Renderings from Autodesk Revit Architecture are quite photorealistic, but also stiff and artificial. I like the effect of "hand drawn" lines because it blurs details, retouches imperfections, and gives a feeling of warmth to the image. During the examination session at the university I finished a few projects, all renderings of architecture, urban planning and landscape. I want to soften them by using AKVIS programs.
This is my school project - City by Water.
Look at the original image and the result after using AKVIS's programs.
Press the button and save the result.
The painting is done!
