I'm pretty sure there is a solution somewhere out there, but I haven't find the right keywords for this problem. I'm not a graphics person just I'd like to remove the background from this image with PhotoShop:
This looks very nice on a white background, but I want to put this onto a black background and it's tricky as it has some "colorful" shadow. I used the Magic Wand to select the object, then inverted the selection and removed the background. Kind-of-works, but if I zoom in there are some problems on the object's edge:
I know I can do a contracted modify of selection, by n pixels, but it doesn't seem realistic if I just remove 1 pixel from the selection:
I'm not limited to use more colors, end design shall be in PNG (so can have transparency too).
I need some nice smooth edges without that background shadow, because I want this object to look good in front of both white and black background.
How can I achieve that?
