Correct Exposure in Food Photography

As I mentioned at the beginning of this section, correct exposure is achieved by balancing the aperture, shutter speed and ISO trio. I recommend using manual shooting mode when shooting with a DSLR. Manual Mode Manual Mode (M) is the shooting mode that you enter on your camera by determining the aperture, shutter speed and ISO settings yourself. 

Determining the correct aperture, shutter speed and ISO settings in manual mode may seem difficult at first. Fortunately, with developing technology, DSLR cameras help you easily find the right settings during the shooting phase, thanks to their electronic systems (light meter). DSLR cameras can show you before shooting whether your photo will be correctly exposed by taking into account the ambient light in line with the settings you make. A camera that makes measurements and calculations in line with the settings you see below informs you when your photo receives the light required for ideal exposure, by reaching "zero" value before you take the photo.

The exposure meter in our camera measures the amount of light reaching the sensor by entering the lens from the area where we point our camera, and allows us to see how our photo will be exposed before taking it, using our current settings with an indicator. The ideal exposure in this indicator is the zero point. Values towards the positive indicate overexposure, and values towards the minus indicate underexposure.

Thanks to the light sensor on the exposure meters, it measures the amount of light falling on the location and displays the aperture, shutter speed and ISO values required for ideal exposure on its screen. However, in order to read a value from the exposure meter, you must first enter two of the three basic values into it. The exposure meter in your machine works with the same logic. If you want to determine the depth of field, you must first enter the required aperture value and then enter the shutter speed that will balance it. As I mentioned before, keeping the ISO setting at the lowest possible value at the beginning will be ideal for a grain-free photo.

For example, you want to take a photo with a large aperture (new small f-value ☺ ) for a blurred photo and you set the aperture value to f/1.8, and set the ISO value to 100 for high image quality. You determine, the exposure meter of the camera informs you at which shutter speed you will capture the correct exposure by going to zero as soon as you select the correct value, that's all! (You usually do this by sliding the dial that controls the shutter speed or the setting you want to change.) If it is a shot related to movement, we can choose the appropriate shutter speed for how we want to control the movement and ensure that the camera gives the correct aperture setting with the lowest possible ISO setting. For example, if we want to capture the coffee drops jumping from the coffee cup in the air, if we set the shutter speed to 1/1000 or faster, we can freeze even the smallest coffee drop in our photo while it is in the air.
