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!

52 Rolls Week #14

52 Rolls Week #14 includes many of the SFX-200 Experiments.


Trying for some silky water effects.

SFX-200 Panorama Experiment

Panorama Photomerge of the Indian Peaks and Longs Peak:


And the constituent parts below:



I could decrease the contrast a bit to brighten the images.  But I wanted to show them 'as is'.

Ilford SFX-200 Experiments

I've been continuing to experiment with Ilford SFX-200 film in preparation for Moab Photo Symposium:


I'm using the IR 695 filter with the SFX-200.  Of course Everything that is green is very dark.......


Our Blue Jeep definitely absorbs the IR Spectrum.


And Donald with the Burke and James Press Camera doing his own 4X5 IR experiments.

A few more from the Horizon Perfekt


I Really liked the way this view of the Flat Irons turned out.


Just a view of the Prairie at the Rocky Mountain Arsenal


And a Panorama at my friend's Church, St Ambrose.  Opens up some interesting opportunities for Architectural Photos.  Hadn't thought of using a Panorama Camera inside.

Panorama Comparison #1 & 52 Rolls Week #13

I'm going to be posting side-by-side comparisons for several options that I have for shooting Panoramas.  You've seen some of these cameras before and others will be new options for familiar camera friends.

Today a new Option.  I will be doing another series, because I had different films in these cameras and I want to do a true direct comparison with the same films and exposures, etc.

But we will start with a new option for an Old Friend:  The Mamiya 7 with a 35 mm Panorama insert and the Horizon Perfekt swing lens Panorama camera.  I had forgotten that I had color film in the Horizon.  But the main thing to notice in the comparison is that the horizon has a much wider field of view,  and that was what I wanted to learn from this experiment.


Above (Mamiya 7 35mm) and Below (Horizon).  Reservoir at the Rocky Mountain Arsenal.




Second view of the reservoir, panning north from the same position.





The Indian Peaks from Lake Waneka.


I assume that the streaking is an artifact of developing.  What do you think?



And the NOAA Satellite Communication Dishes.



Some interesting results. As I said we'll do a Redo for a more direct comparison.  I've posted the B&W images as Week #13 of the 52 Rolls Project.  I will post the color photos for Week #14.

Hops and Handrails Part Deux

So the Handrails idea is to bring snow down from the mountains and have snow boarders and skiers do stunts.  But our unseasonably warm weather played havoc with idea.  Nevertheless, they persisted:



But the I think the Harley's win for best ride:

Saturdays Online: I Would Never Waste Good Beer......

Or even a cheap beer trying to develop film.  But in the mind numbing search for new ways to develop film that DON'T reliably work as well as traditional methods....Now you can develop your B&W Film with Beer.  Check it out if you are interested. I guess we would call this an experimental method.  At least Caffenol only uses horrible instant coffee that you should never drink anyway.

Let's move on to Something that makes sense, Like Free Beer For A Year! No Foolin'


We won a free growler every month from the Sponsors of Hops & Handrails, 

And  few B&W views from Hops and Handrails:


Nice to see participation from the Midwest.




As a geochemist by training, I really liked the Periodic Themed Beer. 
We'll have to check them out next time we are in Leadville.


This has been posted as Week 11 of the 52 Rolls Project.

Next we'll see what the 'handrails' are all about.
