Photoshop Lightroom 1.0 - Now available
with a Non Destructive Spot Remover
Most of you are probably aware that Lightroom 1.0 has a Remove Spots Tool that has two spot
removing options Cloning and Healing. Every reference I have seen
to it so far though, only talks about removing dust spots that appear
on the sensor of Digital SLRs. Well I may just be lucky but I rarely
have problems with dust spots on the sensor. Probably do to the fact
that over the years I have often been on assignment in such extreme
weather and climate conditions, that I have always been
overly cautious and paranoid about the process of changing lenses. When
I am not on assignment, I also tend to put one lens on the camera and
use that for the entire day, or maybe the week.
So since I couldn't find a recent image that had any dust spots in my
Library, I decided to do a test with irritating real life blemishes on
a photograph. Why not? the principle is the same.
The difference between the cloning and healing tools is that the
cloning tool clones the pixels from one area to another and the healing
tool uses the pixels surrounding the area being healed to make a better
blend. Since the blending process may distort an edge or straight line
near the area being healed it is best to use the cloning tool when
close to an edge and the healing tool the rest of the time.
This is a cropped in section of the original image (zoomed in 1:1) of
water barrels on a Thai fishing boat.
Image by George Mann - Nikon D40 with kit lens.
The pink circle is the area being healed, the white circle is the area
the pixels are being copied from. By dragging on the white circle (with
the mouse) it can be moved to any location and a white line will join
the two circles, release the mouse and the action will take place. hit
the Clear button to reverse the action. The size of the area effected
can be adjusted by dragging on the edge of either circle.
All the circles on this image represent spots that have been removed.
Since this is a non-destructive process, the original RAW image is
never changed and all edits can be cleared or reset at any
time to start over or go for a different result. To change the image
permanently it has to be exported in a different format such as jpeg,
PSD or tiff.
The same image as the last one above but with the Remove Spots Tool
turned off (if I turned the Remove Spots Tool back on, all the circles
would return). More work could be done but this version is obviously a
lot cleaner than the original image.
