This is a follow up to the SIG notes in the May AUSOM News magazine.

In the May SIG
(1) We began with a demo of what you can do with some of the NIK effects available for free from Google (https://www.google.com/nikcollection/).

(2) Next we looked at how to use Adobe Camera Raw (ACR) to make initial adjustments to an image before bringing it into PS or PE. We looked at how to use either Lightroom, PS, or PE to open an image in ACR.

(3) Then there was a demo of using the basic editing page in ACR to enhance an image.

(4) Lastly, we looked at how to make a selection and then what to do with it once we had selected it.

All of this is being written before the actual SIG on Saturday. It could turn out that with the AGM running over time that we only cover a small part of what I hoped to get through. If that is the case, then we will continue on with it next month.

Part 1 – Using the NIK collection (free from Google)
After downloading the 430 MB file and waiting 15 minutes for it to finish downloading, your next step is click on the file to open it.

(1) Go to https://www.google.com/nikcollection/ and click on the text that says MAC.

For Mac users, click on the text that says MAC, decide where to save it, and sit back and wait while it downloads.

(2) Here is how it looks in my browser (Google Chrome).

Depending on your browser, when the download is complete, click on the file.

(3) A small dialogue box pops up and asks you “Do you trust this computer?” Say a silent prayer and then click “Yes I do!” And remember what happened the last time that you said “I do.”

(4) Open one of your images in Photoshop.

(5) Click on Layer/Duplicate Layer. This is one way to preserve the original file in case you forgot to do the usual (create a working copy of the file and rename it WIP for work in progress.

(6) Click on Filter/NIK Collection/Analog Efex Pro 2. The cat tail that you see is that of Ottalie, who belongs to the previous Photoshop guru.

Click on image to see in full size.

(7) For today, we are only going to pick one of the ready made presets to try. And now we’ll try the one marked Camera 1 on the left hand side of the image below. Scroll down through the other six or seven presets to see if there is one that you prefer. I’m going to try the one titled “I’m feeling lucky.”

Try the “I’m feeling lucky!” option.

(8) Now is a good time to go and get a cup of coffee while the new look image is rendered.

(9) I don’t know why, but it seems to work better if you first click on the Brush button, then wait until the image is rendered, and then click on the Apply button. Otherwise, it seems to just grind to a halt on my computer.

Click on the Brush Button. Have a cuppa while it renders the image. Then click on the Apply button.

(10) That is as far as we will go with the NIK collection for this month. It is over to you to have a play with the different modules and see what you come up with. There is a video that gives a good explanation at http://greylearning.com/courses/nik-bundle.

Part 2 – Intro to Selections
There will be times that you might want to change only part of a snapshot. This is where knowing how to make a selection and how to use it can be helpful. Here are the following websites that I have shamelessly used in putting these notes together:

  1. http://www.photoshopessentials.com/basics/selections/why-make-selections/
  2. http://www.photoshopessentials.com/basics/selections/rectangular-marquee-tool/
  3. http://www.photoshopessentials.com/basics/selections/elliptical-marquee-tool/
  4. http://www.photoshopessentials.com/basics/selections/lasso-tool/
  5. http://www.photoshopessentials.com/basics/selections/polygonal-lasso-tool/.

What I would like to do here is show you how to make a selection and then to use it for a particular purpose. So let’s look at a few.

Painting a piece of fruit a different colour from the others around it.
(1) Open up the image shown here by doing a copy and save of the image to your computer.

(2) Let’s change the colour of the apple on the right to green.

(3) Open the photo in PS/PE.

(4) Duplicate the layer.

(5) Click on the Quick Selection Tool in the toolbar on the left hand side. If you get part of the selection in the wrong place, then hold down the Alt (Option key) key and make another selection. This actually subtracts from the original selection.

Click on the Quick Selection Tool

(6) Press B to bring up your brush tool so that we can paint the apple.

Press B for Brush Tool. Settings are Normal Mode and 100% for Opacity and Flow. Use square bracket keys to change size of the brush.

(7) Change the foreground colour to a nice green.  The selection outline means that we are only painting in the selected area

The selection means that you will only paint inside the selection. If you go over te edges, it will not show up.

 

(8) If I lower the opacity to say 20%, then I am able to get a feathered outline between the red and green colors. Let me know if you see an apple that looks like this!

Image 11 - green and red apple

Use a 20% opacity setting and several strokes of your brush to get a smooth blend from the green into the red.

(9) Done! Pat your self on the back.

Summary for May SIG
We have looked at how to download, install and use the NIK collection.

In the remaining time, we have made a start on Selection tools, and one way that they may be used.

For the June SIG
We will look in detail at the selection tools and different ways that they may be used.
