The kind of sequence that kills a camera: or, advancing waves at 14mm. Olympus E-PM1 Pen Mini, 14-42 kit lens.

Let’s just say there was a reason I was using this and not, say, an M9. Also, I was moving out of the way rather quickly!

I’ve been experimenting with sequences/ sets a bit lately; it’s something that I thought might be interesting to build off the contact sheet idea – any not make the contact sheet and thinking process part of the desired end output? But then I suppose it would require us to think about the individual frames in the context of their own contact sheet, which would be rather meta and confusing…or perhaps the right way to approach this would be thinking of the sequence in itself, much like a video clip – except we just capture key frames. I have a sneaky feeling that pursuing this path of development will eventually lead me back into experimenting with cinematography again (which will be the subject of a future article).

A quick reminder: My Singapore reader meet up will happen tonight, at 7pm, outside Ion Orchard near the red floor installation and the ‘bubble’ MRT entrance. You’ll find me because of the M9-P hanging around my neck, and I’ll be wearing a red t-shirt. (For some odd inexplicable reason, this is beginning to feel like a blind internet date. Oh well, at least we know we all have one thing in common!) We’ll wander around from there and find something to eat. Looking forward to meeting you all! MT

Zone focusing and shooting hyperfocal

Hyperfocal shooting is a subset of zone focusing. Both are very, very useful tools in the arsenal of a photojournalist or street photographer; especially so if you’re using a manual focus lens, or one with a meaningful depth of field scale engraved on it. It means that if you know what distance your subject has to be at to fill your frame correctly, you can set that and just shoot straight away when you bring the camera to your eye – a very fast way of working. It’s what I usually do when I have enough light and a wide lens on my Leica.

Let’s start with zone focusing. It’s simple if your lens has a depth of field scale:
1. Pick an aperture
2. Find the depth of field scale markings corresponding to that aperture.
They’re on the bit of the lens that doesn’t rotate.
3. There are two of them. Everything between those two marks will be inn acceptable focus. Why the hesitation around ‘acceptable’? Because sharp-at-the-100%-pixel-level defines acceptable focus, and that will vary from camera to camera – the higher your pixel density, the narrower the acceptable focus margin will be. You’ll have to experiment for your camera and find out how much (if anything) to compensate by – for some cameras, you might find you have to as much as halve the width of the gap between the two markings.

Example: in the image below, the lens is focused just after 1.5m. This means the sharpest point will be at 1.5m, but if we set f2.8, objects from 1.2m to a bit over 2m will be in focus. Selecting f5.6 expands this further to 1m to 5m.

A good rule of thumb is 1/3-2/3: one third of your DOF will be in front of the focus distance, and 2/3rds behind.

Simple, right? There are a few more things to know.
1. It works best for wide-angle lenses, because they have more DOF for a given aperture. (You could zone focus with a telephoto, but you’d need a silly small aperture and probably run out of light).
2. It works best during daytime, because you’ll have enough light to stop down a bit (and thus increase your margin for error).
3. It works best if you have some practice estimating distances, because you can adjust on the fly without having to bring the camera to your eye.
4. It works best with smaller sensor cameras, because again there’s more DOF for a given angle of view (focal length equivalent) and aperture – for instance, the Ricoh GR-Digital III has a ‘snap’ mode that sets focus to certain distance; at f2.8 and 1.5m, almost everything will be in focus from 0.75cm onwards or so.
5. You can’t do it easily with modern AF lenses – those which do have DOF scales usually only give f11 and f22, which are heavily restricted by the amount of light you’ve got to work with; then the distance scale itself is short and probably not very precise, with few distances marked; lastly, there isn’t enough precision in the focusing ring. You could do it by using the AF system to focus on a distance, switch to MF, and set your aperture – but you’d have to memorize your DOF tables, which is never easy or fun.
6. Some compacts are better than others for this than others; the best kind have manual focus with a DOF indicator bar and scale – the Leica X1 and Ricoh GR-Digital series come to mind.

Let’s move on to hyper focal. The hyper focal distance is the setting beyond which everything is in focus to infinity at a given aperture. Even super-shallow DOF lenses like the Noctilux 0.95 have a hyper focal distance – but it’s probably 50m or something at f0.95. Once again, the wider the lens, the nearer the hyper focal distance will be for a given aperture. With lenses in the 28mm range, you can work at a reasonable aperture of f8 or so and have hyper focal distance at about 3m on a full frame sensor, which is great for capturing spontaneous moments in photojournalism or street photography.

