Vondada, if your halftones are coming out too pixelated out of the bitmap your not working at a high enough resolution or your setting your dots too small.
Honestly, Ive used the bitmap halftone many times, but the I run it through livetrace in illustartor, it takes out the "perfections" adds some uneaveness, same as a crappy old photcopier would.
With this poster, its obvious hes just gone throguh the first part of the equation, the halftone LOOKS photoshopped. For some people, thats fine, for others, it looks lazy and un-legit. Just my opinion, viva la halftone nazis.
I grayscale and then just apply the color halftone, ends up with black dots. I've tried it grayscale>bitmap but the dots never come out circular, they're always pixelated or fuxxored. I like the letter and illo on this, but I was expecting it to say Zach Hobbs.
convert image mode to grayscale, adjust contrast as necessary, convert image mode to bitmap, set your resolution, and choose halftone screen as the method, then set frequency and angle as desired. done. it's a trial-n-error process to get what you want.
if what you want is dots, then yes photoshop can give you the same dots printers have been using to put ink to paper for a loooong time. There are forums about how to do it right. You can tell a bad from a good usually.
richie, i could never argue with you nor am i trying. yes, 22,52,82 are the angles used to prevent moire, but i just stick with em cuz they look good. honestly, anything other than 90, 180, or 45 just looks better to me. a little less obvious, that's all.
