It's Worldwide Pinhole Day!

Here again, and I hope you are out Shooting!  Take a look at past Pinhole Day Postings.


And  Flash from the Past, circa 2013:

My Gear for Pinhole Day

I finally took pictures of the Zero Image Pinhole:

Pinhole Time Testing with Portra 160: Part II

Back with the Zero Image Pinhole, and a time test without a sky view.  As we say in the previous post, a sky view will wash out if you use the longest exposure.  Bu here, without the sky, there is almost no perceptible difference in the results at a very wide range of exposures.


Exposed 5 Seconds:

Exposed 10 Seconds:

Exposed 15 Seconds:

Exposed 30 Seconds:

Of course, I will mostly be shooting landscape images with a sky view, so I'll be exposing at 5 & 10 seconds for Pinhole Day.

Pinhole Time Testing with Portra 160: Part I

I'm getting ready for Worldwide Pinhole Day by performing real time tests.  When I shoot B&W I just guess at exposures and bracket.  This time I wanted to try Color Film and decided to go into the field prepared to expose the film properly.

I also wanted to use the Zero Image Pinhole instead of my usual Holga Pinhole. I hadn't shot much with that camera the Zero Image, so here we go.


I looked up the Portra 160 Reciprocity Curves, but even at f/235, I found that I didn't need as much exposure as the curves predicted.

Exposed 5 Seconds:

Exposed 10 Seconds:

15-30 seconds was recommended by the curves, but with a bright sun just out of view, 5-10 seconds worked better.  notice below how the blue sky in the upper right washes out as exposure increases.

Exposed 15 Seconds:

Exposed 30 Seconds:

However, with the sky not in the view, the exposure time differences are not noticeable at all.  We'll look at that in my next posting.

Denver March For Science: I Marched, Did You?

Today someone at the March for Science asked to photograph my camera.  He said he aspired to move from digital to to medium format film!

More from the March For Science once my Film is developed!
