PS curve color curve can replace the color order and brightness contrast

Color level is the gray field white field black field, by adjusting the three kinds of pixel points to adjust the overall brightness of the picture.

The adjustment of the section has three points, above is a histogram, through the graph, you can see the whole picture pixel distribution. Can be moved by three points to achieve the purpose of adjustment.

Photoshop curves, unlike levels of color, can divide the entire picture into 14 categories for adjustment. This classification is the System division, the color order is three kinds of black and white ash, the curve classification is your own definition, the adjustment part has a line, may add the above point to move downward, to adjust the picture that dot pixel brightness. You can add up to 14 dots on a straight line, which is equivalent to dividing all pixels into 14 categories.

Brightness/contrast, overall adjustment of brightness and color contrast degree

When you adjust it, you can use it directly.

Hue/saturation is not the same as the top three, which adjusts the color.

Adjustment, the following has a color can be selected, after the election, adjust hue, you can change the overall color of the picture.

Curve

In the past in the adjustment of photos, must use the color stage, brightness ratio, curved line, three of each other with the use of each other, but after the Photoshop CS3, the curve has been able to choose the big beam, why so say? The main reason for this is that after Photoshop CS3, the curve has changed a lot, That is, there is also a hierarchy in the Curve panel, which is really a creative! So now as long as a curved panel, you can at the same time with the color and brightness ratio of the function, then the plum dry will come for a little trial, I hope to be back when you're finished, and you have a deeper understanding of the curve, and the next time you use it, everything else feels the same. The control point in each curve has its meaning.

The curved control Panel of the CS3 below is clearly visible from the panel, and the middle is also shown as a mountain-like color map, this is the same as the chevron in the color hierarchy, and the other curved panel has two important things, that is, the input, the output, the so-called input is the color of the original image, output is the adjustment of the color hierarchy, And the middle gray of the middle 128 is the 18% reflectivity of the so-called camera, so today, when you set up a control point on the curve and drag it up, the image will be brighter, mainly because the input color is 128 gray, and when the curve pulls up, it outputs 250 溁 GUI R, As the 128→250 will be nearly 1 time times higher in color, the whole picture is much brighter.

Correction of the light and dark ratio of the image

When you start to adjust the photo, you will open the palette, check the Chaliang, the dark points, and if you find the dark dots in the photo, the left and right triangle control button will be placed on the two side of the Chevron, which is improving the image's ratio, so from the bottom you can see that the curve is finally done and the challenge is successful!

Increase/decrease brightness

When it's done, it's the control button from the middle to adjust the brightness of the whole image, and when it's right, the darker side of the match increases, so the picture gets darker and the opposite is brighter.

Increase brightness

To adjust the control button directly from the color hierarchy panel, on the right, the image becomes brighter, and as long as the level of the curve in the curved line moves up the curve, you can see the effect of changing the color hierarchy, so the challenge is successful!
