    Spike Lee's "Da 5 Bloods" shot Viet Nam flashbacks on vintage 70's 16mm fim stock

    I still have a can or two of 5247 in a freezer somewhere, maybe I should see if there's a market for it... speaking of that, I've got an undeveloped roll of 16mm from Director Mark Webb (500 Days of Summer, Spider Man, etc.) in the back of my fridge... I think his film professor at Colorado...

    CPU change result in software licenses breaking?

    In that case, definitely NO on the process! My swap out was changing an 8 core to a 16 core, with other improvements in the new chip design that resulted in a whopping render speed increase worth every penny of cost and the (nil) effort of doing it. If your changes don't result in at least a...

    Creating a community for DIY LED lighting stuff (DIY Quasars inside)

    The length is a factor (wire resistance) but also the number of LEDs/meter/yard is important.. the more LEDs, the more power needs to be distributed. I would suggest you run wires up along the strip and add power and ground to the other end. Perhaps a very crappy drawing will help...

    NAB 2019 rumors (and releases)

    My first NAB was 30 years ago, 1989. Here is a scan of the daily newspaper I kept, and a random ad from it... Back then, everyone wore suits or at least a tie. You couldn't take pictures in the hall. HD was big CRT screens and tube camera prototypes without a final standard...

    Shooting Stock Footage

    So 21 years ago I saw the need for sky time-lapse for my own projects and spent a summer & fall shooting 35mm with my old Wall camera... I shot every sunrise, thunder storm and sunset I could manage. I soon realized it was fairly unique and perhaps useful to others, so I burned .jpg sequences...

    GH5 Panasonic xlr adapter- anyone using it?

    The XLR adapter is overpriced, but it's worth it. Sound quality is on par with the BEST camcorders I've ever used (camera guy perspective, not a formal sound guy) and really is valuable for ease of operation. It uses more battery power (at least when Phantom Power is used), but I typically...

    Creating a community for DIY LED lighting stuff (DIY Quasars inside)

    This is a fun concept that I have a soft spot for and as hobby fun. I have a box of heat sinks and electronic bits from ebay with the goal of doing something DIY with the 100watt Yuji's myself. One question, has anyone mounted and used the super small diameter Yuji's...

    GH5 GH5s dynamic range tests

    So I did some tests for my own use, then thought I'd share... Your mileage may vary, etc. I'm prepping for some green screen work with the GH5s and have had great luck with the Natural picture profile in the past, so I wanted to compare it with VLOG-L at the low base ISO at two different ISO...

    FS700 Slog2 PP Reds look Orange

    I don't see them as any sort of universal replacement... Here's what I'm talking about... using the 2 stop LUT's on the same clip... no other adjustments other than flopping out the LUTs... (larger image so you can read the scopes)...

    FS700 Slog2 PP Reds look Orange

    I've not found that to be the case... I shot this 1 stop over-exposed, recorded to UHD ProRes... and no color adjustments beyond lift/gamma/gain using the appropriate Convergent/Nick Shaw LUT in Resolve... Regards,

    Just got a new camera - Sony F35

    What Mitch said. ANY digital camera today has the life span of a fruit fly compared to products from the film era. The death of new stock will end that of course, someday, maybe pretty soon. While in college, I purchased "new to me" a 35mm B&H 2709.... Worked as an animation camera/down...

    Home Built Motion Control Systems.

    Yes, when I have time... in fact, you will enjoy (and recognize) the selection of steppers I've got just waiting for me to get moving again... I'm going to crib your design as much as possible, certainly in the pan/tilt/roll aspects... I'm only really needing stop action motion control, as I've...

    C500: C500 & Odyssey7Q for WY-DOT Drunk Driving PSA

    Hi all... did a fun summer project for the Wyoming Governor's Counsel on Impaired Driving using the C500 and the Odyssey7Q recording Canon 4K raw. http://youtu.be/Dju6NFrbzT0 While I love the FS-700 Odyssey combo, sometimes I think the C500/Odyssey match-up doesn't get enough attention in...

    Best Material for Greenscreen?

    In the case of CC's paint, yes, they do have "magic ingredients". By that I mean they use levels of pigments in a specific formulation that the hardware stores simply can't match. Look, I took a properly prepped sample of CC Digital Green to Lowes and gave it to the paint department with...

    Best Material for Greenscreen?

    Go get a cheap roll of discount linoleum, 12' wide by 24-30' long and paint the BACK side of the material (first do white primer) with CC digital green or blue. Hang the roll up high and pull down what you need when you need it... a seamless cyc can be achieved with the linoleum by pulling it...

    World's first official Convergent Design Gemini 4:4:4 recorder short test

    Here are a few examples of S-Log images taken from the F3/Gemini444 combo, captured from the dual link output. I used the built in F3 log (rec709 at 800%) to save to the XDCAM 35Mb/sec onboard, while using the Gemini built in monitor to view the flat S-Log image... In Photoshop, I took the...

    Blue and Green screen experiments

    Hi all... did some tests yesterday and fiddled around a bit today with the footage. First, new info from so many folks coming in on the best settings for color, detail, noise, etc. make shooting yesterday like shooting an eternity ago. I shot some blue and green screen with -4 detail, and it...

    AF100 tungsten vrs daylight

    Whenever I evaluate a camera system, I start with the issues that impact my work, and they always fall into a few categories. First, I'm curious how the camera responds in terms of noise and image structure, followed by how to define the best sharpness settings, and then how it performs for...

    EX1 and RED playing nice together...

    Hey, it's a better title that "EX1 vrs. RED" or somesuch, as I think you'll be happy with whatever camp you're coming from after reading this. Bottom line, had the chance to do some shooting with my EX1 and do some tests against some REDs... one thing I was keenly interested in is how they...

    HP "ripoff" project with EX1...

    Hi all; Recently finished this project for the RE/MAX International Convention held last week... thought there'd be some interest despite the specialized content because it has some green screen work and of course it's shot entirely with the EX1. Directed and DOP'ed by the supervising...
