A Monk Crossing a Bamboo Bridge Have just returned from a four day visit to Luang Prabang. Four days is hardly long enough to get to know a place and the people that live there - but it was all the time I could spare on this occasion.

The trip began with an eventful arrival. I had less than the required six months left in my Canadian passport and so decided to travel on my UK passport - obtaining a tourist visa from the Laos embassy here in Bangkok. I used my Canadian passport to leave Thailand, and when I tried to enter Laos with my UK passport I was asked to 'have a seat' in a small office and wait while several officers of various rank (over a period of about an hour) came in and explained that I would have to pay a US 200 dollar fine because there was no exit visa in my UK passport to prove that I had come from Thailand. For the most part I pretended to be clueless (not that difficult for me to do), pointing to my Laos visa, and at one point feigned a decision to go back to Bangkok. Smiling a lot probably helped. In the end the fine was reduced from 200 to 100 US dollars paid in Thai Baht. I'd love to know how it was divided up amongst the 'officials' on duty that day.

The rest of the trip went well and we had fun walking around the town, markets and temples. The views across the Mekong and Khan rivers in the early evening were beautiful. Most locals reported fewer tourists than last year due to a large number of cancellations caused by the problems in Thailand - in particular the recent closure of Suwanapoom airport in Bangkok. Perhaps things were a little more relaxed than usual as a result. We made merit at dawn on Friday morning giving rice, chocolate bars and small cartons of milk to the stream of monks leaving the temples to receive alms. I went again on my own on Saturday morning and shared my mat with a Swedish and American couple. I'd read about the concerns by some that the number of photo snapping tourists (including myself) at the early morning ceremony might be changing the nature of the ceremony for the worse, but the atmosphere was relaxed and respectful. It appeared to me that the right balance had been struck between those participating and those wanting to record the event.

Students in the Central Luang Prabang School The highlight of the trip was when we invited ourselves to visit the central Luang Prabang school. We spoke to students and their teacher during a Saturday afternoon class. The school is a combined primary, secondary and vocational college and the students were taking a lesson in nutrition. Most students had travelled by bus from the areas around Luang Prabang to attend class that day. I gave an impromptu (and brief) lesson in Canadian geography, explaining that at the moment the weather is very cold in Canada - reaching minus twenty degrees Celsius during cold snaps, and that there is plenty of snow. I told my usual stories, including how if you breathe in through your nose very quickly, your runny nose will instantly turn to ice (with the usual gasps of surprise followed very quickly by disbelief). And my old favourite - of how during the winter, people that have to park their cars very far from where they work don't always make it to the car before freezing like a statue - and have to be carried back inside to be warmed up before trying again (more gasps and then laughter as I pretend to be frozen). We bought the class a box of cakes, swapped email addresses and said our goodbyes after having rescued them from twenty minutes of nutrition.

I suppose if I have any misgivings about the trip as a whole, it would be the questions I continually asked myself which included: why were people coming to Laos?, and who benefits? One theory at least is that tourist dollars help the local economy and that some of this money will filter down to the average Laos person. Looking at the condition and teaching materials at the local school I struggled to see any immediate evidence of this. What's more - having lived in SE Asia for nearly a decade now, I've seen families that have become rich on tourist dollars - the fortunate ones that have land, or a house in just the right location, and my impression in most cases has been that these families tend not to share their wealth with their less fortunate neighbours. And then of course there is the system of patronage and corruption common in Asia which usually means that by the time tourist dollars have trickled down to the 'average' person, a large percentage has been siphoned off at the top.

The night market in Luang PrabangThe central night market in Luang Prabang is remarkably well organised and suspiciously homogenous in the goods that are on offer. I would have liked to ask the vendors who they bought their crafts from and how much they paid to rent their spot in the market.

