ARRI vs. RED vs. Sony: What the Spec Sheets Don't Tell You
A practical comparison of the ARRI ALEXA 35, RED V-RAPTOR 8K VV, and Sony VENICE 2 that goes beyond resolution and dynamic range to cover color science, codec pipeline compatibility, rental economics, and real post-production cost implications in 2026.
What Circle of Confusion Should You Use for Your Camera?
A practical guide to choosing the right circle of confusion value for full frame, Super 35, APS-C, and Micro Four Thirds sensors. Match your CoC to your delivery standard, not your camera marketing.
ARRI vs. RED vs. Sony: What the Spec Sheets Don't Tell You
A practical comparison of the ARRI ALEXA 35, RED V-RAPTOR XL, and Sony VENICE 2 that goes beyond resolution and dynamic range to cover color science, codec pipeline compatibility, rental economics, and real post-production cost implications in 2026.
Aspect Ratios in Film: A Practical Guide from 1.33 to 2.76
A practical guide to aspect ratios in film covering their origins, the technical implications of each choice, DCI container specifications per SMPTE ST 428-1, and the production decisions a DP and director must make before day one.
How to Read a Dynamic Range Spec Sheet (And Why Camera Marketing Lies to You)
Manufacturers measure dynamic range differently, and the numbers rarely match real-world latitude. This post explains how to read the actual usable range using data from 8 popular cameras.
Sensor Crop and Focal Length: The Complete Reference Table for Every Major Camera
A definitive reference table of sensor sizes, crop factors, and focal length equivalents for every major cinema and hybrid camera in use in 2026, with practical guidance on how crop factor changes your lens choices and field of view across platforms.
What Circle of Confusion Value Should You Actually Use? A Sensor-by-Sensor Guide
Most DoF calculators pick a default circle of confusion value and never show it to you. Some default to 0.029mm for every camera regardless of sensor size. Others use 0.025mm for 'cinema' modes that span three different sensor formats. Here is how to find out what your app is actually using and whether it is correct.
What Happens If You Run Out of Cards on Set?
A practical recovery protocol for when your media fills up mid-shoot - covering in-camera offload options, emergency purchasing, and how to restructure the shooting day without losing footage or shutting down production.
Field of View Calculator: How to Pre-Visualize Any Lens Before Renting It
Renting a lens without calculating its field of view on your specific sensor is the most expensive guessing game in cinematography. Two minutes with a field of view calculator tells you exactly what a 35mm looks like on your body versus a reference film, which lens matches the director's visual reference, and whether the rental is worth the cost.
How to Calculate How Many Cards You Need for a Shoot Day
The answer is not just codec bitrate divided by card size. It depends on whether you can offload and reuse cards, how many cameras are running, and what happens if offload takes longer than expected. Here is the calculation that covers all three scenarios.
What Circle of Confusion Should You Use for Your Camera?
The circle of confusion value in your DoF calculator is sensor-format specific. Using the wrong CoC produces inaccurate depth of field predictions on set. Here is exactly which value to enter for every common cinema and mirrorless camera.
