Philips 9 digital frame review:

 

To start: All Philips digital picture frames have an extreme high pixel amount per square inch. This gives a very good resolution, and that is visible!

The 2 most used frame sizes are the 7 Inch and the 9 Inch.
Although on both the pictures look very sharp, the viewing angle on the 9 inch is much better. This actually really nice because you do not have to sit right in front of it to have a sharp vision. 

But of course the main difference between these 2 is...  
the intern Smart Album in the 9 inch version!
This helps you to change the photos almost like a mini photoshop; for example you can turn, cut, zoom and change the colors to greyscale. This works through a simple option, the Wizard PhotoEffect. You can change the pictures exactly the way you like it!
