Make photograph cleaner and more transparent

In my opinion, the so-called "clean" or "transparent" means "not dirty or disorderly", canvas prints and I think the main influencing factors, including equipment, early composition, late color adjustment and picture details, are determined.


Although this is a relatively minor factor, it is still put forward.

With the specifications of the photographic equipment, canvas prints online australia there is no doubt that the more expensive the better, no matter how well with small spittoon is no match for the Outs, black card did better than the whole picture, not to mention the 8 x 10, and resolution, color difference, glare resistance, color trend, dynamic range, Ago Gann these factors will have an effect on the picture, in order to better the original performance and space, still want to try to choose better equipment.

Let me mention the filter here. The influence of filter lens on the cleanliness of the picture is very significant, and the defect and color deviation of poor quality filter lens on clarity cannot be ignored. Therefore, it is necessary to use as little as possible such as UV mirror and CPL mirror.

Second, the early

The early stage mainly includes composition and shooting.

1. The composition of a picture

Let's start with composition. Composition is the arrangement of elements in the picture. The composition of a good work must be simple and clear. If there is a lot of clutter or other irrelevant things in the composition, it will definitely lead to unclean. To take an extreme example, such still life works in the picture below will certainly not be unclean, except the main body is blank.

A good composition should allow the eye to focus on the main body. It can ensure the main body to stand out through the arrangement of objects, guiding lines, perspective, focal length and other composition methods.

Of course, you can also use some techniques, such as slow doors and silhouettes.

The effect of early shooting on the picture effect is also great.

The biggest impact may be the weather. For weather like cloudy day or haze, normal shooting will not have a good effect, but you can shoot from a different Angle. For example, slow door shooting on cloudy day and long focus shoots on haze weather.

It is also important to note that many of the viewing platforms are separated by a layer of dirty glass, which has a significant impact, and there is no good solution. As shown in the picture below, there are reflections and glare. The clarity is also reduced.

Three, toning

Toning has a lot to do with the early days, but to cut down on the length; it's all in the late stages. Toning can be divided into tone and tone.

1. The tone

In terms of image tone, the main cause of unclean is generally "grey". If there is a strong sense of haze, it is definitely not clean, just like a layer of grey.

The histogram can also be seen clearly, the pixels are stacked in the bright part, the contrast is small, and it will look very dirty.

The latter method is to increase the contrast. Note that this is about contrast, not simple contrast. In addition to directly improving the contrast, the contrast between the main and the secondary, the local, the color contrast, the contrast between different tones, the contrast under different tone, and so on. For example, conventional adjustments in landscape photography: lowering the highlights and increasing the shadows actually reduce the overall contrast, but enhance the contrast between the sky and the landscape. There are many tools for increasing contrast, such as directly increasing contrast, such as adjusting color levels, using curves, such as increasing clarity, such as subtracting and deepening, such as various plugging, and then re-applying all of the above methods in different selection areas. There's a lot of ways to do that. It should be noted that the contrast enhancement does not mean a large increase in contrast, which will make the picture too heavy and easy to see, such as the picture below.

In addition, improving the brightness of the picture, including over-exposure, can also effectively make the picture cleaner, which can create a lot of white space and make the picture more concise. The premise is that there is no problem with the composition and color of the picture itself, and over-exposure will not affect the expression of the picture. Of course, low-profile photos can also be very clean.

2. Color

Tonal respect is much more complex, say from hue, saturation, lightness a bit.

1) Color matching

Colour is tie-in first, also be colorific photograph collocation actually; this is a comparative core problem.

A) First of all, monochrome and black-and-white photos are easy to look clean because there is only one primary color and no interference. This can be controlled in the early stage or unified in the later stage. For example, the picture below is a cool, monochrome photo.

B) At the same time, similar to monochrome, and adjacent colors, will also achieve similar visual effects.

Both of the above are very safe color schemes or color schemes, which will give people a very comfortable experience, it is difficult to make problems, and can at least meet the need for cleanliness, although it may be monotonous.

C) and then complementary colors. In fact, this is a very common color scheme, but it is also often the cause of dirty pictures. Most people's color schemes may choose complementary colors or variations of complementary colors (e.g., color division, three roles).

As long as the complementary colors of the two pictures are basically concentrated in one area, both of them are ok, but the taboo is that the colors are intricately distributed. For example, in the picture below, yellow, red, green and blue all exist, and they are scattered and scattered. Is it not so clean? Of course, there are saturation and contrast issues.

2) Purity of color

The purity of the color also has a great influence on the picture. For example, if the blue is mixed with yellow, it will become neutral color, which will cause the color to grey and appear unclean. The principle is very simple. Pure blue is R=G=0, B>, and pure yellow is R=G>0, B=0. When the proportion is mixed together, it is equal to the mixture of grey and yellow or blue.

At this time, the channel curve or alternative colors can be used to eliminate the color, so as to make the eye color more pure. Choose a color, add adjacent color, reduce complement color, can make this color more thorough. Simply put, if you want to enhance blue, you need to add cyan and magenta, but less yellow. To enhance red, add yellow and magenta, reduce cyan.

Now let's talk about saturation and lightness, let's start with a color theory, PCCS 12 tones. PCCS, a color system developed in Japan, divides eye color into 12 tones according to the combination of saturation and lightness.


3) Saturation

As shown in the picture above, the simple way to make the picture clean is to reduce the saturation. High saturation will make the picture like oil painting, which is very boring. When the subject and other distinctions are not obvious, the uniform saturation also makes the picture look more comfortable. In the picture below, orange and blue are contrasting colors with similar saturation. Of course, this is under the premise that the saturation is not too high; otherwise there may be a very strong sense of oil painting.

4) Lightness

Lightness is relatively simple, the following are said to be the main color or main color. High brightness and low saturation can make a photo look fresh. And high brightness collocation is high saturation, can present bright-colored, full-bodied feeling. Low brightness and low saturation will present a more tranquil and quiet atmosphere. This is probably the case, of course, there will be a lot of counterexamples, specific case analysis, toning is not dead law.

Four, details

In fact, this is easy to say. First, the edges should be clear, that is, 2 Photo Collage on Canvas sharp enough. If you look at these two pictures, it is obvious which one is cleaner in detail. Therefore, in the early stage, we should ensure that there are not too many noise points, and in the later stage, we should not add particles randomly or sharpen excessively.
