Seeking some tips on using Prizmo

Do you have any tips on using prizmo? I've downloaded the app as it's been recommended by applevis, but text is either missing or garbled nonsense each time I've tried yo take a shot of text and have VO read it to me.
Any help / instructions would be greatly appreciated.

The Giraffe stand is useful if you can't see because it lines the camera up for taking photos of letters and magazines. I use the quick capture option.
