When scanning black and white negatives, the moment when the negative image is inverted into a positive is captivating. No matter how much I study the negatives, they always seem blurry and difficult to interpret. The positives suddenly seem sharp and the scene presents itself clearly.
But sometimes a negative stands out on its own. It seems ethereal, or occasionally more real than when converted to positive. Some subjects work better than others - a human face often looks demonic in negative form as the eyes turn black with white pupils. But natural scenes and architecture seems to have their own charm as negatives.
As most photographs are subjected to some sort of post-production (whether in the darkroom or Lightroom), it seems that a conscious decision to not invert the negative is also a creative possibility.
