Take Over Tuesday: Featuring Jim Doolittle
About this episode
It’s Take Over Tuesday where you the listener run the podcast.
And this week’s episode is featuring Jim!
From CRT to HDR: 25 Years of Image Accuracy with DJ’s “Projector Guy”
Today DJ finally brings on his "projector guy,” Jim Doolittle—an ISF-trained calibrator and longtime friend he's referenced on the show for years. They trace Jim’s path from audio pro to video calibration pioneer, his rare one-on-one training alongside Joe Kane and Joel Silver, and how that shaped his approach to accurate images. They dig into why internet advice can mislead without full system context, and why every home theater is a series of compromises—placement, optics, room, gear, and budget. Jim explains stacking DLP projectors for HDR brightness, what makes DLP feel sharper than LCD, and why proper placement beats keystone every time. The guys get deep on fundamentals: contrast as the top driver of perceived quality, grayscale as the foundation for color, the genius of chroma subsampling (4:2:2 vs 4:4:4 vs RGB), and how our eyes’ rods and cones inform video engineering. They also cover rear projection trade-offs, lens focus uniformity, why calibration still matters today, and how modern home setups can surpass the moviegoing images many of us grew up with. If you’ve ever wondered whether your setup is “right,” this episode’s for you.
Highlights include: the perils of partial information online; the evolution from CRT to fixed-pixel displays; practical projector placement tips; why keystone halves effective resolution; black-and-white’s surprising “3D” depth; when and why to use external video processing (like Lumagen); and what “artist intent” really means in the age of Atmos vs 5.1. It’s two hours of hard-won wisdom from the calibrator who’s kept DJ honest for 25 years.
