 | Sometimes the most
subtle differences in the way you process an image using photoshop
can have some dramatic affects on the final image. Here is another
saturation technique that allows you more control, and uses the LAB
mode once again. |
 | We’re going to
take this image of an old 1860’s manure spreader and make a
subtle change to the grass and sky to add more depth and contrast. |
 | First
we need to change from RGB and convert to LAB mode. |
 | 2. Then we going to bring up the
curves dialogue box by hitting ctrl + M. 3. Next we want to choose the “a”
channel. |
 | 4. Make the grid squares smaller in the
curves dialogue box by Alt + clicking anywhere on the grid. |
 5. While in the “a” channel, click
and hold down the point at the top right most part of the grid. While
still holding down the mouse, drag it two squares of the grid to the
left as demonstrated in the image (right) | Grab the lower left corner point and
drag it two squares right.
6. Repeat the procedure in channel
“b”.
Covert your image back to RGB and
you’re done!
Note adjusting the points right and
left give you control over the colors. Practice and experiment using
this method, and you will be surprised at the results you can
achieve.
