A reproduction device comprising:

• an acquisition section configured to acquire a logically single data unit including first still image data and second still image data different from each other in luminance dynamic range and reproducible independently from each other;
• and
• a reproducer configured to reproduce either one of the first still image data or the second still image data included in the data unit acquired by the acquisition section.

A reproduction method comprising:

• acquiring a logically single data unit including first still image data and second still image data different from each other in luminance dynamic range and reproducible independently from each other;
• and
• reproducing either one of the first still image data or the second still image data included in the acquired data unit.
