Must retouch it !

Move arrow to the right, then move back to left, see first white area, hold Shift + Alt then click to get sample white point
Move the arrow to the left, then move back to the right, see first black area, hold Shift + Alt and click to get sample black point
Open Curve ( Ctrl + M ) set black and white point, Delete layer Threshold
Image >> Adjustment >> Replace Color, click on blue circle, more Saturation
make new layer, Replace color again, but this step, set as I did
then clear the pink circle, keep this circle blue
merge all layer ( Ctrl + Shift + E ), then duplicate layer, add Gaussian Blur filter ( 10 px ) opacity = 20 %
merge all layer again, duplicate, change mode = Multiply 35%
use Elliptical Marquee Tool to create this selection ( it elliptical ) then save selection with "1"
pick Marquee tool, right-click on screen , choose Transform Selection
Go to channel 1, press Delete
Fill blue color, then Gaussian Blur by 2 px
using Dodge and Burn Tool to shading
Unsharp mask ( Filter >> Sharpen >> Unsharp Mask )
at last, use White brush and Clone Stamp to clear dirty stain
Final result !!! and stock picture :) see the difference ?
