*Before I start it needs to be said that this does not work very well with high colour (bright) photos and is recommended for use mainly with darker ones.*

5 (and a half) steps to reducing Grain
(de-speckling)

1 Open your grainy photo/picture (obvious i know)

2 Double click the "Background" and turn it into a layer (name it if you want)

3 go to the "filter" menu Noise>Despeckle. This removes a lot of the grain in the photo, but it's not the best; the reason we're using it is to get rid of the obvious grain
Note: not all photo's/pictures are the same quality, so it may be good on some and poor on others.

4 This next step may not be familiar to beginners,, but anyone who has played with Photoshop and said "Ooo what does this do?!" may have used it already. For those who haven't, its the "Levels" filter - ( Ctrl+L ) in Image>Adjustments>Levels.
Levels are useful in manipulating the levels of specific colours, as well as the RGB (all colours combined) of an image. For this tutorial you'll need to select RGB. With the Levels window open, slide the BLACK Input slider to the right, until your image becomes 'clearer'. You will also notice it becoming very dark. To fix this, slide the WHITE Input slider to the left, until the brightness looks normal again. Click OK to apply. (see example image below)

5 Finally, the colours do change slightly. So in order to correct this go into the Adjustments menu and select "Hue", simply move the Hue slider left or right until you are satisfied with the result. If it is still not quite right, adjust the lightnes and/or saturation as well. (see example image below)

5 (and a half) for any large specks remaining you can use the "Spot Healing" tool; found in the toolbox (the icon with the plaster/bandaid)

If all has gone well and you have followed the steps, you will have a DIY remastered image.
