Photoshop SIG for September, 2016

Photoshop Skills(1) (1)

Introduction
There are several different methods that may be used to enhance your photos. This method discussed last month and this month consists of the following order of steps:
(1) Shadow and Highlights tool,
(2) Levels tool
(3) Colour Balance tool
(4) Hue and Saturation tool
(5) Vibrance tool

Introduction
This month’s discussion will be about tools (3), (4) and (5). These are tools in PS/PE that can be used to enhance or correct faults with an image.

Breaking News
There have been requests in both the Photoshop and Photography SIGS to spend some time on an introduction to Lightroom.

This will be done in the first six months of 2017 during the Photography SIG. We are looking for interested parties to run the Intro to Lightroom sessions. Please share your expertise with us.

The Colour Balance Tool
Let’s start with a short video to get the overall picture (Very punny, Bill.)


(1) Open up you image in PS/PE.
(2) Duplicate the layer using Control + J as a keyboard short cut. I then set the Blend Mode to Multiply to darken the image. I then adjusted the Opacity down a tad
(3) Click on Layer/New Adjustment Layer/Color Balance. Or click on the icon at the bottom of the Layers Tool as shown here:

(4) Here is the tool box that comes up in CS6.

Did you notice the reflection of the handsome photographer?

(5) Now it is simply  a case of experimenting with the sliders for the different colours with the shadows, midtones and highlights.
(6) Best to leave the  Preserve Luminosity box ticked. It lightens or darkens the colour so that after changing the colours, the apparent brightness is still the same.

Here is the final version.

Well, that was a brief discussion of the Colour Balance tool. Let’s move on to the Hue/Saturation tool.

The Hue/Saturation tool.
Here is a good explanation of why we need something besides just the colour balance tool.

“So far I hope I’ve berated the point that Color Balance is just what name implies, a fine balance. It should be apparent by now that most color adjustments made to the image will directly affect the rest of the color in the image. For example, you can’t seem to increase the amount of Green without decreasing the Magenta in an image.

This problem is called “crossover,” and can be very frustrating if, for instance, you like the amount of Magenta in an image, but want to increase the Green.

Photoshop has two powerful tools that will aid you in this battle, and will decrease the amount of crossover. They are the Hue/Saturation tool . . .” (Source: http://www.bairarteditions.com/pages/tutorials/photoshop/cbhuesat.html)

Here is a video that shows us how to use the Hue/Saturation Tool like a delicate scalpel rather than a sledge hammer.

Well, I don’t think that I can do any better than that video for a good explanation. So let’s take a photo and give it a try.
(1) Open up a snapshot that you want to enhance,

Note: This is a camera raw file that I am using. It opens up in in Adobe Camera Raw. I have chosen Shade as the White Balance and then clicked on the Auto below the top two sliders. This gives me a good place to start. Looks like this:

Click on image to in full size. You may be wondering, “What is that?” A shot of a rock on the beach at low tide  with bits of sea weed on it. Followed by, “Why would you take a photo of that?”

(2) Control + J to duplicate it.
(3) Play with the Blend modes and Opacity controls for a bit. I settled for Colour Burn blend mode and 100% opacity.
(4) Save as a .psd version 1 so that you can come back to this as a starting point.
(5) Press control + 0 (zero) to fill your screen.
(6) Click on Layer/New Adjustment Layer/Hue/Saturation.

Conclusion
That’s as far as we got in the last September SIG. That leaves us the Vibrance tool to start the discussion for the October SIG.

That’s all, folks!
