Photoshop, InDesign and Illustrator: The Ultimate Guide on How to Become a Designer

Vector graphics are the most commonly used illustrational elements in all types of design. Their main advantage is that they are resolution-independent, which means they can be scaled and printed out in any sizes without losing their quality.
InDesign is a hub where your edited images from Photoshop and your artwork from Illustrator ends up most of the time. This is where you can combine all your work and prepare it for output to print or web. InDesign offers a lot of creative ways to work with images and has a huge variety of typographic features and it can handle hundreds of pages of layout full of images, illustration and text without any issues. It is a very powerful application and crucial for every designer in the industry.
Every digital photo is made up of pixels, which are like tiny building blocks of the image. You can see them if you zoom close enough to your photo. The amount of pixels in the photo will give you the image size or dimensions but not the resolution. That is something you can set if you intend to print out your photo or use it in a print design project. The higher the resolution the more pixels of the image will be used on an inch distance of your final print. The industry press quality standard is 300 ppi, which means 300 pixels of your image will be printed onto an inch distance of your print. That means the larger your image pixel size is the bigger format you can print it out while maintaining good image quality on the print.
Managing your files is very important. As a designer you will work with thousands of images and you have to be able to decide what file types to choose for specific elements of your designs and how to organize them on your computer so that you can find them quickly and easily.
