Having fun with HDR (high dynamic range) effect, which is basically a way to manipulate the brightness level (or exposure) of a photograph by merging the tonal information from multiple exposures of the same shot to create one master output while preserving details from all the exposures. It brings out levels of detail in otherwise dull photographs, giving them a new lease on life. It can easily be overdone though, resulting in "otherworldly" photos.
Interestingly, HDR has been used since the 1850s,pioneered by French photographer Gustave Le Gray in his seascapes. Le Gray used one negative for the sky, and another one with a longer exposure for the sea, and combined the two in a single picture in positive. Below is his 1857 "Large Waves, Mediterranean Sea," an albumen print from two negatives.
