Task 1 technical glossary
- 1. Task 1
- 2. 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.
- 3. 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.
- 4. 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.
- 5. 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.
- 6. 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.
- 7. 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.
- 8. 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, catal oguing, storage, retrieval and distribution of digital assets
