My Shots from Friday's Shoot

Okay. I didn't get to shoot medium format digital. But, I did shoot. Here are some shots from Friday with the Leica R9/DMR. All the headshots are done with the Leica 100mm APO-Macro. The other shots are done with the Leica 28mm Elmarit. That 28 just has no visible distortion. Both are sharp as a tack and really easy to focus. Keepers for sure. All lighting was from Elinchrom Ranger RX battery-operated studio strobes. The pictures were shot in the order they are displayed. For more explanation and insight, be sure to check out the behind-the-scenes entry below.

Medium Format Digital Backs at the Beach

Friday we arranged a shoot. Chuck Jones from Mexico was in town on vacation. He and David Kipper had just picked up matching Leaf Aptus 75 digital backs to go on matching Contax 645 cameras. Craig Hildebrand from Fort Myers drove across the state to bring his Hasselblad 501CM with Imacon 528C back. David came down from Melbourne.

Andre and I arranged the shoot. We got some great models, Rachel, Chantal, and Oona, as well as a great makeup artist, Valerie. Craig brought an assistant. Meir Israel joined us so he could experiment with his Rebel XT he had converted to Infrared. Amy and her daughter Alex were also slated to join us. Needless to say, we had a lot of people. We also had a ton of gear.

Besides the three medium format setups, Chuck and David both brought Leica R9/DMR setups (one of which I ended up shooting), Meir brought his Canon 1DsMkII and lenses. Chuck's wife had a Rebel XT. We brought along a D2X for behind the scenes shots, and I ended up leaving my 503CX in the car in the vain hope of trying out the 528C back on it. And then there was the lighting gear. Between all of us we had four Elinchrom Ranger RX Speed AS packs and three Profoto 7B packs. I can't even remember how many heads and ringflashes we had. Add in to the mix half a dozen steel lightstands and assorted light modifiers and we were carting around a circus. So, was the greatest show on earth worth it?

Before we left Dale Photo & Digital to head out to the beach, the sky just opened up and the rain came down. Summer in Florida. We waited it out, about an hour, then the sky turned bright blue, and we made our way to the shore. Spent another half hour just getting gear unloaded from all the vehicles.

Deciding where to set up

Because the models had to leave at 3:00PM and it was already noon, I decided that I'd start shooting. Did a quick setup with Chantal while Andre got Chuck and David set up at a different location. I was keeping things simple. Just using David's R9/DMR with our 28mm f/2.8 Elmarit and 100mm f/2.8 APO-Macro. What I didn't do was check that the camera was set to manual and not aperature priority. I got lucky and the lighting setup I had chosen played well with the ambient light, but I'm still a bit miffed at myself for making such an oversight. I did make the change in the next setup when things looked off on the LCD. Saved by digital.

While setting up for shooting, a few things became clear. The Contax 645 (and others, like the Mamiya 645AFD) have a flash sync of 1/125th. While this is fine in studio, we were curious to see how this would play out in the big room (outdoors). Sure, they could shoot ISO 50, which would save them from having to stop all the way down to f/32 or f/64 just to get the same as f/22 on the DMR/D2X/30D/RZ67/503/etc. But, this required twice the power. I figured in order to achieve 80/20 lighting ratios or better, they'd need to use full power on two packs and shoot at 1/125th at f/22, ISO 50. I could get the same look shooting at 1/250th at f/22, ISO 100. Remember, in terms of light, you need double the light to equal one f-stop.

For Chuck and David's first setup with Rachel, this is exactly what they ended up doing. Even with the fast recycling on the Elinchrom and Profoto packs, three seconds can seem like an eternity.

Another interesting quirk of the MF back came up in that first setup. The Aptus 75 has a huge 6 by 7 cm screen (3.5" LCD). It's a touch screen, creating a very flexible and changeable interface.

It is invisible outside. The guys had to run to the bushes and hunt shade to see their LCDs. Not just for chimping, but to format cards and change settings. If it were me, I'd expect a little better screen or anti-glare coating for $30k. Leaf said they are working on some type of hood to help the situation. Of course, the DMR screen is just as clear outside in bright sun as it is indoors. So, no problem there.

