Those pictures really do show what the camera is capable of and the definition is really good in the 5 Euro note.
What camera app did you use to take those pictures weckl.
I remember I used a mix of camera apps , but mainly Zoom FX was used in all the pictures. The cool HDR picture was done with Camera Pro HDR.
I recommend you also Scalado Album to use as gallery . I found it more quick and responsibe than stock gallery.
