·Adjustment layers

The Adjustment Layers in Photoshop are a group of a super useful, non-destructive image editing tools that add color and tonal adjustments to your image without permanently changing its pixels. 

You can edit and discard your adjustments or restore your original image at any time.

The brightness slider is for adjusting the highlights in your image and the Contrast slider is for adjusting the shadows in your image.

Levels modify the tonal values in an image by adjusting the levels of the shadows, midtones, and highlights.

Exercise 4（Week4: PRACTICAL DIGITAL COLLAGE）

WEEK 3 - PEN TOOL EXERCISE (BEST COMPOSITION）

DESCRIPTION:

The first time I came into contact with photoshop, I didn't think it was very good. First, I selected some pictures that I liked from the pictures sent by the teacher, and tried to arrange and layout them by using the cropping tool, etc. During the process, there were many problems, so I tried to find the answers in the guidance video. Although the process was very difficult, the result was not so bad.

WEEK 4 (ADJUSTMENT LAYERS & FILTERS )

DESCRIPTION:

When making a digital collage, the level tool in Photoshop can help me adjust the overall tone, contrast and brightness of the image. Using the level and curve tool allows the collage to make fine adjustments to the brightness, contrast and tone of the image, thus making your digital collage look more vivid and attractive.

FEEDBACK

week4

The assignment after changing the color tone seems more vivid than the original one, perhaps because the color gap has increased, all in all, I have fallen in love with this course.
