Raster and Vector images...

Raster graphics are made from pixels and Vector images are made out of paths.
A raster image is a graphic image, as in JPG, PDF or GIF, it has specific dimensions, measured in Pixels for instance 454 x 340 pixels is photoshops default preset. If you were to make a raster image larger, the image would become 'blocky' (much as if it were made out of lego, there would be no round edges) this is because the set number of pixels doesn't change, you just make them bigger.
Vector images can be changed in size very easily, this is because they arn't using pixels, the quality would stay the same whatever size you made it.
Digital photographes are normally raster images where as computor graphics are normally vector images,k this is so that logo's made on a computer can be made any size.

Skills Profile

I have been using photoshop for about 2 or 3 years already, sao i know a fair bit of it, however, after sitting a lecture and a basic tutorial, i have realized that i have picked up some bad habbits, for exemple i haven't been creating groups to put my layers in etc. Harry also tought me how about the rule of thirds, something that i had been ignoring in all previous photoshop work.
I make films in my spare time, as a hobby and for practice, but, in photoshop i make posters for them and logos for the productions company. So I have experience in photoshop.
Here are some exemples of posters and logos i've made in photoshop

17/09/10 Film name logo

In this session i have been creating the logo of the film name 'La Cosa Nostra' for my film poster, I have been doing this to create an individual look to my poster, here is it's first draft:

The logo is for a Mafia/mobster genre of film, hence the colours red, black and white

Target Audiences

After a lecture on target audiences and taking a glance at a few adverts we have been able to, fairly basically, figure out the age, gender, social class etc of a target audience.
To give an example, the H&M advert we looked at (which unfortunately has now been deleted from youtube due to a copyright disclaim) was targeted at a female target audience with an age-range of 15 to 30 years old, due to it's artistic and 'cooky' style, the simplistic art of the advert shows that the target audience should have a higher level of education which indicates that the social class should be both lower middle and middle classes.
