Resizing Images

Thanks apaflo, that helps clear things up a little (unlike other two replies). I've actually started doing a USM with radius 0.5-1.0, value 3.0-5.0 and threshold 0-5 and then a scale with cubic interpolation, which gives me pictures similar to the output of IE, but without the aliasing and moire.

Still, it seems odd to me. There must be millions of people, all shooting like me in JPG and viewing their pictures in Windows Photo Viewer and being a little disappointed that they've taken another soft photo, when actually they haven't? Or am I kidding myself? It just seems so odd that by default cameras should produce pictures that look bad on screen (Picasa seems to use the same method as WPV, as presumably so do others), even if it's the software's fault.

Personally, I like shooting in JPG because I don't want to spend time manually processing my pictures. I understand the principles of doing so, and completely understand why most do, but I find I spend too long over each picture endlessly fiddling. I would rather not even have to do this sharpening, tbh, it feels like I've failed to get the picture, or done something wrong, and now I'm trying to cover it up.
