Fully automatic or green mode does not need to be introduced. The camera thinks about everything here. Not only the shutter speed and aperture, but also autofocus, flash, white balance, in short, everything is under her control. Except that she doesn’t press the button herself… Although work is already underway in this direction.
Often, the AUTO mode is supplemented with an almost identical “no flash” mode.
Listen to good advice: if you are still shooting in AUTO mode, try at least experimentally switching to program mode (P). Continue reading
Today, any digital camera offers the photographer a frightening variety of shooting modes. Due to the fact that the instructions for cameras describe the features and purpose of a particular mode is very vague, it can be difficult for a novice Amateur photographer to determine which modes are really useful, and which are marketing nonsense. As a result, many people either spit on everything and shoot exclusively in AUTO mode, without trying to dig deeper, or, believing the authors of the instructions, try to use narrow-minded story modes (Portrait, Landscape, Sports, Macro, etc.), not suspecting that with a minimum of mental effort, you can achieve much more flexible and complete control over the camera without any damage to your own comfort.

Light falling on the photodiodes of the digital camera matrix is converted into an electrical signal. For this to happen, the number of photons that hit each individual photodiode must exceed the sensor sensitivity threshold. If there are not enough photons, the corresponding section of the frame will be completely black. If the exposure is excessive, the photodiodes are saturated with photons and the overexposed area turns out to be white. The ratio between the exposure values required to produce a completely black and completely white color is called the sensor’s dynamic range or photographic latitude. Continue reading
