Image Quality and Re-rendering
The design doesn't have to change. The presentation might.
The standard has shifted
The rendering quality that was acceptable as a student two years ago is not the same as your current standard. Skills develop continuously, tools improve, and your eye for what constitutes a convincing, atmospheric, well-composed rendering becomes more refined with every project. The work in your portfolio should reflect where you are now — not where you were.
This doesn't mean redesigning every project you've done. In many cases, the design concept is strong and worth keeping. What needs to change is the graphic quality of the presentation. Re-rendering a project to your current standard is one of the most effective investments you can make in your portfolio.
A direct example
The two spreads below show the same project — the National Congressional Cemetery in Washington D.C. — at two different points in time. The design didn't change. The same concept, the same spatial organization, the same programmatic approach. What changed is everything about how it's presented: rendering quality, image selection, composition, use of space, and the overall professionalism of the graphic package.
Side-by-side comparison of the same portfolio project presented seven years apart. LEFT: 2002 original — early 3D rendering quality, busy layout, uneven image processing, heavy text, less confident use of space. RIGHT: 2009 re-rendered version — dramatically improved rendering quality with convincing lighting and material quality, cleaner image selection, more confident layout with intentional negative space. Both images already provided. Annotate the specific improvements: rendering quality jump, image cropping decisions, layout breathing room, caption typography.
Both spreads represent my student work at the standard of their time. The 2009 version represents where the work was capable of being with updated skills and tools applied to a strong existing concept. That is exactly the opportunity available to you right now with your own best work.
When to re-render
Re-render when your current rendering skills would produce a meaningfully better result than what you have — and when the design concept is strong enough to be worth the investment. If the project would look substantially more professional, convincing, or atmospheric with updated graphics, the time is almost always worth spending.
When to redesign instead
Redesign when better graphics wouldn't save the project — when the design problem itself was resolved weakly, when the concept didn't develop, or when the project represents thinking you've genuinely moved past. Better graphics applied to a weak design will still produce a weak portfolio spread. Also consider taking a project that feels light or incomplete and create new diagrams, sections, or perspectives for them to bring them up to your current standard. Be honest about which situation you're in.
Technical standards
For print output: render and export images at 150ppi at final print size minimum. For digital presentation: 150ppi is generally sufficient at screen resolution, but higher-resolution source files give you flexibility. Higher resolution doesn't automatically equal better, it usually means slower and more combersome files.
Name and organize your source files clearly. The ability to go back and update a rendering without rebuilding from scratch is worth establishing from the beginning.
