Photoshop Tutorial-Curves

One of the things I heard when I first received critiques on my photos was that they “needed some pop” or “a bit of curves”. My initial forays into the curves filter in Photoshop intimidated me, but I finally shook myself and made a determined effort. In the following tutorial you will find some easy lessons that will allow you to master this technique.

The Basic Layout

Lets open up a Curves command and get a look at things. You will see a central area divided into squares and intersected with a darker line running from bottom left to top right. This line represents the exposure values in your image, ranging from the darkest values in the lower left to the lightest in the upper right.Move your mouse over your image and you will see that it changes to an eyedropper icon. When you click on your image you will see a dot click on your curves line. This represents the exposure level of the portion of the image you clicked on.
You can can create a waypoint on your line by holding down the ctr key and clicking on a portion of the image. We will deal with these waypoints a bit later.You can move a waypoint by holding your mouse down and moving it, and you can get rid of it by grabbing it with your mouse down and pulling it off just like a cloths peg from a line.Now make a waypoint, and pull it into the areas I have labeled L or D. Again, you can do this by holding your mouse button down on the waypoint and dragging it. If you drag it into the L area, you will see that the corresponding areas in your image will get lighter (Be sure the preview button is checked). Similarly try dragging it into the D portion to make it darker.

The S Curve

The most common use of curves is the S curve. This is a curve which increases contrast which provides the pop to an image. It makes your darks a bit darker and lights a bit lighter, and does it in a graduated way that looks natural. You can make this curve without waypoints but lets add some. Click on your line where it intersects the grid in the lower left and upper right.Pull the lower left down a bit and the upper right up a bit. Check your preview and adjust to suit. That’s it, that’s all there is to it. Click on Image

Curves can be used for many other things including Setting the White and Black Point but the S Curve will give you a great way to give your photos a boost.

Washboard Falls: Ontario Waterfalls

Washboard Falls, Ontario

Upstream from Tiffany Falls, you will find the interesting falls known as Washboard Falls. One look will tell show you it is well named. It was formed like this because the surface it drops over is all equally resistant to erosion. However, to reach it you must make a difficult and potentially dangerous trip upstream from Tiffany Falls.

Rating:

Warning: It can be dangerous to view and photograph waterfalls. The footing can be wet and slippery, and an accidental fall can result in serious injury or death. Note also that many sections of waterfalls are on private property. Please respect these rights.

One of the most popular features on the old version of this site was a Guide to Pelagic Birding which includes items on the basics, a list of operators, and my own modest seabird gallery. I have recently updated it and you can find it at the following link:

Fly Agaric, Amanita muscaria var. guessowii

Fly Agaric, Amanita muscaria var. guessowii

Fly Agaric, Amanita muscaria, is the typical colorful toadstool seen in children’s books. It has some interesting chemical properties as it is both a poison and a hallucinogen. The latter properties were said to give it religious significance to the Koryaks people of eastern Siberia. It should be emphasized that the North American variety doesn’t have the hallucinogen properties but certainly has the poisonous ones. Leave it alone.

This image was taken in Algonquin N.P., a great place to find interesting fungus.
