Ahaaa... I see now... ND filters... Did a quick search on it and I'm quite amazed at the results. Don't mind me... I'm just a terrible noob at this. I much preferred product/closeup/abstract shots... things that basically don't need any particular filter for that matter.
Starburst - comes from small apertures with long exposures. Noted.
I was planning on capturing the light from the buildings and the roads in particular, so I wasn't hoping for, or at least, aiming for a Starburst effect... seems that I stumbled upon a hidden treasure or something
Thanks for the heads up.
Anyone can recommend me any other filters/steps to really saturate the sunrise colors? Or should CPL do the job as well?
