Nice one
Has provided a little more punch to the surrounding halo. If you want to give the dust lane more contrast without sharpening i.e using a HPF or USM which I don't think you need to do as it looks good already, you could try using the multiply blend mode.
- Duplicate the currently layer
- On the new layer, stretch it hard with curves (don't be too concerned about the noise)
- Select the Multiply blend mode. The image will turn rather dark.
- Drop the opacity of the layer, focusing on the dust lanes. Drop to taste where the dust lanes are looking aesthetic (don't worry about the background).
- Create a hide all mask for the new layer and paint the dust lane characteristics. If you're not happy with the contrast, either adjust the layer opacity to suit or alter the brush flow and opacity.
- Blur the mask (not the layer) to provide a smooth contrast enhancement transition.
- Subtlety is the essence.
- Flatten and enjoy.
Cheers
