History of Photography Assignment

Assignment: History Of Photography Presentation

Students, your new assignment is a research and presentation project focusing on the history of photography and it's role in world history. You will create a slideshow presentation with written notes and give a 5 minute presentation about photography and it's role in history, from technological advances, to social issues and how the camera has become a tool for change in public perception. 

This is an illustration of a camera obscura from the 17th century. Origin: unknown, possibly Italian -  Library of Congress.

In class we will begin with a fun exercise by creating our own camera by hand and create a gallery of images with it (hopefully). The camera obscura (shown above) is an optical device that lead to the development of photography. Light from an external scene passes through a small pinhole and hits a surface reproducing the the scene upside down. The image can be projected onto paper and an image can be traced. Did you know you can visit a giant camera obscura in San Francisco?

This is a photograph of child laborers working in a mine from 1910. Images like these were taken by Lewis Hines for the National Child Labor Committee and helped to change public perception about child labor which assisted in enacting laws to protect children from exploitation, such as the Child Labor Amendment in 1924.

New Assignment: Remake a Classic Work of Art with Photography

Hello Students,

Your next assignment is an exercise in planning, preparation, creativity with location and costume and direction of your model. The idea with this project is to remake a classic work of art using photography and you must demonstrate mastery of light and exposure to create your image in-camera... no post processing is allowed!

 In this photographic recreation of Egon Schiele's "self portrait with physalis" the student created a hand painted backdrop and applied make up to match the original artwork. Photography by Jared Wilson

Remake A Classic Work of Art With Photography:
Now that you have studied all aspects of exposure and how to capture light, you will apply your composition skills, attention to detail and ability to use natural light to recreate a classic work of art. Mastery of exposure control is important, along with creativity and planning and accuracy. You will need to shoot many levels of exposure and try different methods to capture the best light, because there is no post processing allowed in this assignment. In camera manipulation only. You can adjust exposure, color balance and even use in-camera effects if you please, but no lightening or darkening of your exposures in Photoshop, etc. It must be capture "in camera" for maximum points.

• Look through the examples and links below for clarification and inspiration
• Research and find a classic work of art that inspires you. Your final choice of artwork to remake must be approved by your instructor before proceeding
• Keep it classic, think old masters. Im not looking for contemporary artwork, album covers, fashion photography or cinematic references. We want artwork from between 1450 to 1830's and you must be able to identify the artist.
• Final result is a photo only, no color correction, cropping or special effects allowed. If you do it correctly the majority of work happens before you take the picture. For this project post processing is banned. You will need to pay attention to the light in your image and recreate it as best you can. Take many images and adjust exposure, white balance and use in-camera filters or effects to achieve your desired results.
• Put all of your creative energy into the arrangement and recreation of elements. Pay attention to costume, color, light, position, framing, facial expression, body and limp position etc... the key is in the details. Take shots and look at them closely, if something isn't right than re-shoot.
• Elements in your artwork can be re-imagined of course. Strive for recreation of details with whatever you have available and at hand
• Choose and get approval on your artwork of choice before proceeding!

Grading:

This project will be evaluated on your ability to meet the requirements as well as the intention of the assignment. Your work should show careful planning and execution. You are the artist with a vision and it is your responsibility to direct your costume, scene, model and props to achieve your desired results. Having total control over all elements is key to a successful photo shoot.

An example of high performing student work: This is a lovely recreation of Daniel Hernandez Morillo's "woman carrying firewood". The student photographer, Gracie Thomas, took great care with costume, pose, light, props, setting and composition for spectacular results.

This is an example of low performing student work. The student grabbed a bike, a blanket and a model at the last minute and took a snapshot. Little care is put into setting, light, costume, pose, composition.

Principles of Exposure: Capturing and Controlling Value with Studio Lighting

Hello Students,

Having a studio environment and using studio lighting is one of the best way for a photographer to have total control over the lighting and background elements in their photos. Different lighting positions are used to enhance facial features, eyes, hair... and to create different moods, atmosphere and effects in the photo. We will cover some basic lighting set ups and then you will work in groups to create examples of the different lighting positions for portraiture.

When you begin to recognize lighting patterns you can experiment with placement, shadows and light effects.

Studio Lighting Patterns:

A lighting pattern pertains to how the light and shadows fall across the face. We all know that harsh outdoor lighting can be unflattering to our subjects, casting deep shadows under the lips, in the eye sockets and neck area. By using studio lights we can create pleasing light patterns with rich tonal value to accentuate our subjects facial contours. Different lighting set ups work better for women and men separately, and it is important to know the basics, once you have an understanding of basic light patterns you can begin to experiment and achieve the results you desire in each of your portraits.

