The tiny dots that are visible on photo images are called pixels. There are generally thousands of pixels in a small area of a photograph. The larger the number of pixels in a small area, the clearer the photograph appears.
Oddly enough, they're just called "dots," and are part of what's commonly known as a "halftone screen." The number of dots per inch determines the resolution of the printed halftone photo (the more dots, the sharper the picture -- 150 dpi allows for much finer detail resolution than 72 dpi). The reason this effect was required is that offset printing is not capable of reproducing shades or gradations of tone -- there's either ink on the paper or not. Reducing a continuous tone photo to a series of dots allows it to be reproduced on a printing press. Without the dot structure, the press would simply print a blotch of ink. Traditionally the halftone was achieved by laying a reusable, semi-transparent screen of the desired frequency (number of dots per inch) over high-contrast photographic paper on an enlarger (or by a similar process on a "line camera," but that's a whole 'nother topic). Bright areas of the picture were thus translated to small dots on the paper; darker areas comprised larger dots. Nowadays, most pre-press operations use scanners, computer graphics programs and digital output systems to produce halftones.

The dots on a fern plant's leaves are called sori. Sori are clusters of sporangia, which are structures that contain and release spores for reproduction.
The fern plant you are referring to is likely a Polypodium fern, which is known for having rows of little black dots on the back of its leaves called sori. These sori contain spores, which are the reproductive cells of the fern and are not harmful.
Pointillism was formed in France in the late 19th century. It was pioneered by artists such as Georges Seurat and Paul Signac, who used small dots of color to create images when viewed from a distance.

The resolution required for high-quality photo prints is typically 300 dots per inch (dpi) or higher. This ensures sharp and detailed images when printed.
The significance of photo DPI, or dots per inch, is that it determines the resolution and quality of an image. A higher DPI means more dots are packed into each inch, resulting in a sharper and more detailed image. Lower DPI can lead to pixelation and a loss of clarity in the image. Adjusting DPI can impact the overall sharpness and quality of printed or digital images.

A computer screen is a grid work of small dots of light called a bitmap graphic. This is how computer monitors and televisions work.
For high-quality prints, the best resolution for photo printing is typically 300 dots per inch (dpi) or higher. This resolution ensures sharp and detailed images when printed.

yes
the dots are UFO lights but im not sure what year they were taken. :)
DPI (dots per inch) is the most important statistic for photo printers. This is the best indicator of the quality of photo that the printer will produce.
Usually, no. There's not a huge price difference in the cost of digital printing vs. photo printing, but the quality of photo printing is still higher. Digital printing involves printing tiny dots of color on paper to create an image while photo printing is done on photo paper where you don't see dots.
