current exposure value
Are you still unhappy with the sharpness of your images? Isn’t it too much you want?
A digital camera is basically not capable of providing absolute sharpness. Most photo sensors are equipped with a special anti-aliasing filter that slightly blurs the image so that any point of the original scene in all cases is perceived by more than one photodiode. This is called antialiasing (antialiasing) or smoothing and is necessary to prevent moiré-striped artifacts that can occur when photographing fabrics and other items that have a periodic, repetitive structure.

Modern cameras are equipped with a built-in exposure meter, which is able to automatically assess the level of illumination and select the appropriate values of the exposure parameters. If the exposure value offered by the exposure meter does not suit the photographer, he can either switch to manual mode and set the exposure independently, or, while remaining in automatic mode, use exposure correction. Exposure correction or exposure compensation is a forced change in exposure relative to the value determined by the exposure meter. Positive exposure compensation causes the camera to increase the exposure by a specified amount, and negative exposure causes it to decrease. For example, if the camera’s exposure meter allows one step overexposure under certain conditions, you should apply an exposure correction of – 1 EV to get a normally exposed frame. Continue reading
What could be simpler?
Take a picture;
Take a look at the histogram;
If the exposure is in order-it’s in the hat;
If the histogram indicates underexposure or overexposure, use exposure correction to increase or decrease the exposure, then go back to step 1.
Repeat the sequence until you are satisfied. Continue reading
