![]() Optical Viewfinders, Electronic Viewfinders (EVF), and LCD Displays Compare these details before you buy a camera. Check each camera manual to see what the manufacturer describes as its camera’s “standard” and “best” resolution. High quality images can run from 480x240 pixels to 1,024x768 pixels or more. Standard can range from 320x240 pixels to 640x480 pixels. Images can be set to standard, high quality, and beyond. All Best and Standard are not the Same!īe aware that most cameras have two or more image quality settings (or may use interchangeable memory cards for extra storage space). If you will be in the field shooting, larger cards or a camera that saves to an external disk may be the option for you. These cards are reusable but can be a bit expensive. How many shots you can store depends on the resolution and compression quality of the image and the size of the card. The cards range from 2MB to 128MB+ storage capacity. Many cameras now come with both memory card and stick slots available. Memory options are available in many different sizes, the larger the storage device the more images it can hold. There are a number of different types of storage options, memory cards, sticks, and CDs. How you will (in the studio or in the field) and what you will be shooting (still lives or race horses), will be a major factor when deciding what type of camera you purchase.Ĭonsumer and mid-range digital cameras can now store up to 100s of images at a time. If this is an important feature to you, be sure to test the camera in the store before you decide which to purchase.ĭigital cameras vary in how many images they shoot, and how they store them. The duration of these movies are dependent upon your memory card size. The quality of these movies varies greatly from camera to camera. Many of the higher-end models allow you to shoot short movies. 1/60 of a second is the lowest shutter speed for hand-held, stop-motion photography. Moving images require a faster shutter speed. The lower the f-stop setting, the better your image will be in low-light settings. Some models have adjustable f-stops (aperture settings). The higher-end models have a hot shoe for an attachable flash unit, allowing for better lighting options. Close-up lenses are also available for some models. These options allow for close-up portraits and wide-angle shots. Others have the capability to use screw mount lenses used on video cameras. Some higher-end models are just camera back and accept interchangeable lenses. Zoom amounts can be enhanced with digital zoom technology. But some can go as high as 10 times (approx. Some models have a built-in zoom lens, which is limited to an optical zoom factor of about 3 times (approx. The least expensive models have fixed settings for all controls (shutter speed, aperture, focus, etc.). The more manual control enhancements the camera has, the higher the price tag. The quality of the image depends on the quality of the lens and the sensor chips in the camera (which convert the light into a digital signal). Digital cameras work very much like film cameras.
