I just did a quick-and-dirty experiment combining these two ideas:
Steps:
- remove as much shadow as I cleanly could, since it would be on a different plane from the lettering
- reverse perspective transform (‘corrective’ mode in gimp persp tool)
- plot some fading grid lines
Conclusions:
- Not in perspective is definitely easier to read.
- Lighter font is, too
- fading grid lines don’t work that well in this particular design.
I also made a few variants, mainly of the T, even more quick+dirty, using GMIC filters, might inspire some ideas:
