Remove person in background

[solley]

Hello Damien,

I would like to remove the guy in the background (light blue suit and yellow tie). I've asked him to move to the side couple of times but he was ignorant and stayed there.
I've tried unsuccessful Quick selection and Fill Content-aware. 
This is a dear photo of my husband and his colleges.

Have you tried copying and flipping the wall/columns from the other side?  That seems like the most likely solution.

[solley]

I haven't. Thanks for the idea! Will try it later even though I'm not quite sure how to do it.

Well, I guess it would be like this eye flip, but on a grander scale.

Damien, it is working amazing. I would need further advice about the halo around the man's arm and double railing.

There's no "trick" to that - just really careful masking.  Generally, for this kind of work, I zoom in to about 400%, and use a 5-6px brush.  Oh, and the Shift key is vital.

400% zoom in + 5px brush + shift key = miracle 
Thank you Damien!

railing - "careful masking" doesn't help. I get either the guy's leg and shoe to the double railing. I thought of using the same method.
I have to start over anyway. Didn't notice a brick shifting above. Will post again tomorrow.

Some cloning will inevitably be necessary as well.
