- It is Friday...again
- It is wet ...again...
- Have a hot air balloon flight scheduled for my wife's birthday tomorrow morning....it will be cancelled....again (been trying for two years for this flight)
- I do not feel like working....again
so, thought I would just write something to share which should not cause any heart ache or grief....
Last night at Camera Club we had a very interesting speaker (Derek Reay) and his subject was Camera Obscura and Pinhole Photography. Camera Obscura I had never heard of and Pinhole Photography we experimented with at school.
We were shown both black and white and colour pinhole photographs which were absolutely amazing, sharp and crystal clear.
The pinhole camera was made from a wooden box and uses 5x4 film. If he needs to change the dof he just adds another wooden ring and holds them together with two rubber bands, the shutter is a cover over the pinhole and to prevent shake he has rigged up a release mechanism.
Some of the images he showed were taken by a pinhole camera set up in a room which he had turned into a camera (Camera Obscura).
He clears a wall opposite a window which is overlooking a view, blackens out the windows and in the window opposite the blank wall he makes a small hole in the window covering, he then sets up his pinhole camera in the room to photograph the image which appears on the wall. These cameras have an incredible ultra ultra wide angle so the whole room appears on the pinhole image.
Now this is the amazing bit..... wait for it..... the f stop is equivalent to f1400... yep one thousand four hundred and the exposure time... 4 days..... no hurried snap and go shot.... he said his average pinhole shot ranges from two to four hours.
For portrait images he has the pinhole camera about six inches from the "victims" face.....and.....he still gets a background to the portrait !!!!!!
Try that in a town centre !!!!
If you are interested here is the link to his website..... http://www.derekreayphotography.co.uk/index.html and have a look at the Camera Obscura images and the Pinhole Camera images.
After all it is a wet miserable day .
