M3 What impact of resolution and colour depth have on file size and image quality.

The three iamges which are shown above show that when you adjust the photo colours and image size to much, you can lose the photo quality. When the image is made too big or too small then it starts to become pixalated and the quality of that image is lost. Again the same for the colour quality if it is changed too much the biggest effect is not the colour but the quality of the image. So therefore when you are editing images you need to be careful not to manipulate the image to much as the quality of the image is at state. This post goes with my post on file extentions done on Thursday, 8 May 2008.

Explain potential legal implications of using and editing graphical images P6

Copyright

Copyright is where somebody has the right to the copy of the creation, normally for a limited time only. Copyright is a law and therefore is illegal to be broken, however you are able to copy an image as long as credited is given to the creater and you are not using it for money. You can only copyright an physical creation and not an idea.

Identifying ownership

Identifying ownership helps you find out whether or not a graphic can be reused. Images sometimes have the name of the owner or who the image is copyright too on the image or close to. However sometimes there is no name printed on the image so normaly the image will the belong to the publisher or website.

Gaining Permissions

To gain permission to the image you need to contact the copyright owner and ask permission for the image, usually if you are using the image to make money, a percentage of that money needs to go to the copyright owner.

Copyright Fee

Copyright free images can used by anyone. For example www.freeimages.co.uk/
