JPEG vs Raw file

Understanding the basics of photography and how digital images are stored is important if you want to be able to produce great images. Using tools such as Photoshop for editing can greatly enhance an image, but how it’s stored on your camera in the first place can make a big difference to what you can do to it later on.

Our Photoshop course not only tells you how to edit images, but gives you the technical understanding behind different types of image files, how colours are made up and how to understand image size and resolution. We also offer Advanced Photoshop training for those who want to take their technical knowledge further.
