camera functions
- 2. Auto and manual camera image
- 3. Manual mode Using Manual mode is a lot easier with a digital camera than it previously was with film, because you can see immediately if the settings aren't working. You can control all a camera's settings, but only Manual mode lets you adjust aperture and shutter speed independently. • When you photograph the same thing under the same conditions, over and over again. • When you're photographing under unchanging lighting. • When the lighting is changing radically. • When the metering system delivers unexpected exposures. • When shooting video. The best times to start out withThe best times to start out with Manual mode are:Manual mode are: How to use itHow to use it •Turn the mode dial to the big "M". It is seen that using manual mode s a lot harder than using automatic.
- 4. Automatic A camera where either the lens aperture or the shutter speed or both are automatically modified to the prevailing conditions/surroundings. Is usually located on a dial on the top of the camera
- 6. View finder (screen) – In photography, a viewfinder is what the photographer looks through to combine, and in many cases, to focus the picture. Most viewfinders are separate, and suffer parallax, while the single-lens reflex camera lets the viewfinder use the main optical system. The little rectangle on top of your camera. It helps take sharper images. Looking through the viewfinder will help you stabilize the camera better also it helps take sharper images.
- 7. Lens (function, types) – A camera lens (which can also be known as photographic lens or photographic objective) is an visual lens used in combination with a camera body and device to make images of objects either on photographic film or on other media capable of storing an image chemically or electronically. There are many different types of camera lenses choosing the right one could be difficult if you don’t know much about cameras
- 8. Image sensor – An image sensor is a solid-state device, the part of the camera's hardware that catches light and changes what you see LCD monitor into an image through a viewfinder.
- 9. Aperture – A large aperture lets in more light to the camera shutter for an exposure, while small aperture has a smaller opening in the lens diaphragm to let in a smaller amount of light for a given exposure. Large (f/2.0, f/2.8 etc.) Small (f/11, f/16, f/22 etc.)
- 10. Memory (memory card, internal storage)
- 11. File storage
- 12. JpegRaw For example a four gigabyte card in an eight mega-pixel camera can hold over 400 photos if you’re shooting raw and hundreds more if you only save as JPEG. JPEG is a format for compressing image files making it a lot easier to keep and find things. JPEG format is great for storing digital photos. May reduce the file size of a image by ten times. Suitable for full-colour realistic images with a lot of colour and contrast transitions. JPEG stands for "Joint Photographic Experts Group." Advantages DisadvantagesDisadvantages Advantages the lossy compression (reducing the size of a computer file)can cause an issue called "artifacting," where the parts of the image become visibly blocky. JPEG format is not the best choice for saving images that are non- rectangular. Image might “fall apart” into separate squares. Every next step of compressing the image degrades its quality . Picture quality is high with small degree of compression. Raw stands for RAW is a file format that captures all image data recorded by the sensor when you take a photo. No information is compressed with RAW therefore you are then able to produce higher quality images. With RAW you can also correct problems with images that you could not recover if you was to shoot it in the JPEG format. You can get the Highest Level of quality by using RAW. You can also record greater levels of brightness. By using RAW you can enjoy non-destructive editing.
