Lesson 1: Downloading Images and Opening them in Photoshop

To download,

1. create a new folder on your desktop and name it "photoshop lessons" - this is where you will put your photoshop lesson files.

2. Click on Image 1: Sunset and a new window will appear with a [flawed] image of a sunset in Jasper, Alberta

3. Click and hold on the image [right click for windows machines] and a dialogue box will appear.

4. Select the option "Download Image to Disk" and direct the file to your "photoshop lessons" folder.

5. Do the same for Image 2: Captain Cat.

6. Start up your photoshop software

7. FILE MENU -> OPEN [this notation means go to the file menu and select open]. A dialogue box appears. Direct it to your "photoshop lessons" folder and select the first file that you downloaded "sunset.jpg".

8. Follow the same procedure to open the image "captaincat.jpg".

Okay, you should have two images downloaded and opened in photoshop. We're ready to go


Lesson 2: Assessing an Image

The start of any image work in photoshop is the assessment. What is it that you want to do with the image.

First assess 'captain cat'. What are its flaws, things you'd want to fix if you could take the shot over again [and the cat would only hold still]? Make a list.

If you'd like to see my list, click 'flaws-captain cat'.

Next assess 'sunset'. What are it's flaws? Make a list.

If you'd like to see my list, click 'flaws-sunset'.

Then go on to Lesson 3 and we'll start fixing things.

Lesson 3: Cropping and/or resizing the image

Let's crop Captain Cat to create a better image. For now forget that the horizon line isn't quite straight. We'll simply crop out the bad or distracting parts of the original image and leave in the desirable parts. After you crop it, if you want to see how I cropped it, click: Ray's Captain Cat Crop.

I am now going to direct you to using some of the photoshop TOOLS. The tool bar is on the left by default. So that you know what tool I'm talking about, click on : Photoshop Tool Bar and you will get a new window. Make this window smaller so that you can see it while you read this present window and leave it there for future reference.

There are two methods of cropping, free and fixed proportions.

Method 1: free height to width proportions

This method produces an image that sets no constraints on the height and width of the image. You can crop a square image or any sort of rectangle.

Click on the Crop Tool [if you can't find it, open the "photoshop tool bar" image or look at the image below.
Make sure that the width and height settings are blank. If they are not blank as in the example below, move your cursor along each and delete the settings.
Move cursor to image, click and drag, then release
You don't have to make the perfect crop the first time through. You can change the shape of the rectangle once you've put it on the image. I usually start with a small rectangle and then ...
Click on and use small squares to change the image until the desired crop is obtained
Click on crop tool


--------------------------------------------------------------------------------


Note: When you've rotated an image, you will have solid colors where the image has rotated away from the margins. Thus, your crop tool will have to fit withing those rotated boundaries and you will find that you will always have lost some of the original image. Such is life ... next time take the photo when you're sober!


--------------------------------------------------------------------------------

Method 2: fixed proproations height to width

This method fixes the ration of the height to the width of an image. It's useful if you want your image, for example, to end up being 4x6 [small photo size], or 8x10 [medium format photo size], or 14x10 [larger print size], etc.

Click on the Crop Tool
In the upper left corner, set the desired image dimensions, e.g., 4x6, 14x10, etc.
Repeat B1 …but this time you will notice that the selection lines for the crop will be in fixed proportions.




-----------------Lesson 4: Rotating the Image -- Correcting a Horizon Line [3 ways to do it]---------------------------------------------------------------

In both images, there is a horizon line problem.Cropping won't fix that problem, so it's best to first fix the horizon line and then crop the image to it's desired final frame.

For this lesson, work again with the 'captain cat' image. The horizon line is further off and easier to see and fix.

If you are interested, here is my 'captain cat' image with the horizon line fixed and cropped: "Ray's Captain Cat #2"

Guide Lines

It's sometimes useful at the start to have a horizontal and/or a vertical guide line on your image so that you can see whether a form is true horizontal or vertical.

To get a 'guide line' do the following:

VIEW MENU -> New Guide -> Horizontal
Click on the MOVE TOOL -> move cursor over the guide line, move the guide line to the horizon line on the image. This will give you a feel for how far off the horizon line is.
[note - the guide line will not become a part of your image ... when you're done with it do the following:
VIEW MENU -> Clear Guides
Method 1: Using the Rotate Command

This method is done by 'eye' ... you adjust the horizon line until it conforms to the horizontal guide line.

SELECT MENU -> All
EDIT MENU -> Transform -> Rotate
Now that you've rotated the image, you can crop it as in the previous lesson to achieve your final 'Captain Cat' image.




--------------------------------------------------------------------------------

Method 2: Using the Measure tool

Click on Eyedropper Tool -> Measure Tool
Click anyplace on the horizon [where the water meets the land] and drag along it and release it. You will be creating a line that is exactly parallel to the flawed horizon line in the image.
You need not drag along the entire length of the horizon. And, it sometimes helps to click on the 'zoom' tool to make the image larger so that you can more easily place the measure tool on the horizon line.
Note that you can adjust the ends of the measure tool line ... so you don't have to get it right when you drag it.
IMAGE MENU -> Rotate Canvas -> Arbitrary
Again, now that you've rotated the image, you can crop it as in the previous lesson to achieve your final 'Captain Cat' image.



--------------------------------------------------------------------------------

Method 3: Using the Crop Tool

Click on the Crop Tool
click on the upper left corner of the image and, holding the click, drag to the bottom right corner of the image. This will produce a selection line around the entire image with 8 small boxes at the corners and midpoints.
release the click and move your cursor around one of the corner boxes until you get a rotation arrow [see image at right].
then holding onto the click, rotate until horizon is correct

Lesson 5: Fixing Blemishes

For this lesson, use the 'sunset' image. It has several rather obvious blemishes.

To fix blemishes, the clone stamp tool is used. If you don't know where that is, click on the Tool Bar Image now.

The idea is to select an area that is similar to the blemished area, and to stamp that unblemished area onto the blemish to eliminate it.

Method:

click on the clone stamp tool
Select stamp brush type and size [top, left box]
Place your cursor near where you wish to correct a blemish. You are looking for colors and textures that will substitute for the flawed area. Often, this is an area right next to the flaw.
Hold down option key and click where you want to capture the pattern to be stamped onto the flaw
Release option key and stamp where the blemish is



Some things you need to know:

In the image above right, beside the word "Brush:" you see a solid black dot and the number "39" next to it.

The solid black dot is but one brush type.

My preference is to use a soft brush such as the one shown in this image.

When you first select the clone stamp tool and click on the image, if you are not holding down the 'option' key on the keyboard, you will get a message which tells you that you have to hold down the option key.

Having done so, you should click near the blemish and you will see a circle and an cross hair telling you that this is where you've decide to select part of the image to stamp over the flawed part.

Next you release the click, move the circle over the flaw and click. The flaw will disappear because you are stamping the non-flawed neighboring part of the image over the flawed part. Sometimes you may have to click several times or move the circle from left to right across the flaw.

At this point, you should practice correcting all of the flaws in the sunset image, then you should straighten the horizon line, then you should crop the image.

If you'd like to see my finished produce when I've done all of that, click on "Ray's Sunset Image". However, note that we have yet to correct the image for color ... it's too dark.




RECRUIT . BOY

cheers
