Difficult to calculate how many people now use "Photoshop5.5" - too many people using computers, using computer graphics too many people, almost all people who use computer graphics are more or less on Photoshop5.5 know ... ...
Asked a question mentally retarded: Photoshop5.5 What is the most wonderful thing?
Channel? Layer? Filter?
These answers are correct! But I thought: Photoshop5.5 most amazing is that "color adjustment." Oh, personal views, only for your reference.
Go take a look? ?
(Figure 1)
Figure 1, the menu is the "adjustment" command, he was in the "graphics" menu, which includes: Levels (Levels), Auto Levels (Automatic Levels), Auto contrast (Auto Contrast), Curves (curve adjustment), Color Balance (color adjust), Brightness / Contrast (brightness / contrast), Hue / Saturation (hue / color saturation), Desaturation (removal of color), Replace Color (replace color), Selective Color (select color), Channel Mixer (channel mixer), Invert (reverse), Equalize (equal), Threshold (threshold value), Posterize (color separation), Variations (changes) and other directives.
One, Levels, Auto Levels, Auto contrast, Curves, Brightness / Contrast mainly to adjust the contrast of the image, they can change the distribution of the image pixel values and can be adjusted in a certain range of colors. Levels, Auto Levels, Color Balance, Selective Color can adjust the image color balance degree, Hue / Saturation, Replace Color, Selective Color, Invert, Equalize, Threshold, Posterize, Variations and other instructions can modify the image in a specific color. Next, we were more of these instructions to make a statement ... ...
First of all, "Levels (Levels)" command ... ...
Now, we open an image, to look at Levels (Figure 2)
(Figure 2)
Under the Image menu select Adjust sub-menu "Levels" command, bring up Figure 3 expressed Levels (Levels command) dialog box.
(Figure 3)
The next several parts of the Levels dialog box to make a little introduction:
1, Channel Options bar
Let's look at what he is. (Figure 4)
(Figure 4)
Channel through the Levels dialog box, options bar (where the options will change with the image of the pattern), you can composite channel or adjust the color channels, respectively, also can adjust several color channels simultaneously (for example, "RG "He said that the red channel and green channel. way: hold down the Shift key while floating in the Channel window, select the channel). Your selection, Channel Options bar will show the selected channel abbreviation, such as RGB, RG, GB or CMYK, CM, CK, etc..
2, the image histogram.
Histogram of each image brightness according to value (0 ~ 255) Office distinguish between the number of pixels. White triangle on the right image of a dark part of the slider control, the left slider controls the black triangle part of the image of the light-colored, gray triangle slider to the middle of the middle of the image color control.
Move the slider to enable channel (selected channels) the darkest and brightest pixels into black and white, respectively, to adjust the image's tonal range - so you can use it to adjust the image contrast: the slider left to adjust the contrast of the image in shadow, the white triangle to the right to adjust the contrast of the image in shadow. On the left of the black slider to the right, the image become darker in color, contrast weak (to the right of the white slider to the left, the image faded color, contrast also become weak). Two sliders in the histogram of their respective ends of said high light and shadow.
As for the middle of the gray triangle slider, which controls the Gamma value, while the Gamma value of another measure of image contrast of the middle tone. Gamma values can be changed to change the image brightness values of the middle tone, but not on the shadow and bright areas have too much influence. The gray triangle slider to the right a little action can make the middle tone darker, moving slightly to the right middle tone can brighten. (In the Input Levels dialog box, the data that is representative of the middle tone value)
We take a look at the image (Figure 5), take note of Channel Options bar (for the R-channel), histogram of the triangular slider position and leaf diagram in Figure 2, the difference between the leaves.
(Figure 5)
3, Input Levels
I wonder if you noticed: When the histogram of the slider moves, Input Levels value box for the three different changes of their own.
In fact, a control is the "Input Levels." Direct numerical control in the input box, you can also use histogram of the triangular slider control.
You can use two methods to reset the image of high light and shadow. However, the Department of reset after high light and dark contrast of the problem may occur (usually the average color of the image will not have this problem, if the pixel value is concentrated in the gray value of the ends of the middle tone contrast there is a problem), we need Use the middle slider to adjust the contrast of the gray triangle.
4, Output Levels
Output Levels on the histogram below, there are two numerical input box next to who.
He shows the value to be output, and Input Levels as: You can use the numerical control, you can also use the slider control (though he was only two sliders: one black, one white). Black triangular slider controls the contrast of shadow images (from left to right data the first data box is the shadow value), the white triangle slider to control the image contrast of the bright part (the second value data box). For example, under the plan, the white triangle slider to 158, then the light department pixels (Input Levels in the 255) will become 158, while the lower image, the pixel brightness values will become correspondingly more dark pixels, or black triangle slider to 89, the shadow pixels (Input Levels in the 0) will be mapped to 89, and the image corresponding to other pixels will become more bright pixels.
