A while ago I saw Freddie Williams' perspective grid path (you can find it here
) which is a great idea and saves a lot of time when drawing perspective.
However, a lot of the lines in his grid are cut off before the vanishing point to avoid that ugly clutter it makes.
If you need the grid for one point perspective where the vanishing point is in the picture that's fine, but otherwise I just found the many cut off lines confusing, so I made my own grid.
This is a .psd file with the grid. There's a guide to what to do with the path in the file if you're not familiar with using paths in Photoshop.
Feel free to use this as you please
