Create a highly detailed and photorealistic image of a man's hand holding a smartphone. The hand should have a small, noticeable blister on the finger used for scrolling, illustrating the impact of prolonged phone usage. The blister should appear slightly reddened and raised, emphasizing its cause from hours of scrolling and searching on the phone. The image should capture the texture of the skin, the sleek design of the smartphone, and subtle lighting that highlights the features of the hand and the blister. Ensure the image is rendered in full HD for the best quality, make it full realistic
