I have to design artwork to go on a sheet 3050mm wide by 2600mm high and placed on a building to be viewed at about 15-20 meters.
The scene will be a living room with pictures of various furnitures cropped and placed in the scene.
I don't really know how to set up my document to make it easier to edit as my PC is finding it difficult to handle such a large file.
I have it currently set at 150dpi. I'm thinking about reducing the scene in half so 1500 x 1300 and setting dpi at 300, so when I double the size it will half the dpi. Not sure if this is how it works or the final result will be the same. Any guidance would be great.
