Question

Rubber Stamp Sample Accuracy

I've been using Photoshop since version one, and one thing I never understood is when I'm sampling an area to rubber stamp, why is the grain, or noise, not part of the sample? It's always a situation where all of that kind of goes away in the sample and then I have to select that area and add noise so it matches.

It makes no sense to me.

    The clone tool will reproduce the sample exactly, providing it is a raster content of the layer(s) you sample from.

     

    What it won’t copy is an effect from a Layer Style, like this texture, if you are using the clone tool on a different layer (with it set to All Layers )

    If you using the clone tool on the same layer that the layer style is applied to, then the texture will show in the copied pixels.

    Hi Chris,

    The Clone Stamp tool will be affected by a couple of things, 1. the softness or hardness of the brush edge...2. the size of the brush you use. What is the softness of your brush? I would suggest using a soft edge brush with the hardness set to a higher percentage like 70-90%. And, since you have been using Photoshop since version 1, then you understand to use a brush size that is appropriate to the area you are cloning.

    Here is what I have found in regards to the softer look to the clone stamped area--if you are using a soft edged brush (low number like 0-60) then the softness of the brush edge is what is affecting the sampled area you selected. It is not picking up all the pixels you sampled or painting with them. The softness is a direct effect of the edge of your brush. If your brush is harder (like 70-90) then you are painting with more of the sampled area which would include any texture or grain. I do not suggest painting with a 100% hard edbe because then you would see the hard edge line where you paint.

    Try the harder edge brush (maybe the 90 first, and if you are seeing a sharper edge where you paint, then try changing the hardness down to 80 or 70) and see if your cloned area has more of the grain and less softness. Let us know if you see a difference!

    I would never rubber stamp with a hard edge and I don’t know what you mean by “use a brush size that is appropriate to the area you are cloning.” I’ll try a less soft edge, thanks.

    Hi Chris!

    What I mean by appropriate is you would not want to use a really small brush to paint over a large area—you would introduce more interpolation by the softness of the edge. 

    The most important part of my post is the brush edge softness size you select to not introduce the softness and lack of detail that you were talking about in your post.

    What edge softness do you usually use?

    Someone with better eyes and monitor than mine --- and more knowledge about possible smoothing that happens when “rubber-stamping” -- may be able to give you help.

    I don’t see much difference between the two crops: too small (144px x 113px x 72dpi) besides the lone hair in the before. Sorry.

    I suggest you post a sample for others to examine and try to reproduce.

    Which tool are you using to grab your sample?
    Selection>Edit>Define Brush -or- Pattern?

    It sounds like you’re saying that, if an item in an image has grain/noise surrounding it, that if your selection is loose, then the noise is lost.

    This isn’t as dramatic as I’m used to seeing, but the noise in the rubber stamped “after” (on top) image are smother than the “before” image on the bottom.
