I personally like the second way more.
1, Clumpy film grain
Filter > Artistic > Film Grain
or
2, Impressionistic grain
a: Image > Mode > Lab Color. Select the Lightness channel in the Channels palette.
The Lightness channel controls the color values in the image but not the hues.
b: Filter > Texture > Grain. Select the Clumped grain type.
Return to the Lab channel to evaluate the result.
The resulting image is the softest and most impressionistic of all of the variations shown. Choose this method when you want the photograph to have a painterly quality, but retain enough detail to look photographic.
