Gendelman was born in the region of Crimea in what is now the Ukraine. Ever since she was a child, she was inspired by the cityscapes of the region as well as the natural beauty of the nearby Caucasian Mountains and the Black Sea. She gained a passion for art when very young and this fueled her desire to develop her skills throughout school and later on in university. She then traveled to numerous cities in both Europe and the Middle East, letting her artistic style evolve. She eventually settled down in Israel, where she has remained to this day.
Focusing primarily on cityscapes, Irena uses the shadows and skylines of different urban environments to create detailed paintings full of passion and life. Opting for subdued colors and fine lines, she creates art that offers the viewer so much without overwhelming them. Her paintings are also textured, adding yet another level to the artworks that she so lovingly creates. These techniques combine to produce works of art that seem solid yet light, creating a sense of ethereal realism. All of this is possible thanks to the experience and the skill that Irena has built up during her many years at the canvas.