With the view of Figure 6, please note that the figure of the value, the slider changes the position and image.
(Figure 6)
The next dialog box on the right side should be a few buttons ... ...
OK, Cancel, Load, Save how to use the four options, I believe not me, right? I only talk about the Auto (Automatic) This option Rights -
Auto option functions as Auto Levels command. Click him, Photoshop5.5 will automatically equal the "Levels" adjustment: will the brightest pixel is defined as white, the darkest pixel is defined as black, pro rata among the pixel color value (the default when 10% reduction in pixels, that identifies the image in the brightest and darkest pixels, pixels by 0.5%, respectively, to ensure representative values of white and black pixels).
However, this is a default view, you can change the default value of the natural Rights: Press the Alt key while you click the Auto button in the dialog box (press the Alt key once, Auto will become Option), transfer the Option dialog box ( Figure 7). Enter you think the appropriate percentage (range is 0.5% ~ 1%), "OK" OK.
(Figure 7)
Usually, Auto (Auto Levels) for simple comparison of the grayscale and pixel values of the average image. If the image is complex, manual adjustment can be made more accurate results - Oh, to steal a little lazy, "Auto Levels" also said in together friends, do not look do not understand it?
Finally, "OK"! On the line.
(Now the new image would have friends ... ... to re-open the Levels dialog box, you will see the new histogram Rights ... ...)
[Next]
In the previous section, because the lazy, the "Levels" and "Auto Levels" and spoke together, it touches save a lot of things. Tasted the sweetness of the natural want to secretly lazy: the "Auto Contrast" jump in the past ... ...
Do not blame me ... ... In fact, the "Auto Levels" and "Auto Contrast" has a "automatic" the word, I just want to say also that there can not go Well, Who he is "automatic" again? ... ... "Automatic" that there is no dialog, just click the mouse you can blame me ... you ... oh.
This section mainly talk about the adjustment of image contrast of the two commands: Curves (curve adjustment), and Brightness / Contrast (Brightness / Contrast) command ... ...
Now, go look together?
Curves (curve adjustment) command
In the "Adjust" menu, select "Curves (curve adjustment)" command, adjusting the Curves dialog box that Figure 8 in that dialog then:
(Figure 8)
We look a little theory, and then use an image to demonstrate results.
First of all, Channel (option column).
And "Levels (Levels)" the same channel can be selected here, use the same. I do not speak out of turn up.
Then, the right button.
Or the same (just more than a "Smooth Smooth" button, and his role is mandatory to make the curve smoothing), the same methods. I do not speak out of turn up.
(Ah, but also all the same? Is not spanking it?)
(No! Not! Of course, different place, Let me show thin Road to ... ...)
Then, a curve.
Open dialog box, the curve of the curve at the default of "line" state.
Curve with the horizontal axis and vertical axis, horizontal axis represents the brightness value of the original image, the equivalent of the Input Levels Levels item; the vertical axis represents the new brightness value, equivalent to the Output Levels Levels dialog box items.
The horizontal axis and vertical axis can be adjusted by the relationship between the diagonal (curve) to control:
1, curve the upper right corner of the endpoint to the left to increase the contrast of the image bright areas, making the image brighter (endpoint moves down, the opposite results). The lower left corner of the endpoint curve rightward, increasing the contrast of shadow images, the image is darkened (endpoint upward, the opposite results).
2, using the "adjustment point" control the middle part of the diagonal (the curve with the mouse click, you can increase the node). Curve slope is his gray factor, if the midpoint in the curve adjustment to add a point to move, make the image brighter. Move the adjustment point, it will make the image darker (actually gray curve adjustment coefficient, this and the Levels dialog box drag the lower right triangle in the gray gray color scale, left-drag the gray color to improve the same order). In addition, Input and Output can also be numerical box control
3, if you want to adjust the image of middle tone, and do not want to adjust the image when the impact of light and shadow effects of the Department, must first use the mouse in the curve of 1 / 4 and 3 / 4 point increase in regulation, then transferred to the middle adjustment.
Also, if you want to know the image pixel value in a particular region, you can first select a color channel, the mouse on the image to adjust the part of the move the mouse slightly, then curves in a circle will appear (circle is Curves dialog box, the mouse is located in the region in the corresponding position), and Input and Output Value box displays the map area where the pixel value of the mouse.
3, drawn curve
Curve of a pencil lower right of the chart options, select him, and in any curve chart drag the mouse, you can draw an arbitrary curve.
When the mouse over curve of the chart will become a pencil icon, press the Shift key while clicking in the chart, the line is forced into a straight line constraint.
