-> blending both sides of a scratch?

[Steve JORDI]

Hi,
I have a picture that was scanned from a magazine page that was folded
in four.
I then have a vertical blank line (the fold) on the image.
Any way to automatically fix this?

Like the heal tool? Select the rectangle region containing the fold
scratch and have it automatically apply kind of "stamp" to it using
both sides of the scracth as a median?
Using the stamp tool takes a reference on one point the user
specifies.
I was wondering whether a tool was able to use both sides of a scratch
and automatically calculate a median pixel value (color, intensity,
etc) to mask the scratch?

Thanks for any tip

Sincerely,

^^^^^^^^^^^^^^^^^^^
I doubt that a "heal" tool can do this automatically. At least, I don't
know of any. If such a tool exists, it is certain to be less effective than
what you can do by the use of the clone tool and a little patience. In some
areas you can simply clone in the tone from both sides of the fold.
Anyplace that a line or other image crosses the fold, you should clone it in
by moving along the line (rather than perpendicular to the fold.) If there
are patterns within the image, sometimes you can copy an element of the
pattern and slip it into position in a separate layer. An example would be
something like a cyclone fence or patterned wallpaper.

This is the kind of challenge that makes Photoshop fun. Good luck.

I've never quite understood the difference between the Healing Tool and the
Clone Tool (Rubber Stamp), which is what I've always used. I just played a
bit with the Healing Tool and was able to remove a figure standing in the
middle of a street rather easily, reproducing the curb element and the
traffic-lane stripes with nearly no effort.

I don't know of a tool that can sample two areas at once. Maybe someone with
more experience can enlighten both of us on the advantages of the Healing
Tool over the Clone Tool. Or let us both know about sampling from two areas
for blending.

The clone tool allows you to choose an area and paste it over the area you
want to fix. The healing tool chooses the area surrounding that which you
want to fix, and replaces whatever is inside the circle. They may appear to
do the same thing, but you will find a difference if you try to use the
healing tool right next to a detail you are keeping. It will replace the
area inside the circle with
some of that detail, which can make kind of a mess.

Steve, if you drag the healing tool along a fold, it will in fact sample
both sides and replace the fold with an average of the two. This is fine if
the fold is in a plain area, like a cloudless sky. If the fold goes through
an area with detail, it will put some combination of that detail across the
fold, which probably won't work for you.

Thanks. It's so obvious once you know it! :)

Thanks all for your help.
It's a bit clearer in my mind now and I will try the heal solution.
If not happy with the result, I'll go with good old stamp ! :-)
