Clearing canvas texture from photo of artwork

[dmaarie]

Thank you to you both, though I was looking to keep the uneven layer of grey paint. Not a solid grey for the background. Basically, the exact kind of grey background i painted but no texture haha seeming to be unachievable.

Maybe Ill just create prints of the figures with different coloured solid backgrounds instead. Not the end of the world.

Thanks for the help.
