There are a few things you need to know before starting to create logos in Photoshop. First, you will need to create a basic logo. This can be anything from a simple rectangle to a more complex design. Next, you will need to decide on the type of logo you want to create. There are many different types of logos available, so it is important that you choose one that is both unique and easy to use. Finally, you will need to decide on the size of your logo. This can be anything from small enough for use on a computer screen or small enough for printing onto paper. Once you have created your basic logo and chosen the type of logo, it is time to start creating the details!
