SID Short Exposure Image Dataset

SID stands for See-in-the-Dark and contains 5,094 short-exposure RAW images and their corresponding long-exposure reference images.

• The dataset contains indoor and outdoor images, where the illumination of outdoor scenes is between 0.2 lux and 5 lux, and the illumination of indoor scenes is between 0.03 lux and 0.3 lux.
• The exposure time of the short exposure is set to 1/30 to 1/10 s, and the corresponding exposure time of the long exposure is set to 100 to 300 times, that is, 10 to 30 s.
• There is no displacement between the short exposure images and their corresponding long exposure images.
• We randomly selected 70% as the training set, 20% as the test set, and 10% as the validation set.
• Images were acquired using two cameras: Sony αα7S II and Fujifilm X-T2.
