I have the latest version of DPP (digita photo professional). I reduce the picture size to 800x533, save in 16bit tif, sharpen it and save again in lowest quality jpeg, thats all. Make sure you have a tiff image or you will get very bad jpegartifacts from saving injpegtwice. You always have to sharpen the down-rezed version of the picture or it willlook soft.
