Re: digital negative possibilities for gum


I find this grain idea in gum very interesting. I have been thinking of it for a while as well. I like a grainy or almost pointilistic look of some of the prints where I have mutilated each of the tricolor layer separately, where the image is made of irregular spotrs of primary colors. I have been trying to introduce grain into RGB separation via the grain commands. I have just played with it, not made any negatives as yet. I am looking for it to produce more brilliant colors.

Actually I have been priniting B&W prints on my Epson 2200 with black ink only, that is only one of the six inks. It results in what people call TRI-X look. SOmewhat grainy(not to the naked eye), but with outstanding crispness. And somehow the print looks "cleaner" and fresher that way. That is dots of dark ink on white paper is more appealing to the eye then a continuous gray layer.

Now, I have lost the original post, where is the bitmap command in photoshop?
It will be grat to meet you next weekend at Clays
