I have been using the Picnik software in flickr.com for quite a while.
And, I love it.
There are so many effects that can be used to make the picture more alive and stand out. Or quickly get some special effects that require hours using Photoshop, rather.
E-5 with Zuiko Digital ED7-14mm F4.0
7mm, f/5.6, 1/1600s, ISO200, -0.3ev
From the original picture, I crop it from 4:3 into 16:9 to give the cinematic effect. Then, changed the tonal and focal impact using the Orton Effect filter and added vignetting to the sides to emphasize more on the central subject.
That's all to it... Well, other than using a super-duper ultra-wide lens, that is!!
