compensate raising the ISO
Some cameras have a function to preview the depth of field. To understand how it works, you first need to know what the depth of field is, for example, you can read about it here.
Modern cameras always perform focusing at the maximum aperture. For example, if a standard 18-55mm F / 3.5-5.6 lens is used, then focusing will always be done on apertures from F / 3.5 to F / 5.6 (depending on the focal length). Continue reading
A histogram is a chart based on the tonal distribution of pixels in a picture.
From the left to the right (horizontally) the brightness is indicated, and from the bottom up (vertically) the amount of the photo area of a particular tonality. It is often said that vertical columns simply show the ratios of the number of pixels of a particular pitch. That is, the diagram shows how much light or dark shades prevail in the picture, how many green or red or other shades of colors in the picture are larger. Histograms are different. In photography, basically, three types are used: Continue reading
However, what is ISO in the camera settings?
ISO is a parameter indicating the level of sensitivity to light of its light-catching element (matrix or film). Mostly indicate the ISO limits for cameras (cameras). Although, the same parameter can be met not only on the camera, but, for example, on the flash. For a flash, leading numbers are usually indicated when using one of the ISO 100, or 200 values. The ISO sensitivity is indicated in special ISO system units. Continue reading
