Google has been championing every web based but one of the most successful tool is Picasa, which is a downloaded application tool. So, in order to do everything online, they acquired a small 20-person company Bitnik, Inc that developed Picnik.
What is Picnik? It is an easy to use and powerful set of flash based photo editing tools for editing, sharing and even printing images using any Internet browser (which is how Google Chrome OS would like it to be) hence you can edit photos wherever and whenever you like. It is also integrated with a wide variety of websites like Yahoo! Flickr, Google’s Picasa Web Albums and Photobucket. It even has a Google Chrome extension for pulling online images into its editor that is capable of the basic editing tools such as cropping, rotating, resizing, red-eye removal and other standard special effects such as sharpening.
It even has “Curves” which is used to highlight different colours and shadows. From initial usage, it is FAST! for a web based solution. You can find out more about them at www.picnik.com.
