| Comment : | Compare this photo with a Nikon D800 with the one below taken with a Canon 6D. Looks like the Canon is much better, on the Nikon photo there is no stars in the background, the famous star eater, or ? I don't think so because it's only this photo that show this. If I increase the contrast there are a lot of hot pixels. Just one of many photos I take yo compare with other equipment. Note: Nikon is set to 400iso, Canon set to 1600iso. |
