Create a duplicate layer of your image. Optional: put the layer in a Smart Object, so you can readjust the filter setting later. Change the layer's blend mode to overlay or one of the other overlay blend modes, such as hard light, etc. apply the filter: Other>High Pass. Adjust the radius to get the effect you want. The smaller the radius the more the filter acts like a sharpening filter. The bigger radius, the more the filter starts to to model the spacial features of the image.
