Resizing Photographs
Accurately changing the old to new
Resizing Counts!
• If you resize a picture incorrectly it will
be immediately noticed.
Need to Shrink
• Enlarging photos will likely have poor results.
• The picture will end up being blurry or
pixilated.

Bigger is Better
• Reducing the picture size will not alter
the quality or clarity.
Real Applications
• When working in any type of media you
will have fixed sizes that a picture needs
to fit into.
• The customer does not want a poor
quality reduction so you need to figure
out the exact amount the picture needs to
be reduced.
Example
• My total workspace for the web page is 1024
X 768 pixels.
Example Pt 2
• The customer wants three pictures on the
side of the page, they need to fit into an
area which is 400 X 300 pixels.
• One of the pictures we have is currently
900 X 400.
• We need a way to accurately reduce this
photo.
Example Pt 3
• Current Size 900 X 400
• What would the width be if the length was
400?
Second Example
• We have a picture 800 X 600
• Will it fit into an area of 300 X 275 if we make
the width 275?
Second Example Cont.
• We will use maximum length instead of
width.

Maximum Area
• We have a photo that is 700 X 500 and we have an area
on a web page that is 350 X 275.
• If we use the length as our first dimension the picture
would resize as 350 X 250
• If we use the width as our first dimension the picture
would resize as 385 X 275
• The first equation uses all but 25 pixels and the second
number is too large, so the size using the maximum
amount of area is 350 X 250.
Maximum Area Practice
• Photo is 600 X 800. The space provided
is 525 X 350.
• What is the best size to reduce the photo
to, using the maximum amount of area?
Max area Practice
• Using the length it ends up being
525 X 700, which is too large
• Using the width the picture would be
263 X 350. This would be the best choice.
