Series 'aurora' image 3

[^^ Other series ^^] 3/12 [== Image index ==]

Green colour component enchanced. Although there can be many colours of auroras, the nitrogen-green are the most common. To enchance the contrast, I brightened the green colour component greatly in this photo, and filtered out other colours, as there was quite bright red-yellow-white background from the city lights.
