My pinhole camera arrived

I still plan to try to make one but I thought buying one (from Flights of Fancy ) would be quicker.
I was only half right as they didn't provide me with a screw to attach the shutter!

I'll need to have a look for a small screw. Once I know I can attach the shutter ok I'll glue everything together (although it's not necessary) and I may even decorate it.

I have 14 little pieces of paper and I plan to use them all in the camera/box. As they will develop as negative prints I can scan them and convert to positive on the computer. I will create proper prints using the negative papers at a later date.

Below is the pinhole camera in progress (bear in mind it is not yet complete).

Lens converted Macro

Whilst taking some photos with my cousins today, I was reminded of a way to produce macro photos without using an actual macro lens. The trick is to turn a 50mm lens back to front and take the photograph this way.

I decided to try turning my own lens back to front (18-200mm zoom) but my camera wouldn't allow me to take photographs without the lens connected (there goes my pinhole idea). So, I borrowed my cousin's 50mm and stuck it in front of my own lens at 18mm - here is what I got (this has not been altered - the circle is how the image was produced).



I then tried it again with my lens at 200mm and found that it was too hard to focus. It seemed that I couldn't get close enough to the subject with this lens and the slightest movement was caught at this focal length - here is the result (this is one of the stamen at the base of the bell-shaped flower).



You can still see the vignetting at 200mm but it's not as bad as with the wide angle. I will try a range of focal lengths and techniques on my next experiment of this type of macro shot.
