while the Samsung Galaxy Note 5 produced a very light blue sky.
The images from the Note 5 has a consistent gray tinge to them
while those from the iPad look more natural and clearer too.
The iPad Mini 2 rear camera can't be adjusted
so it has automatic settings
unlike the Samsung Galaxy Note 5
which can be adjusted depending on the photographer's preferred settings.
The Note 5 has a more advanced camera
but maybe it wasn't adjusted to the right settings
when the images were taken.
