Studio Flash

Money far better spent than getting yet another lens or camera.

I have always been a fan of the great state of Texas. In addition to providing drivers with cheap oil in any number of distillations concocted by corrupt state politicians earning their kickbacks, any state that has a predilection for frying bad guys rather than giving them three square a day, air conditioning, free bed and board and color television for upwards of fifty years, has to deserve the respect, admiration and gratitude of the taxpayer.

The addition of another fine product from that great state, a Novatron studio flash outfit, to my small equipment cache a few years back, only served to confirm my love of things Texan. The flash heads in that kit proudly proclaim ‘Novatron of Dallas‘. Go Cowboys!

Who needs studio flash? Well, anytime a portrait beckons or a still life has to be just so and heat is not to be a factor in the equation, studio flash is the ticket. Your Coke-bottom lens, well stopped down to cope with the powerful light output, suddenly becomes a Summicron, Planar or Canon ‘L’ – and the flash outfit will likely run you far less than any of those magnificent optics. Camera shake is a thing of the past. The light duration is very short, after all.

Too bulky, you say? Don’t have studio room, you grumble? Nonsense.

Here’s my kit, with that sophisticated man about town, Bertie the Border Terrier, providing scale. (Modeling fee? 1 cookie).

What you see, in addition to that fine canine specimen, is a transportable case containing three Novatron 500 watt flash heads, three tripod stands, the power pack and some long flash synchronization cables, as well as two silvered umbrellas which attach to the flash heads when shadowless lighting is called for. I used to pack an electronic flash meter also, but that is no longer needed with digital. Pop off a couple of snaps, check the LCD screen in the camera and correct exposure is assured.

The 500 watt-second heads in my kit are discontinued, replaced by 600 watt-second ones and, as with mine, these include ineffectual modeling lamps to purportedly help you assess the effect of the lighting. Once again, that LCD screen in your digital camera does a superior job. Better still, tether your Canon EOS digital using the Canon EOS Capture utility (maybe Nikon and others make something similar – I don’t know) to a laptop and you will really be able to judge your lighting. That estimable vendor of photo gear, B&H, lists a three head 600 w-s Novatron kit for some $900. A bargain and all the power you need for the home studio.

The heads on mine have three position power switches and I usually use them on 1/4 or 1/2 power, which gives a recycling time of some 2 seconds when all three are in use. One is a main light, the second a modeling light and the last a background or hair key light. For the latter, a small tripod/boom-arm made by Manfrotto, suitably counterbalanced with a sand-filled sack, (high tech at work), is suspended above the apprehensive subject’s head. You too can make out like George Hurrell – he even managed to make Judy Garland look attractive!

Now while more modern units integrate the power pack and flash tube – thus unnecessarily increasing bulk and cost while trading both for looks – you still have to run power cables with either, so what’s the big deal? Further, some seek to add to the cost by using a wireless connection between camera and power pack. There’s something in that as it obsoletes one cable, meaning one chance less to trip, but there are already so many of those I have never been tempted by the additional outlay.

If your camera is an older Leica, like an M2 or M3 with those superb sturdy flash contacts, there’s no need to compromise with a cheesy adapter to take the standard 3mm coaxial connector that bedevils the flash reliability of cameras thus equipped. Just go to Paramount Cords and get a cable terminated with the connector of your choice. The other end? The Novatron boys, bless ’em, use a simple, cheap and very sturdy household ‘H’ plug! Must be all that experience they have in Texas with high current loads in their correctional institutions. I wouldn’t bother with those coiled cord wonders either – a problem waiting to happen. As for choice, well how about the old Nikon push lock, Koni Omega (remember them?), old Leica M (tip #30 if you must ask), Rollei locking (great for that 3.5F or 2.8F), and many more?

Users with modern digital cameras with fragile internal flash contacts worry about trigger voltages – the amount of voltage transmitted through the camera’s flash contact when the flash is triggered. Most recommend that 9 volts or less (the Canon EOS 5D allows a whopping 250 volts!) is the safe way to go. Well, you can measure the trigger voltage of any flash unit with a voltmeter and two fine tipped probes. Charge up the flash and touch the probes to the two flash contacts. My ancient Novatron kit comes in at 6.4 volts, falling to 2.5 volts if a Wein Safe Synch is fitted between power cord and power pack. By the way, my fairly recent (Chinese) Vivitar 283 portable flash unit comes in at 10.1 volts, though I understand some of the earlier Japanese ones could really fry things. Motto? Check your camera’s instruction book and use a voltmeter first, to be on the safe side.

Now $900 may seem like a lot – about the cost of one more unnecessary lens for your camera – but I have found the utility value and payback from my Novatron to be excellent. Whenever I wanted to take some studio portraits I would rush to the local pro-dealer, leave half my net worth and Border Terrier behind as collateral for the loan and pay a weekend fee which was invariably over $100. A few of these trips and several things dawned on me. First, I was wasting time and gas on all those trips. Second, it was getting expensive. Third, my credit card record was getting messed up because the clerk in the store had an IQ in single figures. Fourth, I missed my dog! Finally, I was restricted to weekends, as the weekday rate was ruinous and things far too rushed.

