Solargraph from Frederiksberg Have. Exposed december 30 - march 7.

The dark stripes indicate longer periods without sun in the first months of the year.

Another Solargraph image from a pinhole camera made out of a baked bean tin, this camera was left out on the moors above Greenbooth Reservoir for 11 weeks.

This modified camera had a smaller pinhole (0.372 mm) than the previous version (see post from 27th December) and the smaller pinhole has definitely optimised image sharpness. It (along with the little stone placed on top of the camera) succeeded in Ietting in less rain so this image isn't water damaged like the last one was.

Now that the camera needs no more modifications it's time to leave a few out for 6 months, from the spring to autumn equinox to record the strong summer sun trails.

Water Damaged Solargraph

Another Solargraph image from a pinhole camera made out of a baked bean tin, this camera was left out on the moors above Greenbooth Reservoir for 10 weeks.

I already knew (after calculating the ideal pin hole size for the bean can after the last attempt) that this image would be blurred like the one I collected after 5 weeks, but unfortunately due to the recent storms it was also water damaged as water had worked its way into the can.

The new modified camera that replaces this one has a smaller pinhole of 0.372 mm which should optimise sharpness.... And hopefully Iet in less rain.

3rd Attempt At Sun Trails With A Homemade Pinhole Camera

1st Image - final inverted digital scan
2nd image - the black & white photographic paper

This camera was a pinhole camera made out of a baked bean tin, the previous ones were made out of thinner coke cans. The camera was left out on the moors above Greenbooth Reservoir for 5 weeks.

Quite happy with the sun trails but the image is not as sharp as the previous ones from the coke can cameras, it appears this is due to the pin hole being larger on the bean cans (it was drilled rather than using a pin). After calculating the ideal size for the bean can (see equations) it appears the hole needs to be reduced from 0.5 mm to 0.372 mm to optimise sharpness.
