Everything is good in moderation and with good planning
.
Photography is art ... a lot of people forget the roots of photography - its basically a bastard child of art
.
Now, there are different levels of photography ... as I call them:
"Pure photography" ... what you click is what you get ... you modify anything, you loose
.
"Normal photography" ... by today's standards
... with slight post-processing to help with framing and color balance.
"Art photography" ... same as above but with additional changes to create a vintage mood or something different - like borders, scratches etc ...
"Photography as a background for art" ... taken to extreme ... you use the image as a background to create something completely futuristic ... or magical, depending on your vision; like taking picture of a landscape and then in Photoshop paint (actually paint not paste things) a futuristic city ...
Now, of what you want to be part of ... is up to you as a photographer ... or artist
.
Color selections are great ways to emphasise something. I like them as long they have sense and they send a message ...
