Pinhole Photography and Solargraphy

[StarryEyes]

I'm curious, has anyone ever tried to photograph star trails or long night shots with a pinhole camera?

Also is there anyone out there who has tried Solargraphy

The whole idea of a pinhole camera is the very small aperture so it is very unlikely that it would be sensitive enough to record any stars.

It's like using a DSLR with a lens at something like f128 or f256 or smaller. To record a subject normally takes a lot of minutes/hours so a long night shot would work with a static foreground being resolved but there would be no sky details other than light pollution.

This is a reasonable example from flickr and I think the 'stars' are probably artifacts as they doesn't exhibit that much trailing considering it was an 8 hour exposure.

Thanks Kev, that image it quite interesting, shows no stars just the moon. I suppose Reciprocity Law Failure could be a factor as well.

I understand how a pinhole camera works just never tried to do that with it, wondered if it was worth giving it a go. Probably not (unless the moon is out and there is an interesting foreground lit) going on the image.

Something I played a long time ago. Maybe I'll try my hand at it with a 5d mkii some day

This is a great activity to try out, I am going to set up one ready for the winter solstice.  I will attempt a 6 month exposure to start with I think.
