Fazal Majid's low-intensity blog

Since Gizmodo isn’t going to ask me that question anytime soon, and since I haven’t written a blog entry in all of September yet, I have decided to take matters in my own hands.

I carry the following in the pockets of my jacket:

• PalmOne Zire 72: far better ergonomics in practice than my previous Sony Clié UX50
• A pair of Maui Jim sunglasses (changed recently from a pair of Serengeti driver’s). The shades are polarized and mirrored to minimize glare, and have an incredibly flexible and lightweight “Flexon” nitinol memory-alloy frame. I got mine in bronze tinted glasses — they are also availabe in a darker neutral gray, but the warmer tint was more comfortable.
• A Sony-Ericsson T68i cell phone, somewhat dated but perfectly functional (this means a synchronized phone book thanks to iSync). It alsod provides my Zire 72 with Internet access via Bluetooth and GPRS.
• A PQI Intelligent Stick 256MB USB flash drive, small enough to fit in my wallet
• Three fountain pens in a leather case, a Montblanc Meisterstück (Aurora black ink), a Waterman Edson (Herbin Vert Pré green) and a S.T. Dupont (Private Reserve Naples blue).

My gadget bag is a Tumi expandable messenger bag. It holds:

• Contax T3: This diminutive 35mm film camera has a superlative Carl Zeiss 35mm f/2.8 Sonnar lens. Compact digital cameras are based on small sensors with high levels of electronic noise, and are totally unsuited to low-light shooting in available light.
• A Pedco Ultrapod mini folding tripod with a built-in ball head. Small and light, but quite versatile.
• Leica Trinovid BC 8×20 binoculars: these ultra-compact folding binoculars have excellent optics and can be used by eyeglass wearers thanks to their innovative fold-out eyecup design.
• A Moleskine pocket notebook
• An Edmund Optics Hastings triplet 10x folding magnifier, with high resolution and excellent achromatic correction.
• An Alumicolor pocket architect’s scale, metric, of course, and a self-winding tape measure.
• A Faber-Castell e-motion mechanical pencil: its thick 1.4mm lead makes it glide across paper and its cigar shape is very ergonomic.
• Surefire L1 LumaMax LED flashlight: I used to have mini Mag-Lites, but these flashlights, derived from military and law enforcement versions, have much more power (two beam intensities) and an even beam without dark spots. Ideal for reading. The only downside is they run off Lithium batteries, which can be hard to find (but Surefire will sell them to you in bulk at a significant discount).
• Apple iPod 15GB, with either Etymotic Research ER-4P or Bang & Olufsen earphones. The in-ear Etymotics offer significant passive noise suppression (ideal for airplane use) but are dangerous to use in environments where you need to hear some ambient noise for safety reasons, like when you are in the street. Ordinary earphones like those supplied with the iPod don’t stay put, the clip on the B&O ones will keep them in place. They also have excellent efficiency and sound quality.
• Böker Orion Ti-Carbone pocket knife. The Boy Scouts were started as an imperialist means of youth mass regimentation, much like the Nazi Hitlerjügend, Fascist Balilla or Soviet Komsomol. That does not make their motto “Be Prepared” less apt, and a pocket knife is always handy. While at it, why not get a good looking one like this carbon-fiber and anodized titanium-aluminum alloy one? Just remember to take it out before a flight…
• A Socket Bluetooth GPS receiver. This tiny gizmo (smaller than my T68i) has a rechargeable Lithium-Ion battery and will last over 6 hours on a charge. Combined with the free Cetus GPS software for PalmOS, it makes a decent handheld combo that can still be used with a phone. I have yet to look closely at navigation software for the Palm.

Update (2004-09-30):

Somebody at Gizmodo clearly has a sense of humor…

Update (2005-07-10):

I have altered my standard gadget bag configuration. The messenger bag is wider than deep, and does not hug the hips well, not to mention the weight. I now use a Tumi expandable messenger bag (apparently discontinued). This bag is deeper than wide, which gives it a low center of gravity and improves handling. The flap with magnetic closures looks hip, but is in practice more of a hindrance than anything (you cannot put anything substantial in the flap otherwise it stiffens and does not snap shut any more), and I am considering getting a Waterfield Designs Vertigo instead. The bag’s liner for expansion acts as a form of padding, which is just great as I now pack either a Leica MP with a 50mm Summilux-M ASPH or a Canon Digital Rebel XT with a 35mm f/1.4L.

