I’m have a ball with my new hot lights. The vintage portrait project is coming together as I work out how to use the lights, get Lightroom and Photoshop to rework color to black and white and get a good workflow down. I’m also relearning how to shoot film as part of this project.

So the last entry on this subject was about shooting with a single light and this week, I’ve taken it to two lights. The idea is to provide some fill and highlights. And lest you think that one needs an expensive studio or alot of room for this style of shooting, that could be further from the truth. The sample shot I have included this week was taken in a 5×5 space right in front of my front door entry way with some white polarplus gaf-taped to the wall. Pretty low tech if you ask me.

So here is the “studio” shot. I have used my Wacom to mark it up a bit. As you can see, not very high tech at all or expensive.

But the results you can get are pretty amazing. I used Lightroom and Seim’s Power Workflow 3.0 Snapped B/W as my basic conversion from color to Black and White. I’m not sure if I’ll stick with this one but it’s a starting point. I then moved it into CS5 and used Focht’s Touchflow Palette to smooth out skin and add a touch of pop. I also used my Wacom to paint in and paint out extreme shadows, hot spots and such.

Not bad for the price of a doorway studio huh? I’ve found a book at Amazon called Hollywood Portraits: Classic Shots and How to Take Them
which goes into quite a bit of detail in how the old school Hollywood shots were created so that has been ordered. I’ve also ordered up Nik’s Silver Efex kit since it’s on sale at Adorama for a killer price. And yes, it soon will be 64 bit which makes those of us running 64 bit Photoshop very happy. You can download a free 15 day trial from Nik and give a workout to see if you like the outcome but I have to say, it makes some really nice B/W conversions.

I’ve mentioned the clone of the Arri lights before but here are the real deal if you are inclined or feel more comfortable with the brand named item. This can be very important if you want to rent out the kit as grip equipment or the like. This is the complete kit with 3 650 watt lights, roller bag, stands, barn doors etc.

One of my newest projects is ramping up to offer old school style of portraits in the Hollywood Glamour and Noir style. This type of portrait was made famous by photographers such as George Hurell in the 30s, 40s and 50s.  They were a very dramatic black and white picture with very distinctive light and shadows. Many times these were shot with fresnel hot lights that normally would be used to shoot movie films. Many folks have tried to reproduce this style of image using strobes, snoots and reflectors. But while these can get close, the old school equipment has some unique qualities that add subtle but very important changes to the image.

Hollywood Hotlight Glamour

Lets take a look at the one of the biggest difference between shooting with continuous lighting vs. shooting with strobes. Many photographers of the digital age have no idea what a hot light (I’m referring to continuous lighting here)  is since all they know are strobes. In their mind, who would want to use a light source that is big, bulky, can run very hot (unless shooting fluorescent bulbs ), need AC power, barn doors, scrims, dimmers and more? The “disadvantages” are many in most photographer’s minds.

There is one very important detail among everything else that the hot lights excel at. And that is the small fact that since the light is continuous,  you can shoot as fast as you can hit the shutter. So when the model hits her/his stride in providing the EMOTION of the shot, you can catch it without fear of the strobe being in the middle of recharge cycle. Most strobes require a second or two to recharge unless the photographer is shooting with multiple strobes and the power levels dropped down to encourage the faster recharge rate. Or the photographer is shooting with very expensive packs that can recharge very fast. Either way, speed costs money, how fast do you want to go?This does not really apply if the photographer is shooting posed shots where the model is set in place and needs to hold that pose specifically, I’m talking about the more organic style of shooting where the model has some latitude on the pose. In the static poses, you can afford to wait the 1-2 seconds between pops of the flash since the model’s job is to stay still till told otherwise.

Other points in the hot light’s favor, in particular, in the fresenel’s favor is the ablity to focus the beam and that the light is fairly constant over the diameter of the beam. Also,  the beam has a naturally soft edge which is great for feathering the light on the subject and the ability to very quickly and easily adjust the shape of the light with barn doors. All of this leads to a very flexible lighting solution for portraiture shoots.

One more possible advantage is that with the hot light, the photographer does have to work around the model flinching every time the strobes fire off. This is not always the case, a model used to strobes would not normally  have this issue but a new model or someone who is a non-professional paying client will not be used to the bright strobes firing off in their face every few seconds.

For my glamour project, I looked at different brands of fresnel hot lights because I really wanted to recreate the old school hollywood glamour and noir images. So I went back in time a bit and decided I would use equipment close to what was used then for my lighting. I had tried strobes and I was not at all happy with the results. What really changed my mind was a shoot I went to a few months back that used hot lights and I had very little experience then with hot lights. I had grown up on strobes so I was really curious to why we would be using such old technology. I know that the film industry used continuous lighting but I could understand that but why use them with still photography? After shooting for a few hours and seeing how I could catch very small but critical changes in pose and expression, I got it.

So I went shopping to find some hot lights of my own. I could buy used lights but the bulbs can be very expensive if you dont know what you are buying but ARRI lights are bucks. I found some ARRI clones on eBay but over at Coollights, I found the same basic clone ARRIs, scrims, nice air cushioned stands, barndoors and a good quality roller case as a package deal. The ARRI package was 1800 and Coollights package was 1,100 USD. So for a savings of 700, I have what is for all intents, three ARRI 650 frensel lights, stands, scrims and case. The big difference is the stand mount, the cut edges are not as cleanly cut as the ARRIs and the aluminum is not beaded and coated. I can live it for now. I have pictures below of both lights

So what you do with hot lights? Set your white balance to tungsten and rock and roll. One piece of advice, get a light meter. It’s far easier to meter tungsten then trying to chimp when you have ratios of lights. I also bought 3 cheap speed controllers from Harbor Freight which are perfect dimmers for the hot lights to get the lights right on the money in intensity without having to move anything. Also get some toughspun for diffusing the light.

