Technical GlossaryTask 1

Pixels are small dots on the screen that makes the image appear. The resolution show how many pixels by how many. The higher the resolution is, the more detailed the image is. As you can see in my example I have found the first box shows the resolution of 1 by 1 pixel making just one big pixel but as the resolution doubles the letter R is forming at 100 by 100 you can see the letter as clear as it was.

PIXEL AND RESOLUTION

Vector graphics are made with points, lines, curves and shapes. All of them join up to produce images in computer graphics.

Raster graphic or an bitmap has rectangle grid of coloured pixels.

VECTOR AND RASTER IMAGES

Jpg is mostly used in cameras or other capture devices. JPEG reaches 10:1 compression with little perceptible loss in image quality

Psd is an Adobe Photoshop document. The file saves I the images changes or add-ons like layers, text, transparency. Psd can hold up to 30,000 and the size of 3 gb.

FILE FORMATS AND USES

Lossless compression enables you to compress data from keeping all of the data together. When compressed all of the data is kept. This is done through mathematical formiler such as vectors.

Lossy compression takes some of the compressed data and gets rid of it, it tries to use the less amount of that that it can. A example of this is Jpeg.

COMPRESSION

Image capture devices (Cameras) take pictures or images. The device will capture what it see and save it as an jpeg. Saving it as a jpeg makes the images from the device have less quality but more file space to take more images.

IMAGE CAPTURE DEVICES

Optimising is use to get rid of unwanted files which helps speed up the computer. This would also make more room for files that seem necessary for your computer.

OPTIMISING

Storage management handles the memory within your files and hold spaces for future files to come.

Asset management takes tasks and discussions about an topic for example ingestion, annotation, cataloguing, storage, retrieval and distribution of digital assets
