The number and shape of aperture blades
The arrangement of the lens aperture affects not so much the quality of the blur as the shape of the blur circles. In fact, so-called blurring circles rarely have a perfectly round shape. They usually look like more or less regular polygons with the number of sides corresponding to the number of diaphragm lobes. The aperture in Nikon lenses has 7 or 9 lobes, in Canon lenses – 6, 7 or 8 (occasionally 9). The more petals there are, the more rounded the blurring disk looks, and an odd number of petals usually produces polygons that are more pleasing to the eye. Continue reading
Good exposure is critical for getting high-quality photos. However, the essence of the exhibition is very simple. Exposure is just the amount of light that hits the photo sensor. The process of shooting a frame is sometimes called exposure.
The exposure can be reduced or increased. That’s all you can influence. A smaller exposure makes the frame darker, a larger exposure makes it lighter. A lack of exposure is called underexposure, and an excess is called overexposure.
Correctly exposed image.
Underexposure 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
