Isern is an old school painter, artist of the truth; he knows that painting is the combination of knowledge and sensibility, that painting is really painting avoiding the easy way. He has this lesson well learnt. Although then comes the added value of the minimum, of the sum of minimums which gain strength, consistency and establish the distances. It is the conjugation of the pertinent lights, existing on only a few occasions although certain and real that Isern knows how to capture; it is the shade of the colour, it is the touch of the atmosphere, is the vision of the distant mountains.… they are creator elements that he handles very well and that when united confer his work a special stamp. Almost anything and at the same time almost everything. The rest is knowing how to paint, the added value of the minimum is a level to which not many reach. Landscapes of different geographies, from the Canary Islands to the Picos de Europa, from the Pyrenees to the Montseny, from the countryside of Tarragona to the valleys of Andorra; which entail atmospheres and lights with a special tone that Isern knows how to express with perfection. It is certain that he dominates the technique. And it not less certain that each one of his works is a challenge, a step forward, a demonstration of knowledge and possibilities.

Jordi Isern knows how to be strong and at the same time poetic in his paintings. He revoques his sensitive soul in each one of the paintbrush's movements, which slides on a palette rich in colour. He sings to nature from the lyricism, although he does it by means of the impact, in such a way that he brings to bear a wide register of possibilities at the precise moment. All the landscapes he presents are loved by him, in an intense manner that he uses for a passionate devotion, to what he most likes and pleases him which is painting. Isern is very demanding with his own work, always searching for the light, as his first imperative. He ennobles the landscape, to which he gives elegance with the yellow of the wheat fields or with red poppies in orgy of colour. All of this is a consequence of the command that he exerts in his work, and the capacity to see and observe which makes him a painter of large perspectives with an amazing serenity. In his work, Isern pays special attention to the woodlands, which he reflects in an excepcional manner, as well as the distant mountains, always with soft and faint lights, virtues that place him, among others, in an uppermost position within the Spanish landscape painters.
