Nature and animals are my passion in photography. In 2010 I bought a DSLR, some lenses and tought myself the basics of photography. After buying a true 1:1 macro-lens I find myself more and more enthusiastic about the wonderful world of macrophotography. The natural world is my favourite subject, however, I never hesitate to try and make a nice picture of anything interesting that comes along. Finally, I look for something more in my pictures, in means of something has to 'happen' in the photograph. The picture has to have a story of some kind and preferably a story that I find worth telling. It's something I always keep in mind when going out with my camera, it keeps me keen, alert and critical.

Home-made orangejuice flashtube?

Hello everyone,

In her comment on my picture 'Let's Dance' our fellow 500px member Jane Sleeth posted that she had no idea what my home-made orangejuice flashtube was. This is not the first time I got that question so here we go:

First of all, the 'problem' or rather 'challange' with my macro's is, in my opinion, the available light. Typical I want a small aperture of f/11 and above, even better is f/16. Together with that small aperture I want a low ISO rating to get the most out of my pictures. With my macro lens, a 90mm, I need at least a shutter speed of 1/125 to avoid shaken images, eventhough I have set my 'SR' on in my K-x body.

So summed up that's:

- f/16

- iso100

- 1/125

Do the maths, I need a lot of light!

The typical insect macro-lens is, imho, at least 90mm and has a aperture of f/2.8. That means a long lens, and that means that if I use my built-in flash, the light of the flash does not reach the object that's in front of my lens. So it's pretty useless...

I need to ...
