PHOTOGRAPHY TIPS: EXPOSURE COMPENSATION. Reduce exposure compensation by 1/3 to get true colours of redness of frangipanis.
You may need to reduce exposure by 1/3 to get less reflective
redness of petals.
What is exposure compensation?
As the name implies, exposure compensation is the act of changing the exposure values calculated by the camera to get an image that is correctly exposed or at least exposed according to our objectives.
Many
cameras have an exposure compensation function intended to make the
process easier whenever an automatic or semiautomatic exposure mode is
used. In general, it is a scale with zero as the central point and
allows you to change the exposure to + or – up to 2 or 3 stops. This
allows the photographer to change the camera’s exposure settings to
obtain darker or lighter images according to his needs without using the
Manual mode.

Exposure Compensation, How to use it to take better pictures?
How can exposure compensation help us to take better pictures?
Modern cameras have a unique ability to read the light and determine the correct exposure for most situations. However, there are still situations where the photographer’s intervention is decisive for creative or technical reasons. For this, exposure compensation is a fundamental and easy-to-use tool. All that is needed is to understand how it works.

Exposure compensation and exposure modes
Depending on the exposure mode we use when shooting, the exposure compensation will change different parameters. Let’s look at each case individually.
Manual (M)
In Manual or M, exposure compensation does not work. Manual mode gives the photographer absolute control overexposure. The exposure compensation is set by applying the desired shutter speed and aperture values on the respective dials. If ISO is set to Auto, in some cameras, the exposure compensation will work.
Aperture priority (A or Av)
When you use exposure compensation in aperture priority mode, A or Av, the shutter speed value will vary. The ISO value only varies if set to AUTO.
The aperture set by the photographer remains fixed.
Shutter priority (S or Tv)
In shutter speed priority mode, S or Tv, the aperture value will change when you use exposure compensation. The ISO value only varies if set to AUTO.
The shutter speed set by the photographer remains fixed.
Program (P)
In Program, or P mode, both the shutter speed and aperture values will vary according to the mode settings when you use exposure compensation. The ISO value will only vary if set to AUTO.
Finally, exposure compensation on an iPhone
On the iPhone, it is also possible to use exposure compensation. To do this, tap the screen once to activate the focus point. The square that marks the focus point has an associated light measurement area. With the square active, slide your finger vertically across the screen to change the exposure.
There are no values, but the result is immediately visible on the screen.
On newer models such as iPhone 11 and later, you can use Exposure Compensation Control to precisely set and lock the exposure for upcoming shots. To access it, tap the arrow, tap the exposure compensation icon +/- and adjust your exposure level. The exposure locks until the next time you open the Camera app
