An animated film cosists of a number of frames that show the characters is slightly different poses. When viewed sequentially the frames give the impression that the characters move.
The individual frame making process has changed over the years - but the basic method of putting together an animation is the same:
Using the stroryboard an artist is commissioned to draw a sequence of images - each one in a slightly different position - to show movement as time progresses - including 'lip synchronisation' for speech or singing. Therefore they are also given the sound track to 'fit' it too. For a big animation many artists will be employed and working to the storyboard specifications is very important. An animator may spend weeks working on a few minutes of action, while a layout artist is spending a similar amount of time on the background.
The above image sequence shows how the 'blink' was achieved. See here for detail of how the other effects wre acheived.
Stage 4
Those sketches are then played in sequence to ensure the animation is correct before any detailed work is done on them.
Stage 5
The artist can then work on the detail - colour, rendering, shadow addition... and background - that is sometimes done by another artist!
This site sells original art for cell - you can use it to see the quality of images - and also the stages they go through.
This is another site that sells cel originals - it has sequences of cells of such characters as Bugs Bunny - check out the Chuck Jones section.
