One of the most charming contrasting color effects you can get in photography is by using infrared. An easy way to understand near-infrared light is to think of it as the color of the rainbow next to red, a color that is invisible to the human eye. But near-infrared is not the same as thermal imaging.
Because everyday objects reflect infrared in proportions that differ sharply from that of visible light, the tonal relationships are wildly unexpected. Such near-infrared techniques used in photography give subjects an exotic, antique look. Green vegetation becomes white, whereas human skin becomes pale and ghostly. The resulting images look alien.
Even Photoshop cannot mimic the original picture of infrared photos due to different color, textures, leaves, human skin and plants. IR photography is a different type, and some people may not like it. So to explore more about these, we need to see few examples, and I hope it will expand your horizon of photography interests.
