Image Sensor Sizes, and Image Quality
The number of megapixels does make a contribution to image quality, but it is only one factor. The size of the camera’s image sensor is another important factor.
Size matters because the image produced by a digital camera is actually captured by the photoreceptors that cover the surface of the image sensor. Each photoreceptor equals one pixel, so if you have two image sensors of the same size, then the image sensor with the most photoreceptors will be the one that captures the most details and produce the better photo. However, a larger image sensor will have larger photoreceptors.
Larger photoreceptors are important for CMOS images sensors, which is the type of image sensor found in most cameras because each photoreceptor on a CMOS image sensor has its own connection to the camera’s image processor. This connection takes up space on the image sensor, and when you have smaller photoreceptors, some parts of the image can fall on the spaces occupied by the connections instead of on a photoreceptor.
The image processors of cameras that use smaller image sensors compensate for the missing parts of the image by comparing all of the adjacent photoreceptors and filling in the space in the same way that Adobe Photoshop fills in pixels when you increase the resolution of an image beyond the resolution of the original.
By contrast, the larger photoreceptors on larger image sensors cover these connections and capture the parts of the image that fall on those parts of the image sensors. So, cameras with larger image sensors may have fewer megapixels but produce higher quality images because the larger photoreceptors capture more of the details from the actual image rather than relying on the camera’s image processor to fill in the gaps.
Our Winner for the Best Digital Camera Under 400
The choice was difficult because all of these cameras are worthy contenders. Our choice, though, is the Canon EOS Rebel T6 Digital Camera. It wins because you can pair its larger image sensor with any of Canon’s EF and EF-S lenses. So, you can purchase a zoom lens with a range comparable to the cameras above while having the larger image sensor. Because LED displays can be hard to see in bright sunlight, we like cameras like this Canon Rebel that have viewfinders. We also favor cameras that allow you to capture still images in both RAW and JPEG formats. The camera operates more quickly in JPEG, so JPEG is a good option for shooting fast action or when you are attempting to capture shots of kids, pets, wildlife, and other subjects that could move at any second or when you, yourself, are on the move while trying to capture an image. However, shooting in RAW format allows you to capture and preserve all of the color and details present in the scene. As you develop as a photographer, you will appreciate the control the Rebel T6 gives you over color temperature and the variation in moods that you can create with the ambiance settings. Finally, we are partial to cameras with built-in Wi-Fi because we like the idea of being able to stream live videos, immediately uploading photos and videos to the internet, and using a smartphone or tablet to control the camera remotely. Remote control not only eliminates almost all sources of camera shake but also allows you to film yourself at some distance from the camera and to see the image you are capturing even if the camera lacks a tilting or flip up LED display. For these reasons, we think that the Canon EOS Rebel T6 is a versatile camera that will serve you well.
