There are currently two very strong exhibitions running at the Triskel Arts Centre in Cork. Each, in their respective ways, present artists who are absolutely clear about the vision, intention and final realisation behind their artwork.

In Gallery One, Eoghan McTigue's installation consists of a single free-standing 12 feet by six feet photograph showing a close-up of a blank electronic billboard (a post-modern equivalent to American Hyper Realist paintings of shop-fronts and signage).

The forceful presence of the object within the composition signifies the artist's interest in the small physical details of the subject. But as well as this, McTigue is interested in the sign's function, imbuing its essential mundanity with a significance that would normally not be afforded to it.

His homage to this blank screen is perhaps a vehicle for exposing our consumer-driven mentality as it is, waiting to be replenished with a stream of highly suggestive and forceful marketing messages, and in some respects as vacant as the sign itself.

In Gallery Two, Colin Crotty displays a maturity and conviction not often seen in such a young artist. His work is an object lesson in how even the very materials of a painting can speak volumes. The pigments - while largely divorced of hue - are used with such vibrancy and confidence that every part of the support is alive and demands attention.

The imagery employed is deceptively straightforward - namely figures within a landscape. But the complexities are such that there is conflict between rational and distorted space, while the inhabitant figures weave in and out of view like will-o'-the-wisps expelled from a ghostly quagmire, defying viable mass and dimension.

This is painting as discovery - not only for the artist, but also for the viewer. These landscapes act like triggers to tap into a long-lost instinct for wild open spaces - a yearning to embrace its potential and to be overwhelmed.

Runs until August 31st
