In regards to Photoshop 4, if you could recommend one feature for me as a beginner to concentrate on, that was pretty basic, but enhanced photos tremendously, what would it be?

As a beginner in Photoshop, one feature that you can focus on to enhance photos tremendously is the "Brightness/Contrast" adjustment tool. This tool allows you to control the overall brightness and contrast levels of an image, which can greatly improve its appearance.

To access the "Brightness/Contrast" adjustment tool in Photoshop 4, you can follow these steps:

1. Open the image you want to edit in Photoshop 4.
2. Go to the "Image" menu at the top of the screen and select "Adjustments."
3. In the dropdown menu, choose "Brightness/Contrast."

Once you have the adjustment tool open, you will see two sliders: "Brightness" and "Contrast." Here's how you can use them:

1. Adjusting Brightness: Move the "Brightness" slider to the right to increase the brightness of the image, or move it to the left to decrease the brightness. Be careful not to overdo it, as excessive brightness adjustments can result in loss of details.

2. Adjusting Contrast: Move the "Contrast" slider to the right to increase the difference between light and dark areas, making the image more vibrant and defined. Move it to the left to decrease the contrast and create a softer or muted effect.

By experimenting with these two sliders, you can refine the brightness and contrast levels of your photos until you achieve the desired look. It's a basic yet powerful tool that can make a noticeable difference in enhancing your images.
