He attended a primary school run by Piarists in Gorizia, where he began to learn to paint in the third year. He received his first training as a painter from the local artist Karel Keber and probably also from the painter Franz Caucig. In 1809, he left for Rome with the help of Austrian Archduchess Maria Anna, sister of Emperor Francis I of Austria, and count Francesco della Torre. In Rome, he studied painting with Domenico Conti Bizzani and in the Scuola del Nudo at the Accademia di San Luca. In 1814, he was awarded a silver medal for his drawing Study of the Apostople.

Between 1830 and 1855, he lived and worked in Trieste. He later moved back to Gorizia, and finally to his estate in Gradišče nad Prvačino, where he died in 1866.

The style of Tominz’s portraits was influenced by late Classicism and by the style of Viennese portrait artists of the Biedermeier period. The people in his portraits have sharp features and clear forms, but despite this the depictions are realistic, sometimes with an ironic touch. The backgrounds are filled with landscapes or the city from which the person depicted originated. Tominc also included objects that hint at the profession or the lifestyle of the person depicted. Inspired by Jean Auguste Dominique Ingres or Vincenzo Camuccini, he used cool colours and plastic models of people. He is however best known for his oil painting technique, his precise skills of observation and his rapid style.
