RE: digital negative possibilities for gum

[Keith Gerling <Keith@GumPhoto.com>]



Someday I'm going to read the manuals and learn just what all of those Mode settings actually do! 

 

I'm not sure if my comment regarding the Soft Light effects and noise is actually cogent to this discussion of bitmaps and whatnot.  Maybe not.  But adding a filter effect, such as Noise is like putting a window screen in front of the image.  It just Sits There and calls attention to itself.  With Soft Light, the noise is imbedded into the image, and yes - it just looks natural.

Keith,

I use the same method and it works very well.  I usually use a setting for amount of between 8 and 12, but  it depends on the image and the image size & resolution. 

I also set it to Monochromatic and use Uniform.

Filter>Noise>Add Noise

Oddly enough though, I like this method because it doesn't produce grain in the deeper shadows and blacks—it looks more natural to me.

Best Wishes,

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.
