Effects Is another year of flowers fall, is one year old flowers open (hehe, first sigh). This example is done by programming the mask element and using color techniques to achieve a "matte" effect, as shown in the effect picture. This effect is most worthy of the reader to learn how to use a simple program to create a certain speed of the components. This is another reason why this simple example has some charm. Demo Effect: (you can see the animation effect with the mouse movement) Click her
First you need to understand ~ Why is there a depth of field? After the fast rolling process has not been followed In fact, the aperture of the opening head is at the maximum aperture. In this way, the incoming light volume of the camera is larger than that of the camera. The warning window is brighter than the warning window. For the focus Structure But because it is the maximum
/object distance. Increase the focal length of the lens, enlarge the magnification, you can narrow the vision, the scope of the picture is small, the details of the vision to see more clearly; if you reduce the focal length of the lens, the magnification is reduced, the scope of the picture is enlarged and the scene is larger.The main parameters of the lensField angle: In engineering practice, we often use the horizontal angle of view to reflect the scope of the picture shot. The larger the foca
value of the 40-wire/millimeter MTF to 0.73 and 0.72, respectively. This means that the two lenses are used to take the necessary shockproof measures. During f8, The 35mm camera can take the best image that can be enlarged to a 24-inch image. At maximum aperture, the optimal lens can be assigned to the Leica M50/2 header, and its MTF focuses on an average of 0.50.Among all the large aperture portraits, Pen
1. Use the manual mode (we recommend the video "Wu Shitong photography basics 07-exposure compensation and manual mode")Before you start shooting, make sure that the settings of the fuselage are correct. Let's start with the shooting mode. No matter which shooting mode you usually use, in the field of low light motion photography, you need to use a shooting mode that gives you more room for adjustment. Manual mode (M files) gives you more control over the body, so using this mode f
To the photography enthusiasts to share a detailed analysis of the Canon 5DMarkII to the depth of the subject to more effectively focus on the shooting tutorial. Tutorial Sharing: Zoom in to show the Red box section. Aperture value in the F4, the depth of the screen did not get the focus, there was a virtual.

rotate it to a certain angle. Add a circle and ellipse to a certain portion of the stack, select the circles and then hold down the shift selection ellipse, and then select the Format tab to merge the cut in the shape. Sets the fill of the merged shape to a linear gradient fill, two gradient stops, all white, the transparency on the left is 84%, the transparency on the right is 100%, the angle is 1000, and no lines (Figure 3).

has a wide perspective and a short range of recent features, It also serves as a useful macro-head function when paired with a high pixel model. Second, fixed-focus high quality 35mm out of the noble Fixed focus lenses used, use zoom do not have too big obstacles, but the habit of using the zoom after the fixed focus is not necessarily used, because in addition to the difference between the focal segment, fixed focus lens quality and large aperture
questions: 1. Can your naked eye distinguish between barrel and pillow distortion; 2. Can you tell the differences between the 256 colors, 16 bits, and 32 bits on the laptop screen by the naked eye; 3. Whether your eyes can accurately detect spot and flare on the photos; 4. Can your naked eye distinguish the out-of-focal bilinear and non-circular dispersion circles; 5. Do you understand the four points mentioned above and use the SLR camera correctly. If the answer is no, this option is simple.

higher, and the weight of the lens itself is not guaranteed. The use of more resin lenses on consumer digital cameras, which is thin and light, is relatively easy to make, and as the process continues to improve, the lens of the resin lens is already comparable to the lens of the glass lens in terms of image quality.Aperture This concept is somewhat difficult to understand, summed up is to use the aperture blade to control the intensity of the light
I. Sunny 16 Rule) The "Sunshine sixteen law" is a method to correctly estimate the exposure values in sunlight when no metering table is available. Therefore, this law is applicable only when there is plenty of sunlight. Set the aperture to F/16, and the shutter is synchronized with ISO, or a little faster. For example, when ISO is set to 100, the shutter should be set to 1/100 seconds (1/125 seconds ). Therefore, the F/22
. The quantization error is shown in the following figure: Calculation formula of signal-to-noise ratio caused by quantization error: 3.2. Thermal noise Thermal noise is an inherent noise of the chip, caused by sampling buffer noise, sampling switching impedance, etc., is a fixed value, the general ADC will give the signal-to-noise ratio of the thermal noise. If not given, it can be calculated using the following formula: Nsd:noise spectral density or noise floordensity 3.3. Jitter Noise Jitt
From a photography perspective, correct exposure depends on many different factors. Some of them are what we usually know and can be confirmed in advance. However, if there are other factors, you must use an appropriate metering table. For example, the film speed, the maximum aperture of the lens, the available shutter speed, and the aperture range are all known factors. Unknown factors are the illuminati

By taking the natural light from the window, you can consciously zoom in and take the human shadows that are reflected in the glass into the screen to improve th
The 16 rule of sunshine. This basic law applies to scenarios where bright and even lighting is taken during the day, that is, when the aperture is F16 and the shutter speed is the reciprocal of the sensitivity index, such as the aperture F16 and the sensitivity is Iso100, shutter speed can be set to 1/100 seconds. On this basis, the aperture can be reduced to f22
