2. Typography
From a descriptive and simplistic point-of-view, typography is the
arrangement of type. But there is so much more to it than that. It can
mean different things depending on whom you ask.
For me, how typography is used in a design is deeply rooted in its
overall theme, tone and message. It works with your layout, grid and
color choice to create a well-rounded design.
Your choice of typefaces and your technique of setting type give your
composition its character, pace and style. Not only does it give the copy
legibility, it also helps the reader gain a greater insight into the
subject of the design.
A simple illustration of how influential typography can be is to look at
the same text with different typefaces. Notice how typography can define
and alter the message
Looks hand drawn
Has flicks on letters

3. FontFamilies
Many fonts today have something called a Family, this means
a selection of fonts may have the same name but just
different versions of it, for example American Typewriter
has many different versions from Condensed light to Bold

4. KerningandLEading
Leading - this is the gap between each of the lines in a
paragraph, you can change this by selecting all the text
and pressing CMD+T to access the character panel (It should
be on the RIGHT hand side), in here you should see a drop
down box like this on the right hand side of the
drop down box, have a mess around with the PT size until
you get the size you desire
Kerning - Is the adjustment of the horizontal lines between
individual characters in a line of text. To adjust the
kerning levels once again press CMD+T when the text box is
selected, a box should appear on the right, find the drop
down box that looks like this the default is 0 but
you can go between -1000 and 1000, once again have a go
until you get the look you want
