Contrast. Contraste


There was a fallen bucket in my yard, and it took my attention the contrast of colors, the gray of the floorcloth, the bucket , the slab, even more gray the water stains. And in contrast, the yellow of the handle and the red of the broom.
The picture was filtered with a green color as background.


"Contrast is the difference in luminance and/or color that makes an object (or its representation in an image or display) distinguishable. In visual perception of the real world, contrast is determined by the difference in the color and brightness of the object and other objects within the same field of view. Because the human visual system is more sensitive to contrast than absolute luminance, we can perceive the world similarly regardless of the huge changes in illumination over the day or from place to place. The maximum contrast of an image is the contrast ratio or dynamic range. Contrast is also the difference between the color or shading of the printed material on a document and the background on which it is printed, for example in optical character recognition."

In the image above, I added faded colors but my intention was, at the same time, to emphasize the contrast between textures: the plastic, the concrete slab, the floorcloth.
We can have beautiful results from simple domestic objects.


And if I change the broom color, red for blue, and the stains become reddish, then the picture is more sinister, we could be cleaning spread blood somewhere.....