1: Split Lighting

Split lighting is a simple, single light set up. It is called split lighting because it divides the face into light and dark areas. This setup tends to be rather dramatic in effect. To achieve this look the light is placed 90 degrees to the left or right of the subject. Any lighting pattern can be used on any facial position, but the light may need to be moved in relation to the subjects face for best results.

Term Definition - Catch light: Sometimes the subjects eyes may be too dark in a split lighting set up, so often a "catch light" is used in front of the subjects eyes to fill the reflections in their eyes and to avoid a "dead" look in their eyes. This catch light can be a big diffused umbrella light, not bright enough to affect the split light set up, but just enough to cause some reflection in the eyes, brightening up the subjects look over all.

2: Loop Lighting

Loop lighting is when lighting is positioned to create a shadow of the viewers nose falling across the face. To create this look the light position must be slightly higher than eye level and about 30-45 degrees from the camera. This positioning may need to change with each person, everyones face is different. Learn to read your subjects face, in loop lighting the shadow of the nose and the shadow of the cheek shouldn't touch. Adjust light as needed to achieve this. Loop lighting is a common method as it is usually flattering to the subject and is easy to achieve.

3: Rembrandt Lighting

So named because the same lighting is used in Rembrandt's paintings. This set up is identifiable because the shadow created by the nose and the cheek do touch, creating little triangle highlights under the subjects eyes. Proper Rembrandt lighting should also use a catch light on the shadow side of the face to keep the eyes from looking lifeless. This is a dramatic lighting set up that creates a deep mood. If your subject has high cheekbones this is a good method, if their nose is very short or shallow you may need to adjust your lighting to achieve the light triangle so endemic of this method. To create Rembrandt lighting the subject must turn slightly away from the light and the light must be above the top of the head. Not everyone's face is ideal for this method, so do what looks best and is most flattering.

4: Butterfly Lighting

This lighting setup is named because of the butterfly shaped shadow that is created under the subjects nose. In this setup the light is placed above and behind the camera. This setup is used for glamour lighting and to create shadows under the cheeks and chin. It can be flattering for older subjects as it tends to minimize the shadows in wrinkles, which would be more pronounced in side lighting. Sometimes in Butterfly lighting a reflector is placed under the subject, sometimes the subject will hold the reflector themselves. This pattern flatters subjects with thin faces and high cheekbones.

Studio Light Styles / Broad Lighting:

Broad lighting isn't a pattern itself but a style of pattern, any of the above patterns can be broad or short. Broad lighting refers to the subjects face being turned away from the camera so that the lighted area of the face is broader and the shadow areas are smaller or shorter. This type of lighting can make a persons face appear wider and may not be flattering, or it can be used to make a thinner persons face seem fuller.

Short Lighting:

Short lighting is the opposite of broad lighting, the subjects face is turned towards the light making the shadow area smaller, and often more flattering. It puts more of the face into shadow, adds depth to the image and tends to me more slimming and flattering.

Studio Lighting Assignment:

Pair up with 3-4 others and sign up for some time in the studio. We only have one studio so we will need to share. When you use the studio be extremely careful when handling the lights to avoid broken bulbs and broken equipment. Take turns acting as models and create examples of the following light setups:

• Split lighting
• Loop lighting
• Rembrandt lighting
• Butterfly lighting
• Broad lighting (in any pattern)
• Short lighting (in any pattern)
• Experimental (choose a light position/pattern/technique and get creative with it)

Post process or shoot your images as B&W images to demonstrate the proper lighting patterns, B&W can show tonal patterns and light/dark areas with more clarity than a color image. Post your 7 best results to your blog when complete.

Have fun!

Principles of Exposure: ISO and Noise

Assignment: Understanding ISO

Students, your new assignment is a challenge for you to demonstrate an understanding of ISO and how to adjust both Aperture and Shutter Speed to maintain proper Exposure across multiple ISO settings. In this assignment you will find a still life subject, and shoot 4 images that have similar exposures but increase in ISO. Little change should be seen in light/dark values, only additional grain/noise should be noticed as increasing. Overlay your images as shown below and document your exposure settings.

