Editing 101

Vocab: filter, grayscale, monochrome, sepia, tools

Learners can:

  • Outline the steps for enhancing or retouching an image using color tones
  • Edit a photograph using color tones and filters
  • Identify the purpose of using different color modes and filters

Editing can help a most ordinary picture look extraordinary. Proper editing can level up the quality of any photograph and make it even more memorable. You can use photo editing to improve a photograph in any of the following ways:

  • Removing unwanted objects, people, and details from the photograph
  • Altering the appearance of your subjects by adding makeup, fixing their hair, and so on
  • Enhancing or changing a photograph's colors
  • Cropping the image to exactly what you want to appear
  • Adjusting the brightness and contrast of the image
  • Sharpening the photograph
Many tools and computer programs are designed to help users with specific tasks that you can use to edit photos. You can go online to find free tools and applications, such as Pixlr and GIMP, or you can purchase tools like Adobe Photoshop and Lightroom, which provide subscription services.


Click HERE to find Adobe Tutorials for Students! Each tool has benefits and drawbacks, so you must investigate which best suits your needs. First, think about what you would like to be able to do when you edit your photographs. Then, research to discover the right tool for you. Remember that some tools are simple and easy to use, while others are complex and may take a long time to learn. Whatever tool you choose, remember that the rewards of learning how to edit your work are worth the effort. You will be able to enhance your photos and make them unique! For this lesson, you can use GIMP or any other editing application. If GIMP is not already installed on your computer, refer to this unit's Prep for Success lesson and download it. When you have GIMP open, continue to the next page to follow instructions and learn about color tone.


One of the most effective photo editing techniques is to change a photograph's overall color, replacing the original set of colors with shades of one color or another. Recall the way the window photograph you saw earlier was transformed into shades of black and white, sepia, or blue. By changing a photograph's overall color, you can dramatically alter its look and feel. You are about to learn how to use photo editing software to alter a photograph's color palette, just like what was done with the photograph of the window. You will use the software to convert a color photograph into black and white or sepia tone. You may use any color photograph you already have taken, or you may download and use the photograph provided in Edio.

Changing Color Tone

To change the color of a photograph using the GIMP photo editing tool, follow the steps below. If you use a different tool or editor, the steps will differ; however, they are likely to be similar. First, open the image in the tool you will be using.Go to the File menu, and press Open. You will then have an opportunity to select the image you want to edit.

The Open Image window opens. Navigate to the location in which you have stored the image you selected. Select the image, and press Open. The photograph will now open in the editor, ready for your edits.Now that you have opened the image, you will experiment with simple ways to change its colors. Keep going to know the significance of using black and white tones in photographs.

Black and white photography can create irresistible images using different shades of gray, ranging from white to dark. As you know, black and white photographs were among some of the first created. The first color photographs were taken almost 35 years later. When you convert a color photograph into black and white, you touch a bit of history.Any photograph with a single color tone across the image is monochrome, so black-and-white photographs are monochromatic. When it comes to image editing, remember that not every composition works well in monochrome, including black and white.

πŸ”₯ Converting to Black and White

Before you eliminate color from your photograph, consider whether the change will enhance it in some way. Converting a color photograph to black and white can make the photo look timeless. It can also help remove the distraction of color, creating a focus on the subject, the textures, the shapes and patterns, and the composition of the image itself. However, converting a photograph to black and white can also remove detailed information you might want to preserve. After all, the photograph will no longer represent the colorful world in which you live. You need to know why you are converting a picture to black and white before you make the change. If you cannot pinpoint a good reason or set of reasons, your photograph may not be meant to be monochromatic.

Monochrome Photograph

πŸ”₯ Convert a Color Image to Black and White

Step 1

Desaturate:Desaturate all of the colors to turn your picture to black and white (BW), also known as grayscale. Steps to follow: On the Colors menu, press Desaturate, and then select Desaturate.

Step 2

Use Black and White Filter:The Desaturate window opens. You can choose a filter option from the Mode drop-down menu.

Step 3

Save the Image:Press OK when you have decided on the option you want to use.


Once you have changed the color tone of your photograph, you will want to save the new file in a standard format. A standard format makes it possible to use the image in a variety of ways, from posting it to social media to including it in a report or presentation.Both GIMP files and files created with other photo editors need to be exported as .jpeg files before they can be opened for use in a wide variety of common computer tools. These include popular word-processing programs, publication tools, and presentation applications. View the information below to learn how to save a GIMP file as a .jpeg. Remember that the process you use with your own photo editor may differ from the process described below. However, it is likely to be similar.

πŸ”₯ Converting to Sepia Tone

Have you ever seen an old photograph that seems to have faded over time?Recall that before digital photography, photographers used film and chemical processes to capture and then print images. The use of such chemicals gave the processed black-and-white film and photographic paper a warmer tone. πŸ”₯ They had a reddish-brown tint to them, known as sepia.

Today, using some simple filters, you can alter any image to make it look old and sepia toned. The sepia filter adds a brown tone to digital photographs, enhancing them with a warm look that is very calming to the eye. Because a sepia tone makes an image look old, it is especially useful for photographs of older subjects and objects that are still around today. The sepia tone filter is available in most image editing applications and software tools. You will now learn how to use the GIMP tool to convert a color photograph into one that is sepia toned. For this portion of the lesson, you may use the same photograph you used earlier or you may select a new one. If you want to, you may use the photograph you downloaded earlier in the lesson.

πŸ”₯ Converting to Sepia Tone

Convert a Color Image to Sepia Tone

Step 1

Choose the Tone: Open the image in the GIMP tool. Go to the Color option, press Desaturate, and then select Sepia.

Step 2

Select the Effect Strength:The Sepia dialog box opens. You can adjust the effect to your desired tone by using the Effect strength bar.

3. Sepia

2. Black and white

πŸ”₯ Match each of the following tones with the correct image.

1. Color

πŸ”₯ Filter Options

πŸ”₯ Most photo editing tools provide a variety of additional filters, preset ways to alter images to give them a certain look, from adding blur to making tones colder (bluer) or warmer (browner). Filters can even add rounded corners to photographs or make them translucent so that text or images can be made visible below them.Every editor has its own set of filters, so be sure to investigate all of the filters available to you. One example, the Old Photo filter option in the GIMP tool, is described below.

πŸ”₯ Filter Options

Step 1

Choose the Filter: Go to the Filters option, press Decor, and then select Old Photo.

Step 2

Save the Photo: A dialog box opens. Change the settings as desired, and press OK to save your photo.

Follow the steps below to submit both the original and the edited photographs: Use the presentation template attached on Edio. Add the two photographs to a presentation side by side, with the original image next to the edited version. Save the presentation as FirstNameLastNameEditing101Upload your file.Answer the question: Which filter did you apply to your photograph? Explain briefly the purpose of using the filter. What differences can you point out between the original photo and the edited photo?

Choose your own image, or use the image provided in this lesson. Open the image in GIMP or a photo editor available to you. Then, use any editing technique you learned in the lesson, such as manipulating color or using filter options, and save the edited photograph in a .jpg format.
