Midjourney has introduced an image enlargement feature, allowing users to scale up their generated images by up to four times, thereby enhancing image quality. This function is applicable to both newly generated images and old photographs, adding more detail and clarity to the images. Although four times the enlargement requires more computational resources, users can utilize this feature in Fast mode. This functionality addresses the previous issue of small image pixels, offering users more creative and editing options. Midjourney plans to continue improving this feature to optimize users' images.
