My idea was to setup and have a month or two worth of sun trails. 24/7 exposure.

A standard pinhole cap allows far too much light in.  The hole would have to be practically microscopic and/or covered with a near-black filter.

Consider something like a time-lapse using a solar filter installed on the camera?

Re: Pinhole long exposures with a DSLR

Yeah, I tried that once in 2018 or so. It's no good with a crop camera.

I hesitate to buy film related equipment, I just don't know the first thing about film. Maybe a 35 mm at some point. Those are still easy to send out to a lab, I think.

I took a look at your three web sites. Very impressive. You need to add WA State to your travel list. We have a lot of great scenery and abandoned places. I tried to get a peek at the Beluga whale that's visiting for the first time in 70 years or so. Not even a glimpse yet, that little stinker is hiding from me. Fun place to live and visit, tho.

Anyhow, thanks for your ideas and your help. Much obliged

Re: Pinhole long exposures with a DSLR

The problem with using a pinhole to photograph the sun, first, the sun will be shining directly on sensor.  Without solar protection, it could ruin the sensor.

The second problem, I suspect the light will glint and glare on the cut edges of the pinhole.

Re: Pinhole long exposures with a DSLR

Yes, I already gave up on my idea. I'll start over with a film camera and go from there.

I don't think that any pinhole that requires exposure times like an f/128 lens or slower is going to have any problem with the sun.

The real problem with such small apertures is that the dark current noise is going to swell very fast compared to the exposure unless the ambient light is very bright.
