This is a 'clean' image with less variation in the RGB channels than
|So I think if we replaced the Blue channel with the Red
on, we would marginally (1/6th) improve the detail in the boats and also
darken the sky. In addition a small contrast curve in the Green
channel would bring out some more detail at the expense of the left
foreground and church.
Now I just do not like the idea of doing these corrections blind,
i.e. without seeing the b&W image as I make the adjustments.
So I had the idea of creating an additional view
(Window>Documents>New Window - in Photoshop) and setting that view
to Proof Colors with a profile of Gray Gamma 2.2.
Here is a screen shot of this setup
Note that the b&w image is shown as Proof and so
when you de-saturate the image, it will slightly change - which is very irritating
after all ones work when watching the corrections! The solution to
this problem is to convert rather than de-saturate
(Image>Mode>Convert to Profile... and then select Gray Gamma
2.2). So here it is...
|At last I am now feeling happier about converting to
b&w and being able to see what I'm doing.
An alternative, if one does not want to view the coloured version
while correcting, is to add a White background layer above the
Luminosity layer and then de-saturating will be equivalent to the view
