Hiya Puddin'! Miss me?

2 Firsts.

This was my first and second exposures ever made of a) pinhole photography and b) color photo processing.

#1 http://www.deviantart.com/deviation/48313028/
#2 http://www.deviantart.com/deviation/48291691/

The first is a smaller aperture (larger image); the second is a different aperture, slightly bigger (you can see the edges where the light ends). These exposures were made with my *SUPER HIGH END* Kenneth Cole Shoebox and color negative photo paper. I was testing to see a) the area of exposure b) whether or not the hole was adequately "focused." Future exposures will be on 4x5 negative & color film and more 8x10 photo paper; possibly, 8x10 negative film. Ten 8x10 negatives go for 70-80$ whereas 100 sheets of photo paper is 40$ so that all depends on how much money I have to throw around (which isn't much).

Attached are campics of the front and back end of my *SUPER HIGH END* camera lens. Roughly f237, but seeing as I do not have a nanoruler, I cannot give a precise measurement.

So when are you going to post some images from your Kenneth Cole? I love pin hole cameras. Mine were alway the Orange Juice can variety.

i had oatmeal pin holes! fun. im rather jealous you have color processing capabilities wherever you are. no fair. but look fabulous!

Stunning.

I built a PHC as a young physics student, but never had the option of making colour pictures with it.

I did use the pinhole effect to enable me to see once when I broke a set of spectacles, many moons ago.

that is really cool. Such a simple camera design with very good results. How do you figure exposure time?

I used the sunny 16 rule ;P
B&W paper is about 10 ISO, so I guessed that color paper would also be in that area ISO. In sunny conditions, a good exposure would be 1/10th of a second @ f16. However, the proposed ideal f-stop for the dimensions of my shoebox are f237, which is roughly 8 stops from f16.

1/10th -> 5 -> 2 -> 1" -> 2" -> 4" -> 8" -> 16" -> 32"

On a sunny day, at f237 and ISO 10, the ideal exposure is roughly half a minute. But it was a cloudy day and a bit dark, so for the hallway I increased another 3 stops (32" -> 1' -> 2' -> 4') plus reciprocity failure just in case (4'+2'). And for the stairwell, I decreased another 1.5 stops because there was less outdoor light, so that was about 15 minutes.

I used this website to calculate the ideally focused pinhole size for my camera here --> http://www.mrpinhole.com/calcpinh.php
Note: some of the calculate fields aren't linked and won't update themselves, so you have to enter data from the right to the left. It's kind of confusing at first, but it was easier than calculating it myself.

I recently exposed some negatives (not paper) and actually attempted to measure via light meter, but my dial doesn't go to f237 so I had to guess the equivalents again. At least it was a lot less math on my part. o_O

DEVIANTART!!! Wow, I was pretty sure none of you guys were on there. That's cool.

Pinhole cameras are fun, good job so far. I'd love to see some more

Aww, I never got to make a pinhole camera for my photo classes I like the perspective you've taken of that hallway, can't wait to see more!
