Picasa provides you with the editing tools you need to fix common problems and create unique effects in your photos. Double-click the photo you'd like to edit and use the editing tabs to the left:

	Basic Fixes: Make simple fixes to your photos. Fixes range from removing red-eye to cropping photos to one-click fixes for color and contrast.
	Tuning: Use these advanced editing features to fix contrast and remove color cast. Adjust shadows and highlights to add some dimension to your photos or brighten up the foreground with fill light to salvage otherwise dark photos.
	Effects: Choose from 12 effects, ranging from simple filters such as black and white coloring and sharpening to more advanced photographic filters.
	Picnik Effects: Editing tools powered by the good people at Picnik. We've built two tabs worth of Picnik effects - like Vignette, Orton-ish, Cross Process, and Comic Book - directly into the Picasa software.
