EXPERIMENTS IN BOKEH // 04.27.13

HELIOS 44 58MM F2.0 (WITH MODIFIED ELEMENTS)

I’ve been trying for a while to come up with a way to emulate extreme PETZVAL like bokeh on a EOS camera. The HELIOS 44 comes close. But I was looking for something more Petzval and less lensbaby. This is where I am at… somewhere in between. Very soft focus at the edges… Wild bokeh effects and swirls. Loads of lens flare, and something a bit like ghosting but its not… A wild beast. Be sure to watch the video. Trippy.

If I get enough interest maybe I take orders for these… email if interested… put “HELIOS MOD” in the subject.

DATA part I

The customization begins!

Like many of you out there I couldn’t wait any longer for Apple to release a new Mac Pro workstation, so I am building an editing station around the new Macbook pro. Not a fan of Apple’s 1.0 releases, I decided to skip the retina Macbook and opted for the near identically specced and fully upgradable Macbook pro 15”.



STEP ONE: Removing the DVD drive and adding a 480GB SSD. I plan on using this as an onboard “work” drive. I pulled out the spec Apple SSD and replaced it with OWC 6G 480GB SSD. I place the OWC SSD in the main slot and placed the Apple SSD in the DVD drive bay. I used this configuration because the dvd drive throughput isn’t always operating at 6G speeds. The SSD configuration operates as fast as a RAID. I am getting 500+MB/s performance.



With no RED camera support in the current FCPX release I am giving Adobe Premiere a try, and so far I am loving it. With the internal SSD work drive I am getting real-time playback of 5K footage at 1/4 resolution. After editing I am exporting XML and opening my edit in Redcine-X Pro for first light color correction, then jumping into After Effects to do final grading and FX. A very nice workflow indeed. No rendering no trancoding, very nice. I only wish Adobe would support RED CODE 3, but they have been on top of things so far so I imagine it’s right around the corner.

STEP TWO: Adding PCIe expansion to the Macbook Pro. Since Apple has done away with the express slot, that leaves the thunderbolt as the IO of choice. I’ve opted for the Sonnet Echo Express Pro thunderbolt PCIe chassis. I will be testing a few difference configurations to see how much thru put thunderbolt can deliver. The Sonnet Echo Express Pro offers 2 4x slots for full sized PCIe cards. I plan on testing 3G, 6G ATTO MINI SAS RAIDS, LTO5 Tape backup and a RED ROCKET CARD. I will post data rates and transcoding times for each config in PART II. Theoretically I should be able to hit some pretty crazy data rates but we will see what bottle necks are in the system.

I am optimistic looking forward.

Aerial Recon Lens on 5Dmkii

A 7 inch (178mm) f/2.5 Kodak Aero-Ektar lens removed from a K-24 aerial recon camera. Custom focusing helicoid and extension tube. Have to upgrade the focusing mechanism to have a longer throw.



Heavy, next to impossible to focus, D-R-E-A-M-Y. Has a massive image circle covering 5x5. More images soon.
