Surface homogenization

Hi everyone, I mostly take architectural photographs and I regularly stumble upon one problem when I have to deal with with wall surfaces that are not uniform due to aging, tags, moisture, cracks...

On the picture below you can see what I am talking about on the red surface, old tags, new tags, moisture, dog pee. Usually I deal with native Photoshop tools as healing brush, patch but here, and particularly on the "washed out white surface", it is difficult to obtain a nice result with those tools.

I also tried to apply a red layer and I have tested different fusion modes but still with no success.

Any idea on how to deal with this kind of situation and how to uniformise the surface and at the same time to conserve the "grain" of the material and the original lighting ?

Thanks a lot !

Any kind of FS should work.

Re: Surface homogenization

If the blemishes are just a few pixels across, cloning may work. It requires some judgement. For larger ones, I would just burn and dodge things to a point where they look right. If they're significant in size, I might rebuild the area. This involves copying over good pieces, then applying burn and dodge work to ensure it blends seamlessly.

I would typically use some kind of sanity check to spot any points of discontinuity. This can be accomplished with what people often refer to as "solar curves." Overall it's tedious work, but it's not very difficult.

I think the only reason you're having trouble is due to poor technique. It's common, and it's an easy problem to solve. It will also feel satisfying when you no longer have to speculate on whether an approach might work.
