I have recently bought lots of new photo equipment. First, in the beginning of December last year, was the tripod, that I managed to test a bit during some night walks in Patra and the bridge. Later I decided to try long exposure photography and purchased a variable ND2-400 filter. And just recently I have finally decided to upgrade the camera itself to Nikon D90 :-D Nothing really fancy, but even this already 4.5 year old Nikon is a hell of a boost from 10+ year old D70s!
Today a test of all new items: sunset photo from tripod of course, with ND filter on, with some long exposures. First one from D70s, second from my brand new D90.
It is very easy to notice quite disturbing noise on the photo from D70s. Even though in this case the shutter time was 13s (half of what was set in second photo with D90). The main problem with this camera is the sensor itself, as it is old technology CCD sensor that gets warm very fast during long exposures, and was well known for any disadvantages degarding noise.
Second photo is muuuuch better :-D Shutter time 25s! I am very happy with the result! And now, there is much more to crop from as the sensor is not only new technology CMOS, but also twice the size of D70s, with 12MP.
Just in case You haven't recognized, it's sunset from Mpozaitika.
