Using Photoshop 4.0 and 5.0 Software to Experience the Application of Different Original Colors

First, before adjusting the picture, it is necessary to analyze the original thoroughly for classification and queuing


Second, based on proofing, printing gray balance test card as a basis, gray balance curve as one percent error


Third, the original color palette experience more than a dozen methods


Fourth, neutral gray proofing, printing tone reference value





Using the Image menu in Photoshop 4.0 5.0, you need to start with a variety of channels. Through continuous practical exercises, you will be able to operate quickly and successfully.


Before adjusting the picture, it is necessary to analyze the original thoroughly and categorize the queue;


The curve from white field to black field should be based on the results of proofing and printing gray balance test card test. In the picture adjustment, the gray balance curve needs to be 1% error-free.


Check the scanning error, use the apple M curve to correct the white field is balanced; C5M3Y3, whether the black field balance C96, M88, Y88, K75.


Check if the color of the picture is deviated, from neutral to neutral black.


In the Window menu, select show channels, open the black channel, analyze the tone of the black version, adjust the black tone using apple or apple M (short inks based on three primary colors, It's still long black tone with ink removed. According to the requirements of the original version of the black version of the original, adjust the length, the highest value of the black version is 75,85,95,100 range. (This is to be explained here: the black version plays an extremely important role in the picture. The black version is the skeleton, which is the support of the level and the spirit. The dark tone is handled improperly, making the picture dark and dark. Properly handled, hierarchical Obviously, the three-dimensional effect is strong.)


The manuscript that focuses on landscapes should be first layered. There are distinctive landscape manuscripts such as: Morning clouds, sunset clouds, rainbows, and backlighting photography should have an exaggerated atmosphere.


Manuscripts based on flowers, pay attention to the highlighting of the basic colors and the vividness of the saturation of the colors and the contrast of the layers (the ratio of the reverse colors and the effect of the K-board)


For manuscripts based on characters, try to use the M-curve to adjust the proportion of colors. If the dark field does not reach the gray balance, the selecitre color K can be used to compensate for the dark field gray balance. However, if the selection is not easy to use, it will appear. Dew phenomenon.


Use S-curve to adjust the dark manuscript which is thick and dark. This type of manuscript is mostly light-received. The foreground color is very light, and the depth of field is very dark. For example, the scene of an indoor meeting, because the flash index is not strong when shooting, or is affected by the spotlight brightness, Make the theme of the podium not clear.)


The manuscript with low contrast and high contrast is adjusted by increasing the steepness of the highlight curve. This manuscript has a large gray scale (about 10%, 10% increase to 3%), and the light receiving portion is brightened.


For boring manuscripts, use the Apple M curve to drop 5% from 75%, or drop a color curve field alone. When adjusting, balance must be achieved.


Use Color Balance color balance to make complementary adjustments to color-originated manuscripts; cyan, magenta, yellow, red, yellow, and violet. Adjustment value is within 15


Use the Apple V menu for hue, brightness, and saturation adjustments: Adjust the value within 5 digits.


Use the variance color change menu; you can adjust the color rich manuscripts, such as the morning glow and the rainbow, and then make exaggerated adjustments to make the color more pure, crisp, and thick.


With the Select Color menu: selective color gray can be very poor, there is no color manuscript adjustment, whenever you choose to gray balance adjustment close to gray, the figure is also rich in color. However, it should be used in combination with a variety of methods.


In the use of selective color selective color, can only be used as a compensation, adjust the value is not easy to excessive, or there will be color overshoot phenomenon, even if a large adjustment can only be done once from 0 to 100 adjustment (except for special documents).


In the process of adjusting the curve, even if you think that the picture is adjusted well, you can not ignore the balance of neutral gray with 25%, 50%, 75% for gray balance basis.
