Yolie,
Welcome to
RP! It's great to see a sample of your restoration work and I hope we see much more. You did a very nice job on what I consider a very nice piece.
This may look like a lot but it actually only took a few minutes. Here is what I did.
I duplicated the layer and turned off the original (I never work on the original).
Adjusted levels on this new layer.
Ran in neat image. Neat image removes noise and also grain (download a
demo version here) .
Duplicate this layer and run filters>noise>dust and scratches.
While holding the alt key I clicked the add new layers mask at the bottom of the layers pallet. This filled the mask with black and covered the layer. Now with a small brush I can simply paint the areas I feel need touching up. For more on this technique try
this tutorial.
As an antique photo I decided I like a little film grain so I ran the noise filter with the monochrome box checked.
I posted 2 versions. on the first, I removed the yellow cast by clicking image>mode>grayscale.
On the second I increased the sepia tone look by adjusting hue/saturation with the colorize box checked.
