Smooth a wall

[meris]

here's a 700x700

I have a plaster wall that has gone wobbly as time passed. There are places where it's not smooth, and I see grooves like this. How would I fix it? Because it's not a simple gradient.

 

I've tried the patch tool, sometimes it works.

 

Sometimes the edges of the patching gets a halo, and I duno why.

 

Sometimes maybe from the noise, I get posterisation of the area I patched.

May I see the whole photo as well, for context?

This is the wall, a four way cyc

The light stripe you see in the top left is actually from a fold in the plaster

The around corners have the biggest problems with random scratches and stuff

I also very find it very hard to edit this wall because it's hard to see all the issues after staring at grey for a while. I have to come back to it several times over several days

 

Because it's a small space I can't have people far enough away from the back to hide the issues

Ok, thanks.

And may I see an actual photo you've taken (with a subject in it), before and after your wall fix?

[meris]

Sometimes these waves come if I edit then see another issue and edit again.

Sometimes the halo appears and I keep patching the edges of it and see if it goes before I reach the subjects.

I'm thinking make separate gradients and blend them into each area. What do you think? Like the blanket fade but not quite

[Damien Symonds]

So you want to keep the box shape of the background?

[meris]

Not especially, but when you can see the ground or sidewalls I want it to look like a real background and not something I dropped in.

[Damien Symonds]

Ok.

I'd asked for two versions of the photo - both before and after your fix.  That would really help me if you could provide it, thanks.

[meris]

There's no after because I'm not happy with anything other than full replacement of bg where it's a half body

 

All the parts in the last post are from attempts to change it which didn't work because of the artefacts you can see

[Damien Symonds]

The only way to do this properly is to replace the background altogether.  https://www.damiensymonds.net/preventing-banding-in-backdrops/

[Damien Symonds]

Some other recent examples here, here and here.

[meris]

Using the dither  option  on the gradient, how do I combine that with the noise layer? Should I use both or just one or the other? Because I will apply the noise layer to parts that I do not change

[Damien Symonds]

The noise layer is clipped to the gradient layer.  Therefore, it is automatically applied to the parts you change.

How did you go with yours?  What did you think of mine?

@tracyandrade, this one is relevant to you.

[meris]

The edit is good, and faster than patching.

I'm just wondering about how to fix my wall. No point having a cyc if you have to edit each one.

Of course I"ll get it smoothed, but is there a min. radius to avoid reflections?

What's a cyc?

[meris]

cyclorama wall

[Damien Symonds]

Can you link me to images that other people have produced, using a cyclorama wall?  Yours seriously just looks like a box.

[meris]

I don't have the space. If I had 5x the width and depth it'd look like

It should kinda just fade off and not draw attention

[Damien Symonds]

Right, that's exactly what I thought.

You have to replace your background every single time. There is no other way.

[Damien Symonds]

Now that I've seen what you like, I've had another go:

[meris]

Looks good. How much of the back was replaced?

[Damien Symonds]

All of it, of course.  Hold on, I'll upload the PSD ...
