Determining DPI
DPI is determined based on two factors:
- The size of the final render
- The draft-to-final iterative process
The final render size is subjective and depends on what you need to convey in the image.
As outlined in Chapter 20, resolution affects render times: higher resolutions equal longer times. Start with low resolutions, using IRP presets or setting custom small sizes. Here are some useful initial resolutions for first and second drafts:
- 640 (width) × 480 (height)
- 800 (width) × 600 (height)
Useful resolutions for third and fourth drafts can range from these initial values to 1280 (width) × 720 (height). Final typical resolutions can be set between 1280 × 720 and 1920 × 1080.
