Canon camera shoots jewelry
Canon cameras could be used for jewelry photography. Here are some key points when shooting jewelry: 1. ** Choice of lens **: The macro lens is the first choice, such as the EF100mm f/2.8L Macro IS USM or the RF100mm f/2.8L Macro IS USM, which can capture the details of the jewelry well and highlight the designer's creativity. 2. ** camera settings **: - ** Aperture **: In order to focus more images, you can use a small aperture, such as f/22 to achieve a deep depth of field. - ** Shutter Speed **: Usually set to 1/100. - ** Iso-level: Can be set to 100. - ** Mount a tripod **: This is very important to avoid blurring the photo due to shaking hands. 3. ** Lighting **: - ** Dealing with reflection **: The studio environment should be dark. Control the lighting to adjust the degree of light reflection. A diffusing device could be used to reduce the reflection on the metal surface, and the reflective plate could be placed closer to the subject to make the light softer. The white reflective plate could reflect light back to the jewelry and hide the surrounding objects. The black reflective plate could eliminate the reflection on the flat gold jewelry. - ** Focus on the noble angle of the jewelry **: It is important to observe every corner of the jewelry before shooting. The effect of the diamond is different from different angles. When drawing the lighting plan, you must pay attention to each part of the jewelry. For black gemstone images, you can use multiple light sources to create layering, and use a mask on a lamp to create a striped lighting pattern to increase the attractiveness. - ** Light distribution for jade photography (refer to similar principles)**: Jade is a translucent material, and its light distribution needs to consider the water head (penetrability) and polishing process. Water head (penetrability) can be expressed by backlighting and one-way linear light; polishing process (smoothness) can be expressed by side light and bright spot reflection. To preserve details, soft light box or sulfuric acid paper can be used; the expression method of both water head and polishing process is to use high-light spots to make the material smooth and reflective, and use local linear strong light to express water head penetrability. There was no fixed rule for light distribution, and the light source had to be flexibly adjusted according to the quality. 4. ** Color precision and restoration **: If you use the Divine Bull flash (output color temperature is 5300K), you can adjust the camera's color temperature to 5300K to ensure that the color of the jewelry is true. You can also fine-tune it later. 5. ** Choice of background **: If it is jade, a light-colored background is not conducive to the reproduction of the outline and decorative patterns. It is better to use a darker background, such as dark gray, dark coffee, or dark green. 6. ** Method of composition **: Try to use the central composition or diagonal composition on the product composition to shoot. The camera and the product should be at a 45-degree angle to make the visual feel more comfortable. Read more exciting novels for free
Canon's new 100 micro lens shoots jewelry
Canon's new 100 micro lens can be used to shoot jewelry. From the jewelry photography case of a graphic designer, using Canon's new 100 micro lens and Canon 5D2 body could shoot jewelry photography films. Under the condition of only cutting and no other processing, good original film effects could be obtained. Even if the equipment was relatively simple (a few hundred yuan still life stage, 1000 yuan three flashes, a few hundred yuan light stand and tripod) and the photographer had not undergone formal photography training, he could still shoot good jewelry photography works. Canon's new 100 micro lens could better display the appearance of the jewelry itself when shooting jewelry. It used light and reflections to show the details of the jewelry, the craftsmanship, its own characteristics, and subtle defects and flaws, rather than relying entirely on post-production. Some features of Canon's new 100 micro lens were also helpful for jewelry shooting. For example, the minimum focusing distance of the RF100mm F2.8L Macro IS USM was 0.26m, which could shoot more detailed images. It had excellent image quality under the maximum aperture of f / 2.8, and it could maintain excellent standards from the center to the edge. Its 13 sets of 17 lenses and 9-blade aperture system could provide gorgeous background blurring and versatile detailed images in dim light. All of these helped to play a role in different jewelry shooting needs. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Nikon shoots jewelry
