Review Global corrections

Global corrections adjust the entire file. In the Lightroom, it includes the controls under Light, Color and Effects. In Lightroom classic, this includes everything in the basic panel: White balance, Tone and Presence.

Local corrections

After you make global corrections, sometimes you will want to make corrections to part of your image. Generally, the brightest part of the image commands the most attention. Sometimes that is not where you want your viewer to look first so shifting the exposure of parts of your image can create the image you want.

The two main tools for local adjustments are the adjustment brush and the graduated filter.

The important thing in this photo by Bryan Rodriguez is the face of the card player. However the cards are brighter and demanded too much attention. Using the adjustment brush, I darkened the cards. Creating a second adjustment, I lightened the face of the card player a little more. The goal was to bring more attention to the person’s face and less to the overly bright cards.

Final Project

Due next week, December 14th:

3 albums each of a minimum of 30 photos

1 album of the 10 best photos of the 90 total, adjusted in Lightroom

a 3-5 min presentation of the final project – projected from the album on Flickr.

Presentation Guidelines

1. Start by introducing yourself and your project. Then outline the big picture with a few sentences sentence such as, ” I photographed variations on the theme of windows. Most of the photos were taken in downtown Brooklyn.
2. If you are showing 10 images, you have about 30 seconds to describe each photo. Tell us what your intention was, what interested you about the photo we are looking at, and give us information we may need to know to understand the photo. Tell us what makes it visually interesting ie the use of shallow depth of field or some other feature.
3. How do you get to Carnegie Hall? Practice.
4. Do not tell us about what you did to the photo in Lightroom.

Sprint Campaign: http://lightpaintingphotography.com/?s=sprint 

Tripod use

• Spread the legs out and make sure the tripod is stable. Use the height from the legs before using the neck of the tripod. Put one leg forward and the two legs on your side.
• Put the plate on the camera and make sure that the lens arrow is pointing towards the lens. Insert the plate into the locking mechanism and make sure that the camera is secure.
• Use the camera timer and DO NOT TOUCH the camera or the tripod during the exposure.

Considerations for painting with light: 

1. Use a tripod 

2. Use Manual as the shooting mode.

3. Set the ISO to 100

4. Set the aperture to f/11 as a starting point to get a wide range of depth of field. 

5. Set the shutter speed to 2″ as a starting point.

6. Use manual focus. Make sure the subject is in focus. To do this shine a light on the subject and use auto focus. Then flip the lens back to MF. Remember that if the distance of the subject to the camera changes, you need to refocus!

Mixing Strobe Lights or Flash with Painting with Light 

The aperture controls the exposure of whatever is lit by the strobe lights. 

The shutter speed controls the illumination of the background. 

Lab

Working with a light or lights, draw an image over time in the frame. Experiment with thin and thick lines, abstraction, words, and images.

Using a speedlite, add a person to your shot. the more the subject and the light painting interact, the more successful your photos will be.

Upload a minimum of 20 images to Flickr. Send your best two to the class group.

Quiz Review

There will be three technical questions. Possible topics: light quality and direction, still life lighting rules, roles of the main and fill lights, difference between a reflected and an incident light meter, portrait lighting styles, wide angle distortion, three-point lighting.

There will be a compare and contrast of two photos which will be graded on correct use of vocabulary including portrait lighting styles: Rembrandt, split, butterfly, broad and short light and rule of thirds, diagonal lines, leading lines, pattern, symmetry, figure to ground, contrast of light and dark, a frame within a frame, depth of field, angle of view.

Focal Length

The focal length of a lens is defined as the distance in mm from the optical center of the lens to the the sensor when the lens is focused on infinity. This varies on the camera and the lens.

Focal length controls: Magnification and angle of view

Focal length is described as short, normal ie close to human vision, or long.

Wide Angle Distortion-created when using a wide-angle lens AND the camera is very close to the subject. The object close to the lens appears abnormally large relative to more distant objects, and distant objects appear abnormally small and hence more distant – distances are extended. 

• 

Focal length and proximity to the camera affect how a person’s face looks in a photograph. A wide focal length and proximity between the subject and the camera create wide angle distortion and will distort a person’s features.

Think about selfie sticks. What are they for but to get the camera away from your face? This makes the photograph look more complimentary to the subject. This is really important with a cameraphone because it has a wide angle lens. The center of the lens and the sensor cannot be very far apart given the thin design of cellphones.

When working with a crop-frame sensor such as a Canon 60d, approximately 65 mm will be the most flattering to your subject.

Lights

  There are three basic types of lights (these are the physical lights not portrait lighting styles):

1. The Main or Key Light-This light provides the brightest illumination and casts the shadows

2. The Fill Light-this light brightens the shadows. It can be a reflector or an actual light.

This video shows how to use a reflector as the fill light.

