Help with removing person in photo

Question

I'm fairly new to photoshop and am familiar with removing objects/content aware.In the link im trying to remove the person with the hat on and fix whats left over to make it look like water is there.Mostly though having trouble removing the lower part of the guy between his arms and keeping the water and plants there.

So my question would be what is the cleanest/pro way of removing the person and keeping it looking like the water and weeds are still there?thanks for the help.

Answer 1

thank you Cadogan, I am glad you like the results. Here are a few images that might help:
this was the plane I made inside vanishing point, the idea is to ignore everything else and just try to focus at the river perspective. If your plane turns red or yellow you have an invalid plane that vanishing point can't really understand. play around with settings until you get a blue plane. once the plane looks good, hit ok to exit vanishing point.
create a new layer and go back to vanishing point, clone stamp some water from the top right area, until you get something like this:
as you can see I am overlapping his arms a lot, and cleaning up unwanted parts later by loading up the mask. play around with Levels to lighten up the water a bit and it should blend pretty well.
finally, add a new layer to clone stamp the weeds, these were the general areas I used:
please post again if you have any question, have fun!
