Pinhole Perturbations

Journal Entry: Wed Jul 1, 2015, 9:05 AM
My very good friend feigenfrucht :iconfeigenfrucht: has recently been turning her considerable photographic talents to the subject of pinhole photography - see some examples below.

There is a small but active Group Pinhole-Camera devoted to the technique - well worth a visit. Further, there have been some previous Features on the subject on DeviantArt, such as:


Pinhole PhotographyIt is a bittersweet feeling to be talking about this because this is how I first started the world of photography 4 years ago this past August. I arrived at photo class in my sophomore year in high school and the first lesson was pinhole cameras. To my surprise I could make my own camera and develop the prints in the darkroom with out even using a real camera, but one made out of an oatmeal container.
Basic Parts and Functions of a Pinhole Camera
1. Body- light tight bow which holds the light-sensitive photo paper
2. Lens (pinhole)- focuses rays of light from the subject to produce an image onto the photo paper
3. Aperture- the size of the lens opening
---->small- less light enters (long exposure time & sharper image)
---->large- more light enters (shorter exposure time & fuzzy image)
4. Shutter- device that controls when the light enters the lens
5. Focal length- the distance between the lens and the focal plane
---->longer- telescope effect (subject appears larger in
   Through The Lens #6 ~ The Pinhole PhotographDating all the way back to the time of Aristotle there is record of devices that used light to cast an accurate depiction of the devices surroundings on a screen, wall, or plate. These devices are referred to as the camera obscura. They have taken many forms and variations but most of them consist of a dark box with a tiny hole on one side. This would allow light into the box which would then create an image on the opposite wall of the box revealing whatever the hole was pointed at. This device helped early artists, especially the Dutch masters of the 17th century, to produce accurate drawings and paintings with perfect perspective. Some art historians believe that it was not a sharp spike in "artistic ability" that took art to the next level but rather the use of these devices. This idea is still controversial but painter David Hockney and physicist Charles M. Falco have advanced the discussion. There is a wonderful documentary by David Hockney called Secret Knowledge that demons


Here are a few examples of work from Pinhole-Camera

Technique

Without going into detail, there being an abundance of information on the Web about the topic, pinhole photography does not use a conventional lens, but one with a tiny aperture (eg 0.25 mm), the pinhole, that allows light into the sensors. There is no control over the lens, and exposure has to be set, initially at least, by trial and error. The images are normally very soft with low to medium contrast, and variable saturation. There is a considerable dedicated following for this type of photography.


My Efforts

Having been prompted (some might say pushed! :laughing:) by feigenfrucht, I thought I should have another go myself. I use a Holga lens that just slots onto the Canon body. Because exposure times can be substantial - 1 - 10 seconds perhaps, a tripod is normally essential.

I have also been investigating the NIK software package available now from Google that runs via Photoshop Lightroom, and that contains some amazing editing filters. One of these is in the Color Efex Pro 4 suite, and is called the Bleach Bypass filter. First developed about 50 years ago mainly for use in movies, the filter gives rise to a sort of high key black and white image overlaid with a flattened colour image. Google and ye shall find all sorts of info on Bleach Bypass. Anyway, I thought I'd try this filter with my pinhole shots - hence here are some Pinhole Perturbations.

The first image is an anomaly in that the "diamond ring effect" comes from light scattering off the inside of the lens's casing before entering through the pinhole. Careful alignment of the lens with respect to the light source, the Sun in this case, results in the effect with larger or smaller "rings" coming from different angles.

The second image illustrates a second feature of pinhole photography - close-up photography is not a problem, although expect to see some spots and specks in the images as the effective aperture is so tiny that dust/dirt on the sensors will show. The three subsequent images are all "landscapes" where the bleach bypass filter starts to show its potential. Colours are washed out, and the "feel" of the images is like that of old hand-painted photographs. Detail is lost, but block shapes such as the cloud in the last image show their form. Note also that I have left the circular, almost black, vignette in place, this coming from the casing of the lens.

Whether these images pass muster in the pinhole photography world is for others to assess, but they are an attempt to explore what many find a fascinating photographic field.

   Pinhole Camera made out of 150-year-old skullIf you're going to make a pinhole camera for taking pictures with, there are probably more practical cases for it than a 150-year-old human skull. But then again, it's tough to find a more unique camera than the Third Eye, which is indeed made out of an old skull.
It's a sculpture, technically, so it's not like you'll be seeing skull cameras popping up at Best Buy anytime soon, but it is a functioning camera. The skull formerly belonged to a 13-year-old girl, who now has a camera placed on her forehead. I'm sure the photo quality isn't all that great, but hey, you'll always be sure to capture some freaked out expressions on your subjects faces. And that's gotta count for something.

