I have a project I'm creating in Adobe Illustrator where I've been bringing in raster images and doing a "High-Fidelity" image trace to make them scalable and easy to manipulate. I've had some photos I brought in to the illustration that would look better as-is, but they aren't 300dpi. Most are 72dpi. For those who have seen results in print production, is a 72dpi photo saved in a 300 dpi CMYK file going to look shoddy, or will the quality be manageable. The photos don't have to look entirely life-like, but close.
I'd include specific examples, but I'd prefer not to for my client's sake.
