Apply Unsharp mask Filter – Go to Filter – Sharpen – Unsharp mask and put the following value – Amount 40 and Radius 250 pixels, leave the threshold value to default.These values are not fixed, if your image is of lower resolution, reduce these values. Try with different values.
Now Duplicate the layer. You can do that either by right clicking on the image in the layer pallet and select duplicate layer or press Ctrl+J on your key board.
Now Select the duplicate layer, go to Image – Adjustments – Hue and saturation . Make sure colorize is not selected and put the value of Saturation to –80 (minus 80) and click ok. This will basically remove most colours from your image.
It will look like this.
Change the opacity of this layer (the duplicate layer) to 25% and blending mode to “Overlay”
Now go to Layer menu and select and click on “Merge visible”. You will now have only one layer on your layer pallet.
Now go to Image – Adjustment – Hue and saturation – make sure colorize is not selected and put a value for saturation to +10. and click OK. ( increase or decrease saturation value according to image resolution). Make sure that preview box is checked so that you can see the changes immediately.
