The OpenCamera port has two known major problems:
- the noise reduction algorithm is not very sophisticated and allows the user just to select “a level of blurriness” he can still accept
- the algorithm for finding and sharpening edges creates artificial bright structures which are not in the original picture
Both effects are to be seen in your first picture. If you’re not sure about the second one have a look
- at the white body under the black collar of the magpie or
- at the left side of the magpie’s tail or
- at the right side of it’s head or
- at the upper and the bottom side of that black branch going from the tree to the left.
In many cases you get better results using another camera app.