I guess the other reason people visit a country like Laos is to experience the culture - to see how other people live and perhaps to learn something about the hardship experienced by those living in a developing country - in particular the minority areas. The trouble I have with this explanation is that Laos is a 'developing' country for some very good reasons. I'm not an expert on the history of the region, but after just a little reading on the topic it's easy to see how the recent and tragic history of Laos (as well as Cambodia and Vietnam) explains a lot in terms of its lack of development. According to the CIA world factbook the average life expectancy in Laos is just 56 years. So does this mean that as tourists, we are benefiting from a tragic past? That we're able to travel back in time to see the 'real Laos' - people in villages living a subsistence existence because of the chess piece wars and conflict in the region that stunted the development of a country which should otherwise have prospered? I'm not sure, and that's probably a simplistic view of the complex combination of conflict, culture, religion and environment that have helped to create and shape the country as it is today.

So would I go back? Yes I would. The people are truly friendly and welcoming. I'd love to spend more time in Laos travelling and talking to people about how they live and the changes occurring in their country.

For now at least I'll have to accept that after such a short trip - I'm barely qualified to comment, and close to justifiably being accused of being a 'flash-packer' in Luang Prabang for four days :-)

camera-front-angled It's taken me about a month to settle on an auto focus strategy for my D700.

I skipped several generations in film and digital SLRs, so getting up-to-speed with the D700 as well as re-learning some of the basics in focus and exposure has taken me a little longer than I'd thought it would.

Thanks to a couple of good forum posts - in particular this one - D700 and autofocus at Photo.net - I now have a much better understanding of how auto focus works in the D700, and in particular the focus points and what to expect in terms of different scenes, lighting and camera orientation.

There's a consensus that the cross type focus points - 15 of them located in the centre of the 51 AF point matrix mean that you may occasionally find it hard to focus vertically (portrait) when using one of the edge focus points. In low light with little contrast and a lack of horizontal lines under the focus point this might be true - and I've been able to reproducibly see the difference in test shots against a target - but in practice - outside and focusing on people at events, or on the street, I'm finding the edge focus points are working ok.

So here's my recipe for fast(ish) focusing - in particular when photographing people at events or outdoors - in either landscape or portrait mode.

1) Remove the focus from the shutter button - (option a5:AF Activation - set to AF-ON button only). I was actually told to do this a while ago by a good friend, Patrick de Noirmont - but like most things - I have to learn them the hard way. :-) There are a couple of good reasons for this. For one, I was losing pictures when I was occasionally slipping, or releasing the focus after recomposing. The D700 is not a light camera (even without the battery pack) especially when there's a 70-200mm/2.8 lens attached to it and so it's possible to lose the 'feeling' of the half-pressed shutter button in all that weight. Moving focus off of the shutter button guarantees that you won't accidentally refocus after recomposing. What's more, you can always pull focus manually and know for sure that pressing the shutter button isn't going to change anything.

2) Leave the focus mode in continuous servo AF mode (the switch on the side). By moving the focus to AF-ON only - you effectively get both single servo and continuous servo focus. Press once for the equivalent of Single-servo mode - press and hold for continuous AF mode. Kills two birds with one stone and no need to flip the switch.

3) This one's important.. turn OFF the image review under the playback menu. Here's why. If you're shooting an active scene (again - an event or people moving around outside) then you're likely going to be moving the focus point using the multi-selector (multi-wheel), focusing, and recomposing repeatedly (especially if you're switching between horizontal and vertical composition). I want this process to be as fast and as fluid as possible. The bad news is that pressing the AF-ON button (or the AE-L/AF-L button) won't interrupt the image review like the shutter button does (turning off the monitor). If you have your eye to the view finder - having just taken a picture, and then try to move your focus point by pressing the multi-selector (before focusing again or recomposing) - you'll actually be moving through images in playback mode on the rear screen. If you don't turn off image review - then you'll have to press the shutter button first - and while that might not sound like a big deal, it's an extra button to push and when you want to move a focus point, refocus and shoot in under a second - it gets in the way.

And that's it... :-)

The results below - after a quick switch from portrait to horizontal - placing a focus point on the eyes (yes - the eyes) with no recomposing.
