RE: digital negative possibilities for gum



For what it is worth, here is a method to add noise that (I feel) comes closer to duplicating grain in a silver neg:
 
1) Add a New Layer
2) Fill it with 50% Gray
3) Adjust the Noise or Film Grain filters until the degree of grain is achieved.
4) Change the layer Mode to Soft Light
 
The result is more grain in the shadows than in the highlights.

You hit it on target with Photosop. My idea of adding noise was to play with RGB separatrions so each channel has a different noise pattern. I am goin to try the bitmaps after I split the channels into RGB.

Hi all, I used diginegs with silver emulsion some years ago to get grain into images that were originally shot on 25ASA film - kinda roundabout way of getting what I wanted (why didn't I shoot in 3200 to start with?) but a useful experiment. The prints were, in fact, very successful and the beginning of my experimentation with diginegs. I didn't use bitmaps, though, I used a monochrome RGB image and added film grain with the filters option in Photoshop. There are certainly hundreds of ways to skin a cat with Photoshop.

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.


Marek,

I know what you are getting atI have some color prints that were made from enlarging an area of a color negative and I really do like the effect of the dots of various color that make up the image.



Best Wishes,
