The picture shows a green, wide and tall meadow with large green trees on the edge of the horizon in the upper third of the picture and a girl running through the meadow. From the upper edge in the centre, bright yellow rays of sunlight stretch across the middle of the picture and bathe it in warm light. In the centre of the picture, a little girl in a knee-length, sleeveless white dress is walking across the meadow with her back to the viewer. Her long blonde hair blows away from her body to the left as she moves. In addition, as she runs, her left arm is loosely behind her back and her left foot is bent upwards so that the entire underside of her foot can be seen at the end of her dress.

The picture shows a smiling man holding a tablet on which ista's Energy Management Minute View is displayed. The man has brown hair and is wearing black glasses. He is wearing a beige and grey striped shirt and a blue blazer over it. He is standing in the centre of the picture and looking directly into the camera. A modern office can be seen in the background. On the left-hand side of the picture is a wooden shelf in front of a black wall, decorated with long hanging plants and various objects that give the impression of awards. On the right of the picture, two women are sitting next to each other at a white work table covered with various work items. The woman in front, whose long black hair and beige loose top are visible, rests her arms on the table and has turned her head towards her colleague, so that only the back of her head is visible. The woman next to her has long blonde hair and is wearing a light blue shirt. Her side profile is recognisable. The entire background is blurred so that the focus is on the smiling man with the tablet.

The picture shows an electric car that is being charged. In the foreground is the car's charging socket, into which a charging cable is plugged. The cable is connected to an ista EV charging station, which is outside the picture. In the background, slightly out of focus, is a man in a light-coloured suit talking on the phone. He has a relaxed posture and is leaning slightly against the car. The scene probably takes place in an urban environment or in a company car park, which is indicated by the modern buildings in the background. The image conveys an atmosphere of modern technology and environmentally friendly mobility.

The picture shows a man sitting on a balcony in an urban environment. He is wearing a dark blue suit and a white shirt and is sitting relaxed at a small black table on the lower half in the centre of the picture. On the table in front of him are a laptop, a notepad with a pen and a coffee mug. The man has rested his legs on the balcony railing and is holding a telephone in his left hand while talking on the phone. The balcony is richly decorated with plants. On the left of the picture, climbing plants stretch up the wall, taking up almost the entire left side of the picture. Below the climbing plants are several pots of flowering plants and greenery arranged along the floor of the balcony. Above the man, stretched across the balcony, is a string of lights with several light bulbs that extends from the top left-hand corner to the right-hand side of the picture. In the background you can see a row of multi-storey buildings in various shades of yellow stretching across the top and centre of the picture. Behind the buildings is a park-like landscape with many trees that further break up the background. The sun seems to be either rising or setting, giving the picture a warm, golden glow. The view from the balcony extends over the roofs of the city.
