I had looked at some of the macro studios that are available in the camera stores. The cheap ones running about 6000円. Not really what I wanted to spend on something I might only rarely use.
After a bit of stumbling around various lighting sites. I found an interesting tutorial on making one of these macro studios at Strobist: DIY Macro studio.
That article says you can make it for about $10 (or less).
I re-used some materials and made mine for free.
Here is the same leaf shot on top of the macro studio at the same angle, without the softening effect of the paper, receiving direct light from the sun.

I did have access to cardboard, tape and my own digital camera.
The first of the card board cameras was made by guess work. I made a light tight box about 12cm high using an old box. The hole in the centre is the lens and the larger square hole is for my cell phone's camera. Rather than taking photographic film and using that, I decided to use another camera to take a picture of the image appearing on the inside of back of the box.
After some research, I found the formula to calculate the size of the hole for the lens.
Got a bigger box and created Cardboard Cam 2.
The small hole in the centre is the lens just like the first camera. However, now it is about half a millimeter in diameter. The larger hole is for the lens of my DSLR camera. The other tabs of paper with holes are additional pinhole lens for the CC2.
A pinhole camera has an extremely small aperature, letting in very little light. Experimenting with the length of time resulted in this interesting series of pictures.
I have left the images unedited and uncropped here. The round, white areas sometimes on the corners are parts of the outside of the cardboard box.
being about 2pm. I think with if I refined the lens a bit more and used even shorter exposure time with increased magnification it might be possible to see details such as sunspots on the sun.
It might be the corona of the sun or blurring caused by the edges of the hole being used for the lens.

I took this shot just before the 2008 Yodogawa Fireworks Festival got underway. It was a 3 second exposure, and was quite overexposed. However, thanks to photoshop I was able to bring the colours back. Shot in .jpg I can't help but wonder how the additional detail in a .raw file would have helped.
I didn't manage to get any shots of the fireworks as this storm rolled over and proceeded to rain for all but 5 minutes of the fireworks show, which nevertheless was quite beautiful.

This is a female Rhinocerous Beetle, it lacks the Rhino-like horn of the males but is almost as large. She was particularly hefty and quite strong. This beetle is about 5cm long.
A large Praying Mantis. Well camoflaged, they wait, wait and wait then when something tasty comes along...BAM! Lunch is served stabbed by and stuck to the forearms, eaten alive to preserve 'freshness'. As is a particularly nasty 'sashimi' dish that I will not partake in, I prefer my fish dead. Raw or cooked, it must be dead.
Sometimes they like to take a walk across the parking lot, and strike a pose for the camera.
Apiphobics may want to skip the next picture.
