No. To increase darkness, you decrease the amount of light reflected. To increase contrast, you increase the extremes of colour.
For example, if you have a picture made up of areas of black, white and grey, and you want to increase darkness, you replace some of the white with grey and some of the grey with black. If you want to increase contrast you replace grey with black and white. Increasing darkness decreases the amount of white; increasing contrast decreases the amount of grey.
Mammals and animals can be the same thing.
contrast
Nope yes you can same thing with the sky
The contrast
thats impossible, they are two words to describe the same thing
No, there is either lots of light, little light, or no light. But darkness isn't technically a thing.
Donna couldn't see a thing in the darkness of the closet.
dark spot
Yes
Contrast= difference Comparison= same
as far as i am aware there is no translation for shadow, but as the goddess of night and darkness is called "nótt", it could be used for the same thing.
Yes, or the difference in luminance, which is pretty much the same thing.
