Sorry, Im not a professional photographer so I cant give you a review about pixels and such. I do digital scrapbooking and this app is the absolute best for making my photos perfect for scrapping. I use the function that will clip out the people or person that I want so I dont have all that messy background. Then I can use the clipped image and add background "paper" and objects. Its easy and fun for my purposes.
