Camera Obscura

The camera obscura is about 200 years old. The name comes from the Latin words for ‘dark’ (obscura) and ‘room’ (camera). With a camera obscura, you can perfectly capture the world around you by projecting what’s on the outside down into a darkened space on the inside you don’t even need a power source. it’s not magic it is just some really useful science. ​

it is a rather theatrical-looking curtain that surrounds the darkened chamber, there’s a large lens mounted in a wooden panel. That lens focuses the light from the scene outside down onto a mirror which is held at a 45-degree angle behind it on the inside. The mirror reflects the rays of light onto a piece of paper or canvas laid out flat on the base inside the wooden box. To see the image, you need to cover yourself with a piece of black cloth to stop any other surrounding light from getting into the box. You’d then trace the outlines of the scene you can see projected onto the paper inside. And because this camera obscura uses a lens, which creates a relatively large aperture, you get a sharp, colourful image on the paper like a mini video feed of the outside world. ​

Because the light is bouncing off the mirror, you see the image the right way up. But the lens causes the image to flip (or invert) so it’s also the wrong way round. That meant artists using a camera obscura would have to trace the final image in reverse. There is plenty of evidence that masters like Canaletto and Rembrandt used the camera obscura, but other artists may have been more secretive. People still debate whether the Dutch painter Johannes Vermeer used a camera obscura to capture the incredible detail in his exquisite paintings of domestic scenes. Although there’s no written evidence to prove it art historians think that he probably did.

Nicephore Niepce​

Joseph Nicéphore Niépce was a French inventor and one of the earliest pioneers of photography. Niépce developed heliography, a technique he used to create the world’s oldest surviving products of a photographic process.

In 1826, Niépce used his heliography process to capture the first photograph, but his pioneering work was soon to be overshadowed by the invention of the daguerreotype.​

Henry Fox Talbot

William Henry Fox Talbot was an English scientist, inventor, and photography pioneer who invented the salted paper and calotype processes, precursors to photographic processes of the later 19th and 20th centuries.

William Henry Fox Talbot was credited as the British inventor of photography. In 1834 he discovered how to make and fix images through the action of light and chemistry on paper. These ‘negatives’ could be used to make multiple prints and this process revolutionised image making.

​Louis Daguerre – The Daguerreotype

Louis-Jacques-Mandé Daguerre was a French artist and photographer, recognized for his invention of the daguerreotype process of photography. He became known as one of the fathers of photography.

The daguerreotype is a direct-positive process, creating a highly detailed image on a sheet of copper plated with a thin coat of silver without the use of a negative. The process required great care. The silver-plated copper plate had first to be cleaned and polished until the surface looked like a mirror.

Richard Maddox

Richard Leach Maddox was an English photographer and physician. Because of him, photography was given an early impetus to become a disseminator of medical knowledge. His interest in the camera, combined with his poor health and his medical training, enabled him to invent the gelatin bromide negative that is the backbone of today’s photographic film.

George Eastman

George Eastman was an American entrepreneur who founded the Eastman Kodak Company and helped to bring the photographic use of roll film into the mainstream. He changed the world through his entrepreneurial spirit, bold leadership, and extraordinary vision.

Kodak Brownie

The Brownie was a series of camera models made by Eastman Kodak and first released in 1900.

It introduced the snapshot to the masses by addressing the cost factor which had meant that amateur photography remained beyond the means of many people; the Pocket Kodak, for example, would cost most families in Britain nearly a whole month’s wages.

The Brownie was a basic cardboard box camera with a simple convex-concave lens that took 2+14-inch square pictures on No. 117 roll film. It was conceived and marketed for sales of Kodak roll films. Because of its simple controls and initial price of US$1 (equivalent to $37 in 2023) along with the low price of Kodak roll film and processing, the Brownie camera surpassed its marketing goal

Digital Photography

Digital photography is a process that uses an electronic device called a digital camera to capture an image. Instead of film, it uses an electronic digital sensor to translate light into electrical signals. In the camera, the signals are stored as tiny bits of data in bitmaps, tiny bits of data that form the image.

ISO

What is ISO and How does it affect your camera?

ISO controls the amount of light your camera lets in, and therefore how dark or light your photos will be. Here are some top tips to help calculate correct exposure: Low values, such as ISO 100, are best for a sunny outdoor shoot. For shooting at night — or indoors with dim lighting — use an ISO of 1600 or higher.