There are several very useful calculators online, such as DOF Master – playing around with this will give you a good idea of which of your camera/ lens combinations is best suited to zone focusing. I personally do it with my Leica M9-P, and sometimes with the Ricoh GR-Digital; but never with the DSLRs because AF is very nearly as fast, especially on the D700. Also, beware lenses like the Olympus ZD 12/2 for micro four thirds – it might look like it has distance and DOF scales, but the focusing ring is electronically coupled, and lacks the resolution to make it truly useful.

I love and hate the idea of skeleton watches. Seeing your wrist hair through the dial isn’t so fun; but being able to see the movement definitely is. This shot is a play on the transparency of the watch – you know it’s there, but at the same time, it isn’t. MT

Singapore Reader Meetup: Wednesday 25 April, 7pm.

Like the title says: two days from now, Wednesday, 25 April, 7pm – let’s meet outside the entrance of Ion Orchard and figure out where to go from there – near the red floor installation and the ‘bubble’. Please leave a comment if you’re coming. See you all there! MT

Photoessay: City Hall, London

City Hall, London – headquarters of The Greater London Authority and home to the Mayor’s office. An interesting blob of a building located in Southwark, near the southern end of Tower Bridge, it was designed by Norman Foster and opened in 2002. It sits at the center of an open plaza with a recessed area containing F&B outlets and entrances to the surrounding buildings, as well as a museum. I just like the architecture. MT

Workflow

I get two questions regularly:

1. “What camera should I buy, or should I buy X or Y?”
2. “I have the same equipment as you. How do you make your images look the way they do? Why can’t I do it?”

I’m not going to address the first question here. As for the second question, there are two answers and one fundamental underlying question: assuming the problem isn’t with your composition, what is it about your workflow that creates that very visible difference in the final image?

Workflow is very important to professionals, because if you’ve got a very high image throughput, then you can take on more work, deliver better quality images to your clients, and at the end of the day, make more money. So it’s in our interests to be as efficient as possible, without sacrificing quality. Good workflow should have the absolute minimum number of steps, be fast and easy to execute, automated to the greatest extent possible (but recognizing that individual images are like children: you have to treat each one differently) and most importantly, be camera independent. The latter requirement is so that you are free to use the best tool for the job without worrying about what to do with the files later. There’s no getting around the fact that different cameras and lenses require different amounts of editing or correction to achieve the desired results; it’s just something that has to be built into your process.

A common misconception is that workflow just covers the post-shoot editing process: it doesn’t. Workflow affects the entire way you execute an assignment, from preparation to final image delivery. What follows is a high level overview of the way I work, and some of the key steps.

1. Prep
– Make a list of equipment you’re going to need.
– Charge batteries, and bring 2x the number you think you’ll need – s*** happens.
– Ensure you have spares: cards, batteries, flashes, bodies, RF calibration spanners…
– Unless you’re shooting a run-and-gun stealth photojournalist assignment, or are going to be carrying your equipment for long periods of time, take everything you think you might need. Better to have it and not use it rather than miss a shot for want of a lens.
– Pack with plenty of time to spare, in case you find you’re missing something or can’t decide which configuration to use – at least you’ve got time to think it over or go out and buy anything critical that’s missing.

2. Shoot
– Turn up early so you can set up (if required) and be relaxed. Nervousness means jumpy hands which means blurred images.
– I always shoot RAW, for maximum latitude later when processing.
– Write-protect your keepers in camera to prevent accidental deletion.
– Shoot bursts where possible, both to get duplicates (insurance) and a choice of material to work with later.

3. First edit
– Delete the ‘obvious fail’ shots in camera when you have downtime – but ONLY when you have downtime. Missing a shot because you were staring at the back of your camera is an amateur’s mistake. I’ll probably dump about 50% of the images at this point.

4. Post-shoot
– Unpack
– Clean equipment – lenses, filters, eyepieces, LCDs etc.
– Recharge any depleted batteries
– Put everything back where it came from, so you can find it again next time.

5. Dump cards
– I will dump all cards to my primary processing machine at this point, and leave the cards unformatted back in the camera – just in case a file gets corrupted or I need the original, I know it’s still there.

6. Backup
– I use a Mac. At this point, I’ll run a time machine backup on my primary processing machine.

7. Second edit
– Delete the images that don’t really work at larger sizes – see my previous article here on editing. I use Adobe Bridge to delete and rate images. Another 50% of the images will go.

