Present Images appropriately
You have been approached by a music video producer. He represents a well known artist. He requires backdrops for their upcoming music video.
They are interested in the natural beauty of your surrounding area.
A portfolio of at least 10 images to choose from is required.
Care should be given to ensure all images meet the technical requirements for a 1080p video output.
JPEG ( Joint Photographic Experts Group ) .jpg .jpeg
Millions of colours, no transparency, lossy compression, can set level of compression.
PNG ( Portable Network Graphics ) .png
Millions of colours, transparency, lossless compression
GIF ( Graphics Interchange Format ) .gif
256 Colours, dithering, transparency, animation
Uncompressed Image, Large Files
RAW Image file .cr2 .nef
All of the information recorded by the image sensor in a digital camera, Large Files
SVG ( Scalable Vector Graphics )
Vector Graphics Format, Shapes, Paths, Co-ordinates, Great for Logos, Bad for Photos
Resolution is the number of pixels recorded in the image.
DPI ( Dots per inch ) defines the image detail in print
PPI ( Pixel per inch ) define the image detail on a screen
Colour Depth describes the number of available colours in an image. Colour banding is a result of a low colour depth.
Smart use of dithering can be used to improve the perception of colour.
Raster Image formats record data in a grid.
A 1-bit bitmap can be visualized as below.
After brief header information ( which will describe how wide and how high the image is ) this image could be written as;
Vector Image formats record co-ordinates, shapes, fill colours and curves.
<circle cx="50" cy="50" r="40" stroke="black" stroke-width="3" fill="red"/>
In this example we describe a circle, it’s position, it’s radius, the outlines, it’s width and, it’s fill colour.
Adhering to copyright law is essential at all times when working with images.
Consequences of ignoring copyright includes fines and imprisonment.
If you take the photograph yourself then you will own the image and can sell and licence it.
