One of the most iconic images of the 20th Century has to bee Dorothea Lange’s image, Migrant Mother…

Lange-MigrantMother02

She took this as part of her work for the US Farm Security Administration – who were tasked amongst other things of documenting the effects of the great depression on the poor – a task generally considered as a platform to provide political support for the social reform of the rural poor in America in the 1930’s.

Believe it or not a vast number of images of this era from the FSA have been digitised but like all things a large collection of 170,000 images is nothing without some way of finding your way around. At Yale University they have created Photogrammar which for the meta-nerd in us does a spectacular job of bringing a decade of photographic  history to us in a wonderfully time-spacial way. Enjoy.

The Unobtainable

The limits of photography are always being move forward. In the days of film these advances were very small – today digital technology moves forwards faster and this can be seen in the story below.

Late one evening our hound wandered up the backyard and by chance my eye was drawn to a bird flying to a rest in a tree nearby – illuminated from the indirect light of a flood lamp 20 meters away. Around here a bird flying at night can only be an owl and with a quick trip inside I grabbed the first torch I could see – a cheap LED unit – and went back out. There it was perched in a tree – surely it would be gone by the time I’d gone back in and got a camera and lens…

So armed with a 5Dmk3 and a 400mm f2.8 IS I had the best chance technology could just about give me…

ISO:           25000
Aperture:  f/2.8
Shutter:     1/6 sec
Lighting:   cheap LED torch

…and to add a bit more of a degree of difficulty didn’t have time for a tripod or any other support…

Now I can’t say technology is perfect since the image below shows the difficulty the camera and I had in focussing in such low light – about 20 missed shots. But the one at the end is something that 30 years ago would have been utterly unobtainable.

Packing List

 

James,
All the best for your trip to Europe. I hope you enjoy all the 6 or so months you have there. You asked for my packing list so here are my thoughts. They may not be the best of thoughts but a useful collection of things to keep in mind.

I’d start with the basics….

  • your 5D (I think yours is the mk2)
  • a good collection of CF cards – each one labelled with e-mail and numbered so as not to cause confusion
  • 24-105 f/4 or 24-70 f/2.8
  • a fixed big aperture lens – 50 f/1.4 would be good – for shooting at night, in galleries and isolating parts of a scene.
  • if you have something wide then take it as well something like the 17-40 can be good
  • a small telephoto (you are not going to use it much but it can come in handy when walking the streets of a city
That’s 4 lenses above. Carrying all would be a chore but after a week or so you’ll have an idea what 2 you are going to pack into your bag for any particular day.
Accessories:
  • A small discrete camera bag. For security something you can put at waist level rather than on your back. Think of something that will take your body and two lenses (one fitted). It can also be used to carry souvenirs and other nick knacks.
  • A polariser for getting those deep blue Grecian Skies.
  • An ND400 filter to have some fun.
  • A cable release (the ND 400 will need to be used with one).
  • A “bag” for support – perhaps find a small zippered cloth bag – I’m thinking a small clothes delicates bag that you can fill with foam packing peanuts when you are over there – you can use a Velcro strap to attach it to your camera bag strap when walking around – total weight a few grams.
  • Steal a hotel shower cap – it makes a good impromptu rain cover.
  • A spare battery.
  • Your battery charger – don’t forget to pack it when you are moving between hotels.
“Maintenance” things:
  • Rocket blower stored inside a clean plastic bag.
  • A small microfibre cloth.
  • Something to transfer photos to and cloud storage to keep them safe.

Other tips

  • Leave the battery grip at home.
  • If your camera bag gets wet let it dry thoroughly over a heater – any foam in it will retain moisture.
  • If something happens you have a credit card and places to shop.
I think that’s about it. Have fun and I look forward to seeing the results.

Autumnal

There is some biological versus climate thing in the hills that delays the onset of the winter for just a few weeks more than places down in the city. This gives the photographer a quick last chance to spend a few hours roaming the places near home, with camera in hand, to observe the passing of the season.

At some point the last leaf will fall and winter will arrive but it won’t be a time for hibernation just a time to refresh and think of other different things. I look forward to that time.

The South of France

I think it would be a common assumption, that as you go towards the equator, the weather will get a little more comfortable in a French February.  The more accurate observation is that the Pyrenees range and its high peaks with villages and snow capped mountains will surprise.

Get Closer

Some things in this world can be done in strangely different ways – macro work is one such thing. There are various ways to get more subject magnification with macro photography these include:- different lenses, extension tubes and macro filters.

A macro filter is a simple convex lens that, like spectacles for those with long vision, allows you to move the lens closer to the subject. The problem is that these types of screw on lenses tend to be of a simple design which keeps cost low but provides less than optimal image quality. What we really need is a good quality macro filter with coated optics and kick ass quality – this is where the unnatural stuff happens.

Some years ago someone realised that a second camera lens could do a great job of getting that extra magnification. The easiest way to mount the lenses to each other is to reverse the second lens and use an adaptor to go front to front or stacked (not to be confused with the macro technique of focus stacking) as it’s known.

The adaptor rings fit the filter threads on each lens usually of lenses of similar size. In the shot below you can see a 50mm f/1.4 attached via the adaptor ring onto the front of the 100mm f/2.8 macro.