This shot was taken using a set of ARRI 650s. The shot below was taken with the Coolight ARRI clones. I could not find any difference in shooting with them or in post with them.

Above all, be careful and make sure everything is secure on the set. Use sand bags and plenty of gaffers tape to secure everything down. Hot lights are, well, HOT.. very hot and will remain hot for several minutes after you turn them off. Keep in mind your model is baking under the hot lights and so breaks every 10 minutes or so is the norm. It’s also very hard for a model to look directly into a hot bright light so dont think you will put a light head on and have the model gaze into it.

A parting trick is to get the 650 hot lights and then put in the 300 watt bulb if the 650 is too much all the time. You can always do down in wattage but not up. Also, using a dimmer to cut the output by 20% or so can give the lamp about a 50% increase in lifespan. The bulbs for the ARRIs and clones will set you back about 15-20 USD and they are rated at 200 hundred hours when used at full power. Never touch the glass of the bulb with your skin, the oil will cause the bulb to get a hot spot and burn out very quickly.

Faster, everyone wants to go faster, have a faster computer, a faster disk drive or a faster application. Once a VERY expensive option, the SSD (Solid State Drive) drive has become mostly affordable now they are being made in large volumes. You can get them in all kinds of packaging so you can put the drive into a PCI-E slot or replace an existing hard drive. The most common use for photographer is either as a extra volume or a replacement system volume.

Before we look at the speed of a the SSD, we need to understand how they work and what makes them differently than a traditional hard drive with a rotating plater. The traditional hard drive for years has been made with a motor of some kind spinning a metal or glass platter(s) in a rigid cast metal chassis. They were heavy, took a fair around of electricity to move the platters and it took time to move the heads across the platters. Over the years, the motors were improved, the platters were made lighter and higher capacity and throughput was improved with the new interfaces like eSATA (enhanced  Serial Advanced Technology Attachment) and SAS (Serial Attached SCSI). But even with all the improvements such as 15K RPM drives, glass platters, low power electronics and very sophisticated storage algorithms, they were still a very slow device  when compared to the lighting fast access times of a memory chip.

But memory chips had some issues like they lost their contents when the power was removed and they were expensive in the number needed for any decent capacity. Time passed and now we have FLASH based chips that keep their contents even with power removed, we can write thousands of times to the same locations without the memory location burning out and they are cheap enough we can build an array of chips to supply a reasonable amount of capacity on par with the traditional hard drive.

This brings us pretty much up to date where we can buy a 240 gigabyte SSD drive in an external case with Firewire, eSATA and USB interfaces for about 500 USD. You can buy a bare 500 gigabyte SSD drive with an eSATA interface that drops in as a replacement hard drive for about 750 USD. But why you ask? why spend four times what it costs for a 1 terabyte hard disk drive? In short, SPEED.

The SSD is very fast compared to a normal hard drive, there are no moving parts so the drive is immune to shock therapy and it can be easier on power but not always. Most of us are into the speed for our applications.

For example, I have a 240 GB external SSD from OWC attached using Firewire 800 to a dual quad MacPro tower. My testing of Photoshop, Lightroom and overall usage like file copies showed some very interesting results.

  • VMware Fusion booting Windows XP takes 22 seconds from power on vs. 1:20 for a internal HD
  • Copying 55 GB of data from the MacPro to the external SSD took 19 minutes
  • Photoshop CS5 starts in 17 seconds vs 22 seconds. This does not seem like much till you start using it. Then the speed becomes very apparent between loading large files or files with alot of layers and/or high resolution. It also becomes very apparent in running actions and working with video files which means moving larger chunks of data to and from the disk.

Now the downside to the SSD used to be  the limited lifetime usage of the NAND chips. But that has been overcome to a large degree by over-capacity and by “data leveling” where the data is written out to ALL the chips over time instead of the same group time and time again which is like a traditional hard drive.Each memory location is rated at something like 100,000 writes. However, the cheaper SSD drives are not created equal and one of the corners cut is the over capacity and data leveling.

Where do SSD drives really shine? on the random access times for data. The typical read time is 0.1 ms vs. the 10-15 ms for a normal hard drive which has to move the heads to where the data should be and then wait for the platter to spin around and put the data under the heads. Random access for small files is the key place of performance for the NORMAL user of SSDs. All the bandwidth and throughput of large files is fine but on your computer, it’s mostly small files in random places on the hard drive. If the drive can not perform in this area, you will be hating life and the new SSD that you just spent a ton of money on.

Even the best SSD drives have a limited life time so using them for swap files space is normally a bad idea since the data constantly changes and is rewritten. But for the typical system drive or scratch drive, the SSD can work very well for two or three years of normal use. Any SSD drive will slow down some from the initial speed but they will still be faster than a normal hard drive spinning a disk platter.

If you are a geek and want alot of geeky details on SSD drives, performace and how they really work, check out ANANDTECH and the article I’m linking to. It’s a really good piece of detailed information on SSD drives.

Is this short blog entry a definitive article on SSD drives? not a chance but it should show you that an SSD drive is probably the number one way to improve performance on your editing workstation all the way around. Now days processors are so fast that even a two year old mid line processor is pretty good and ram is so cheap that most systems are now spec’ed with a decent starting point of RAM. So the only real bottleneck to your workflow is the disk I/O speeds. The SSD addresses that in several places and can really boost your output.