Many gadgets from the bigger bag did not make the cut. The Edmunds loupe, Surefire flashlight, Faber-Castell pencil did. The regular Moleskine was replaced by the thinner notebook with a soft cover. The iPod — well, the only time I ever use an iPod is during long flights

Update (2012-03-16):

For some odd reason people still read this post (perhaps this has to do with the EDC craze), so I may as well post an update.

I still use the Tumi Messenger bag for work, at least when it is raining. I have way too many bags and will use one or the other depending on the mood and how much stuff I need to carry. I have also taken to wearing Scottevest jackets, which have absolutely gargantuan capacity.

My EDC camera is a Fuji X100, that I keep in my jacket pocket. Excellent optics, high quality sensor. It’s bulkier than a Contax T3, but more versatile than the Leica X1 it replaced. I keep a Manfrotto Modopocket miniature folding tripod, although I have been testing a Gorillapod Micro 800.

I replaced the binoculars with a Leica Monovid, which is lighter, and for someone with a strong dominant eye, makes little difference.

The Moleskine was replaced with a Rhodia Webnotebook with dot grid pages. The dot grid is less obtrusive than squared paper, and the Rhodia paper from Clairefontaine is leagues ahead of the kind Moleskine uses. It doesn’t feather with fountain pens, for starters.

The Surefire L1 was replaced by a tiny Fenix E05 AAA flashlight with a nice floody beam that I keep on my keychain, along with a  now discontinued Leatherman Squirt S4 (the scissors on the S4 are way more useful to me than pliers) and a minimalist PNY 16GB USB flash drive.

The iPod, Palm, GPS and cell phone were replaced by an iPhone 4 and an iPad 3. I seldom listen to music on the go, so the Etymotic ER-4P or B&W P5 headphones more often than not don’t make the cut.

This is my first public alpha release of my feed aggregator, Temboz. It is still rough on the edges, but I have been using it with success for the past 5 months. For a taste of the user interface, you can try the read-only public preview of the last 50 articles I found interesting (opens in a new window).

Bread is the staff of life. – Jonathan Swift

Atkins faddists notwithstanding, bread has been with us ever since mankind migrated from the hunter-gatherer lifestyle to agriculture, and to urban civilization, its corollary. Bread plays an important role in religious symbolism, from the unleavened bread of Jewish Passover, the transsubstantiation of Christ and the Lord’s Prayer, or Muslim tradition according to which the cause of Adam’s expulsion from Eden was wheat, not apples. The emblem of the Nizam of Hyderabad, my parents’ birthplace, was a “kulcha”, a sort of flat bread. Legend has it, a hermit prophesied the Nizam’s dynasty would last for seven generations because its founder ate seven kulchas while the hermit’s guest.

You can travel fifty thousand miles in America without once tasting a piece of good bread. – Henry Miller

The Bay Area is gifted with a plethora of artisan bakers, preparing all sorts of delights from the Noe Valley Bakery cherry-chocolate bread, to the more touristy (but perfectly acceptable) Boudin sourdough bread. There is even a website dedicated to local bakeries (it does not seem to have been updated very recently, however). Indeed, America has San Francisco to thank for the artisan bread revolution, started by Alice Waters and Acme Bread, just as Seattle is responsible for improving coffee standards nationwide. In America, restaurant critics inspect restrooms. In France, they ponder the quality of the bread and coffee served…

How can a nation be great if its bread tastes like Kleenex? – Julia Child

What’s more, good bread is actually cheaper. The plastery Wonderbread, originally introduced by the ITT conglomerate, retails for $3.69 a loaf at my local Cala Foods, whereas a loaf of Acme’s delightfully nutty “Upstairs Bread” is a mere $2.50. Some bakeries like Southern California’s La Brea Bakery are helping popularize bread by shipping frozen semi-cooked loaves to the large grocery chains, who finish baking on their premises. While purists sniff with disdain at the technique, it is very close in quality to the real thing, and miles ahead of industrial bread.

The photography world learned yesterday the sad but not entirely unexpected news of Henri Cartier-Bresson’s demise. Cartier-Bresson was 96 years old, and had prepared his legacy by setting up a retrospective and foundation in Paris. The catalog of the retrospective is one of the finest coffee-table books you can get, by the way. Cartier-Bresson is best known for his theory of the “decisive moment”. Although some wags would say the decisive moment was really when he reviewed his contact sheets, Cartier-Bresson clearly perfected a technique of anticipating the event and being ready to capture it on film, helped in this by his Leica rangefinder cameras.

