Describe the difference between direct and diffused light. Take and include in your answer an example of each one.
In both food and portrait photography, it is common to use a main light and a fill light. Describe the role of each of these lights. Take and include in your answer a photo that clearly has a main light and a fill light. The subject can be anything from an onion to a person as long as the two lights are clear.
Compare and contrast these two photographs of eggs. Be specific about how each photo uses the following conventions of food photography:
angle of view
lighting
depth of field

Select one of the photos that you will include in your final project that needs some local as well as global corrections.
First make the global corrections.
Then identify what is the most important thing in your photo. Consider how to best direct our attention there.
Then using the adjustment brush and or the graduated or radial filters, make the needed local corrections.
Put a before and after version of your file with local corrections into a gallery block in a post on OpenLab. Include a list of the global and then local corrections that you made to the file.
Pick any photo that you will be including in your final project presentation.
Make the necessary global corrections to make your photo look its best.
Put the before and after versions of your photo in a gallery block into a post on OpenLab. Include a list of the adjustments you made to the photo.

Lightroom Workflow:
Classic: Lens corrections and Transform panels. Correct lens aberrations and Transform, rotate and straighten. App: Optics, geometry.
Classic: Crop. Left below the histogram. Keep the lock on to maintain aspect ratio. App: Crop
Classic: WB on basic panel – Set white balance. App: Color
Classic: Exposure section on basic panel – Read the histogram to set exposure. Most images should have the widest possible dynamic range, meaning that there should be data across the entire histogram. App: Light Both: a. Exposure slider-use to adjust the overall tonality b. Set black point-shift double click. c. Set white point-shift double click. d. Use shadows slider to brighten mid tones.
Classic: Presence section of basic panel – Adjust clarity (mid tone contrast) App: effects
Classic: Presence section of basic panel – Adjust vibrance. App: color
Classic: Presence section of basic panel – Use saturation with care: +10 at most App: color

Global corrections adjust the entire file. In Lightroom Classic, this includes everything in the basic panel: White balance, Exposure, Tone and Presence. In the Lightroom/Photoshop App, it includes the controls under Light, Color and Effects.
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 and the graduated filter.
Selective Edits is a premium feature. You should have access to it if you have an account.
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
Start by introducing yourself and your project. One big picture sentence such as, ” I photographed variations on the theme of windows with most of the photos taken in downtown Brooklyn.
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.
Your presentation will improve if you practice.
Try making a simple notecard for each image that lists the one or two points you want to make about that image.
Do not tell us about what you did to the photo in Lightroom or what would have made the photo better..
Pick one of your best portraits shot with front light to work with. Create four versions:
the file exactly as shot
the file with the exposure adjusted
the file re-touched in Lightroom
the file re-touched with frequency separation
Put them in a gallery block in a post on Openlab with the category:
Lab: Week 13 – Re-Touching
No adjustments
Exposure +1. Highlights -35, Shadows +50
Using the histogram, first adjust the basic exposure. Most portraits will benefit from opening up the shadows to +50.
Re-Touching With Lightroom
Use the adjustment brush set to soften skin. Brush loosely over the expanses of skin avoiding the features.
Use the adjustment brush set to dodge dark areas such as under the chin and in this cas I also lightened the glasses shadow. Use the adjustment brush set to burn to lighten and bring detail into the hair.
The eyes are the most important feature. To make them stand out slightly:
Use the adjustment brush set to clarity to outline the eyelids.
Use an ajsutment brush to carefully select the iris and brighten.
Use an adjustment brush to carefully select the whites of the eyes and increase the exposure very carefully. Do NOT so this too much otherwise it will look very artificial.

Frequency Separation
Frequency separation allows you to re-touch the skin without losing its texture.
Set up the file:
Make two copies of the background layer.
Name the middle on Low and the top one high
Select the Low layer and then filter>noise>dust and scratches> 15 radius
Select the High layer and then image>apply image. Layer: low, blending: subtract.
Set blending mode to linear light.
Group the High and Low layers and name it skin.
Command-shift N to create a new layer. Mode>Overlay. Check 50% gray. Name it DB.
Add a B&W adjust layer on top and bring down the red channel to enhance the flaws.
2. Remove blemishes: On the High layer, using the healing brush, hold option to sample an area near the blemish. Then paint over it to remove it. Use this to remove stray hair.
3. Smooth skin: On the Low layer, uses lasso tool to select areas to smooth out. Filter>blur>gaussian blur> 15 radius.
4. Dodge and Burn: On DB layer, use the dodge (lighten) tool set to midtones>3%>protect tones. Us this to lighten bags under the eyes and brighten the eyes.