Thus, I reckoned, the first nine times I used the Novatron now in my hall closet, it had paid for itself. And my credit score improved too.

For still lives it’s a killer set-up, for you know your lighting is cool and constant, nothing fries and all is repeatable as you concentrate on composition.

As for studio work, you be the judge.

When a plain background is called for, by the way, I use a Photek Background-in-a-Bag. You crumple the cloth and separate the poles, stashing the lot in a small canvas bag for transit, placing the background cloth in a clothes drier for a few minutes before use, to get the wrinkles out. Some $120 for the 6′ x 7′ model, which is more than adequate for head and shoulders portraits.

So my two cents’ worth on the matter are that a studio flash outfit should be a serious consideration for anyone seeking to make quality studio portraits, picturing interiors or doing still life work.

And if the only flash connector your camera sports is a hot shoe, no problem. Just splash out $20 on a Nikon AS-15 hot shoe adapter and your point-and-shoot has just become a studio camera. I use the AS-15 on my Canon EOS 5D rather than messing about with that silly flap that stubbornly refuses to disclose the coaxial socket. B&H continues to list this great little gadget.

Finally, if you are concerned about obsolescence, my twenty year old Novatron outfit, for which parts continue to be abundantly available (though it is as reliable as it gets), works every bit as well with my EOS 5D as it did with my 4″ x 5″ Crown Graphic. I bought my kit used some ten years ago and have had no problems with it. When they go out, replacement flash tubes are cheap and heavy, professional use will likely dictate new capacitors in the power pack now and then. It’s not about to go out of fashion, until the folks at Apple work out how to pass vast amounts of current through the air without connecting cables.

HP DesignJet Z photo printer

Brought to you despite the Board of Directors.

If you have been following the financial news recently, you could be excused for thinking the Board of Hewlett Packard couldn’t organize a booze-up in a brewery. Depsite the twits in the corner office, the great engineers at HP continue to make innovative products. The most recent announcement is the HP DesignJet Z photo printer.

Long time readers of this journal will know how pleased I am with my HP DesignJet 90, which will make up to 18″ wide prints using fade-resistant inks. Having made some forty 13″ x 19″ and 18″ x 24″ prints in aggregate over the past six months on mine, ink levels remain astonishingly high – if those meters are linear this has to be one of the most economical printers available. Three cartridges are still showing full, the other three three-quarters full. Print quality is as good as it gets.

The new floor standing DesignJet Z comes in 24″ and 44″ widths and is focused on extreme color accuracy, courtesy of a built-in Gretag/Macbeth/X-rite spectrophotometer to automate paper profiling and ICC profile generation. I use an external version of the X-Rite to profile my screen and then adjust the ICC profile manually for the paper used with HP’s provided tools, as I explained in my review. Well, now the need for tortuous manual ICC paper profiling is gone. You can get some idea of HP’s target market by looking at the picture above – that looks like a photograph of a Tissot painting in the printer on the left.

These are not cheap. The base 24″ model will sell for $3,400, compared to $1,300 for the six ink 24″ DJ130. The price of the new printer compares favorably with that of the 24″ Epson 7800 at $3,000. The new DesignJet will come in eight or twelve (!) ink models, so you can see how totally focused HP is on color fidelity. As a point of reference, my six ink DJ90 goes to 18″ wide and sells for $1,050. This will be a great machine to fool all those Label Drinkers. Just tell them the print was made using traditional darkroom techniques, just like Ansel Adams used.

Which just goes to show that no matter how disfunctional your Board of Directors may be, you can’t kee a good engineer down.

Multi-media rocks!

What’s a web presence without sound and movies?

As my horizons have widened and simple creation – aided by great Mac software – has made establishing a sophsticated web presence far easier, I find myself reflecting as to why so few photographers’ web sites are silent. And stationary.

Adding sound is very easy with free tools like Audacity and inexpensive (if overpriced) digital sound recorders like the Edirol.

By way of example, a fellow photographer started working with me on a photo book some six months ago. What started out as a hard cover picture book has gestated into a web-based eBook with pictures, sound and QuickTime movies. Now which, for a photographer, do you think is more compelling?

True, it’s still not as easy to ‘leaf through’ an online book, despite advances in laptops, as with a hard copy tome, but then I don’t see how you can enjoy sound and movies in the latter.

Stay tuned for our upcoming twenty-first century interactive book.

Sound memories

Sounds add greatly to memories.

The very first column in these pages spoke about the nostalgia of family albums. I could not but help being reminded of it the today when a singularly unusual thing happened.

I was rummaging about in the desk drawer looking for something when my old Sony microcassette dictaphone surfaced from the dark recesses. Seeing it brought memories flooding back. Not of all the times I had used it in business to dictate cover-your-rear memoranda in the world of corporate politics. No, that is mercifully forever behind me now. Rather, I recalled that the last time I had put this great, if now very dated, analog tape recorder to use was some three years ago when our son was but one year old. He used to hang out in his crib and merrily squeal to himself as he discovered his vocal chords. So I had switched it on ‘record’ and placed it in his room under the crib, so he could chat away undisturbed.