Worldwide Pinhole Day ! Join in the Wonder of Pinholes!
"No photographer is as good as the simplest camera".  ~Edward Steichen
The most amazing thing about pinhole cameras is they can be made from virtually anything, as long as it can be made completely light-tight. A shoebox, a Pringles tube, a film cannister, a matchbox even! It's mostly trial and error, but that's the joy of photography :) The process should be more fun or at least as much as the result. If you don't already know about the incredible and original methods of capturing and painting with light, where every container can be a camera, check out the links below, and HAVE FUN! You don't need a top of the range 5D amd all the filters and lenses to create incredible images, you don't even need a lens!

  World Pinhole DayToday (April 25, 2010) is World Pinhole Day!
World Pinhole Day is a day to celebrate the simplicity of a pinhole camera.  A pinhole camera is a camera with no lens... just a single small aperture.  Light passes through the tiny hole creating an image.  Since the aperture is so small with a pinhole camera, it requires a very long shutter speed.  
Pinhole cameras are easy to make!  Or you can turn an SLR (or digital SLR) camera into a pinhole camera by drilling a small hole into a camera bodycap.  
For more information on Wold Pinhole Day and pinhole photography, check out pinholeday.org http://www.pinholeday.org

   Whats in the bag? 009rdungan1918
This week I have something different for you, rdungan1918 is a fellow caffenol user and alternative process photographer. Here he shares whats in his pinhole camera kit bag.  

The contents of my pinhole bag. The bag bought at Goodwill for $3.49, note pad and pen, roll of film in film container, a AirBorne Container (just the right size to hold a roll of 120 film, a 120 film spool with black electrical tape and gaffers tape for emergencies, a imini tripod (I usually carry a bigger tripod), extra roll of Arista.edu film, 1970's light meter, Holga 120 Stereo Pinhole in back ground and the papers in front are exposure guides for different pinhole cameras. One thing not shown in the picture is a cable release I was using in on the Holga 120 WPC taking the image. 
Exposure 9 min & 48 sec, I also took several flash pictures of the setup with my Cannon S95 and Olymp
   2015-033 AlchemyPinhole cameras are more alchemy than science.
I went prowling on-line today for pinhole exposure calculators, having had a series of badly under and overexposed shots. By rights one ought to be able to compute the f-stop by dividing the effective focal length--the distance from the pinhole to the film--by the diameter of the pinhole and work from there. Unfortunately, the relationships are not linear as exposure times get past a second or two and one has to throw in a "reciprocity-failure" multiplier for longer exposures. Fudge factors rule!
I printed the charts and tucked them into my little book, which will now have to do double duty as journal and exposure record. It will henceforth be the alchemist's journal.
I found a reciprocity fudge factor chart at http://www.instructables.com/id/Design-and-Build-your-own-Pinhole-Camera/step9/Loading-and-Shooting/

Best of June 2015

Welcome to the Best of June 2015 Feature from Infrared-Club

This is going to be the last such Feature for some time. I've run out of steam, and I need a break. There will be some organisational changes, notably that there is now an Open Folder for both  IR and Exposure Technique work with ALL members, regardless of status, limited to 5 submissions per week. 

I draw your attention to my previous post ==>  Development of the GroupI've been thinking for some time about the future of :iconinfrared-club: We have come quite some way since I took over more than 3 years ago. Nearly 700 members, a few thousand submissions, about 120 (!) Journals/Features, some fruitful discussions, many experimental and reference submissions and so on. Mostly, the Group runs smoothly with the semi-open policy that I instituted; submissions from regular members have a 1 vote acceptance of submissions - more to do with category errors than quality issues; those members who submit quality work on a regular basis are invited to become Expert Members with a 10 submission auto acceptance limit. To broaden the nature of the Extra-Visible aspect of the Group I introduced the Exposure Technique category for mainly HDR and long exposure work.  People come and go but we have many continuing members, some of whose work is outstanding by any photographic criteria. Help is given mainly to the compilation of the "Best of..." monthly feature.
Ye
. Any further comments would be most welcome.

ArtWorldToday is a Group for anyone who enjoys art. You don't have to make it to be a member. Art comes in all forms and what is art to one person might not be art to another. So you must be kind to other members. We will have beginners as well as established artists in this group, so there is a variety to look at.


My husband and I used to live in a town that had a active Art Walk. We enjoyed going on the First Friday of every month. There were so many talented artists in the town we lived in, and this was a way for people to notice them. We have since moved and the town we live in now doesn't have a Art Walk that show cases artists the way our old town did. I miss the environment of the Art Walk, I miss the getting to know the artists and I miss seeing all the new artwork.

I thought fine I will make my own First Friday Art Walk here on the web. I hope that we will build a fun group with lots of networking, interaction and support amongst artists of different types and abilities.

Not everyone can go to an Art Walk but here on the internet we can have our own form of Art Walk. On the First Friday of every month we will feature new artists for the month!
