Editing photos? Remember to keep your originals! Even if you're not a professional photographer, you probably have some photos that are important to you: weddings, graduations, family vacations, old friends, etc. Hopefully, you're already backing up your important digital photos along with your other files, either with an external hard drive or a cloud backup service. But even if you're keeping your photos safe, there is still a risk of  damaging them when you edit them . For example, let's say you decide to convert a photo to black and white to give it an artistic touch. If you change your mind later on, you won't be able to convert it back to color because the color has already been removed from the image. There are many other kinds of edits that are irreversible once you've saved the image because they remove information from the image that is  difficult or impossible to get back . These include cropping, resizing, and many types of filters. Other adj...

What is 3D printing? 3D printing is a process in which a digital model is turned into a tangible, solid, three-dimensional object, usually by laying down many successive, thin layers of a material. 3D printing has become popular so quickly because it makes manufacturing accessible to more people than ever before. This is partly due to the price (the starting price for a basic 3D printer is about $300), but also the small size of the printers compared to traditional manufacturing. How does it work? First, a virtual design of the object is made. This design will work like a blueprint for the 3D printer to read. The virtual design is made using computer-aided design (CAD) software, a type of software that can create precise drawings and technical illustrations. A virtual design can also be made using a 3D scanner, which creates a copy of an existing object by basically taking pictures of it from different angles. Once the virtual model is made, it must be prepared for printing...

Introduction There's almost no limit to what you can do in Photoshop, but first you'll need to learn the fundamentals. We're going to talk about some of the most  basic image adjustments  you can make in Photoshop, including: Cropping : If you want to remove parts of an image, you can  crop  it. You can think of cropping like using a pair of scissors to  cut out  the parts you no longer want. Resizing : If you want to make an image smaller or larger, you can  resize it. However, keep in mind that making an image larger than its original size generally does not look good. Rotating : If you want to change the  orientation  of an image, you can  rotate  it to the left or right. Cropping There are two main ways to crop an image in Photoshop. You can either use the  Crop  tool or make a selection with the  Rectangular Marquee  tool. These methods work a bit differently, and you may find that you prefer us...

Introduction In Photoshop, saving works a bit differently from most other applications. Instead of working with one main file type—such as .docx in Microsoft Word—Photoshop offers a variety of ways to save your images. In this lesson, we'll talk about the  different saving options  in Photoshop, along with some common reasons to save files in different formats. Saving options When you save a file in Photoshop, you'll have many different saving options and file formats to choose from: PSD : This is the   default file type  for Photoshop documents, although you won't necessarily use it for every image. It will save your   layers   and all of the other information in your image so you can easily re-edit it later. PSD files are designed to be opened in Photoshop, so if you want to share the image with others you'll also need to save a copy of the image in a common file format, such as JPEG. Common file formats : You can save images in a variety of c...

Introduction Images that come straight from a digital camera aren't always perfect. As you start to gain more experience with image editing, you may notice some  recurring problems  with images that you'll want to fix. For example, some images may be too bright, while others may be too dark or too blurry. There are many different  corrections  that can make your images look dramatically better. Some of the corrections we'll cover in this lesson include: Brightness   and   contrast : If an image is  too bright  or  too dark , you can adjust the  brightness  and  contrast . Color : If the colors in an image are  muted  or  dull , you can use a variety of color-correction tools, such as  saturation . Sharpness : If an image is  less clear than you'd like it to be, you can  sharpen  it. Want to see the difference that corrections can make? Take a look at the example below. It only took ...
