Photo Editing

What is digital photo editing?

Digital photo editing is defined as the enhancement and manipulation of a photograph using photo editing software. When you think of software,
what do you think of? That’s right, digital photo editing is done using a computer. This can be either a small computer, such as the ones that are
on-board many digital cameras, or a bigger laptop or desktop computer separate from the camera. Through the use of software, photos can be
manipulated in order to fix problems, make colours stand out, isolate sections of the photo and more.Photo editing software is full of powerful tools
that we can use to make good photos even better and turn regular photos into works of art!

This may surprise you, but many professional photographers don’t get the perfect shot every time they press the shutter button.Thankfully for them,
there are amazing digital photo editing software programs out there. Thankfully for us, we can use them too! With digital technology,almost anyone can
be photographer, and with the amazing tools we have we can enhance our photos to make them look much more professional. When you start learning
all the tools, you will really be amazed at what you can do.

Why edit photos?

There are a lot of reasons to edit your photos. For most people, the biggest reason is to fix a mistake. Let’s say you took a greatphoto but there was some
dirt on your lens. Now you have a dark spot on your photo.With your editing software, you can go back and use what’s called a “clone” tool to cover up that
dark spot.Also, your photo may seem kind of dark. You can easily lighten a photo by changing the “brightness” level. Now your photo is flawless! Another
reason you might edit your photo is to produce artistic effects. For example, maybe your image seems a little “busy”. This might mean using what’s called
a “blur” effect to create a point of focus that draws the eye in. For instance, if you have a photo of a bunch of fall leaves on the grass, but they’re all in focus
and it seems distracting, you can use the blur feature to blur out some of the leaves, which is essentially changing the “depth-of-field” of your photo. You are
creating a shorter depth-of-field and focusing on just one area of the image, which creates something with an entirely different feel. With your photo editing
software, you can reveal the true potential of your photos. Using the skills you’ll learn in this project, you’ll be able to manipulate your pictures any way you
like, bringing colours to life, making focus that much sharper, and even bringing photos back from the brink of the trash folder. All you need is a digital camera,
a computer and some photo editing software. Let’s get started!

What can we do?

The Tools and Techniques of Digital Photo Editing There are many problems that can be fixed or elements that can be enhanced
with photo editing software. Most editing programs employ the features and tools that we’ll encounter in this project listed below.
Some examples of photo editing programs are Adobe Photoshop, iPhoto, Corel Paintshop, Photoscape, Google Picasa and GIMP,
to name a few.

Rotate: When you take a vertical photo, sometimes your computer mistakes it for a horizontal photo
when you load it into your editing program. For example, you may have taken a photo of the CN Tower,
but when you view it on your computer, it looks like it fell over. No problem! With the handy “rotate” tool,
which often looks like a rounded arrow, you can turn the photo at 90-degree increments until you get it perfect.

Cropping: Cropping allows you to create a new image by isolating a portion of your existing photo
and cutting out unwanted areas. The cropping tool usually looks like a box formed by a dotted line.
Click this tool and drag your mouse across the photo creating a dotted line box around the area you’d
like to keep and then clicking “apply” or “crop”.

Selection Tools: These tools are used to do just what you’d think: select parts of the photo.
Using selection tools, you can apply changes of colour, focus and exposure to only the area of
the photo that you choose. These tools can be the “marquee”, which is used to select rectangular or
other shapes with straight lines, the “lasso” tool, which allows you to select your area by freehand,
and the “magic wand” tool, which selects only a certain colour in your photo
(like a uniformly blue sky or the brown colour of someone’s hair).

Contrast/Brightening: Contrast and brightening tools work hand in hand with the tools listed above to help you repair your exposure. You can use the brightness tool to brighten or darken your overall photo. The contrast tool’s addition of colour depth can help define the tones in your photo, making it appear more evenly exposed. In addition, if your photo has very little colour depth (and this is especially noticeable if you decide to make your photo black and white), the contrast tool will also provide more definition and interest. Contrast tools can also be used to soften colour depth, which you might want to use if you’ve taken a portrait that makes your subject look a little rough around the edges. These tools look like slider bars along a line that can be moved left to right to adjust the overall contrast and brightness of your photo.

