I discovered that the photo app Living Planet was going free today so couldn't resist downloading it to see how good it was. The app is by Samer Azzam who has also developed Stackables, another photo app that may well enter my 'A' list.
I think this app will definitely have a place on my iPad to use occasionally when I want to use the special effect that it produces which is putting photos in a circle. Here is what I came up with. It was a photo of the main city area of Hong Kong Island from my apartment in MidLevels. In iColorama I blended it with a sunset picture of the Big Buddha (which I had created earlier in Superimpose) and added some text.