3. The Separation Light or Background Light-creates separation between the subject and the background. This light can be aimed at the background or it can be aimed at the subject. If the later, it would be called a hair light. If accenting the edge of the face or shoulders, this light would be called a rim light or a kicker.

3-point Lighting

– standard lighting for portraits, video and film, uses all three: a main light, a fill light and a background light.

Expression

For family photos a smile is a must but not so for a portrait. It is however important that your subject look comfortable. It is your job as the photographer to talk with your subject and make them feel comfortable.

Focus

When shooting a portrait, the subject’s eyes must be in focus. Full stop. period.

•

Portrait Lighting Styles

There are a 5 basic lighting styles for portrait photography. Each style is defined by how light falls on the face.

1. Rembrandt Light – the model is face forward, main light is at 45 degrees and casts a light on the opposite side of the face to form a triangle on the cheek.

2. Broad Light-model’s face in 3/4 view-light falls on the side of the face with the visible ear. Good for controlling the reflections on glasses.

3. Short Light-model’s face is in 3/4 view, the light falls on the side of the face with the features. (Not on the side with the visible ear.)

Both of these are examples of short light.

4. Butterfly Light, Clamshell or beauty or glamour light-model is face forward, front light.

5. Split Light-model is face forward, the main light is at 90 degrees to the camera and falls on one side of the face.

Studio Lighting

Continuous lights – Always on. Can be tungsten, fluorescent, LED

Strobe Lights – Electronic flash. The light for the exposure is fired at the time of exposure.

White Balance

adjustment for the color of the light so that a white object will appear white

Metering

Reflected Light meter-measures the light as it falls on the camera. The camera meter is a reflected light meter.

Incident meter-measures the light that falls on the subject

Flash meter- is a form of incident meter but measures the light at the time of exposure. Use it to determine the correct aperture.

Three rules for still life lighting:

• There should be one set of shadows.
• the background should be far enough from the subject to light it separately
• if you do have shadows, use them in the composition

The main light– casts the shadows.

The fill light – brightens the shadows.

HW 8: Childhood

Light Quality

Direct light or hard light – the rays of light are nearly parallel and strike the subject from one direction creating hard edged dark shadows with little detail.
Examples: a spotlight, sun on a clear day, or a bare flash

Diffused light or soft light– the rays of light are scattered and coming from many directions. It appears even and produces indistinct shadows. Examples: overcast daylight, a light covered with tracing paper or other translucent material.

Directional/Diffused Light.   This light is a combination of directional and diffused light. The light is partially diffused yet it appears to come from a definite direction and creates shadows. The shadows are less harsh and contain more detail than in direct light. More subtle transition between light and dark areas. Examples: window light, sunlight on a hazy day, sunlight on a partly cloudy day or sunlight bouncing off a reflective surface.

Light Direction

Front light comes from in front of subject from the camera position and the shadows fall behind the subject not concealing any details.

Side Light comes from 90 degrees to the camera. it adds dimension and texture to the subject.

Backlight comes from behind the subject towards the camera.

2. Ask questions about your colleague’s photography. This is not the time to ask questions about your personal concerns.
3. Start with the positive when you comment on your colleague’s works. Use the terms below that we have learned this semester.
4. Be generous. Offer your thoughts. Your opinion and judgements are important. Do not leave the work of giving feedback to the others in the class.
5. Conversely, please do not speak over your classmates.

Vocabulary

Framing: How the frame brings together the elements inside the rectangle juxtaposing them, creating relationships between them

Types of shots: how much information is in the frame

• a long shot
• a medium shot
• a close up
• an extreme close up.

Frame within a frame – use elements in the frame to enclose the main subject and draw attention to it. A frame within a frame can be a window or door or it can be items in the foreground such as branches.

Angle of View:  describes the camera position in relationship to the subject. The angle of view may be: 

• a worm’s-eye view
• a low-angle
• eye-level
• a high-angle
• a bird’s-eye or aerial or overhead view
• an oblique angle.

Rule of Thirds – Instead of placing the main subject in the center of the frame, divide the frame into thirds horizontally and vertically and place the main subject at one of these intersections.

Fill the Frame –  (get closer) – do not leave empty areas that do not add to the composition and plan to crop in later.

Diagonals – Sloping lines

Leading Lines – lines in the photograph that lead the eye to the main subject

Patterns – repeated elements. Break the pattern for visual interest

Figure to Ground -the relationship between the subject and the background sometimes described as negative and positive space.

