Oh wow.. first of all Ln X that is a great picture, seems a little glossed up to great effect. Perfect Janeway expression.
I just paused the DVD I was running on my computer (using Windows Media), pressed the print screen keyboard command, loaded up the paint program, cropped the image and reduced the cropped image's size to 63% of original. By reducing the image size you improve the resolution, but I did nothing else to the image.
I think season 4 and 5 Janeway looked the best, because she had that awesome bob and still retained her trimness from the earlier seasons. Not that I minded when Janeway put on a little spare in seasons 6 and 7...
