Last time I looked, which may have been three years ago LRC had generic film grain in addition to the generic grain in the effects panel. I us a plugin called NIK by DXO. It has film specific grain simulations.
What kind of grain are you looking for ? Do you have any "film" with that grain? The easiest way to get color film grain for your own use is to cross process rolls of color film in black and white developer and sample that.
Good idea. I have some older Portra 160--I wonder what the concentration and development time would be in Rodinal? I guess I'll need to do some research.
Grain is grain, the dude wants grain. Grain is "film" I don't think anyone inspecting the grain of his DIGITAL HOAX is going to remove the magnifying glass and sayIf you want emulate colour film grain, most likely it is the de cloud "grain" you are wanting to emulate, not the grain you see when developing the film as black and white.
Nik color efex pro has real film simulation including grain adjustment see image article showing grain in a film simulation. https://lenscraft.co.uk/photography-blog/nik-collection-2-5-released-by-dxo/
I've been working very hard recently on emulating the film look for digital cameras and have settled on a grain method that's very close. First let's take a look at some film grain, shot at one stop intervals, scanned at 24MP and presented here at 100% magnification. Top row is the "digital" version, the average RGB values of the extracted film scans in the row below:

I think that most methods of simulating film grain involve taking a grain scan that's been normalised to an average of 128 RGB and then applying an Overlay blend mode. When we do that we get this, and it's very apparent that them middle grey patch is bang on but the amount of grain in the shadows and highlights is not:

Now, here's my method using a grain scan and a PS action. The amount of grain in the shadows and highlights of the digital row (top) is much closer to the film scan (bottom):

Here's how I do it in sRGB colour space in Photoshop:
Acquire a scan of film grain and make sure that it averages out at 128, 128, 128 RGB
Convert this and digital file to sRGB
Place grain layer over the digital file and resize if necessary
Change blending mode to Soft Light
Duplicate grain layer twice so now there are three Soft Light grain layers (the first two of these will take care of midtones and highlights)
Select the last grain layer which will deal with shadows and apply the following effects (not adjustment layers, we only want to alter this third grain layer)
Add HSL effect: Saturation +50
Add Color Balance effect: Yellow midtones -30
This gives use a highly saturated, and slightly warmed grain layer for the shadows
Then double click to bring up Layer Style menu
We're looking for Blend If
Leave "This Layer" at its default but set "Underlying Layer" to 0 0/85. So you're bringing the white slider down to 85, then Alt click to split that slider and bring the left portion all the way down to 0
Depending on the sharpness and resolution of the grain scan and the resolution of the digital image you might want to slightly blur the digital file. None of the fine details in the digital should be smaller/sharper than the actual grain.
That's it, all done! If you record the above as an action (use File>Place Embedded to import grain file) then you can batch apply this to folder of images. Duplicate it and double click the Place command in the action when you want to use different grain.
Let's have a look at a real world example.

I am looking for the best way to add some grain to color digital images, to take off some of the digital curse when making larger prints.
Sure. Digital has a crispness and smoothness that borders on looking airbrushed to me. Grain/dye cloud texture breaks that down and feels more organic. I can only print up to 13x19, but I have outsourced 20x30 prints. I don't have use or space for anything larger at this point.Can you describe the "digital curse" and explain how using grain will ameliorate it? For you, what is a "larger" print?
I am looking for the best way to add some grain to color digital images, to take off some of the digital curse when making larger prints. I don't need to simulate any particular film look, just want to add convincing color film grain. I have used DXO Filmpack in the past, but the version I have no longer works on my current computer. Buying the current version seems like a bit of overkill just for grain. Is there any other software or technique in photoshop that might work for color?
I like to be able to work the image in the darkroom, but I don't print color in the darkroom, just black and white. Therefore, color is shot digital and I want to bring it some of the organic look of my black and white darkroom prints.Come home to film?
Grain/Dye-Clouds (Film) = The Image (organic)- can look noisy of course
Digital Grain = Noise (Not the image)- is always noise, never the image (FujiX ACROS in-camera sim may be more related to the image)

It looks good! I'm glad it's working for you. Reading over my post I don't think my instructions were as clear as they could be but you seem to have figured it out.Here's a detail

I never use film simulations, just adjust raw files to my liking and add grain. The paper I have settled on is Canson Baryta Photgraphique, a satin sheet. I have tried matte papers and more textured papers, but the colors vary and lose intensity as compared to my monitor calibration. For black and white, the nicest reasonably-priced option has been Hahnemuhle fiber matte printed by Cone Editions.Along this line, perhaps: My Pentax K70 dslr has several appearance options, two of which are HDR versions. One of those is almost/sometimes too extreme... these options don't fake grain because (I assume) Pentax seems committed to a certain type of market...there's a Pentax-look.