Then, the rain came again. We all ran for cover. Chuck's Elinchrom head with 27" beauty dish came crashing to the pavement. And of course, the Ranger packs got soaked once again. No major damage, except for a little dent in the dish. Love the Swiss.

A few minutes later, the rain was gone, the sky was great, and we were off shooting again. Everyone except me went down to the ocean.

I stayed and worked the location. A while later, the troop came back to base camp. Craig had a wave get up close and personal with his Imacon. Meir was wet from the waist down. Everyone was hunting for bottled water. It was extremely hot and ridiculously humid that day. I finished up the last headshot of Oona and we packed up the gear and headed back.

A/C and cold bottled beverages were apt rewards for a crazy day in the sun. We headed up to the conference room at Dale, whipped out laptops, and started looking over the day's work. Meir's infrared shots were pretty freaky, and I was happy to get some good shots.

Some lessons learned:
  • 33MP is a lot of detail.
  • The DMR and the 100 Macro are still a force to be reconned with.
  • Don't forget bottled water (I did) or sunscreen (everyone else did).
  • 17lb Elinchrom packs, while not feathers, weight a lot less than 26lb Profoto ones. 9lbs in 90+ degree weather feel like 90lbs.
  • Assistants are nice to have.
  • Maybe think to bring an umbrella of the non-lighting kind.
  • Hasselblads have 1/500th sync speeds and that's a good thing.
  • Clean the sensor before shooting and save a lot of Photoshop.
  • Too bad Andre and I didn't get a chance to shoot with the MF systems, but that's already in the works.

Dell Precision 490

Okay. So I was supposed to be working on posting images from Friday's shoot with David and Chuck, which I promise to still do. But, today the UPS man was my friend, bringing me the Dell Precision 490 over a week earlier than Dell told me it would even ship. We'll be using this system for Kodak DP2 rendering, so I thought I might run some CPU benchmarks.

This thing is fast. And I mean crazy fast. I ran Super Pi to 1M (1 million digits of Pi) in 17 seconds! 2M ran in 46 seconds! Let's put this in perspective. The latest and greatest MacBook Pro runs 1M in a squeek over 30 seconds. Simple math tells me that this is roughly twice as fast, as in 100% faster. Woah. Here are some SiSoftware Sandra CPU benchmarks for anyone interested. And for those who want interperations of the numbers, this machine just plain clobbers everything out there.

This workstation runs up to two Woodcrest (Xeon 5100 series) processors. We only have one installed, running at 3.0GHz with 2GB of quad-channel FB-DIMMs at 667Mhz (Fully Buffered ECC). For storage we got two 250GB SATA drives in RAID 1 configuration. For those who want to get ultimate performance, this workstation uses the new SAS (Serial Attached SCSI) drives in various RAID configurations.

Compared to a Conroe (Core 2 Duo for desktops), the processor is almost identical, except for the ability to use two of them and at a higher FSB of 1333Mhz vs. 1066Mhz for Conroe, as well as supporting a quad-channel memory architecture. Also, the Xeon clocks higher.

A few comments about the machine. First, it's built really well. All metal chasis. Easy "tool-less" access to everything inside. Lots of ports. Support for eight FB-DIMMs for up to 32GB of RAM. Suprisingly quiet. You have to really put your ear up to the case to hear anything. Also suprisingly cool. Putting my hand over the rear exhast vent for the processor cooling fans, my Core Duo laptop feels just slightly hotter. The exhast is practically room temperature.

The computer overall is super-responsive. Programs, windows, whatever launch instantly. This is hands-down the fastest system I have ever used. What amazes me is why nobody is posting any kind of Photoshop benchmarks for Woodcrest systems. Everyone is focusing on Conroe, which is only single processor. For real power users, this system should be at the top of anyone's list. With prices well under $2000, I'm starting to think twice about a Merom (Core 2 Duo) laptop. Is the 490 portable? No. Is it fast? Oh yeah. Decisions, decisions.

Tomorrow, I'm going to try and run some Photoshop benchmarks. If anyone has any photos or filters/actions you want me to run, post a comment. I'll do my best to accomodate. So I bid my new toy farewell for the evening and head home, hopefully to get cracking on posting Friday's shoot. Look for it.
