Auto and Manual Camera ImageFrom these two similar images we can tell the differences as the camera options are changed from automatic to manual. When a camera is put into automatic there is a massive difference as the colour of the image is chosen by the camera itself, on the other hand manual is all down to you and how you want the picture to come out E.G if you want more light you would manually increase it by selecting different settings on the camera. Manual lets you select the image colour you prefer, manual is down to your own preference. However automatic just does everything for you, it sets the picture most appropriate for the location. This image here is a better picture

than the auto one as it was taken on manual settings, this means that the image was slyly self edited by the photographer before taken. This was done by just manually adjusting the settings on the camera itself.

The picture taken here was taken in automatic mode and we can clearly see that the lighting is too much however we cant adjust it as its on automatic mode, to adjust the brightness we will have to retake it on manual.

DLSR Camera• You can easily adjust it from

automatic to manual from turning this mode dial here.

Smart Phone CamerasSmartphones over the years keep getting better and better, apple and other mobile device developers have also increased the camera quality and added complex settings to make the picture advanced.

This option here is to flip the camera from front to back.

This setting here is a timer, you can click on it and it will give you options (3 seconds, 5 seconds, 10 seconds) if you choose one it takes the picture when the timer ends.

HDR makes the picture taken more clearer and makes us more able to see the smallest detail.

This lighting bolt sign is for the flash, most of the time the flash is on auto. This means that the flash will be used when it needs to be used for example in a dark area it will be on, if it’s a bright clear place it will be off, however it can also be manually adjusted to on or off.

Capturing images • Viewfinder – A viewfinder in photography is what the photographer looks through to

take the picture. When using the viewfinder you can see exactly what the naked eyes see so therefore you are visible to see things that the little screen cant.

Camera lens

• A camera lens (also known as photographic lens or photographic objective) is an optical lens or assembly of lenses used in conjunction with a camera body and mechanism to make images of objects either on photographic film or on other media capable of storing an image chemically or electronically.

Image sensor• An image sensor is a solid-state

device, the part of the camera's hardware that captures light and converts what you see through a viewfinder or LCD monitor into an image. Think of the sensor as the electronic equivalent of film.

Aperture• In photography and digital

photography, aperture is the unit of measurement that defines the size of the opening in the lens that can be adjusted to control the amount of light reaching the film or digital sensor. The size of the aperture is measured in F-stop. See also shutter speed. Aperi.

shutter

• Simply put, a camera shutter is a curtain in front of the camera sensor that stays closed until the camera fires. When the camera fires, the shutter opens and fully exposes the camera sensor to the light that passes through the lens aperture

Memory

• Most SD cards you'll find today are technically SDHC, with capacities between 4GB and 32GB. The largest class is SDXC, or Secure Digital Extended Capacity, can range from 64GB to 2TB. (Currently, no cards actually get anywhere near 2TB; the largest capacity available is 128GB.)

Flash• Flash is an

additional light that is given out when the picture is taken so you can have a clearly view of the picture.

ExposureExposure is a mode/setting which determines the way the image presents it self, either light or dark when its captured.

Colour TemperatureThis setting here changes the colour of the picture due to the temperature of the surrounding

Lighting

• White balance

This is the process where you can remove the unrealistic colour cast in the image.

Support• Hand HeldHand held filming is a technique in which the camera Is being operated by the person in control.

• TripodTripods are used to hold a camera in a specific place where its unable to move or wobble.

JPEG VS Raw• When shooting in a format like

JPEG image information is compressed and lost. Because no information is compressed with RAW you're able to produce higher quality images, as well as correct problem images that would be unrecoverable if shot in the JPEG format.

SizeFile size is a measure of how much data a computer file contains or, alternately, how much storage it consumes. Typically, file size is expressed in units of measurement based on the byte. ... The maximum file size in the FAT32 file system, for example, is 4,294,967,295 bytes, which is one byte less than four gigabytes.