8. RAW conversion
– Depending on your machine, figure out how many RAW files you can open before it starts to slow down (use the ‘efficiency’ display in Photoshop; it’s in the bottom left of your image window. 100% means that everything is being loaded to RAM, which is the fastest way of editing). I can open about 15 12MP files in 16 bit before things start to slow down. This means I’ll probably load 20-30, because I also delete some at this point.
– Load bunch of files (20-30) into Camera Raw.
– Make primary exposure adjustments; I will adjust white balance, exposure, shadow/ highlight recovery sliders, vignetting.
– I only crop to aspect ratios that are non-native for my camera. If I’m using a multi-aspect ratio camera like the Leica D-Lux 5, I won’t crop at all.
– I have created a color profile for each camera I use so that I can get consistent color and the same look out of any camera I use, this is applied to the raw file in ACR.
– And same for the tonal response curve.
– Open the files in Photoshop (I’m using CS5.5 Extended now) at maximum quality: 16bit, full resolution.
– B&W conversion: depending on what final look I want, there are many options: gradient map, desaturate, channel mixer…to be the subject of a future article.
– Make curve adjustments – sometimes up to four or five times.
– Any retouching is done at this point – e.g. dust removal for product shots, or color enhancement using brushes and masks. I use a Wacom Intuos4 6×9″ tablet for this, nothing else so far gives me enough fine control.
– Local dodge and burn where applicable.
– Finally, sharpening: do this last, so you don’t land up increasing image noise/ grain. Must be done after curves.
– Convert to 8 bit and desired color space.
– Save final file. I generally use a maximum quality JPEG unless the client demands otherwise; you really can’t tell the difference unless you’re going to do future manipulation on it. (Revisiting old files will be the subject of another future article).
– Optional: do an incremental backup again, if it’s a big conversion job you can’t finish at one sitting, or if each file is time consuming and will take a lot of effort to duplicate.

9. Final edit
– Go through the set again. Keep only the unique, essential images. By the time I’m done, I keep only 1-5% of the initial shoot volume.

10. Portfolio selection
– I keep a portfolio of images for the subjects I commonly shoot; this gets updated after every shoot, especially if I feel there are images that should be added. It’s my aim to have at least one image to add to the portfolio (and replace an old one) from each assignment; this way, I force myself to continually improve.

11. Backup and format
– Dual duplicate sets of images with all raw files to external hard drives, one of which is kept offsite
– Keep finished files only on main processing machine
– Final backup: time machine of main processing machine
– Only now will I format cards. Where possible, I keep at least two copies of the original files – just in case something goes wrong. It’s happened to me in the past, and I’ve been very, very grateful that I did remember to backup. I’ve been doing it religiously ever since, and highly recommend you do the same.

A note on filing: I store images in hierarchal folders by Subject>Event/date>Subset. This allows me to find things easily. I have a separate folder for work on assignment, which is named with something sensible and a date. I don’t like database-based programs for image management like Aperture, because it’s very difficult and unwieldy to manage if you have a lot of images.

12. Delivery
– Send off the images to clients; either over the web, or via DVD.

Now, repeat! MT

POTD: Urban isolation

Shared space, but no shared connection. Leica M9-P and Zeiss ZM 2/50 Planar.

Five people effectively occupy the same 1.5 square meters of space, yet there’s absolutely no interaction between them. The two outside probably don’t even notice the third person inside hovering over them drinking soup; for all we know, they could even be texting each other. If he was at the same table without the glass barrier, the outside couple would probably feel quite uncomfortable. People everywhere but each retreats into their own worlds. Is this a metaphor for modern society? Perhaps. MT

Photoessay: Catwalk fashion with a Leica M

Here’s an unusual challenge. During my ‘early Leica era’, I decided to challenge myself: I shot a catwalk fashion assignment with a Leica M8 and 35/2 ASPH, rather than my usual D3/300mm combination. How did it turn out? Different – and that was the point. The client magazine was pleased, which is what mattered. And boy, it was possibly the most difficult shoot I’d done up to that point – this being early 2009 – because of the combined challenges of extreme lighting, new and unfamiliar equipment, manual focus, and a much shorter focal length than usual. The plus side is that nobody seemed to mind too much when I was roaming in and amongst the guests; an M8 is surprisingly at home in this environment. One nasty surprise was the IR pollution issue – at this point, my UVIR filters hadn’t yet arrived, and I spent a LOT of time afterwards correcting the color. Even so, you’ll notice a higher than normal proportion of black and white images in this set. MT