Now, we open a gray image, respectively, he converted to RGB and CMYK color mode the image to see in two modes, Curves dialog box, the difference between ... ...
(Figure 9)
Figure 9 is the case in RGB mode (RGB is the default setting), then the curve shows the brightness values range from 0 to 255, the representative image of the shadow left (the leftmost value is 0, that is black), right on behalf of image of the bright part (the rightmost value of 255, or white). Curve is equivalent to coordinate the back of the box, each box stands for 64 pixels.
(Figure 10)
In CMYK mode, the dialog box that looks like Figure 10 friends. At this time, "curve" range 0 ~ 100% (percentage), the representative image of the left curve of the bright part (left-most value is 0), the curve of the representative image of the shadow on the right (the rightmost value of 100%). Then each square is 25%.
In Figure 9 and Figure 10, Input and Output no value box. Once the mouse over graphs, the value will be shown matter, slightly adjust the curve, "input box" will appear.
If you use the mouse to click the black and white gradient bar chart below the double-triangle small icons, bright areas and dark location of the Department of exchange. Hold down the Alt key while you click the curve chart in the box, the box will become more refined, again click will restore the original size of the grid.
Finally, the "curve adjustment method."
In fact, the method is simple, just need to click on the curve with the mouse, drag on it ... ...
Click the mouse in the curve, an adjustment will increase the points (up to 14 adjustment points). Drag adjustment point, you can adjust the color of the image. Regulation point pulled out a chart or select a regulatory point and press the Delete key to remove the adjustment points can be.
Drag curve endpoint or regulation point, until the image is satisfactory so far. Must remember to Privew (preview) option selected, or you may not see changes in image Oh.
Now, we just wish to mention a gray image with the Curves command to see amazing results ... ... (Figure 11 is the effect before adjustment, Figure 12 is the adjusted results)
(Figure 11) (Figure 12)
OK! Curves command on the right is almost here. Next ... ...
Brightness / Contrast (Brightness / Contrast) command.
Brightness / Contrast command, and the first few commands, like: mainly used for adjusting image brightness and contrast. Use it on a simple image of the tonal range adjustment.
In the Image menu, select Brightness / Contrast command, can recall Brightness / Contrast dialog box, and shown in Figure 13.
(Figure 13)
Triangle slider to see the dialog box yet? Drag it can adjust the Brightness (brightness) and Contrast (contrast): the left drag, the image brightness and contrast reduced drag to the right, then the brightness and contrast increased (the value of each slide showed that the brightness or contrast value, the range of -100 to 100), after adjusting to the right, "OK" OK.
Now, we run in Figure 12, the command to see the effect of this order: (Figure 14, note the difference with Figure 12)
(Figure 14)
You satisfied with it? However, there are a lot of annoying his limitations: he role of all the pixels in the image (not for selective processing, can not act on a single channel), and not suitable for high output. But since it exists, naturally has his use, is not it?
Well, to look behind the stuff?
[Next]
Typically, to accurately identify the image "color cast", "not enough color saturation" and other color issues, it must be more accurate in the case of color, naturally, the first premise is the image of the "color correction" friends.
In the beginning of this post, I adjusted to the various commands Photoshop5.5 classified - into three categories: one for the adjustment of "contrast", one for the adjustment of "color balance", one for the "Edit Color" - front that are relevant to adjust the contrast of the order, this section focuses on adjusting the image on the "color balance" that is "color correction" of the two commands ... ...
These two commands are very simple to use, do not believe? Take a look!
Color Balance (Color Balance) command
In the Image menu select Adjust sub-menu in the Color Balance command, the Color Balance dialog box on the adjustable. (Figure 15)
(Figure 15)
Color Balance command to a general color correction, he can change the image color composition, but can not precisely control the individual color components (color channels), can only act on the composite color channel.
First need of the dialog box Tone Balance (balance area) options bar, choose the color you want to re-scope changes, including: Shadows (darkened area), Midtones (middle tone area), Highights (high-light area).
Options bar below the Preserve Luminosity (to maintain brightness) option to keep the image in the color balance. Usually, adjusting the RGB color model image, the brightness of the image in order to maintain the value of this option must be selected.
Then Color Banlance bar, which is the main part of the Color Balance dialog box: "color correction" on the box through the input numerical value here or move the slider to achieve triangulation. Triangle slider to the need to increase the color, or off the want to reduce the color, you can change the color of the image composition (increase in the slider close to the color from the color reduction), at the same time, Color Levels ( color section) box next to the three data values will be changing between -100 and 100 (a corresponding value, the three numerical boxes represent R, G, B channels of the color change, if the Lab color mode, These three values represent the color channel A and B). Adjusted to the satisfaction of color, according to OK OK on the line.
