Curves

Previously we learned how to adjust and improve the overall tonal contrast of an image with Levels using the Levels adjustment layer.

The levels tool is good for adjusting the shadows and highlights of a picture, but it is limited in its ability to adjust the mid-tones in a picture. There is only one slider for the gray tones in the levels tool.

When we use Curves we have the ability to adjust many different tones of gray in our image.

Please watch the video below to learn how to locate and use the Curves adjustment layer.


CURVES ASSIGNMENT

Using Curves Adjustment layers, create 3 three variations of an image you have taken.

First crop and De-Saturate the image.

Then make 1 layer a moderate "S" curve. This will give you an evenly toned picture with a moderate range of contrast.

Next make a second layer where you have moved the white and dark gray tone to black.


Next make a third layer where you have moved the black and dark gray tone to white.

Save screen shots of the curves window by one of these 2 ways:
1. use the Snipping tool to capture and paste the Curves window into your post
2. Holding down the alt-print screen key and pasting the image into paint. Do this for each of the Curves variations you make. 

Your Blog post should look like the following:
