Bump question

[Jpalm]

Really like Twilight!
This is a test scene I downloaded and textured/added lights and made some small additions (rail...)
in Twilight.
Notice the bump of wall on right. The bump it is correct, dark is deep (bump inverted).
In the lower left it appears the opposite.
Part of the wall, as your eye follows from rear of the wall closer to camera seem to change.
Optcal illision? Lighting is the same. Changed the camera angle a bit and it looks fine.

Is the face reversed?
Which render setting is being used?

Looking fantastic, so far.

Face is correct. Bump inverted! Same texture on right wall.
Easy 10- 3 hours, 20 min. Easy 8, too many fire flies
Tried changing light bounce, seems to work but don't like the look.
Thanks for the comment.

It is an optical illusion.
Just keep staring at long enough and it changes.
Scroll the picture up and down a little slowly.
Look down at it the your eye adjust and it stays correct fow awhile.
Funny!

Very good render and very good optical illusion, seems a joke.

Agree, something is wrong! The light from under the table is causing the side close to the light to highlight and the far side to shadow so it's sticking out.

If there is a light off screen causing this it would create a shadow on the chair legs back toward the pool too but that's not visible

I'd fudge it and invert it again just on that side to see what it looks like. Or try zooming on that area to get a better look with less guesses about optical illusions