Cartier-Bresson was known for his caustic wit and his often provocative statements. In an interview to Le Monde, he derided the “academic clichés of Weston” (les poncifs académiques de Weston), referring no doubt to Edward Weston’s still life studies of peppers. Someone using lightweight equipment like Cartier-Bresson has the luxury of spontaneity large-format photographers like Weston did not. Indeed, Brett Weston, Edward Weston’s second son, quipped that “Anything more than 500 yards from the car just isn’t photogenic” when working with a 8×10 view camera.

You don’t have to carry a behemoth camera to realize the virtues of forward planning. When doing landscape photography, it is helpful to know ahead of time what kind of lens or camera to pack, and the position of the sun. There are many ephemeris tables online to find the latter, but the easiest way to select a lens is to use a map. You could use a protractor to measure angles, but they are relatively small and fiddly to use. As I often shoot with a Fuji G617 panoramic camera and a Hasselblad system, I made a series of translucent templates to help with this – all I need to do is superimpose them on the map (such as a 1:24,000 topographic map produced by a National Geographic map machine).

I wrote a quick program in Python and PostScript to produce templates in PDF format for various film formats and lens focal lengths, ready to print on a laser printer (I used Four Corners Paper IFR Vellum). I hope this will be useful. As an example, here is the template I use with my Fuji G617.

Harking back to Kodachrome

My father took most of my childhood photos (like these) on Kodachrome slide film. Kodachrome was the only color game in town for a long time, but was eventually superseded in the marketplace by C41 color print films and finer grained E6 slide film.

Kodachrome has a distinctive sharpness (acutance, not resolution), and excellent durability when stored in the dark. Many photographers still shoot Kodachrome for its special “look”, even though processing options are diminishing and Kodak jacked up the price. Kodak recently announced it is closing its Fair Lawn, NJ processing lab, the last Kodak-owned plant in the US for Kodachrome, and there are now only three labs left worldwide that can run the complicated process (Dwayne’s in Kansas, Kodak in Lausanne, Switzerland, and a lab in Japan). Kodachrome was actually discontinued for a while, and brought back after strident protests, but the writing is on the wall.

Projectors and light tables

Every now and then, we would dust off the slide projector and have a slide show. I even remember building a surprisingly effective slide projector when I was 9 using Legos, a flashlight and a jar of peanut butter filled with water as the lens. Slide projectors are hard to find, a pain to setup and most people groan instinctively when one comes up, associated as they are with dreary slide show of other people’s vacation pictures. The LCD computer monitor is the successor to the projector, and many people no longer have prints made at all, perhaps because they subconsciously realize that the 500:1 contrast ratio of a LCD monitor yields significantly livelier images than prints can achieve.

A light table is just what the name implies – a piece of frosted plastic illuminated by daylight-balanced fluorescent tubes. Basic models like my Porta-trace shown above are inexpensive. Loupes, on the other hand, are a different story.

Loupe basics

Loupes (French for “magnifying glass”) are high-quality magnifiers, originally used to help focus images on a ground glass, and later to view slides or negatives on a light table. You can find them in all shapes and sizes, at prices from $15 for a cheap plastic model, all the way to over $300 for a Zeiss loupe for viewing 6×6 medium format slides. Slides viewed on a light table with a high-quality loupe are a treat for the eyes, because of the high contrast (1000:1) that you cannot get with prints (more like 100:1).

There are two ways you can use a loupe: use a high-power (10x or higher) to check slides or negatives for critical focus), or a medium-power loupe to evaluate an entire frame (usually 5x-6x for 35mm, 3x-3.5x for medium format). Viewing an entire frame is more challenging than just checking for focus in the center, because the loupe must provide excellent optical quality across the entire field of view. There are variable magnification (zoom) loupes available, but their optical quality is far below that of fixed magnification loupes, and they should be avoided for critical examination of slides or negatives.

I have accumulated quite a few loupes over time. The most famous brand in loupes is Schneider-Kreuznach, a German company noted for its enlarger, medium format and large format lenses. Many other brands make high-quality loupes, including Rodenstock, Pentax, Nikon, Canon, NPC, Leica and Zeiss. I do not live in New York, and have thus not had the opportunity to compare them side by side at a place like B&H Photo, so I pretty much had to take a leap of faith based on recommendations on the Internet at sites like Photo.net.

