This is a guest post by Cinematographer Ryan E. Walters.

Welcome to Part 02 of Some Like It RAW, where I am comparing the Arri AlexaBlackmagic Cinema Camera, and the RED EPIC. My goal for these tests is to explore how each of these cameras handles real world shooting environments. Part 01 explored how these cameras handle IR pollution. In Part 02, I test the limits of low light levels, or underexposure. Continue on to watch the 11 minute video, read my summary, and get the downloadable RAW frames from each camera. More »

It’s something many of us have come up against during one production or another: noise. We’re mostly talking about digital choma (color) noise, and not the much more pleasant grain texture of actual film (subjective, I know), or the less-obnoxious texture of digital luma (brightness) noise. Chroma noise is what rears its ugly head when we’re pushing cameras to the extreme, and for many of us, that means Canon DSLRs. In the tutorial below, Lucas Pfaff takes us through some of the camera settings and programs he uses to get the cleanest looking footage possible. More »

Now, as part of the Technicolor CineStyle picture setting release, the user manual mentions that one should shoot at “multiples of 160.” I assume Technicolor knows what they’re talking about, but the question remains.

When Red Giant Software released their latest Magic Bullet product, Denoiser, I wondered how it would compare to my plugin of choice for noise reduction, Neat Video. Now, thanks to Andrew Reid at EOSHD, I don’t have to do this comparison myself, as he’s just compared the two: More »

My three year-old MacBook Pro recently started emitting a constant racket from its left fan (which sounds something like this). Most people will tell you you need a new fan for $50, but I decided to try to fix it instead, and so far (it’s been two weeks nine months), the repair has worked great. As any google or youtube search for “noisy macbook pro fan” produces thousands of results, I hope this saves someone fifty of their hard-earned bucks. More »
