Description

Not comlletely happy with the color of this image, but hey, that's less than half an hour of integration! So, overall, not only will try longer in the nexts weeks/months, but also I must say that the image turned out to be a lot better than expected!

Constructive criticism, comments and suggestions are more than welcome in the comments section.

Taken from Rural Skies (Bortle 3-4), from Cristina, MG, Brazil (22ºS latitude). Thanks for looking.

*Revision -B- is a simple crop of the galaxies region, based on -A- version*

*Revision -C- features improved color correction over -A-, being further processed in PS*

*Revision -D- is a a star-shrunk version of -C-, and a bit more contrast/curves enhanced. To me, it looks overprocessed, but you can see more details.... What do you think?*

*Revision -E- adds subtle processing to -C- in Google's Nik Collection's Color Efex, using the Detail Extractor tool. The effect, subtle at 100%, is even less apparent in the full size image, but, here it is*
