Yes, noise is problem sometimes, but sometimes it can be good, i think on some photos noise gives little bit older look..not everything has to be perfect, right? :-)
Thank you , John, for your suggestion. My camera , its small one(Kodak Z650),as all you ready know, and the distance to the factory its about one ,ore, two kilometres! And as a amator photografer tha I am, I welcome critiques and suggestions from all of you, thats way I am here.
It's a very interesting shot Ambenis, I think you could use less ISO speed for that time to have less noise as there are some of red and green spots especialy at the middle sky area, anyway it is not something we can do about... I mean noise in long exposure is something that we cannot erase from our photos... I have the same problem and I know a friend that he has a much more expensive camera that we have BUT again he has noise problem... good one. be well!
