How a digital camera works
A digital camera
is used to capture images
using pixels which are
small squares of colors shown
on a computer screen.
Downloading images
A digital camera
can be used to download images
from camera to the computer
and would have to be optimized to have
be viewable on the internet.
Raw Images
RAW images
are larger and have
a bigger file size
and should be edited or
down sampled for the web
Photoshop has a feature to edit
images called “Save For Web”.
This feature optimizes images to
be used on the internet. In this feature,
you can change the size and the file type and
changes its resolution to 72.
Save For Web
Photoshop has a feature to edit
images called “Save For Web”.
This feature optimizes images to
be used on the internet. In this feature,
you can change the size and the file type and
changes its resolution to 72.
Optimized Picture
Ratio
4:3 – is the ratio
to be shown
like a regular monitor
16:9 – the ratio
shown to look like
a widescreen monitor
Best way for naming files
Files should be named with
dashes and not underscores
(-) not (_).
White spaces in files will be filled
with %20.
*&^%$#@! Are forbidden characters in
naming files and you should avoid
using slashes in file names.
Megapixels
The file size and quality
of the picture is dependent
on how much megapixels there are
An average 4:3 computer can view
an image that is 1000 pixels wide
However a camera would take a
picture that would take up 4 and a half
computer monitors and its resolution is 350.
This picture would be a high quality but it is
not suitable for a web page when it should have
a resolution of 72 and width of 1000 pixels.
