It's Friday! There was no prompt last week because I sort of went into lurk mode - it's a bad habit that I need to work on.

This week's prompt is black and white.

Whether it's a two-tone cat or something quite mundane made dramatic with filters, I want to see how the lack of colour can be a focus of your shot.

Usual rules apply: No NSFW and no shots you didn't take yourself.

I expect you can guess the difference between grayscale and black and white based on the names - essentially black and white contains only those two, while grayscale has assorted gray shades as well. Black and white can look casually grayscale at high definition where the blacks and whites are mixed (a 100x100 square with 50% black and 50% white equally distributed throughout is going to look gray on first glance at a distance).

I can't say if your image is grayscale because I have not properly looked at it - it just feels that way on first glance. I'm also not familiar with digikam so I don't know what it defaults to when converting color to monochrome.

I do like the composition, btw.

Any digital image is actually red green and blue, those are the colors of the pixels on your monitor. When there's enough of them your brain is tricked into seeing other colors. To get even more meta, all colors are just made up by your brain.

So I don't understand your distinction between black and white, and grayscale. Whether it's a gray made of black and white pixels or a "pure gray" doesn't matter, it can look the same. Unless it's a style where the pixels are supposed to be visible, e.g. pointillism.

Modern monitors do black (pixel off), and white (all three colours at once), as well as grayscale (method varies depending on display type). All of this means that images are displayed in the colors they contain. Or in this case, don't contain.

Grayscale will display differently to black and white or sepia or full colour.
