Black and White printing, is a minimalistic print form which uses low cost ink, and monochrome printers are often faster and require low maintenance than color printers, making them suitable for large, low cost, print jobs. Black and white is ideal for text-heavy documents, technical drawings, and other materials where clarity and accuracy is more important than Hue or colors. Most importantly, Black & White printing, reduces environmental impact. Monochrome printing can be more energy-efficient and is less wasteful than color printing.
Use this app to convert your photos or images easily, to striking black and white images, for a successful and environment friendly printing business.With the Black and White color edit option, you can convert your photos to greyscale pictures, online, in seconds. the color conversion operation includes changing hue, saturation, contrast. You can also easily adjust lightness, contrast, manually according to the light condition of the original photo or image. Increasing contrast means, you will be increasing black and white shades, and objects will become more prominent.
An RGB (Red, Green, Blue) color system is used for the display of images in digital systems, such as mobile phones, televisions, computers etc. CMYK (cyan, magenta, yellow, and key-black), is often referred to as color model, primarily used in color printing. The major difference is that in a RGB color space, all the various colors are resulted from the mixing of red, green, and blue; but in a CMYK color system, all the colors are results of the mixing from cyan, magenta, yellow, and black. RGB color space is also more near to human color sensory than CMYK used in printing terms. When the same amount of contrast colors such as red, green, blue is mixed, it will display a neutral, gray color, or black or white. In color adjustment, to reduce the intensity of one particular color is to add in the contrast color.
Additive mixing occurs when beams of light are combined. The colour circle (first descovered by Newton), is useful to understand how mixing beams of light can generate various colors, we see in the rainbow: violet,indigo, blue, green, yellow,orange, and red. White is at the centre and is produced by mixing light beams of approximately equal intensities of complementary colours (main colors that are diametrically opposed on the colour circle). mixing light beams of red and yellow gives orange, red and green gives yellow, mixing red and blue light gives magenta, and mixing blue and green light gives cyan. The three additive primary colours are red, green, and blue; this means that, by mixing the colours red, green, and blue in varying amounts, almost all other colours can be produced. And, when the three primary colours are added together in equal amounts, gray colors, black, or white can be produced.
Using this online photo color editing service, you can change the colors of your photo, which is actually a process of editing red, green, blue components of the color pixels. Similar operations are also called color filters. Thus, you can create special effects, by enhancing, reducing or filtering red, green, blue color components of photo pixels
The Hue is what we most often think as color. It’s calculated in degrees of the color wheel, and it refers to a color wheel that goes from red, to yellow, to lime, to aqua, to blue, to magenta, and finally back to red. Accordingly, 0° on the hue color wheel is red and then 360° is red again. Hue always refers to the base color.
Saturation refers to how pure or intense a given hue is. 100% saturation means there’s no addition of gray to the hue. The color is completely pure. A hue with 0% saturation appears as a medium gray. The more saturated (closer to 100%) a color is, the brighter it is. Low saturation colors, appear duller.
Lightness (or brightness) is the amount of white or black mixed in with the color. It’s also calculated as a percentage value between 0% and 100%, which means 0% lightness will also always be black.
Using this online photo color editing service, you can change the hue or colors, without diminishing color balance or beauty of the image.
A desaturated color appears pale or washed out, while a highly saturated color appears vibrant and rich. Lightness refers to the amount of light in a color, indicating its brightness. A color with low lightness is dark, while a color with high lightness is bright. Lightness is sometimes referred to as brightness, especially in the context of image editing. While saturation and lightness are distinct color properties, they can affect each other. When reducing saturation, a color becomes more pale or washed out, which can appear lighter or darker depending on the base color. Adjusting lightness can also affect how saturated a color appears, as increasing lightness can make a color appear more white, while decreasing lightness can make it appear more black.
Using this online photo color editing service, you can change the saturation, lightness, and contrast to create special color effects, and amazing images.
