The ability to effectively use an existing lens has a much greater impact on the sharpness of the photo than the choice of the lens itself. The aperture number is the most important of the shooting parameters that affect the technical quality of the image. The difference between different aperture values of the same lens may be much more noticeable than the difference between different lenses at the same aperture.
Aperture f / 1.8 f/1.8
Aperture f/2.8 f/2.8
Aperture f/4 f/4 Continue reading
White balance is an important tool for managing the color palette of a photo. One of the advantages of a living person over a digital camera is that a person sees white objects white regardless of the color of the light source due to the inherent color constancy of human vision. Forming a visual image, our brain uses not only signals directly from the light-sensitive receptors of the eye, but also information about the type of light source, as well as our knowledge of what color an object should be. The digital camera is much more primitive, but it is helped by the ability to adjust the white balance. This is a parameter that allows you to change the color of your photos in accordance with changing lighting conditions. Continue reading
The colors of objects that we see are not a property of the objects themselves, but a property of our vision. Grass looks green only because light rays reflected from it with a wavelength in the range of 500-565 nm, falling on the light-sensitive receptors of the eye, cause the brain to feel green. Having got used to the fact that the grass is usually green, we see it green even in unusual lighting. Human vision is characterized by color impermanence. Our brain adjusts the color balance so that objects retain their natural colors for us as much as possible, regardless of the color of the lighting. White paper seems to us equally white, that in the daytime, when it is illuminated by cold light pouring from the window, that in the evening, when the warm light of incandescent lamps falls on it.
