timmmay: Can you take a picture and post it? Does it look anything like the picture I took of mine, page 3 of this thread?
Photos aren't turning out too well but I'll try again in natural light. Those shadows you have on the bottom extend about half-way up the screen on mine. This means that when reading the eyes are continually moving between dark and light which is very tiring. If I drop the light down below 16 I cannot see the text at all in those darker spots - they get completely blacked out.
From what I understand those shadow cones along the bottom are normal with the Paperwhite. Dark smudgy shadows higher up and tinges of colour aren't normal but are an issue Amazon has said they are aware of.