Diffused light – light that comes from many directions and creates soft shadows

Direct light– light that come from one direction and creates hard shadows

Contrast: The measure of difference between bright areas (highlights) and dark areas (shadows) in a photo

High contrast : Large difference between highlights and shadows. Mostly lights and darks without many mid tones        

Low contrast :  Little difference between lights and darks. Mostly mid tones.

Frozen Motion-Motion is stopped and captured in the frame with a fast shutter speed.

Blurred motion-moving elements blur with a longer shutter speed.

The Decisive Moment: A term coined by Cartier Bresson- “the simultaneous recognition, in a fraction of a second, of the significance of an event as well as the precise organization of forms which gives that event its proper expression.”

Terms

Aspect Ratio-the proportion of the width of the image to the height of a 2D image

Clipping-the intensity of the light falls outside of what can be recorded by the camera and there is a loss of detail.

Color Profile-the data for a digital device, such as a printer or monitor, which describes its gamut, or range of colors. Used to match the gamut from one device to another.

Exif Data-information stored by the camera in the file.

Gamut-range of colors

Histogram- a graphic representation of the tones in an image. A spike of data on the left side indicates underexposure, on the right overexposure.

Neutral Value-RGB values are equal or gray

Non-destructive Editing-adjust the image without overwriting the original image data. Instructions are written to a sidecar file that tells the software how to interpret the image.

White Balance-the setting that adjusts for the color temperature of the light and that will make a white object appear white or a gray object a neutral value

Global Corrections

Global corrections adjust the entire file. In the Lightroom CC, it includes the controls under Light, Color and Effects. In Lightroom classic, this includes everything in the basic panel: White balance, Tone and Presence.

Using the Histogram

The histogram is a graphic representation of the tones in the photograph. It is a guide to exposure decisions. Most images look best when there is a full range of tones from black to white in the image. But there are no iron clad rules.

To access the histogram in Lightroom, from the keyboard select: Command 0

Or get it from the three dots on the right menu bar.

From the top of the histogram, there is a triangular button. Toggle it to turn on/off show clipping.

To maximize the the tonal range, adjust a photo to have some tones that are totally black and totally white but only a few so that you don’t lose detail in either the shadows or the highlights.

• 

Looking at the histogram, we can see that there is not a true black or white. To raise the contrast of the image and use the full tonal range, use the following adjustments:

• Select show clipping on the top left of the histogram. Adjust the blacks slider to the left until you see bright blue flecks on your image.
• Select show clipping on the top right of the histogram. Adjust the whites slider to the right until you see bright red flecks on your image.

Most images improve with:

• shadows slider to +50 add detail to the dark areas
• the highlights slider brought to the left to bring detail into the highlights.
  

In this photo of the pier in Coney Island, the histogram shows that is underexposed. But we also know that it is an evening scene and that there is nothing in the photo that should be bright white.

• 

Lightroom Workflow:

1. Optics: enable lens correction. If there is architecture or a strong horizon line, geometry>upright>auto
   
2. Crop.
   
3. Color. Adjust the white balance if necessary.
   
4. Light
   a. Exposure slider-use to adjust the overall tonality
   b. Set black point using show clipping
   c. Set white point using show clipping
   d. Use shadows slider to brighten mid tones.
   
5. Effects – Adjust clarity (mid tone contrast)
   
6. App: color – Adjust vibrance and or saturation
   
7. Detail panel – Sharpen-amount at least 50
   

Lightroom Classic Resource

A few tips for Lightroom Mobile:

1. To access the histogram, tap on the image with two fingers. If you can’t really see the histogram background, brighten the display.
2. To see the image before your corrections, press on the image.

Light and Dark

The word photography is rooted in Greek meaning “ writing with light “  One of the main concerns of photographers is how light illuminates a scene or subject. While we focus attention on light, it’s easy to not pay attention to shadows. Shadows, although dark, can be as dynamic as light. The shadows shape light, define texture, and act as compositional elements. 

Contrast: The measure of difference between bright areas (highlights) and dark areas (shadows) in a photo

High contrast : Large difference between highlights and shadows. Mostly lights and darks without many mid tones                

Low contrast :  Little difference between lights and darks. Mostly mid tones.

Shadows –  dark areas in photo that can range from black with no detail to dark tone with detail

Uses of light and shadow: Light and shadow are complementary elements in photography. The quality and direction of light affect how a subject looks while  producing shadows in various forms

1. Contrast and Drama :  Shadows can be used to create contrast to produce a dramatic effect. Attention of the viewer is drawn to tonal contrast which can not happen without shadows. In this interplay of light and shadow, the lighting effect is enhanced by the shadows.  

2. Shadows can be used to direct the viewer’s attention. Shadows can be be shapes that may be used as compositional elements  to direct attention to the center of interest in a photo. Also shadows can surround a light area to make it a center of interest.

