10:10 Photography – Your DSLR – Let’s Review

Let’s review some of the concepts from last week:

Vocabulary
Aperture Priority
Shutter Priority

Photography Formats

JPEG

When you shoot JPEG, a raw converter in the camera itself completes all the mathematical tasks to capture a certain color—then the raw converter compresses it . JPEGs apply heavy compression to color data, which can lead to problems with weird skin tone and such when editing time comes. It’s important to keep in mind that when shooting in JPEG, there’s very little you can do after the fact to interpret the color balance of your images.

RAW

When you shoot your pictures in RAW, those files provide the highest quality files. Here, everything is manual except ISO speed, shutter speed, and the aperture setting, which you may remember as the three main pillars of exposure. That means you, as the photographer, are in charge of tonal response, white balance, and colorimetric rendering, thereby giving yourself a great deal of creative freedom.

Let’s look at a raw file and do some touch up in Camera Raw. The image can be found in Public Folders
Called: Bryce_Storm.dng and Cathedral Valley Road and San Francisco Haze
Make a copy and place the copies on your desktop for now.
Open Bridge and then right click on the image to open in Camera Raw

The photo we are using is from: https://www.phototraces.com/free-raw-photos-for-editing/

When working in Camera Raw, we’ll need to set a baseline to begin our photo editing.

What we are basically going to look for when editing is whether we have blown out (overexposed or clipped) our whites (highlights) or crushed our blacks.

Areas we’ll look at include:

Histogram which displays the image tonality (how pixels are distributed). To the left are the darks and shadows and to the right are the highlights. The middle shows the midtones.

Exposure Slider is one of the first areas to adjust. This allows you to adjust the overall brightness of your image(exposure). Watch the histogram as you make all changes.

Blacks and Whites sliders help you determine the optimal highlights (whites) and the shadows (blacks). A good trick is to use the ALT key to see where the pixels begin to clip. It can be helpful to adjust past the point of pixelation, since it can show you how far you can push your whites (and blacks) without blowing out the image and losing detail.

Highlights and Shadows sliders are used to fine-tune your image. This is a creative choice. Lower the highlights slider to darken the brightest sections or increase to make your brightest areas brighter.

Luminance is all of the colors and the intensity of light from them. It measures how much white or black is present in the color(s)

Shadows will reveal the details in the dark sections of your photo

Strategies for Retouching photos

The amount you do depends on the image you are working with and your goals for it. Most retouching of photos includes these general steps:

Duplicating the original so as to have a copy on hand
Checking your image resolution for the ways you’ll use the image
Cropping to final size and orientation
Repairing flaws of damaged photos (rips, dust, stains, etc…)
Adjusting the contrast or tonal range
Adjusting color and tone to bring out highlights, midtones, shadows and desaturated colors
Sharpening of the image
Exporting and saving

11:00 English with Mx. Yopp – CANCELLED

11:55 Color Isolation – Image Manipulation

Selective color editing is a powerful technique that allows you to highlight specific colors within an image while converting the rest of the scene to black and white or desaturated tones.

By isolating certain colors and removing we can create visually striking images that draw attention to specific or certain elements. Doing so can communicate a particular mood or feeling.

Selective color editing is commonly used in fashion photography, conceptual art, and storytelling to make subjects stand out, create emphasis, or establish a visual narrative.

I’ve written up the process. Make a copy for your reference.

Color Isolation Assignment

Using Three of your own photos, find a subject to isolate. Edit and adjust your photo as you see fit. Then, when ready, isolate your subject and push the color and/or adjustments. Make it interesting and attractive.

Save each image as a jpeg in your files.

For final display, create a new project in Photoshop – 1920 x 1080 on white background. Place your images and add text: Color Isolation. You have creative control for final output.

This project will be due on Monday, September 16th.
