Isolate It! Yes that’s right this action will isolate light from dark colors and leave original image untouched. Isolate fire, smoke, clouds, objects etc. with this one simple photoshop action.
I will be honest here, to get great isolations you will have to have a great image for it (Image needs to have a clear difference in light and dark colors) if the image not so great you might have to do some brushing yourself. I used three different images for preview examples; all three came out great no additional editing was needed. This Action is great not only for isolations; it is also great for photo editing, especially night photography.
