Macro photography with reverse rings (poor guys macro) explained

Yay!
I got my first macro shots with a reverse ring! :D

I was really surprised how fast I managed to get a clear shot!
It was very challenging working in Manual mode.

But in one evening experimenting with my camera, I already learned a lot.

So, here is a "how-to" for working with macro reverse rings!

1. You need the right lens. You need a manual lens with an aperture ring.What also comes in handy is an Automatic-Manual switch. Why do we need that? The lens is reversed so that switch doesn't function anymore, right? No! (See 5. )

2. Mount the reverse ring on your camera first. And demount it. Just to make sure it fits right. Now mount it again, and than screw the lens on.

3. Turn your camera on. Set the camera on M mode. Set the lens on the biggest aperture it has! (The smallest number) Now, you can look through the viewfinder and try to guess the settings you need and make a composition.

4. The problem with macro is that you don't want a too shallow DOF, Depth of field. This is the area wich is in focus. And I tell you, this is very small with a reversed ring. It's probably 1cm to 5mm. To make the DOF bigger, you'll need a smaller aperture. Ok then, lets make a smaller aperture.
Ow....Our viewfinder turns black, and our picture turns out too dark...
Yes...
So this is why you will either work with a longer shutter speed or with flash. The longer shutter speed is not a good option since we are working MACRO!! Every slight movement will make a blurry picture. And the advantage of a flash is too freeze the image. So turn on that flash!!
I did my pictures for now with the simple pop-up.
I'll soon make a flash extender and diffuser so that the flash will actually point at the subject and wont be that harsh anymore.

5.Ok, our flash is on. But we still can't see anything through the viewfinder! This is where the pin on the backside of your lens comes in handy! Turn the lenses aperture wide open. When you have a A-M switch, turn it to A. Now you can turn the aperture to about f8 or f11 depending on the situation. Push the pin, and....MAGIC! the aperture stops down!

6. We are going to take the picture! Settings ok (ISO,Shutter speed, white balance...)? Aperture wide open? Then immediately push the pin so the aperture stops down, and take the picture!
If you don't have the A-M switch I think you'll have to turn the aperture ring quickly to a higher f stop without moving your camera and take the picture.

I hope this helps!!

Here are the first pictures I took with this method:

Happy Newtonmass!!

And off course a merry merry christmas to everyone!

To all non nerdfighters and science lovers: 25th december is the birthday of the great Isaac Newton. (Actually 4th of January in the old calendar back than)

We really have to think a little moment at him.This great mind invented modern calculus, Newtons laws of motion and much more fundamentals for todays physics and mathematics.

What I will do on christmas eve, today, is go outside, look up at the stars, and thank him. Thank you, Newton. Thank you for opening the door to understand our universe much better.

Here a little carol for you, Newton!

God rest ye merry, physicists
Let nothing you dismay.
Remember Isaac Newton
was born on Christmas Day!
His gravity and calculus and “f” equals “m” “a”!
Oh, pillars of physics and math, physics and math,
Oh, pillars of physics and math!


A factor of big G – the same for flea and giant star.
Then multiply the masses and divide by square of “r”.
The force that keeps us on the earth and orbits moons afar!
Oh, pillars of physics and math, physics and math,
Oh, pillars of physics and math!

Now, calculus is math for those
who change things bit by bit.
To figure out derivatives
and get the curve to fit.
Then integrate and you can find the area under it!
Oh, pillars of physics and math, physics and math,
Oh, pillars of physics and math!


For those of you wanting to send a "Happy Newtonmass" card: Here is a card I made using photoshop;) You can use it!

Illustrating experiment!

The last few weeks, I've been experimenting with making some illustrations.

I really didn't know how to begin. So I just bought a great Staedler 0.1 water resistant pigment liner.
Good buy.

So I drew the outlines and then coloured in with watercolours.

Still not good I think.

There has to be some other way to do this.

Here one of my experiments:

I don't know if some of you know the story of Medusa?

Medusa was first a beautiful girl, just like her other sisters (together they were called 'the gorgones').  But Athena got angry at her and transformed her into an ugly snake-headed women who could stone people. For the reason of her anger are several story's. One is that she slept with Zeus...

I like to use Greek mythology in artworks.

But I have to say, this wasn't really a piece of art in which I'm showing my skills! Everyone could do this:) You just need to have the idea!

No lazy sunday

Today I showed my -eagerness- haha

I visited a company working in nanoelectronics and nanobiotechnology.
I may be still an undergrad, but I think you can never start too young with networking.

I already got some information to do a PhD or an internship there, pretty great huh?

And when I got home and checked my mail, I saw that I have a job! Yeah!
I'll be working some hours in the week in a lab: making samples, cleaning glass, weighing samples...

What did we learn today?
Never too young for networking.

And sience is awesome, off course...

Chapter 3: Eager

Eager to learn...

I don't know why, but I just like to know things.

I'm a kind of person thats interested in everything. I like to learn new things. And that could be in theoretical way, or practical, as an experience.

Like travelling: I hate persons who take a plane, travel to a beautifull country, and don't even leave their hotel. Really, I HATE them.
If I travel, I'm not a tourist. I'm a traveller. I'm interested in their culture, history and nature. I visit their country, to learn something.

Uomo Universale. Like a walking Wikipedia, haha
Yes, that's what I want to be.
Sience, history, art, culture....
And I want it just for myself. Not to show people how smart I am, or I don't know what.
No. I want it, because I appreciate life. I don't know how to explain it. What is life worth, if you don't know anything about life?
I think everybody has his own answer on the question: Why do we live?

I could answer it paradoxical: I live to learn and experience, and I learn by living and I gather experiences by learning from life.

Ok, maybe that's nonsense.
I just don't know how to explain it. It feels that I have an inner voice wich tells me to learn :)

Linux

I'm digitally cursed! Haha
I have the same laptop since 4 years, and every 4 months I needed to reinstall f**kin Vista. My laptop crashes everytime with those stupid updates.
So I decided to install linux ubuntu.
And it was great! No stupid adds, updates or viruses!
But of course my laptop even crashes with linux.

If I was a computer geek I would  invent my own operating system!
