Professional Image Editing Made Easy with Affinity Photo

By: Jeremy Hazel

Overview of this book

In this book, you’ll explore the Affinity Photo program through practice-based learning as you make popular photo edits, learning the tools and techniques in conjunction with the workflow concept. Instead of comprehensive description of the tools, you’ll learn through practical application and understand why they work, not just how they work. This is neither a technical manual nor a workbook but a project-based hybrid approach that provides a deeper understanding of how to use each tool to achieve your goal. Starting with the fundamentals of navigating the interface, understanding layers, and making your first edit, this Affinity Photo book gradually increases the complexity of projects. You’ll go from single-layer edits, composites, and RAW development to putting together a complex composition using the tools that you've learned along the way. Additionally, you’ll learn the best practices used by expert photo editors for a flawless finish. By the end of this book, you’ll have a good body of work, be able to evaluate the edits you want to make, and achieve desired results with Affinity Photo.

Understanding DPI and why it matters

As previously mentioned, pixels form the images, and how many there are in an area creates the detail or the resolution. So, the typical way this is communicated in both the print and electronic art world is in dots per inch (DPI). This represents how many pixels are present in an area of one square inch, and quite simply, the more dots per inch, the higher the amount of detail.

Typically, if you are making a piece of art for a digital screen, the general DPI is 72, as most monitors cannot go past that. However, if you are doing print work, the minimum DPI is 300, as anything less will show fewer and fewer details.

Setting the DPI affects the file size because, obviously, the more information (in this case, DPI), the larger the file is going to be. In the following figure, simply changing the DPI of the file from 72 to 300 increased the size of the file substantially:
