Using PaintShop Pro, you can create environments that are not real, but can still be realistic. Some templates can be found, online, where you would just have to add your own photos or designs to create a 3D room or element. The trick is to use the Pick tool correctly.

The Perspective Correction Tool
When you take pictures of objects, buildings or surroundings, you might not always be able to place yourself perfectly straight in front of it to take a centered and proportional photo. You might be at a slight angle because of the physical environment. Maybe you were just too much and in a hurry to move somewhere else. Either way, there is a tool in Paintshop Pro that will allow you to fix this issue.
