8 Paint.Net Color Window You can show more or less of the color window. You can set a primary and secondary color. You can work in RGB or HSV. You can set the transparency of a color selection. You will often set the color by using the eyedropper tool. There are also color palettes for low-depth images like.gif files or icons. Let s demo the color window.

9 Exploring the Menu Bar Much of the photo editing capability of Paint.net is in the menu bar. The Image menu provides cropping, resizing and rotation. The Adjustments provides brightness/contrast, hue / saturation, black / white, levels and other adjustments. The Effects menu provides a rich array of special effects, plus some common actions like red-eye removal. Let s explore some of the menu bar actions.

11 Paint.Net Layers An image is comprised of one or more layers, stacked vertically. The image you see is the composite of viewing through all the layers, top to bottom. The background layer is the base image. Each layer applies its modifications to the layers below it. You can reorder the layers to change how they affect the composite image. You can also turn layers on or off. Let s look at some simple layer actions.

12 Example Project (1) Outdoor Retouch Cropping the photo Use the rectangle select, then crop image to selection Eliminating undesired elements Use the paint brush, pencil and clone stamp to get rid of people, poles, power lines, etc. Adjusting brightness, contrast and light / dark levels Use Adjustments menu as needed Adjusting hue / saturation Use Adjustments menu as needed Fix red-eye, if needed. Resize the photo (as appropriate) Save the final result and print or publish.

13 Example Project (2) Portrait Retouch Take an existing portrait (head shot) and re-do the background color. Use the Magic Wand selection tool. Use the color window. Use the Paint Bucket tool. Then adjust the lightness of the background. Use the magic Wand again. The use the Adjustments menu. Also adjust the overall contrast of the image.

14 Example Project (3) Restore an Old Photo Take a scan of an old black and white photo and restore it. Crop as needed. Straighten as needed. Also adjust the overall contrast of the image. Try the Black & White adjustment. Try the Auto-level. Adjust contrast & brightness. Then repair blemishes (spots, cracks) Caution easy to overdo it. Use the Clone Stamp. Use the pencil & paintbrush.

You can choose the file name, folder and file type. Flattened types include:.bmp,.png,.gif,.jpg,.tif and.tga You can also save the file as a.pdn (Paint.net) project file, which retains all the separate layers. Use this if you are saving in the middle of working on a complex image project. When you have the Save settings defined, click the Save button.