• Peak 10x Plalupe
• Contax Carl Zeiss Triotar T* 5x (larger photo)
• Edmund Optics 50x direct view measuring microscope
• Calumet-branded Rodenstock 3x Aspherical loupe for 6×6
• Calumet-branded Rodenstock 4x Aspherical loupe for 35mm
• Edmund Optics 10x Hastings Triplet
• Schneider 10x magnifier

Peak

The Peak was my first loupe. Dirt cheap, and reasonably good for the price, but that’s pretty much all it has going for it (more on that below).

Zeiss

I was put off by reports on the plastic construction of the new line of Schneider loupes, and opted for a Zeiss loupe instead, based on the reputation of Zeiss lenses (my first camera was a Zeiss, and I also have a Zeiss lens on my Hasselblad).

The Zeiss Triotar 5x loupe (the box does not mention Contax, but as it is made in Japan, it is presumably made in the same factory) comes in a cardboard box that can be turned into a protective case by cutting off the tabs on both ends. It does not include a carrying pouch or protective box, which is regrettable, specially for a product as expensive ($160), but apparently most high-end loupe manufacturers do not bother to include one. It does not include a neck strap either, which could be more of an issue for some. How can you look like a glamorous New York art director without a loupe around your neck? More seriously, the strap is particularly useful if you are going to use the loupe for focusing medium or large format cameras against a ground screen.

The loupe is shipped with two acrylic bases that screw into the loupe’s base. One is frosted, and is used as a magnifier to view prints or other objects, with ambient light filtering through the base to illuminate the object. The black base is used to shield out extraneous light when concentrating on a slide or negative on a light table or a ground glass. Some loupes have a design with a clear base and a removable metal light shield. Which design you prefer is mostly a matter of personal taste. The loupe has a pleasant heft to it, and impeccable build quality. The main body of the loupe itself is solidly built of black anodized metal, with a knurled rubber focusing ring.

The optical quality is what you would expect form Zeiss. Crystal clear, sharp across the field of view, and no trace of chromatic aberration in the corners. You can easily view an entire 35mm frame and then some, although I suspect eyeglass wearers might find the eye relief a little bit short.

Edmunds pocket microscope

The Edmunds direct view microscope is a versatile instrument, available in many magnifications, with or without an acrylic base (highly recommended) and with or without a measurement reticle (metric or imperial). Due to the high magnification, the image has a very narrow field of view (only 3mm), and is quite dim. Unlike the others, the image is reversed, which requires some adaptation time. The level of detail you can observe on slides taken with a good film like Fuji Provia 100F, using a good lens and a tripod, is absolutely stunning. This is a rather specialized instrument, but well worth having in your toolkit.

Rodenstock

The Rodenstock 3x 6×6 aspheric loupe has a list price of $350 and usually retails for $250. Calumet Photo sells the exact same loupe under their own brand for a mere $149 (I actually got mine for $109 during a promotion), which is not that much more than a cheap (in more ways than price) Russian-made Horizon.

There are naturally fewer loupes available to view medium format slides or negatives than for 35mm. Schneider, Mamiya/Cabin, Contax/Zeiss and Rodenstock make high-grade loupes for this demanding market. If you have a “chimney” viewfinder on your MF camera, you can actually use that as a loupe.

Rodenstock is famous for its large-format and enlarging lenses, and this loupe is very highly rated. The construction is plastic, but still well-balanced and not too top-heavy. It does not carry the feel of opulence that the Zeiss has, or even the very nicely designed Mamiya/Cabin loupes (more on that below), but is still clearly a professional instrument. It has a two-element aspherical design for sharpness across the entire field of view, and coated optics. It comes with a red neck cord, and the base has a removable plastic skirt that slides in place and can be reversed between its clear and dark positions. The eyepiece has a rubber eyecup and a knurled rubber grip for the focusing ring.

I compared it side by side at Calumet San Francisco with the Cabin 3.5x loupe for 6×4.5 or 6×6. The Cabin had a solid metal constuction (somewhat top-heavy), but its screw-in skirts are less convenient than the slide-in one used in the Rodenstock, and the image circle is too tight for my Hasselblad 6×6 slides. I think that loupe was really designed for 645 format and opportunistically marketed for 6×6, when the 6×7 loupe would actually be more appropriate for that usage. The optical quality is very similar and both are excellent loupes. I did not try the Mamiya/Cabin 6×7, unfortunately, as it was not available in the store, but in any case the Rodenstock was a steal.