IMG_0126-L

The trick is finding an adaptor ring here in Australia – perhaps they exist but they are rare as hens’ teeth. Some people use two cheap filters and remove the glass and then glue them together. This works but I somehow wouldn’t trust glue to keep a delicate 50mm lens from falling off. I found using two Cokin P-series adaptor rings you can make a flexible adaptor ring.

IMG_0127-XL

As can be seen the adaptors are joined back to with three small screws drilled in the metal towards the edge. If I decide to use a different lens then all I do is unscrew the halves and fit the appropriately sized adaptor ring. The cost of the generic adaptors used were around $8 each – approx $20 for some serious macro fun – bargain!

The adaptor rings fit the filter threads on each lens usually of lenses of similar size. In the shot below you can see a 50mm f/1.4 attached via the adaptor ring onto the front of the 100mm f/2.8 macro.

To give you an idea of what you can get, the two images below show a 100mm macro alone at maximum magnification (on a Canon 5D both shot at f/11) and using the stacked 50 f/1.4 at maximum magnification. As can bee seen from the first image above the focus distance is very close – this results in half of the battery below being in shadow. As you see at f/11 depth of field is razor thin.

_MG_9967-XL

The shorter the focal length of the front lens the greater the magnification and the closer you have to put your object of choice. A 28mm for example approximately doubles magnification over using a 50mm. Some combinations of lenses may vignette – especially on a full frame body. Given the huge magnification it’s a method best used indoors on a tripod.

Un-natural stuff like stacking lenses isn’t for everyone but for about $20 it could be worth giving it a go just for the fun of doing something new and different.

Train Coming

I’ve seen a lot of images taken with a ND400 (10 stop neutral density) filter, I’ve taken several with my own. A common theme amongst them is slowing water and other natural movement in landscapes. As a different aspect for this filter, I decided to take an iconic photograph of the Puffing Billy steam train that runs near home.

Getting closer…..

Getting Closer

The challenges are several fold in shooting this scene – trains run every 90 mins or so in this direction, deciding the shutter speed, focus and exposure on a moving target that will only appear for a few fleeting seconds are decidedly tricky.

Just past….

In the end it’s not a perfect image. The front of the train is just past the apex of the bend – a point where the motion of the front of the train would have been frozen. The other little gripe is it was just a bit too nice of a day next to the bridge – the normally wet weather gives a deep colour to the forest and a darkness to the wooden bridge.

It’s a promising use of an ND400 filter so I’ll be back at some stage in the future when I hope I’ll be able to catch the train.

The times they are…

..changin’

One of the small damnations in digital photography is that when you travel you sometimes forget to adjust the time on your digital camera when you travel. Thankfully Lightroom has a solution in hand to keep the image libraries organised.

In the Library module select all the images you want to adjust. Go to the metadata menu > choose edit capture time

time_ajust_1

from here you get the adjust capture time dialog box

time_adjust_2

I used the shift by a set number of hours option. The head hurts bit is finding out the correct number of hours to adjust by. In this case it wasn’t too bad since Europe is GMT and I could add an hour for daylight savings time to get me to -11.

After this is done you can then filter your library to confirm that you can tell sunset from sunrise in Paris.

time_adjust_3

One of the small issues remaining, as the name implies, is that only the metedata of the file is changed – file operations are not performed so you have to move the files to the correct dated folder yourself.

The Band

There is a band – its name is Shanty Town.

It’s the kind of band that plays the perfect accompaniment to dancing, a little bit of drinking and having a very good time.

1O6A6048

Matt contacted me and asked if I’d be interested in getting some promotional images of the band together before one of their performances. I think for a second… I think about a great location for a second… and jump at the chance.

1O6A5956

The location was a laneway out of the back of the club that they were playing that night. It was a little bit of a challenge shooting such a large group in the dark with the occasional car passing through. One or two shots were sacrificed to the occasional blinking eye.

Afterwards a drink of a nice pear cider allowed me the chance to sit down toward the edge of the stage and shoot a few more.

Find Shanty Town on the web here – but I do urge you to find them in reality, wherever they are playing, and have a very good time.

A Few Days in Paris

I had the opportunity to travel – I always consider travel a very fortunate opportunity – to Europe. The first place on the itinerary was Paris. In a way, such a heavily filmed and broadcast city was always going to give me an element of ummm…  deja vu without even having experienced it before.

Perhaps the things best discovered and best photographed are the familiar sights from new perspectives. When you have the chance to physically move around then you discover new little things – the viewpoints which are part of an immersive experience that the two dimensional world can’t convey.

 

The Eiffel Tower in the early light of dawn. Once called a glorified lamp post by a critique – and it had several of them – these days I suspect every night time lamp on the Tower, in a way, represents one of those critiques.

The Lamp Post

 

It’s only when you’re inside the structure that you realise how the Tower is a marvel of hollowness. Everything you take for granted as being solid is, in fact, thin cast iron plates and angles that have a standard size.

The Skeleton

The month of February isn’t what you’d call the best time to visit Paris if you are looking for sunny weather. Fortunately there is ample space inside the entrance of the Lourve from which the stormy skies can be observed from a perfectly climate controlled environment.

There is one advantage to jet lag and wet weather – it does allow you to get up fresh as a daisy at 5 in the morning and walk to the very quiet river and parts of the city with camera and tripod.

There were three weeks in this trip and Paris was the first three days of them. I won’t spam you with posts about Europe, Europe, Europe all the time but keep tuned as I make my way through the image collection.
