INF1090 Part Deux Photography- Photomanipulation
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.
First Steps We are going to look at some simple things we can do to edit our pictures Have fun!
Once you have selected the area, go to Image -> Crop to Selection
Voila Now all I have is the two people, and not the freaky thing in the pool.
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.
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.
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
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.
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?
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.
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.
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.
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.
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
Assignment 2- Using Layers, Effects and Rubber Stamp Get a picture of someone or yourself Add some new interesting features to yourself A 3 rd 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
Make a new Path Each time you make a new path, make the new path in your dialogue box
Repeat this Process Until you have everything traced that you need!!!!!!! Tip: for straight lines with this tool all you have to do is click where it starts and where it will end, you do not have to drag the mouse
Make a new Layer We will paint on this this layer
Adding Colour Go here to Stroke (paint) the path. Right-click on a path to choose this option.
There are lots of options Your colour The style
In my example here I traced the object in a variety of colours and sizes. I then added a Gradient background to my image.
Assignment 3 -Pathways Use different paths to trace around an image Use different colors to increase the detail Put a gradient background in your image.