Notice the increase in shutter speed and decrease in aperture size that was required to maintain exposure levels across the 4 iso ranges

Reading and resources for deeper understanding:
Lightstalking: The Rule of Equivalent Exposure
Exposure Calculator 

Assignment Deliverables:

Part A:

1. Produce a series of images (4) that demonstrate the impact that ISO has on the noise in an image while maintaining consistent exposure. Choose a creative still life subject and produce 4 images showing the range of ISO settings from low to high. Mimic the ISO Comparison images above. You will need to adjust either shutter speed or aperture to keep even exposure, don't let the different examples get darker or lighter.
2. Compile the images in slices to show the even exposure levels, as illustrated above

Part B: 

1. Written Synopsis of the Exposure Principals. Write a short 3 paragraph description of the three principals of exposure, shutter speed, aperture and iso, what they mean and how you utilize them in photography. 
2. Email your essay to the instructor for credit

Principles of Exposure: Aperture, depth of field and focus

Exposure: Aperture

Notice in this chart that the wider apertures have a narrow DOF, while the smaller aperture has a larger DOF. Additionally the shutter speed must be sped up or slowed down depending on aperture setting.

Aperture is a mechanical feature on the camera lens that adjusts the amount of light that is let into the camera. The size of the aperture also changes the depth of field range, a term for the area of an image that is in focus. 

A larger aperture will create a narrow depth of field and allow the maximum amount of light in the camera, so a faster shutter speed may be used. This is great for artistic images, street photography, portraiture and still life. The depth of field can be very slim with a wide open aperture resulting in more emphasis on the subject.

A smaller aperture is used when the depth of field must be wider. This also allows a sharper image to be captured because the flatter part of the lens is being used... resulting in less distortion fringing of details. Great for images that need increased detail, landscapes, nature photography, architecture.

When a smaller aperture is being used to control depth of field, adjusting the focus on the lens can change the position of the DOF. You can move the DOF closer or farther away. Many lenses will focus automatically, but you can disable that to adjust the focus yourself.

Our artistic element of the week is "Value". Value refers to the tonal quality of an image, tonal quality is, IMHOP best evaluated through a black and white image. If you shoot in black and white or experiment with black and white conversion with an image editing program, you will learn to see opportunities for good value in b&w photography. Good tonal quality should show as many levels of value as possible, from bright to dark and everything in between.

Key Assignment 6: Aperture and Value

Students, your new assignment is to develop an understanding and demonstrate control of depth of field. Additionally we are focusing on value in photography by shooting black and white imagery

Assignment Deliverables:

1- Depth of Field Portrait: Create 2-3 portraits that demonstrate depth of field. Use a wide open aperture setting and look for good backgrounds for your subjects

2- Near/Far Focus: Arrange 2 people 10 feet apart from each other. Produce 1 image that shows the subject closest to you in focus, then change your focus to show the subject farthest away from you in focus.

3- Value/Contrast through B&W: Set your camera to shoot in Black and White only. Take 1 photo each day of the week that captures "value". Look for interesting compositions, light, contrast, patterns. You will need to shoot many images and experiment so you can learn to "see" in B&W value. Post your best 5 photos before next class.

Principles of Exposure: Capturing Action and Controlling Motion Blur

Exposure: Shutter Speed, Aperture, ISO:

Exposure is the measure of light falling on the media, be it film or CCD. It's controlled by three factors namely shutter speed, aperture and sensitivity of the sensor (ISO). Let me try to explain each of these in a greater detail.

Shutter Speed is the amount of time the shutter screen remains open, in other words, it is the duration for which the light hits the media. Shutter speed is the feature of the camera and not the lens. Faster the shutter speed, lesser the duration for which light hits the sensor, so lesser amount of light is captured.

The shutter speeds range from 1/4000th of a second (1/8000 on a pro camera) to 30seconds, with a special "B" (bulb) mode wherein the shutter could be kept open as long as the photographer wishes (of course, constrained by battery).

The shutter speed controls another most important aspect - freezing the subject in time. Simply stated, you shoot a speeding car with slow shutter speed, you tend to see the trails of the car resulting from motion blur. On the other hand you shoot the same car with higher shutter speeds, the car will appear as though it is stationary. In case you're wondering what magic, the photographer has done to capture those long trails of headlights, the answer is simple: he would have just kept the shutter open long enough to capture the trails.

When you're shooting with slower shutter speeds (under 1/100th of a second) holding the camera, it is highly likely that you end up with a blurred photograph. Why? It's obvious that when you're shooting at lower speeds, even the slightest camera shake will contribute to the blurring of the photograph. Solution for this problem is to mount the camera on a tripod or try to find a platform nearby to place the camera and shoot.

