I have a photograph of an object shot on a plinth.
The floor the plinth is standing on and the wall behind it are both visible.
Behind the plinth, the line where the wall meets the floor is visible.
This (horizon line - for want of a better term) line isn't straight - it slopes very slightly downwards to the left - and I want to make it stright using Photoshop.
What is my best way of doing this? i.e. which tools should I be using?
Thanks.
