Brushes Fixing image with an area of artefactual colour

[Aragorn1976]

Hi, I would like to fix the upper area of the right shoe (see attachment), which has got artefactual colours. Could you please suggest me how to do it? Anything more precise than the clone tool? And if I have to use the clone tool, what kind of pencil would work better? Thanks

 

[IamSam]

For me, the easiest way would be to paint it in with the Brush Tool.

Expand the canvas.
Create a boundary selection with the Pen Tool


Then start painting.


Finished!

Added..........I would Borrow and mask for the sock.

Borrowed by selecting and using Cmd/Cntrl + J to copy to it's own layer.
Move into position with the Move Tool.
Resized using Free Transform.
Then add a layer mask and blend.



Same borrowing techniques for the lower portion of the sock edge.


Finished.

Thanks for your reply. How can I paint and keep the colours of the adjacent part of the picture please? Meanwhile, this is my preliminary result, but I am really bad with the clone tool....I will try to use the spot healing one. If you could please explain how I could paint with the same colours pattern, I would probably be able to fix it!!! Thanks

 

[Aragorn1976]

I regenerated all the missing parts with the clone tool, which is a bit messy

Thanks for your reply. How can I paint and keep the colours of the adjacent part of the picture please?

Sample the colors of the adjacent areas.

If you could please explain how I could paint with the same colours pattern

Nothing special here! Just sample the color from the adjacent areas and simulate/paint the texture..............there's not much texture here so it's not a huge concern.

Yeah.............you need to create guiding selections using the Pen Tool then paint..............this is not the best situation for the Clone Stamp Tool.

You may getaway with it on the upper shoes missing toe section.

[IamSam]

Are you interested in knowing how to repair the green area? This is not a job for the Clone Stamp Tool!

 

[Aragorn1976]

Yes please. could you please show me how to do it and the final result?

 

[Aragorn1976]

This is my result, after some spot cleaning. Not too bad, but far from perfect. Especially the rounded tops, which are quite irregular

 

[IamSam]

Yes please. could you please show me how to do it and the final result?

Sorry..............got busy and have only just found the time to respond.

I first made a selection and copy of the green area of the top shoe.


I then used a Hue & Saturation adjustment layer clipped to the copy to remove the tint.
I also added a Curves adjustment layer clipped to the copy to to adjust the contrast.


Since the selected layer was visible against the white background, I added a layer mask to clean up.
Before layer mask

After layer mask


Next, I mainly used the Brush Tool to paint in the missing area and to remove/blend the "line/edge"


Finished

Looks great!
You need to use the Pen Tool selections I described above to make and constrain any work on the rounded areas.

Hi, I am struggling to constrain my work to any specific areas. Could you please give me more information on the steps to follow? Do I have to select the pen tool, the freeform pen tool, the content-aware tracing tool, or the curvature pen tool? Also, from the tool options, do I need to select shapes, path, or pixels? Finally, once I have created a selection with the pen tool, what should I do to constrain the pen tool to that area? Is there an option for that? Or will the selection automatically constrain the brush tool? Thanks

OK.

I will try.

Do I have to select the pen tool, the freeform pen tool, the content-aware tracing tool, or the curvature pen tool?

I have already answered this question. Please read post #2.............

Create a boundary selection with the Pen Tool

Please read post #7

Yeah.............you need to create guiding selections using the Pen Tool then paint

Also, from the tool options, do I need to select shapes, path, or pixels?

Great question! You should use the "path" setting.

Finally, once I have created a selection with the pen tool, what should I do to constrain the pen tool to that area?

Not sure I understand this question. You would not work within a selection using the Pen Tool. Do you mean the Clone Stamp Tool possibly?

The Pen Tool is used to create the selection. The selection is what constrains or limits an area within which to work.

Here is a rectangle that's missing it's right half. Just like a part of a missing shoe.


I use the Pen Tool set to path to define the area I wish to complete or otherwise work in.


I right click and choose make a selection, no feather, then hit enter.
I now have a selection of the right side of the rectangle.


Now that I have a selection which defines a specific area in which to work, I can use the Brush Tool to brush inside the constrains of the selected area!!!
Here are two brush clicks inside the selection..................note that the brush click stays within the selected area.


Or...........I could just fill the selection in thereby completing the rectangle! Or the shoe!


Once you have made a selection of an area that requires a specific part of it to be constrained, you can use any tool to work within the selected/constrained area.

 

[Aragorn1976]

Ok, everything is clear now, thanks!!!

Another example.

I have this wooden box and my client wants me to remove a part off of the side.
I use my Pen Tool (set to path) do make a selection that defines and constrains the area I want to work in.


I then use the Clone Stamp Tool to remove the part.


It's like coloring inside lines or area! Using this method ensures your work will be contained!

Lots of great detail by @IamSam on a great approach to take. I wanted to provide a slightly different approach for consideration that I have regularly used.

First duplicate the image Layer for now turn off visibility of the duplicated image.

Please ignore the extra black lines. Those were guidelines I inlcuded to help me copy and paste from the screen more consistently and are not part of the image proper.









Now we are adding a Layer Style to the image using the Color Overlay with a white Color and Bend set to White. This will remove the color and only leave the Luminosity:



Here is the resulting image with the Image Style added:



Using the polygon lasso tool, select the off color area. In this case selecting some of the white area above the shoe does not matter. Add the Curves adjustment Layer and then click the icon at the bottom of the Layers Panel (box with circle in the middle) which will turn the selection into a Layer Mask with the Curves Adjustment Layer. I adjusted the Curves Adjustment Layer as shown by changing the black and white point to match the luminosity of the previously colored area to match the rest of the shoe:




The resulting image is shown below with match luminosity yet you still can see a boundary issue.



Now I add a blank Layer above all the Layers and use the Healing Brush along the rough transition area with the resulting image below:



Note that both the interior of the shoe and outside edge match.
Now what we need to do is add back the color and do some correction.

Take the duplicated original image and drag it to the top of the Layer Stack and set the blend mode to color.
Sample the color inside the shoe and brush over the areas that had the green tint and now both the luminosity and now the color is corrected. This salvages the original texture that was in the image as well.
Here is the final image below with the above approach and hope this helps.
