Using Photoshop, I duplicated the Background layer and used the Dust & Scratches filter, with a radius of 2 pixels, to remove the noise from the duplicate. I then used a white layer mask on the duplicate and applied a white to black gradient (top to bottom) on it so the image would be blurred much more on top than on the bottom. This process pretty much blurred out the white water drops. The droplets can be brought back into the image by selecting them (using Select>Color Range) from the original Background layer. You can then apply that selection to the layer mask and paint with black to bring the drops back up (so to speak) from the lower layer. My gradient wasn't perfect so I finished up with a little selective sharpening to bring back more of the sharpness in the foreground area.
It probably sounds complicated but actually it went pretty quickly. A link to the current image.
