These photos some are HDR and some are DRI (Digital Range Increase). Both of them are great technique for enhancing sunset photography,as you will hardly get both sky and foreground detail out straight from the camera.
I am a Adelaide,South Australia base amatuer photographer who like to do any kind of photography as long as it is interesting and beautiful in my eyes. I like to do photography because I joined flickr, one of the best photography website in the world. I never ever thought of it would be my favorite hobby someday in my life.
I have heard a lot of people buying expensive camera, lenses, filter etc to do photography. However, from my point of view, being a successful photographer, it is no necessary to have a real expensive equipment; the most expensive tool is actually your eyes – the eyes of beauty. Without the eyes of beauty, a photo that taken from million dollars camera also worth nothing.
