Pinhole Camera Experiments

I have the good fortune to be able to access several pinhole cameras. 1 5x4 inch one and an 8 x 10 inch one. Last night I brought home, the 8 x 10 inch one.

I then loaded it with paper and went outside. I have no idea what the aperture of the camera is so my idea was 2 fold.
Try to determine the aperture
Work out a way to make teaching the use of the camera; easy and approachable.

I teach a subject called Experimental Processes and Theory I am adding this to the list of experimental ideas students can approach.

My first exposures were 16 seconds and 30 seconds, I then developed the paper negative in Dektol for 3 minutes. The neg had tons of density in the sky, but shadow detail was lacking somewhat in both negatives, so I decided to increase exposure, next going for 1 minute and 2 minutes, again developing in Dektol. Again plenty of highlight density and some gain in the shadow but not enough for a reasonable print. It seemed that the highlights were blocking up too quickly. This got me thinking can I shorten the developer time or soften the developer?

I tried shorter times first, and exposing now for 2 and 4 minutes respectively. with only one minute in the developer. Straight away I saw some improvement.

There are numerous ways to extend development time to lower contrast in photographed scenes. I decide to use a highly diluted film developer called Rodinal. This meant I could keep my Dektol at 1 + 1 for future use. I diluted it to, 1+100, and started with a 5 minute development time. Bingo, now tones were looking much more manageable, even with 4 minute exposure times in late afternoon, late autumn light.

Here are final the results, one scan is unaltered, the other simply inverted using Potatoeshop.

Eventually I plan one making a direct contact print from the original negative. Come back in a day or two, to see if I succeed?

[Total time 4 hours]

March and tons of PD already!

March has almost ended and I have undertaken a heap of PD already.
Firstly there's the dreary bureaucratic stuff! One hour. It was kind of pathetic, the principal lead the session and left the most difficult part till the end, and rushed it leaving more confused people than ever. I was all over it, because it was a simple web based form. More on this later.
Then there was the new paper I tested for the students, 6 hours in EP&T.
Lastly, I made some books to and used the art book fair to try and sell them. 200 hours. I made 2 books. One a simple single sheet zine, which went through two revisions and ended up being constructed of two weights of paper as I created a cover for the final version. The other was a perfect bound book, of about 48 images and printed by blurb. Sadly this arrive late so it didn't get to me in time for the Art Book Fair at the National Gallery of Victoria. All up though it was a fantastic learning experience.

What a day!

Well what a day. Saw some great art, and had a very relaxing day all round. Took comprehensive notes, and will copy and paste once we get home. Made a few pictures, but, all in all just soaked up the art. it was fun and some team building did occur. It would be great to do something similar at some point, in the not too distant future, let's hope the others feel the same!

2016 in Reflection?

It would appear I have not kept such good records this year of my Proffesional Development? I have been using my VIT page more I feel. Anyways, I have done a couple of PD online sessions as well as attending a VDC training day.One online training session for DEAT, OH&S, [2 hours]Two days of a TAE40110 Certificate IV in Training and Assessment in house at NCAT [12 hours]One day of trainging on mental health awareness, Science of Mental Health, by Dr. Maria Roberto, looking at how menalt health develops and developing strategies for helping young people cope. [6 hours]As for creative work I have had work in 2 group shows, both in South Australia. These kept me quite busy this year. [120 hours]

Also the annual 1/2 day VTAC training and I guess that covers me for 2016. [4 hours]Not sure of actual hours though?
