What is the differences between ' painter ' and ' artist ' ? I am so confused with it.
A painter is one who paints (anything, on anything). An artist is one who approaches solving a problem in a non-engineering, heuristic way (for sake of argument, I do realize some engineering solutions can be so beautiful as to be artistic)
A painter is an artist, one who paints signs is a commercial artist, but an artist may not be a painter. ie a sculptor
Without getting too philosophical, the person who makes your coffee might be considered an artist (in making coffee, not as an alternative occupation) in the same way as "beauty is in the eye of the beholder", depends what you think. But they would not be considered a painter.
