Choose Your Weapon!

There are very distinct advantages and disadvantages concerning the use of vector or photographs in design ideas.

Vector

Advantages

1. Vector tends to look very clean and can be more easily "tweaked" for the needs of the design by individual parts.  The "rough bits" of a design can be very easily edited out.

2.  Vector does not lose quality when the size is changed (thank you Kelly)

Disadvantages

1. Conversion to vector isn't perfect and is complicated to correct. 

2. You cannot get the rough or texture feel near as easily as analog methods, It'll almost always look technical.

3. Typically you're able to preview and correct before printing.  Printing costs will go down by quite a bit

4.  Expensive tools are required.  Buying this laptop and software obliterated my bank account.

Analog

1.  Sometimes easier and faster to produce in quantity then digital.  Photocopying alone makes digital work look like its standing still

2.  Less control....more mistakes

3.  Messier then digital.  Unless you break your monitor, you won't make a mess on the computer

4.  More expensive to produce due to mistakes or reiteration.