The optics are excellent, as could be expected, with crisp resolution all the way into the corners and no trace of chromatic aberrations. There is a smidgen of pincushion distortion, however, but not enough to be objectionable (I took the slightly convex curved square skirt out to make sure this was not just an optical illusion).

One thing to watch out for: even though the optics are coated, they are very wide and you have to be careful to keep your eye flush with the eyecup to obscure any overhead light sources like lightbulbs or fluorescent panels and avoid seeing their reflections in the loupe’s glass.

The most comprehensive resource for medium format loupes on the Web is Robert Monaghan’s page on the subject.

Edmunds Hastings triplet

This isn’t really a competitor to the other loupes, as it has a very narrow field of view of only 10mm in diameter. It is also tiny, and I carry mine in my gadget bag. It has a folding jeweler’s loupe design with a folding metallic shield to protect it. Optical quality is of the highest order.

Schneider 10x

Despite its plastic construction, this loupe exudes quality. Unfortunately, the strap is really flimsy – the rubber cord is merely glued into the metal clip, and will easily pull out. I glued mine back, and crimped it with needle-nose pliers for good measure, but I don’t know how robust this arrangement will be.

The optics are excellent, without any trace of chromatic aberration. The usable field of view is surprisingly wide for a loupe with this magnifying power, although your eye has to be perfectly positioned to see it. I estimate the FOV diameter at 20mm, as you can almost see the full height of a 35mm mounted slide. I have an Edmund Optics magnifier resolution chart (it came with the Hastings triplet), and the Schneider outresolves it across the field of view . This means the Schneider exceeds 114 line pairs per millimeter across the frame, quite remarkable performance.

The importance of a good loupe

For a real-world test, I took my 6×17 format Velvia 100F slides of the Golden Gate Bridge, and looked at the suspension cables. The picture to the left shows the details I was looking at (but the fuzzy 1200dpi scan on an Epson 3170 does not remotely do justice to the original). Each bundle of 4 cables (4 line pairs) takes 0.04mm on the slide (I used the 50x Edmunds inspection microscope to measure this), hence you need 100lp/mm to resolve it. The Schneider 10x, Edmunds 10x and Zeiss 5x loupes all resolve the four cables clearly. My old el cheapo Peak 10x loupe did not, nor the Epson scanner, which led me until recently to believe my slides were slightly blurry because I had forgotten my cable release that day. So much for the theory you do not need an expensive 10x loupe to assess critical focus because only the center counts…

Update (2012-02-10):

In 2007 I added a Calumet-branded 4x Rodenstock aspheric loupe to my collection. Unfortunately, it is now only available under the original brand, for 2.5x the price I paid for the rebranded one, but you may luck out and find old-new stock at you local Calumet Photo store. The market for loupes has mostly evaporated, along with the popularity of film, and choices today are pretty much limited to Schneider and Rodenstock.

The Rodenstock 4x loupe has one great ergonomic feature: instead of interchangeable clear and dark screw-in skirts, it has a clear skirt and a sliding dark outer skirt. This allows you to switch very quickly from inspecting prints to slides, without the laborious swap the Schneider or Zeiss force you into. Optically it is excellent, sharp across the field and with only a smidgen of pincushion distortion. I have not tried the 4x Schneider loupe, which gets rave reviews, and cannot comment on whether the ergonomic improvement in the Rodenstock warrants a 50% premium in street price over the Schneider.

One loupe I cannot recommend, on the other hand, is the Leica 4x magnifier. It has severe distortion across the field, which is ridiculously limited at 3 or 4mm, and optical quality is worse than a cheapo plastic loupe from Peak.

Update (2012-02-25):

I added a Schneider 4x loupe to my collection. Build quality and strap is similar to their 10x loupe. It is sharp across the entire frame, with only a smidgen of pincushion distortion. It is also noticeably brighter than the Zeiss Triotar or the Rodenstock 4x, and has more contrast as well. The contrast makes it seem superficially sharper than the Zeiss or Rodenstock, but examination of the Edmunds test chart shows all three loupes outresolve the chart.

I think this will be my new favorite loupe for 35mm use.
