I'm no professional photographer or developer, but still, this is unbelievably good for 99 cents. I must admit, seeing the start up screen with no tools, instructing me to drag and drop an image into the app, I wasn't expecting much, but I was wrong. Once you do that, a reassuring number of tools and options then pop up enabling you to fine tune your image in a number of ways. The end result is, I have to say, very good.
I have so many of these quality one trick ponies in the hope of achieving a cheaper and faster replacement for Photoshop - its apps like this that justify that belief. The general quality of the end result is such that I even go to his type of software before Pixelmator, due to the amount of time it saves.
Seeing as its the only place you can purchase Big Aperture, the App Store is evidently relevant to this software. I'm not an App Store "believer" and for me it will never replace purchasing software through Macupdate or from the developer direct, but considering that software like this is now available when it wasn't before (well, not for 99 cents) as a result of the App Store, I can now for the first time, start to see the App Store's value.
