I used the CamApp example, changed it according the guide in the forum to make it work with the old n6600 camera plugin. Then I made some handmade modification (path and imagenames, a timer). It worked without a flaw.
Now I installed the same program on the N70. It worked without any error messages but the image quality is lower (not by much but visibly) than the quality with the built-in camera app or even with python. I don't know what causes this.
Anyone willing to help me to send the code and look over it?
