Don't be bashful! If you want comments, give comments. You don't need to be an expert photographer to express your opinion about the work of others. You don't need to go into great depth. A simple remark about cropping, composition, color, subject matter, etc. can be of just as much help to a budding photographer as an in-depth critique.
I covered a lot of ground quickly in this chapter to get you familiar with all of the kinds of light that affect the color and contrast in your images. For this assignment, you get to pick the light for your subject. You can take a high- or low-contrast photo. You can take the picture indoors or outdoors, in full light or low light. It’s up to you. The only instruction is to make note of all of the elements that go into the photo that you choose to upload to photoworkshop.com. What kind of light are you dealing with? Do you need to adjust the white balance? What are your shutter speed, ISO, and aperture settings? Do you have to adjust any of them to accommodate the amount of light? When you upload the photo, share with everyone all that you can about how you took your image.
