The Nature of Graphics Creation
Web optimization, source images and more
The images used on Websites have been 'Web optimized'. They are designed specifically to transfer quickly/effectively
over the Internet. This is accomplished by strategic compromises in the quality of the image. When everything is done,
the Web optimized image will appear just fine on a Website, however it really has no other usefull application.
Most often Web optimized images are created from a parent image we refer to as a 'source' ('master' is also used at times). Sometimes, there may be no
source image at all. If one is used, it may or may not be...
- 'print-ready' - Print-ready images are of much higher quality than a Web-optimized image. Web-optimized images use a
resolution of 72dpi (dots per inch) while print-ready images use a resolution of 300-600dpi (minimum).
- 'compressed' - Compression involves limiting the number of colors used in an image, and other 'corner-cutting' techniques to
bring the file size down so that the images can be quickly delivered over the Web.
- 'layered' - A layered image is composed of many 'sub-images', which together create the final image. Imagine superimposing
the absent uncle over the family photo and you get the idea. These images can then have 'sub-images' added, altered or
deleted.
It has happened that clients have asked for source images used in creating their site so they or a third party could use
them to make new versions for the Web, or maybe use them in print. As we've already indicated, there may not even be any
source images.
If you, as a client, know that you would like source images for future use, we must know of this in advance. Additionally,
it's important to note that any source files we create are not purchased as part of a Website development contract, except
where explicitly noted. Any sources we create only exist as a means to achieve our goal of creating a finished Website
for the client. Once the Website is completed and delivered the masters remain our creation and property.
We can sell these images separately, if desired, but if this intention/desire is not expressed up front, there is no way
of predicting what source images may be available.