Coming back half an hour later, sure enough, there were several minutes of squealing and general joie de vivre on the tape. I put it back in the desk drawer and pretty much forgot about it until it surfaced again today. Now with my new awareness of the value added by sound to my photographic efforts, it immediately occurred to me that the tape had to be somehow recovered and placed on the family web site, next to the snaps of our son. This proved trickier than you would think.

You see, the tired old tape, used who knows how many times, decided to come off the end spool when I rewound it. Now these cassettes are not rebuildable, being heat sealed, unlike in days of yore when they were actually screwed together. And the idea of somehow transplanting the precious tape to another microcassette was a prospect I dared not contemplate. Why not buy a regular tape cassette and splice in the tape from the microcassette? And she was right – the tape sizes are identical and I had always used the 1 7/8 inches/second tape speed on the Sony for best quality. That’s the same speed regular cassettes run at.

Off to the local Target store where, to my dismay, I was hosed down for no fewer than ten cassette tapes, individual ones no longer being sold. Still, at $7, the damage was bearable, particularly given the importance of my mission. Back home, I pulled out enough tape to make room for the spliced section coming from the microcassette, managed to get hold of the tape pigtail in the latter, and glued in the whole tape with superglue, winding it in laboriously with a pencil through the hub….analog to digital was never so difficult.

The next step was to track down a tape cassette player – our tape cassettes exited stage left years ago. Then it occurred to me that I had an old boom box in a guest room and before you could say ‘yipee’ I had the tape playing on the boom box with my Edirol digital recorder placed nearby.

Into Audacity with the MP3 file, a few moments later a noise sample was made and the noise filtered out (Audacity is great!) and our happy son made his way to the family web site for all to enjoy. They’re just squeals to you, so I will not repeat them here, but for us it’s a wonderful enhancement to our memories of Winston when he was but one year old.

So when you take pictures of your kids, why not record the sounds they make too?

A related lesson is to digitize all your old media – records, tapes, pictures, because before long it will be impossible to get the playback devices these need. Plus, backing-up of digital is very easy.

Always carry …. a sound recorder?

A new twist on an old saying.

Which of us has not heard “Always carry a camera”? The exhortation is rarely informed, of course. Any Englishman will tell you that it never rains when you carry an umbrella, and for most, the same applies to cameras. You never see good pictures if you just happen to have one along for the ride. Good pictures are made, not found.

However, just to put a new twist on it, how about “Always carry a sound recorder”?

This past weekend I was with our four year old at a local park and, as is the case with kids, Winston made straight for the play area. This, you must understand, is fenced. Not to keep anyone out but rather to keep all those threats to society, little children, in. And no, this was not in the Bronx or Brixton. The reality, I suspect, is that one of the city councilmen just happened to have a relative in the fencing business and …. well, you know how the rest of it goes.

Well, Winnie was struggling with the latch to the gate so I gave him a hand, only to be met with the most appalling squeaking as the gate opened. Payola for the gate oiling program must have been missed this year, I suppose. But the emotion I felt most was one of excitement. This was a fantastic sound effect! So I whipped out the Edirol sound recorder (from its newly acquired 99 cent canvas case found at Target – Roland being too cheap to supply one) and had at it with the gate, much to Win’s amusement. We whanged the gate back and forth a few times and had a jolly old time doing it, I must say. Creepy! Adults like funky sounds too!

I had already added wind howl sounds to the Piedras Blancas motel QTVR picture but this project just called out for a creaky gate sound to complete the feeling of desolation. It was a moment’s work in Audacity to superimpose the squeaky gate on the wind howl and then to parcel the whole thing up in CubicConnector.

Here’s how the sound tracks look in Audacity – the wind howl is at the top. Subequently I copied and pasted the squeaky gate to match the length of the wind howl then told CubicConnector to loop the whole thing:

Now I’m not about to lug the Canon 5D/KingPano head/Linhof tripod with me wherever I go, in the search of new panoramas. But the Edirol may just make the trip.

A few words about this old motel. It has been on Highway One, close to Hearst Castle for as long as I remember. Back when I first saw it on my inaugural drive up the most beautiful road in California – that would have been 1979 or so – it was replete with gas pumps and was a hive of activity. A half decent restaurant and those same jolly white and electric blue colors. Then over the years it began to fail. Nothing wrong with the location, just lousy management and marketing. Finally, last year, the State of California bought it for an obscene amount of taxpayers’ money and promised to convert it to an educational institution, whatever that means. After all, this is the state that made America’s best public schooling system into the worst in a short twenty years, so it’s not as if they can claim to know anything about the subject.

A year later what you see is what is in my picture. A couple of old paint buckets sit outside the deserted main entrance. Weeds grow everywhere. The gas pumps are long gone and a couple of abandoned cars soil the parking lot. It’s an incredibly sad scene. Desuetude and detritus in this otherwise pristine area, with a brown State of California sign ‘Closed for Restoration’ tacked by the doorway. That’s a sign that needs to be posted on the Capitol in Sacramento.
