I’ve found a great tool to create collages in Photoshop. This is an extension that can be easily installed. I was looking for some tool like this for a while. This is very simple in use but requires some imagination. You may create rows and columns, set the spacing values and roundness of the corners.
Here is some example of the collages I’ve made using the images from our trip to Santorini.
Here is the link to download the tool. It is free!
