Edit / tweak elliptical marquee selection

[Matthew]

I am trying to make a neat cut out of this circular painting. The painting is not quite a perfect circle. Is there a way to tweak an elliptical marquee selection and put the painting onto a white or transparent layer? Thank you, Matthew

You can use the pen tool

Hi Matthew, 

 

I would advise taking Depa's advice to use the Pen Tool. It will allow you to draw around the circle using nodes and then towards the top left of the app you will have the option to convert the pen path to a selection :)
