Filmamigo,
Your images look ok, some of the better ektar images I have seen, but aside from the blues, it is the reds that get me. Look at that crazy red/orange taxi in your last image. That red looks like my singers red shirt
As for processing, I find that Target does a good enough job for me and when I have a special shot, I will scan it myself and pp it myself, but I prefer to have them good from the get go.
