The new Picasa Blog alerted me to a hidden feature - apparently called an Easter Egg (hidden!)
If you edit a picture in Picasa and then go to the 'Effects' tab, hold down Ctrl while you select Graduated Tint...and you will see 'Radial Tint'...oooh!
I've found that this is great for images that have a source of 'light' in them, like the picture above - I tinted the picture with quite a dark blue but positioned the radial cursor over the lantern and then increased the 'feather' effect so that it looks as if the light is being thrown onto the snow.
The second picture was also sharpened to create more of a paper texture to the pic, but that was before I started playing with this new feature!
Picasa is free with the Google Pack download.
