Autumn forest pictures are popular to create a nature wallpaper. Such as this one, an awesome high resolution fall picture by Aleksei Malygin with high quality result. Basically, the original photo of this wallpaper was in 3750×2500 pixels. But it was adjusted into 4K resolution with 3840×2160 pixels. Aleksei Malygin used a camera of Canon EOS 6D with several settings such as: f/10 1/125 17mm ISO400.
I use this wallpaper as one of the best beautiful nature wallpaper with big size. Feel free to collect by downloading it in original size. You can also get another wallpapers with big size from this site by visiting our gallery.
