Recently shoot a lot of landscape pics and found that lot of dust on the pics. Which is the best way to remove them? I normally don't do post editing....
Since your profile lists Nikon D70 & D200 DSLR as your cameras, then the other alternative is to use dust removal reference file and shoot your images in NEF or RAW format. With dust reference file and NEF file format, you can do dust removal on Nikon CaptureNX software.
If you are using PhotoShop CS2/CS3, there is a tool called the Spot Healing Brush. Click on the brush, set your brush size to slightly bigger than the dust spot and hardness to zero. Click once on the spot and it should disappear. Click again if necessary.
