YES-YOU CAN Photography tricks and techniques that really work – macro photography using extension tubes

If you are starting with macro photography, you may start looking for the right equipment. Maybe you have a point-and-shoot camera or any other camera with an build in fixed lens, then you probably have an macro mode of the camera.

For cameras with interchangeable lenses, like Nikon, Canon or Sony you can buy very nice macro lenses for $$$ or just an set of extensions tubes for $ (starting at 5-10 $ / EUR in some China shops).

Of course, you will need other things too. An good tripod is important. Maybe some remote shutter release is also nice to have. This article leaves all this out and concentrates on the extension rings.

The floral pictures below were taken form a distance of approx one meter with extension rings and an 200mm telephoto-lens.


 


But – one after the other.

I have purchased a set of extension tubes for Nikon bayonet in China. Delivery took about 10 days. The price was around 8 US $, it passed through customs without problems.

I have ordered the simplest rings / tubes. They are mechanical, they do not transmit focus or aperture information to the camera. You have to set this manually. This is not a problem, you don’t really need auto-focus in macro mode.


 


the tubes have no glass elements.


they have different length – by combining them you get different macro / magnification levels.


 


for this demonstration, I have used the Nikon Nikkor 50mm f/1.8d


this is the set-up without extension tubes


and this the resulting picture


now using different tube combinations


don’t forget – aperture and focus can only be set manually now (check your lens)


 


you will get much closer to the object


getting more details


even closer


getting even more details.

Try different non-macro lenses and ring combinations. Below are some examples of what is possible


 


 


 

Instead of extension tubes, you may also use bellows which give a bit more flexibility but you may need to modify them to adopt to your camera

09MAR2013 Photoresk – Brussels Photography – going to Tournai (the Belgium Burning Man?)

History and Carnival: Photoresk – the Brussels Photography going Tournay

Tournay, the 2nd oldest Town of Belgium (after Tongeren). The picturesque medieval city center. The beautiful market place, the the river Escaut (“Schelde” in Dutch), some UNESCO world heritage sites and –
Carnival? Yes, Carnival!
When nearly everywhere in the rest of the world the carnival season is over, the inner part of Tournai is closed for traffic to celebrate carnival. Probably a good idea to wait ’till spring and definitely something not to miss while in Belgium. Details about the carnival in Tournai can be found here (in french) http://www.carnavaldetournai.be/

There was an parade starting at 14:30 at four different places heading towards the centre. This was be a fantastic opportunity to take great picture of Belgium habits 😉 and the city.

We took the train from Brussels central at noon and returned to Brussels at around 20:00. Trains Brussels – Tournai are ever hour.


Easy by train – Brussels, Turnay every hour, one hour ride

Playing with dimensions

Transformation

A normal picture, photography is two dimensional, right? Usually it shows x and y.
To create (to take) a picture, a digital camera normally has a sensor which has also some x,y dimensions, or resolution in both axes. But not always.
In many industrial and sometimes in surveillance applications, line cameras are used. They have a resolution of, for example x=2048 but y=1 simply one line.
Two dimensional images are produced by moving either the camera or the objects or both. Those line cameras have the advantage of using much less bandwidth while being capable of providing high resolution in one axis.

Taking movies with a normal movie-camera adds another dimension, the time. In the data stream contained in a mp4 file you have x,y and elements of the time, t.
What happens if you play around a bit with those dimensions and exchange y with t to create an two dimensional image? Taking only a ‘slot’ of each individual picture and using the time component for the other axis?
Have a look at the pictures how the time transforms. It is like a hymn to the ‘slow-something’ movement. As faster the objects move as less visible they are….
