Konwerter czarno-biały

Convert a photo to black and white. The conversion is weighted the way human vision is rather than by averaging the three channels equally: green contributes most to perceived brightness, red less, blue least. That is why a properly weighted conversion keeps a blue sky dark and foliage mid-toned, while a flat average washes both into the same murky grey.

How it works

1. Drop in one image or a batch.
2. Apply the grayscale conversion and check the preview.
3. Adjust the contrast if the result looks flat — removing colour often removes the separation between areas that were distinguished by hue rather than brightness.
4. Download the black-and-white image.

Good to know

Some photographs improve in black and white and some collapse. The ones that work have a strong range of brightness, clear shapes and interesting light. The ones that do not are usually those whose whole appeal was the colour: a red door in a grey street is the subject of the photograph, and in grayscale the door is simply another mid-grey rectangle. Worth checking the preview before committing, and worth keeping the colour original either way.