Higher and Lower ISO

Higher ISO numbers increase sensitivity, making images brighter, but also introduce noise or grain. Lower ISO settings result in darker, cleaner images with less grain.

Higher

High ISO is generally well suited to low-light situations, especially when a fast shutter speed or a narrow lens aperture is essential to achieving a creative goal. For example, using a higher ISO setting for hand-held street photography at night allows one to use fast shutter speeds to create bright, sharp images.

Lower

When you are taking pictures in good lighting conditions, you should use low ISO to avoid noise in the image. This will give you the best quality picture. That’s because a high ISO can lead to noise in your photos, which can be especially visible in dark or low-light situations.

My photos using High ISO

I used a high ISO for this photo you can clearly see this as in the photo below I zoomed in and the photo is grainy

Adobe Lightroom

I imported loads of photos into Lightroom (172). I then made a subfolder or collection as its called in the app of all my favourite photos (32) which I then rated out of 5 stars, this app was really useful to help arrange my photos into groups and get them all sorted.

What is Lightroom used for?

Adobe Lightroom is a photo editing and storage application available through the Adobe Creative Cloud. This program allows users to quickly and easily edit their photographs with tools to alter contrast, balance colour, and change brightness on mobile devices immediately after taking the picture.

This is my contact sheet

In the top left I selected the photos I wanted and then pressed print

I then selected this template for my photos to go in

Where its saved

Shutter Speed

Eadweard Muybridge is remembered today for his pioneering photographic studies of motion, which ultimately led to the development of cinema. He was hired to photograph a horse’s movement to prove that a horse’s hooves are clear of the ground at a trot.

The above images are taken with fast shutter speed. Fast shutter speeds of 1/500th are used for capturing rapidly moving objects, such as freezing a race car hitting its top speed. The slower the shutter speed, the more motion blur your camera will capture when shooting fast-moving subjects.

Slow shutter speeds include 1/15 – which is an excellent shutter speed for panning moving subjects. 1/8 – This shutter speed will blur fast-moving objects. 1/4 – Will blur people when walking. 1/2 – You will be able to get slow-moving water with a blur.

Francesca Woodman’s family spent their summers at her parents’ farmhouse in the countryside near Florence in Italy and many of her photographs were taken there. European culture and art had a significant impact on her artistic development. The influence of surrealist art, particularly the photographs of Man Ray and Claude Cahun can be seen in the themes and style of her work. She developed her ideas and skills as a student at Rhode Island School of Design. Her importance as an innovator is significant, particularly in the context of the 1970s when the status of photography was still regarded as less important than painting and sculpture. She led the way for later American artists who used photography to explore themes relating to identity such as Cindy Sherman and Nan Goldin.

Hiroshi Sugimoto is a Japanese photographer and architect. He leads the Tokyo-based architectural firm New Material Research Laboratory. Hiroshi Sugimoto is best known for black and white photographs of particular subjects that he has explored in depth over many years: images of natural-history dioramas, wax-figure installations, sublime seascapes, and ornate movie theatre interiors.

plan for tomorrow: come in grab a camera go outside use slow shutter speed to get a clear shot of a bike then use fast shutter speed to capture a moving bike these two photos demonstrate the differences in shutter speed.

Here are some of my photos and our class photoshoot

We successfully experimented with slow and fast shutter speed to achieve these brilliant photos

Using Aperture

Aperture – Control the amount of blur or sharpness around your subject.

In this image there is a wide Depth of Field giving a smaller lens opening. This means that the area of focus will be wider.

Settings

Shutter speed: 1/3

Aperture: 22

ISO setting: 400

In this image there is a narrow depth of field which will isolate your subject from the background.

Settings

Shutter speed: 1/180

Aperture: 2.8

ISO setting: 400

In this image the depth of field is short or narrow. Notice how the subject is sharper than the background.

Settings

Shutter speed: 1/30

Aperture: 6.7

ISO setting: 400

Focal length is the distance measured in millimetres between the point of convergence of your lens and the sensor or film recording the image.

depth of field is how much of your image is in focus. A wide depth of field would have the whole shot clear in camera however a shallow depth of field would focus in on one point and blur the background.
