Exposure time calculation

I got some enquiries from buyers lately about how to calculate the exposure timing for the different pinhole sizes on the camera.

To help all of you out there, I have created a table and a turnwheel for your easy reference & usage.

How do you use & read it?

1. First you take a meter reading for the subject that you are going to shoot.
2. With the metering, read off the appropriate f stop timing horizontally along the table. For the turn wheel, align the f stop & shutter speed by collapsing both wheel on top of each other, then read off the f stop reading accordingly.
3. For 0.2mm pinhole aperture, read off the timing for the equivalent under the f128 column for the exposure timing. For 0.3mm pinhole aperture, read off the f90 pinhole column for the exposure timing.

Please note that the table has been created for metering done at film speed of ISO100 with reciprocity failure taken into considerations in the timing. So, you can use the recommended timing for exposure that you read off from the table directly.

I will use an example to illustrate:

If the metering reading you have taken shows at ISO100, to be f8, 1/125seconds. Read off the equivalent horizontally will give a recommended exposure timing of 1 second at f90 (0.3mm pinhole size) & 2 seconds for (0.2mm pinhole size).

Showcase of Alois Lazecky’s works

I received more impressive images from users of the 8banners pinhole cameras worldwide. They have used their tools to create highly impressive images & visualisation.

Here’s one of the artiste from Canada, Alois Lazecky who bought a 6×18 Dragon 2 camera a month ago have been shooting happily on the new toy. Here are some of his works & a short bios about himself:

BIO:

I have been enjoying photography ever since I was about 15 years old beginning in my old country Czech republic. Shortly after my family and I have decided to find better place for living and moved to Canada where I’m still to this day. I have used pretty well most of film formats from 35 mm to 8×10″ and now digital. As nice as digital equipment is, I still like to use film cameras and better yet and what I’m having fun with is your Dragon2r pinhole camera. Most of my photographs are landscapes, city panoramas and still life.

Installing the Turret Assembly

I got many enquiries about how the turret assembly is to be installed on their 8banners pinhole cameras. So, I piece together some instructions in images for easy reference for all who have problem understanding the notes I send you all via email. I think in such case, it’s always “A picture paints a thousand words!”
