We don't know yet which painting made it in since their list only included artists' names. To increase suspense they're withholding title and category information until the online exhibition goes up and the awards are announced in early November. Finalist paintings are also eligible to be chosen for inclusion in the live exhibition, a new facet added last year to tremendous fanfare and success.
The International ARC Salon is an annual exhibition created by the Art Renewal Center which has grown to be the most prestigious realist art competition in the Americas. Their website is a vast repository of classical realist art and receives over 5 million annual visitors.
