Optimizing Resolution in Graphic Files

Goal:
Given a series of graphic files, the learner will be able
to select resolution, dimensions and file size to be optimized
for a variety of specified uses.

Tutorial Prototype Evaluation & User Testing
Five individuals with different levels of computer
skills went through the tutorial at various stages of development.
All had taken or used digital images either in their work or
personal endeavors.
Most
of the testers took about 10-15 minutes to complete the
tutorial and indicated that they thought it would be useful
to people new to digital imaging. Early testers commented
that they thought the illustrations helped them to envision
some of the concepts that weren't completely clear with
a text-only earlier draft.
In
addition to catching some navigational inconsistencies,
typos and a few mathematical errors (what's an order of
magnitude between friends...?) in the instruction, most
felt that it was too text heavy. In discussions, most thought
that a narration with bullet points of the highlights would
be more inviting. A couple indicated that, while audio might
provide a better experience, it might not be practical in
their work environment where everyone is in cubicles so
they could not listen during working hours. Alternatively,
several suggested breaking up some of the longer pages into
several pages. Due to time limitations, it was not possible
to try out these ideas.
Other
suggestions included having:
- interactive
graphics where the learner could click on buttons of different
resolutions to see the effect on images
- better
simulations of Photoshop menus where the numbers could be
more fully interactiv
- more
illustrations in general, especially on the practice pages
- navigation
at the end of the quiz to close the window or otherwise
indicate closure
One
other thing that I would do differently if I had more time
would be to create the bitmapped images larger, so that
their quality would be better when the Flash document is
viewed on a larger screen.