The answer for the question "What shutter shutter speed to use for a particular shot?" is "It entirely depends on the kind of shot and it can't be generalized". If you're shooting birds, wildlife, sports, street shots etc. which require the moment to be captured tack sharp use high shutter speeds. Night shots, trail capture, abstract photographs, light painting, milky waterfall photographs etc. require slow shutter speeds.

Aperture is the feature of the lens and has nothing to do with the camera, except that the aperture values are set/controlled by the camera. As the name itself suggests, aperture is an "opening" at the rear end of lens through which the light enters the camera. Earlier days, the lens barrel had an aperture ring to set the required aperture values, but these days the aperture could be controlled by the knobs on the camera or changing a setting on the digital menu of a DSLR.

The maximum and minimum value of aperture depends, as mentioned earlier, on the lens and not on the camera. You may find a lens with aperture as big as f1 or f1.4 or as small as f45 or f64. Aperture is measured in terms of f-stops and hence the f. It's notated f/1.8 or f/5.6 as well. As you can see the size of the aperture is inverse to the value of f-stop, higher the f-stop smaller the aperture, smaller the f-stops bigger the aperture. So at f1.8 the light received by the medium will be more than f5.6; least light will be received at the smallest aperture say F22 of F45 or whatever your lens supports.

Like shutter speed, aperture also controls one other aspect, apart from the amount of light, it's called Depth of Field (DOF). You maybe confused by amateur photographers who are fond of terms like DOF, Bokeh, Hyperfocal distance etc. Just remember this rule of thumb & don't get lost in the jargon: Bigger the aperture, smaller (shallower DOF) the region of focus; smaller the aperture larger (deeper DOF) the region of focus. You may, therefore, want to open up the aperture for a portrait shot wherein you want a focused and sharp face and blurred background and close down the aperture for a landscape shot wherein you want the entire landscape to be focused. Also in macro shots, the amount of DOF is very critical since the available DOF is very less. DOF is used sometimes to give artistic effects to the photographs.

Portraits would come out well with bigger apertures (smaller f-stops) for it makes the subject really sharp against a background of soft background, Also night shots usually require bigger apertures which would allow lot of light to enter.

Landscapes need smaller apertures (bigger f-stops) for most times it wouldn't have a specific focus point. Smaller apertures help on a very bright day to cut-off excess light entering (of course this could be controlled by shutter speed too).

ISO is the measure of sensitivity of the media (film) and digitally is a camera dependent feature. ISO values are typically in the range of 100 to 3200 (on a pro camera it can have an extended range from 50-102400)

When the ISO is set to 100 the sensor is the least sensitive, it can sense less light. When it's set to 1600 or 3200, the sensor can sense a much more light. Which means for a given condition if ISO 100 gives a standard exposure with F8.0 & 1/250th of a second, ISO 1600 may give a standard exposure at F8.0 & 1/1000th of a second. ISO comes very handy while shooting hand-held under low light conditions, it gives an advantage of slightly faster shutter speeds which helps in avoiding motion blur.

An obvious question may arise to a novice, "Why should I shoot at low ISO when higher ISO gives an advantage of faster shutter speed?" Though ISO seems to be such a cool feature, it carries with it something very undesirable - NOISE. Higher the ISO, higher the noise.

Brighter the ambience smaller the ISO (unless you want grainy effect), darker the ambience higher the ISO.

To Make It Easy Just Remember The Rule of Equivalent Exposure: Each Change In ISO Is Equal To One Full F-Stop

Imagine you've pointed your camera at a scene and it's recommending the following settings:

1. A shutter speed of 1/100s 
2. An aperture of f/5.6 
3. A sensitivity setting of ISO 400 

We could make the photo appear twice as bright by doing any of the following:

1. Doubling the shutter speed to 1/50s 
2. Doubling the area of the aperture by increasing it one full f-stop, to f/4 
3. Doubling the sensitivity setting to ISO 800 

Any of these could be described as increasing the exposure by 1 stop.

Likewise, to make the scene appear half as bright, we can reduce the exposure by 1 stop by taking one of the opposite steps: 

1. Halving the shutter speed to 1/200s 
2. Halving the aperture area by reducing it one full f-stop, to f/8 
3. Halving the sensitivity to ISO 200. 

Note that we use the word "stop" even when we're not adjusting the f-stop (aperture) setting. It's just become a general term to mean a factor of 2.

That's about it. For even more information, read this page here at Cambridge In Colour.
