Week 10 - Video and Audio Practice

Week 10 Video Submission:

Using the original video files and music files:

• Cut the selected video files to size and for 1 min deadline, arranging them so that there was a flow to the video.

• Applied a crop effect and did some colourisation effects for a more cinematic effect.

• I applied a fade transition to the start and end of the video, also adding in fade transitions to selected clips.

• For the audio i added a reverb effect with a fade transition at the beginning and end. 

Week 9 - Image Processing

An image capture system contains a lens and a detector. In digital photography the detector is often a charge coupled device (CCD), a linear or matrix array of photosensitive electronic elements.

Pixelization can be seen with the unaided eye if the sensor array is too low. Increasing the number of cells in the sensor array, increases the resolution of the image captured.

Before the light is collected by the lens is focuses on to the sensor array, it is passed through an optical low pass filter that serves to:

• Exclude any picture data, which is beyond the sensor's resolution.

• Compensate for false colouration 

• Reduce infrared and other non-visible light. 

A pixel is the smallest digital element manipulated by image processing software.

Each pixel is individually coloured but since they are of finite size, pixel only approximate the actual colouring of a subject. Thus bit maps often show blocky areas or jagged lines under close examination.



Four common categorisation of DIP operations are analysis, manipulation, enhancement and transformation.

• Analysis operations provide information on photometric features of an image e.g. colour count, histogram

• Manipulation operations change the content of an image e.g. flood fill, crop

• Enhancement operation attempt to improve the quality of an image in some sense e.g. heighten contrast, edge enhancement 

• Transformation operations alter the image geometry e.g. rotate, skew

Week 7 - Looking at Light

The light generated, transmitted and reflected by objects enables us to see, record and interpret the world around us as images, capturing: colours, shapes, details and textures.

The position of the sun throughout the day is the factor with the greatest impact on natural lighting, and has the power to transform the appearance of any subject. 

The direction from which light strikes the subject is important. Subjects can be illuminated by; front lighting, side lighting and back lighting. 

Front lighting occurs when the source is behind the observer directly on to the subject. Light covers the subject evenly revealing the detail. 

Side lighting creates strong shadows, which emphasize texture in an image, giving a greater sense of shape, dimension and depth. 

The most dramatic arrangements of light and shadow appear with back-lighting. In this case, the source of light is behind the subject, creating silhouettes and other interesting effects.
