| There are no gray pixels there. If you close up, you will see only black or white pixels. This is a 2 bit (but saved as jpg) photo :) |

I understand the concept and the method used, but the 'impression' of the photo is that there is gray present. Hence, this type of challenge is fraught with danger to the submitter. |

| That's true, I think that's unavoidable. I think the challenge should be "2 bit photos only" instead of "BW with no grays" I probably put wrong wording there. |

| This idea came from "Shutterbug magazine Sept 2008 issue page18". Same wording, and a sample. I liked the sample, and gave the idea for challenge :) |

I like the idea too, we would just need to be careful about the wording. Don't forget that we have many literal DPC title and challenge description readers... |

This is a fascinating topic for a challenge, but I think way too many people would have problems interpreting the challenge and converting to 2 bit.
Edit: how are you saving? Is the final picture then converted back to an 8 bit jpg?

Problem is that you can easily have an "apparent" full range of tones in a two-bit image -- this is the principle by which newspapers have produced half-tone photos for over a hundred years.
If what you want is ultra-hich contrast photos, perhaps it would be better to use the term "posterized" -- the effect of reducing an image to a specified number (two or more) tones/colors. You can actually achieve this type of effect using (in Photoshop) either Image > Adjust > Posterize... or Image > Mode > Indexed Color. |

Converted to Bitmap, then Save for Web
Posturized (4)(I must be missing a step here... Grayscale first?)
Greyscale thend posturized to the smallest number
Indexed
I think I liked the Indexed best :) |
