How to take high-profile and low-key photos

High-profile usually uses a white background, and then the light makes the background very bright, which is equivalent to a pure white background highlighting the main body. Low profile is the opposite of high profile. The focus of high-profile and low-key is exposure. You can increase the exposure appropriately when shooting high-profile, and reduce the exposure appropriately when shooting low-profile.

High-profile: people keep a certain distance from the background, the background uses stronger light, and people measure the light. The background is overexposed to form a bright tone, and the brightness of the background should not be too strong than the main body of the character, otherwise the highlights will overflow and the picture will be foggy. In addition, be exposed to the dark parts of the characters. Because there are few external exposure meters in modern photo studios, photographers often deal with them by experience and add another exposure after routine metering.

Low-key: the distance between the characters and the background is widened, and the background is darkened as much as possible. At the same time, the light of the character should not reach the background as far as possible, and the light should be measured by the bright part of the character. The background exposure is seriously insufficient to form a dark tone, which is a low-key picture.
