Optimising:
Optimising images for the web is very tricky. You have to get the right balance between filesize and picture quality. Look at a webpage,  you will be able to see that most of its load time comes from images. Your website will be ridiculously slow if you don't drop the sizes of the images. There are three areas where bytes can be shaved off your graphics: bit depth (number of colours), resolution, and dimension.You don't need really expensive graphics editors to reduce the sizes of your images, there are plenty of free utilities that will do the job.

Image Capture:
Image Capture is a program from Apple that enables people to upload images from  cameras or scanners which are  connected directly to the computer or the network. It doesn't include organizational tools like iPhoto but is useful for soritng out images from different varietys.

File Formats:

File formats are the correct file types and settings recommended for creating a portfolio, you need to make sure when your printing that the resolution is set to 300 dpi (Dots per Inch) so the image does not distort. Distortion means when an image is printed and the image quality becomes all pixelated because it wasn’t set on the right resolution.

Page Templates:
There are quite a few purposes for page templates, here is why:

• Planning/Sketching - When making a page template, you need good planning to make sure everything you want fits on the page and everything looks neat and professional. Also when planning your page templates out, you will need to sketch examples of your templates to make you final decision, there is no point planning a template in marker pen as you may want to rub things out, this is exactly why sketching is a great idea.

Creating your own - When creating your page templates, you want to make sure you make it from scratch, your own ideas, you want to make sure you have originality, it wants to be unique. If you have your own page template it makes your work different from everybody elses and thats what will make your work professional and intriguing.

Skills & Capabilities - While creating this it is really important to show off your skills and also what you are capable of, the better your templates, the better your work looks and is good for what an interviewer is looking for. Its important to add your own work to it also.

 

Colour Space:

 A colour space is a method by which we can specify, create and visualize colour. We usually define a colour by its  brightness, hue and colourfulness. A computer needs the colours red, green and blue to recognize an image and also to process that information. A printing press may produce a specific colour in terms of the reflectance and
absorbance of cyan, magenta, yellow and black inks on the printing paper.


Different colour spaces are better for different applications, for example different equipment has
limited factors that dictate the size and type of colour space that can be used.

Bit Depth:
In computer graphics, colour depth or bit depth is the number of bits used to represent the colour of a  pixel in a bit mapped image or video frame, the greater the bit depth, the better the quality of stored or reproduced image. The bit depth determines or should i say demands how many colours will be displayed on an image at one time. If too many colours are shown all together at one time, the loss of the image becomes. 

4-bits 16 (Standard VGA)
 8-bits 256 (Super VGA, indexed color) 
16-bits 65,536 (High Color) 
24-bits 16,777,216 (True Color) 
32-bits 16,777,216 + alpha channel
 15-bits 32,768 (Option on some earlier display adapters)

'True color is the specification of the color of a pixel on a display screen using a 24-bit value, which allows the possibility of up to 16,777,216 possible colors. Many displays today support only an 8-bit color value, allowing up to 256 possible colors.' - from

Vector Image:
Unlike JPGs and GIFs etc. vector graphics are not made up of a grid of pixels.Vector Graphics are made up of vectors which lead through locations called control points. Vector graphics use lines, shapes, curves etc which are based upon a mathematical expression to represent images. The other way for representing graphic images is through bit maps, in which the image is composed of a pattern of dots. Vector-oriented images are a bit more flexible than bit maps because they can be re sized and/or stretched. Because vector images are not made up of a specific number of dots, they can be scaled to a larger size and also not loose any image quality. You can usually identify a vector image by looking around the edge of the image, the image around the edge will always appear much more smoother whether you have zoomed in large or small, it will stay the same. Text is also one of the most common types of vector image. No matter how much you increase a font’s size, its look never changes.

Because vector images are recognized in a mathematical sense, the image size becomes much smaller and doesn't have a lot to take on when it comes to saving, so leaves you a lot more memory and space than a raster, therefore it is much easier to transfer from one computer to the next.
