A hyper-realistic close-up of a slice of lemon cheesecake with a smooth, creamy, bright yellow lemon-flavored filling set on top of a buttery, golden-brown crust. Inside the cheesecake, there is a vibrant layer of rich blueberry jam, dotted with fresh blueberries, creating a bold contrast with the yellow filling. The top of the cheesecake is decorated with more fresh blueberries, and a light drizzle of blueberry syrup gently cascades over the slice. A couple of fresh blueberries are placed beside the cheesecake on a clean, neutral background, ensuring the focus is on the bright yellow cheesecake and the purple blueberry jam.