3. Reveal form: Using shadows will give form to subjects and make them look more three dimensional. The shadows don’t necessarily need to be black for this to happen. As long as one part of subject is light and one part is darker the photo will look more three dimensional. For dramatic effect, direct light will produce dark shadows. But for some subjects, dark hard shadows can be distracting or cause loss of detail. For subjects where detail is important, using partially diffused light will make soft shadows that will show form and maintain detail. 

4. Reveal texture: Side light with shadow will show texture

5. Shadows can be shapes and patterns that can be used to complete a composition.

How light falls on your subject is key to using shadows in photography. The best direction for a combination of light and shadow will be light coming from the side. For dramatic effect photograph when the light( direct light ) is at a lower angle which  will produce longer dramatic shadows. For less dramatic effect, use diffused light.

Exposing for photos that contain light and dark areas you will need to use exposure compensation. If there is large dark areas in the photo, the meter will over expose the light areas. In this case you need to use exposure compensation to lower the level of the lighter areas.

Quiz 1

Next week on Oct 19th, there will be a quiz. Review the class topics pages for weeks 1-6.

Light Quality

Light is either direct or diffused.

Direct light: the light strikes the subject from one angle and creates sharp shadows. Sunlight is an example of direct light.

Diffused Light: the light hits the subject from many angles and creates soft shadows. The light is diffused on an overcast day or in the shade.

• 

• 

• 

• 

• 

• 

Measuring the Light

Exposure is the amount of light that comes into the camera to create the photograph.

Exposure is made up of three components:

1. ISO-Sensitivity to light.
2. Shutter Speed-the length of time that the camera’s shutter is open during the exposure.
3. Aperture-how wide the cameras lens opens to allow the light to come in.
   

All three are measured in stops.

How your Camera Meter Works

Acronym: TTL – Through the Lens

The meter in your camera is a reflected-light meter.

A reflected light meter averages the tones in the scene and selects the aperture and shutter speed values that will make the whole scene medium gray.

Watch from :45 to 1:34 for an explanation of how your camera meter works.

Challenges

There are certain predictable situations that will fool your meter.

1. Backlight – a common example is a person against a window or against the sky. Add exposure to get the right exposure for the main subject and allow the background to be overexposed.

• 

• 

2. Landscapes with sky. The sky is brighter than the ground and to get a good exposure of the land portion of your photo, often you need to over expose the sky.

• 

• 

3. Snow

How to control exposure

With a camera: Use Exposure Compensation set to plus to increase the light and set to minus to decrease the light.

Exposure Compensation-a way to force the camera to make an exposure either lighter or darker than the meter reading. Good for backlight or extremes of light and dark.

With a cameraphone: Touch the area where the main subject is and then drag the little sun icon up or down to increase or decrease the overall exposure.

Using Exposure for Creative Effect

Sometimes, you don’t want the tones in your image to average out to a medium gray. You want to tones to be low key-mostly dark or high key-mostly light.

Shutter Speed is the length of time that the sensor is exposed to light to create the photograph. It is measured in seconds or fractions of a second.

The full stops for shutter speed are: 30”, 15”, 8”, 4”, 2”, 1”, . sec, ., 1/8, 1/15, 1/30, 1/60, 1/125, 1/250, 1/500, 1/1000, 1/2000, 1/4000, 1/8000

Doubling the time, doubles the amount of light that reaches the sensor.

When shooting with a cameraphone and the Lightroom Photoshop app, you can set the shutter speed of your cameraphone between 1/10,000 and 1/4 sec.

A good rule of thumb when shooting with a camera is: Any shutter speeds slower then 1/60 require the use of a tripod. When shooting with a cameraphone, you will need a tripod to shoot at 1/15 or slower.

Resource

Capturing of Motion

Your choice of shutter speed will change the way motion is captured in the photograph.

Frozen Motion-Motion is stopped and captured in the frame with a fast shutter speed.

• 

• 

• 

• 

How to freeze motion:

• Use a shutter speed of 1/ 500, 1/1000 or faster.
  

Blurred motion-moving elements blur with a longer shutter speed.

• 

• 

• 

• 

• 

• 

How to blur motion:

• Use a slower shutter speed – 1/4 sec to 30″ or even longer
• Direction-if the subject moves parallel to the picture plane there is more visible movement than if the subject moves toward or away from the camera.
• Focal length-a subject will appear blurrier when photographed with a telephoto lens than when photographed with a wide-angle lens.

Timing

The exact moment that you take the picture is as important as how long the shutter speed is. This is often called:

The Decisive Moment: A term coined by Cartier Bresson- “the simultaneous recognition, in a fraction of a second, of the significance of an event as well as the precise organization of forms which gives that event its proper expression.”
