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, Exposure, 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 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.

• 

The main tools for local adjustments are the adjustment brush, the radial filter, the graduated filter, and the select sky and select subject masking tools.

Homework

Final Project

1. Final project statement and mood board

2. 3 albums each of a minimum of 30 photos

3. 1 album of the 10 best photos of the 90 total, adjusted in Lightroom

4. 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. Give us the big picture in a few short sentences 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. Practice your presentation.
4. Try making a simple notecard for each image that lists the one or two points you want to make about that image.
5. Do not tell us about what you did to the photo in Lightroom or what would have made the photo better.

All the World Photo contest

4 pts

The contest submission consists of three portrait photos, a short bio of 100 words of each subject and a photo release form for each one.

If you want me to edit your bios, email them to me by May 22nd.

Due on May 24th

Your final submission including the three photo releases and proof of submission.

Terms

Ambient Light-the existing light that you cannot control

Stop-measurement of exposure by a factor of 2. One stop more doubles the light. One stop less reduces the light by half.

Exposure Triangle-the interchangeable association of ISO, Aperture and Shutter Speed

Strobe Basics

Strobe Lights or Flash-The exposure triangle does not hold because the shutter speed is effectively replaced by the flash duration. We adjust the exposure primarily with the aperture or the ISO.

Sync Speed-is the fastest shutter speed for which the shutter curtains are completely open at the time of exposure (or when the flash fires). For shutter speeds above sync speed, the shutter curtains are no longer fully open.-Dpreview.com

Flash duration-a measurement of the length of time of the burst of light that makes the exposure. This is how long the light is actually on. With our Dynalight strobes this is about 1/450th of a second at full power. Canon speed lites are about 1/313 at full power but 1/4,950 at 1/8th power

The sync speed of the class cameras is 1/200. To get around this, use: 

High speed sync-allows the camera to be set at shutter speeds higher than the camera sync speed 

DO NOT fire the flash in huge bursts when using high speed sync! If the flash becomes hot, let it cool down before using again.

Settings:

E–TTL (Evaluative-Through The Lens) is a Canon EOS flash exposure system that uses a brief pre-flash before the main flash in order to obtain thlo 7 `e exposure.

M-Manual-Set the power of the flash to full power, 1/2 power, 1/4 down to  1/128 power. The difference between each setting is one stop.

Zoom-you can spread the light over the scene or focus it by setting the zoom. A number that corresponds to a wide focal length like 28 mm will spread the light. A number corresponding to a telephoto focal length like 200mm will create a narrower beam of light.

Exposure-For consistent results use M shooting mode.
1. Figure out the exposure without the flash. If you want shallow depth of field use the widest aperture then figure out what shutter speed you need. On a bright sunny day, you should be able to shoot at 100 ISO. 

2. Stop down one or two stops depending on the look you want. 

Off-camera Flash

Put your flash on the channel that matches the trigger and receiver.

SAAF-Shutter Ambient, Aperture Flash

Shutter speed will control the illumination of the background.

Aperture will control the illumination of what is being lit by the flash.

Make the shutter speed faster to make the background darker when shooting with flash.

All the World Photo contest

Due on May 17th

The contest submission consists of three portrait photos, a short bio of 100 words of each subject and a photo release form for each one.

Put a small jpg with your 100 word bio for each subject on Google Drive and share the document with me: robinmichals@gmail.com before noon on May 17th.

Due on May 24th

Your final submission including the three photo releases and proof of submission.

Flash Basics

Ambient Light-the existing light that you cannot control

Fill Flash-brightens shadows

Built-in flash-part of the camera and throws light about 6 to 10 feet

External flash-added to the camera on the hot shoe and can throw light 15 to 20 feet 

E–TTL (Evaluative-Through The Lens) is a Canon EOS flash exposure system that uses a brief pre-flash before the main flash in order to obtain a more correct exposure.

Fill Flash

Use M or manual.

1/1 is full power. Full stops are 1/2, 1/4, 1/8/ 1/16, 1/32, 1/64, 1/128.

Use Zoom to spread or focus the light. Wide angle numbers (smaller numbers) spread the light as for a wider shot with a wide angle lens. Higher numbers focus the light for a telephoto shot.

High speed sync-allows the camera to be set at shutter speeds higher than the camera sync speed
