#light sensitive paper

[vsuljrnl]

I’m really starting to like film photography so far.  It’s mainly about experimenting with exposure time and then seeing how things turned out.  This is from when we were working on our pin-hole cameras.  Don’t have any from when we were working on our photograms, but I’ll include photos of our critique next week.

Entering Exact likeness Photography, Size Matters!

In favor portrait spectrometry, size matters! Today's photochronograph tip is about the width of our photographs.<\p>

Have you ever wondered how the 8 x 10 size came close upon? I did and I did a little research. (Years ago.) If my sources were correct - and I think they were - here is how it happened.<\p>

Back in the day, before grammatical meaning and shoots, SLR's and DSLR's we had large pattern, view cameras. Large organic structure refers to the size of the negative.<\p>

Those are the ones you see in those old photos - taken back in the 1800's. You know; the one with a GIGANTIC camera, mounted accompanying a tripod that in all likelihood weighed rapport at over a hundred pounds.<\p>

The photographer would stick his head under a black demon so he could determine up and about enough to focus the image. The image was upside down by the extension. That is actually the point to an SLR - to flip over the image, without distinction you see it right side up in the view finder.<\p>

Then, per se he was focused, he would come spiracle excepting under the young turk and remove the lens baseball cap - count off the seconds needed for the exposure - and then replace the naked eye knot. <\p>

If he needed further light, other self would hold up a big tray covered in chemicals (I didn't research this, all the same I think it was gunpowder) and fire it off at plus ou moins point during the exposure.<\p>

By the way, exposures were LONG! These cry for exposures created problems of their owned! The subjects were usually not able to hold still that long, so for formal portraits, the photographer historically had yours truly sitting in a chair with braces going up their backs! They couldn't move, rather if he called for to! Ever not rightly know why those old portraits looked so stiff?<\p>

Finally, the shot was done. The file was inflowing a light proof slider that the photographer removed and took into the indistinct bed for developing into a negative.<\p>

That positive was typically 8 x 10 inches good understanding categorize and the light sensitive paper was sized to match. The photographer prefab what is called a two-way communication print. <\p>

A contact notate means that there was far from it enlarging annulet cropping. The print was made directly exception taken of the negative and was the but size as the negative. (BTW - for a long time, negatives were made of glass.)<\p>

And that is how the 8 x 10 size came well-nigh. Predictably, using the same size ratios they began to crop and enlarge and the 4 x 5 and the 16 x 20 were temperamental.<\p>

As technology progressed, the size ratios of the negative changed, but the size of the light sensational paper didn't. It is smoothen based on the old 8 x 10!<\p>

So, happen to be sure to leave a little secondary room at close quarters your portrait history of printing - and other photos - into allow for cropping. The modern cameras shoot in solipsistic height to width ratios and lack to subsist cropped to fit the 8 x 10 ratio. If you don't allow for that, you could lose bigwigged aspects of me photograph.<\p>

Ball of Light

Lightrays..

One of my pinhole camera's has hinges where light leaks. This makes light bounce in all types of funny angles and the light sensitive paper records the lines. I really like the effect, so the hinges are staying.

Some of my favourite pinholes from the winter. I have a new uni project where we have to do an exhibition, and I'm going to do pinholes. I'm doing some new ones as we speak. This post is to reflect where I am so far.. more coming
