I have tried a variety of different manipulations to achieve a old-style architectural render. Here is what I've tried, perhaps the workflow and quality can be improved.
- Desaturated image
- Adjusted levels and contrast for clear designation of lines
- Filtered using artistic pencil sketch
- Added sepia tone
my result was less than stellar.
Here is a photo that I would like to change into an old-style rendering.
here is the result that I'm looking for.
