Camera

Manual mode

Shooting in manual mode is one of the many things you need to learn to be able to master a DSLR camera. Manuel mode is the setting where you control everything, for example if there’s a lot of light and dark things in one picture, for example while you’re on a plane.

In this picture we can see there are no effects it’s just handling the light and dark well and making it a well coloured shot. The contrasts are balanced.

This is where the manual mode button is on a DSLR camera if you don’t know.

Automatic mode

This is a mode where it decides what it needs to do to make the picture as perfect as it can be, it determines the shutter speed, white balance and ISO.

Capturing images

Viewfinder – this is a little place to look through for a better picture, if you hold it up to your eye and take the snap, what you saw in your eye is exactly how the picture comes out. http://www.wikitricks.org/what-is-viewfinder/

Most people that use this regularly for taking pictures like their pictures to be perfectly focused.

 

Lens – This uses light to make the picture mainly focused on the retina. The lens is transparent, some different types of lenses are

• Fish eye lens
• Ultra wide-angle lens
• Wide angle lens
• Standard lens
• Short telephoto lens
• Long telephoto lens

 

Image sensor - This determines how the picture comes out, it detects everything going on around in the field of whatever picture your taking.

Aperture (f-stops)

An aperture is combined with shutter speeds, the smaller the diameter of the aperture the more focused the whole picture is, whereas if the diameter is wider the more focused the camera will be on whatever you choose. An example of what I’m trying to say is in the picture above this text.

Shutter

On all cameras there’s a shutter release button, this is just the main button on the camera, once pressed a picture will be taken

 

Memory  (Memory card, internal storage)

This is a little sim card, where you can save all the images or videos you take. Memory cards don’t require power and can be used in mobile phones

Lighting

Flash – flash is when a sharp beam of bright light which comes out of your picture taking device to show a picture as well as it would be in the daytime.

Exposure

Over exposure is when there is too much light in the picture making the picture too pale or washed out. Under exposure is where too little light is caught and it makes the picture look dark/not clear.

Colour

Colour temperature is where light is given off from an object in the background of the picture, so for example the flame from a candle is going to be the hottest temperature in the picture. Warm and cold colours all depend on where the pictures being taken, what time it’s being taken at and the lighting being used.

White Balance

This is where unrealistic colours are removed from the picture, white balance is usually neutral during the day time.

Lights

• Tungsten – these lights are regularly used in the studio for good lighting in the studio, Most of our lighting at home is in fact tungsten
• Fluorescent – this is another word for a very colourful/brightly coloured light.
• Natural – This is just Mother Nature’s light, such as the sun or reflections etc.
• Artificial light – these kind of lights are used to create effect, this lighting can also be called illumination, this involves things such as lamps etc.

Support

• Hand held – this is where a film or clip is shown from a first person perspective, for example in the movie chronicle; the whole movie is filmed by someone holding the camera.
• Tripod – A three legged stand to support the camera for when you want the shot to be 100% still.

File storage

• Type – raw photo files may not be recognisable to cloud drive as photo file.
• Type – jpeg is one of the most popular methods used for digital images, this compresses the file. It’s an image format.
