  1. INF1090 Part Deux Photography- Photomanipulation

  2. Open up GIMP 2! • We are going to explore how we can edit photos and make them better. And yes, it’s actually called GIMP. • This unit will show you a variety of editing techniques, from the very simple to more advanced offerings. • This slideshow is a guide on what you will do with your own photos. Feel free to follow along with the examples before you do your assignment.

  3. First Steps • We are going to look at some simple things we can do to edit our pictures • Have fun!

  4. GIMP Editing Area Tools

  5. Cropping a photo • Open an image in GIMP that you took • Find an image where there is too much of something that you want to get rid of. • Find the Rectangle Tool in the toolbar and click on it

  6. This one

  7. Once you have selected the area, go to Image -> Crop to Selection

  8. Voila • Now all I have is the two people, and not the freaky thing in the pool.

  9. Adding Filters • Filters can add an interesting flare to your photos • They can make your picture look more interesting or mysterious • Be careful! Filters can make things look tacky if overused. Find one that looks good! • You can increase the intensity or the amount of the filter that is used using a slidebar.

  10. Filters • Here is where they are

  11. I used the Cartoon filter

  12. Under the ‘Distorts’ option I chose ‘Emboss’

  13. We can also adjust how bright or dark our images are

  14. Brightness/Contrast • Brightness controls how dark or light the image is • Contrast adjusts the intensity between the dark and light colours, or black and white.

  15. Before After

  16. Adjusting Colour • The previous example was black and white. • Let’s see what we can do with a colour image.

  17. Go to Colours -> Colour Balance • You can manually adjust which colours appear in your image. Look at this drastic change in appearance.

  18. Go to Color- Hue/ Saturation • Here you can control: The colours used The brightness The intensity

  19. Adding Text • Now we will look at adding text to an image. Click on the big A button to get the text function.

  20. Text

  21. Some Text • I added this text to the top of my page • Notice that it also appears as its own Layer. Layers are like pages we can past different things on.

  22. Add more text • The text is hard to read as it is, so I want to put the same text behind it in another colour. I will duplicate the text layer. • Right-click on the layer that has the text and click Duplicate Layer

  23. Click on the old text layer • It is now underneath the new text layer • Change the colour of the text using the text tools on the left side of GIMP • My original text was red, so I changed this new colour to black, which will contrast with the red. This is a useful thing to do to make your text look more visible when put on another image.

  24. See what I did?

  25. Assignment 1 • Using one of your photos, crop it and add a filter to it • Change the brightness and contrast to a more suitable level • Change either the Colour Balance or the Hue/Saturation • Add text to the image, with a duplicate layer offset behind it to create clarity • Record what you did and why • Discuss your results. Do you like it?

  26. Fixing Mistakes • Photo editing software is a great way to fix things that have gone wrong. • The great thing about this software, is that we can work with things called Layers. • Layers are like separate transparent pages we can put things on. If we do something on one layer, it will not show up on another. • Layers are a great way to enhance things or make mistakes without worry of what you can do to your original image. • As a rule, NEVER EVER work on your background image. Always make a layer copy.

  27. The Layers- How to View Them

  28. Duplicating your original image • The new little box you see will show you all of your layers

  29. Uh Oh • As you can see, this man did a bad job making himself look good on eHarmony. Let’s help him out. Clearly he needs some better editing skills.

  30. Copy the image into a new layer

  31. We need to fix this area

  32. Find the Colour Picker Tool • This tool will sample the colour in a part of the picture that you click on • In this example, we want to Select the wall colour.

  33. I used the Paintbrush tool • After selecting the colour with the eyedropper, I painted over the area that looked wrong. This still doesn’t look good enough. There is something else we can do.

  34. Delete the previous layer • Make another background copy. • This time, we will use the clone stamp tool. • Hold down the CTRL key and select the area to Copy. The clone stamp tool will copy And replace a section of the image In this case, we want to copy the Background.

  35. Making Adjustments • You can adjust the size of the brush that you use • Changing the Opacity changes how see-through or solid what you are doing will be • It is a good idea to not make things Have a low transparency when first editing

  36. I got rid of his extra-wideness

  37. Making things Funny • With Dennis Rodman. Create a copy of your background layer.

  38. Add Transparency to the Layer • You need to do this so that you can erase parts of it later. Click on Alpha Channel to do this.

  39. Another Mouth to Feed • Using the Stamp tool, I put another mouth on his forehead on the new layer. Hold down CTRL!

  40. More • I want to get rid of the extra stuff around his new mouth. To do this, use an eraser and adjust its size and opacity.

  41. End Result

  42. Assignment 2- Using Layers, Effects and Rubber Stamp • Get a picture of someone or yourself • Add some new interesting features to yourself • A 3rd arm, another head? • We want to use the tools we have learned, like the rubber stamp and lasso, magic wand • We want it to look funny, but realistic and blended together • Adjust the layers with contrast to match things better

  43. The Pen (Paths) Tool

  44. A powerful tool to trace over images

  45. How to Use Click on this tool here

  46. How to Use • We need to see the different Paths we will use, like how we can see and select different layers, so go and enable this feature to appear in your tools:

  47. My Object • I am going to trace the car • The first thing I will do is zoom in using the + key

  48. The first thing I will trace is the wheel well • I click and drag with the mouse, making a straight line • I will then click HERE to make the line curve

  49. We get this: By holding down the CTRL key you can move the curve around so that it matches the shape you want it to.