Red-Eye: The dreaded red-eye occurs when your camera’s flash reflects off the back of your subject’s eye. You’ve seen it. We all have. It’s that otherwise perfect photo of your grinning family around the kitchen table with glowing red devil eyes. It’s enough to give you nightmares! Thankfully, your editing software is especially well tuned to tackle those scary red-eyed demons and return them to your happy, To use it, click on the tool, adjust for size, and click on the shiny red circle in the middle of your Uncle Steve’s eyeball.

Special Effects: The sky really is the limit for what you can do to your photographs using your computer. You can cut out elements, paste in elements from other photos, make someone stand on their head, or even make pigs fly!

Framing: A really cool frame might be just what your photo needs. We all know framing can be done after the photo is printed, but did you know you can frame your photo digitally using your editing software? A lot of photo editing software programs have a wide variety of frames to choose from. Some are coloured, some are distressed (they look old or antique) and some are even crazy shapes. You can usually find them in your “adjustments” menu.

2. When you first open Picasa, you can choose to scan your entire hard drive, or just My Pictures, My Documents, and Desktop. It will then display your pictures it its Library view. You will find pictures you forgot you had because Picasa makes it so easy to view them. If you have pictures in folders other than My Pictures, My Documents, and Desktop you can add new folders manually by clicking on Tools / Folder Manager. The program will show photos in their respective folders.

4. Learn what each button in the "Basic" editing box does. Here is a brief rundown to help you get started:

  • The first button, "Crop", is pretty obvious. By clicking on it, you can cut out a part of your image. You can choose a manual size, or choose one of the preset ratios. Click "Apply" when you are finished cropping.
  • The second button, "Straighten", can fix a slanting horizon. Click on it, and use the grid and slider to rotate the photo until straight. Click "Apply" to save your changes.
  • The third button, "Redeye", is also pretty self-explanatory. If you click it, Picasa will automatically fix any red eyes on a photo and indicate them with a green square. If the program has missed any eyes, you can drag a box around them with your mouse and the program will fix them. If Picasa boxed anything that is not a red eye, you can click on the box for the program to ignore it. Click "Apply" when you are done!
  • The fourth button, "I'm Feeling Lucky" adjusts the lighting and colour of your photo, to what the program thinks is a better shade. This button is handy for fixing hazy and dull photos.
  • The fifth button, "Auto Contrast" heightens the contrast of your photo to a better level.
  • The sixth button, "Auto Colour" improves the colour of your photo and works well on dull photos.
  • The seventh button, "Retouch" can remove dust spots on your photo, which helps a lot if you had dust on your camera lens. Click the "Retouch" button and then click on a blemish on the photo, then move the mouse around the spot until it is removed. Click "Apply" to save your changes.
  • The eighth button, "Text" can add text onto your photograph. Click the button and then click anywhere on the photo to start typing. Use the appearing text box on the left to alter the font, size, colour and transparency of the text. Click "Apply" to save your changes.* The ninth and last button, "Fill Light", can lighten your photo if it is too dark. Move the slider up and down until your photo is perfectly lighted.

5. Learn what each button in the "Tuning" tab does. The following explanations clarify the use of the tuning tool:

  • The "Fill Light" slider has the same purpose as the last button on the "Basic" editing box. Slide it up and down to lighten your photo. Useful for when you forget to switch on your flash.
  • The "Highlights" slider makes the light colours on your photograph lighter and more obvious. Use it when you want the light parts in your photo to stand out.
  • The "Shadows" slider serves the opposite purpose the "Highlights" one. Use it when you want to make the dark parts of your photo darker.
  • The "Colour Temperature" slider changes the "warmth" of your photo. Blue is cold and red is warm. Move the slider to the left if you want to turn your photo bluer and move it right if you want to turn your photo redder.
  • The "Neutral Colour Picker" removes colour cast from photos. Click on the eye-dropper icon and then on a neutral black, grey or white area of the photo to adjust the colour.