Nikon could use a variety of methods to photograph jewelry. For example, when shooting small objects (including jewelry), you could use two lights to light up, one with a harder light as the main light, and a soft light at an angle as an auxiliary light source. This would reduce shadows and prevent reflections from affecting the picture. You can also use the Nikon R1Ci close-up flash set, combined with the Nikon creative flash system, the wireless flash controller SU - 800, and the wireless remote control flash SSB-R200 to achieve wireless flash close-up. The flexible combination can remove shadows and highlight the main body through side illumination. For jewelry types such as rings that are more difficult to shoot, due to their small size, many reflective surfaces, and strong reflective light, you can use a fully enclosed light distribution. If you use a point light source to shoot, you will use more soft screens and lights. For example, you can use 4 flashes, 3 soft screens, 4 standard covers, and silver card paper.(The camera can be a Nikon D800, lens 105mm f2.8, aperture set to f25, shutter 1/100, USB 50, focal length 105mm, white balance 5200K). If you use natural light to shoot jewelry, the soft natural light on cloudy days is suitable for expressing the elegant style of jewelry. You can put the jewelry next to the window to shoot, which can reflect the rich layers of the jewelry surface and the picture is clean. If you use artificial light, you can set a multi-layer transparent plastic bag on the table lamp and flashlight (you can also use napkin or professional sulfuric acid paper) to create a soft light effect, and the light source area must be larger than the jewelry. If you want to express the luster of the jewelry, you can take a black-and-white photo to highlight the contrast between light and dark. You can also adjust the direction of the light. Use low-angle light, and use a flashlight or table lamp to illuminate from a distance to create a strong directional light. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What kind of lens looks good when the camera shoots jewelry and gold?
A macro lens was a good choice for shooting jewelry and gold, such as the EF100mm f/2.8L Macro IS USM or the RF100mm f/2.8L Macro IS USM. These macro lenses were able to capture the details of the jewelry very well and highlight the creativity of the designer. In addition, you can also use NiSi close-up lenses with conventional lenses such as 70 - 200mm and 24 - 105mm lenses to shoot jewelry and gold, which can also achieve good results. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The camera shoots black
If you use a camera to shoot black-related objects or scenes, the following are some points to note: * * 1. When shooting black objects (such as black pets)** 1. * * Focus ** - Because black objects could not provide enough reference for autofocus, they could not identify the appearance and expression through patterns like animals with flowers and colors, so they had to use light and shadow to assist in focusing. 2. * * Photometering ** - The automatic light measurement of the equipment might not be accurate. When shooting a black object with a dark background, the camera would automatically brighten the image to show more details in the dark area, causing the image to be overexposed, turning the black into gray. Therefore, he had to make good use of the exposure compensation function (following the white plus black reduction principle). 3. * * Light usage ** - If you shoot outdoors, try to shoot under the shadows of buildings or trees, or on cloudy days, in order to avoid strong direct light that causes overexposed highlights. - If you were shooting indoors, window light was a better natural light source, but you had to use a semi-translucent curtain to create soft light, and you could adjust the distance from the window to control the angle and brightness of the light. If the light in the room is too dark, don't forget to add a soft light cover or use a flashing light when using artificial light sources (such as LED lights or small hot shoe lights). * * 2. When shooting with a black background ** 1. * * Using props ** - Black curtains, black umbrellas, black cardboard, and so on could be used to create artificial backgrounds. If it was a planned shoot, prepare a black background cloth in advance and determine the size according to the subject. When shooting, keep the black background cloth at an appropriate distance from the subject to prevent the background details from being too clear and increasing the workload of post-editing. You can also use the lens 'characteristics to blur the background with a shallow depth of field (such as a large aperture or telephoto lens). 2. * * By adjusting the parameters and controlling the angle ** - Spot photography could be used to ensure that the subject's exposure was accurate. If the background itself was lower than the subject's brightness, the background light would become darker and weaker under the camera's optimization calculation. - He was good at making use of the angle of the environment and adjusting the shooting angle to the black background. It was easier to form a black background with the spot light measurement method. - When the background of the dark part was not dark enough, the exposure compensation parameters in the camera were used to reduce the brightness. 3. * * Using the calendering technique ** - Use a small aperture, a high-speed shutter, and a low USB (such as USB 100). At the same time, use a flash to complete the calendar. * * 3. When shooting a black object against a black background (both the object and the background are black)** 1. * * Backlight Operation ** - Add a backlight to the frame and create a visible outline at the edge of the object to separate it from the background. However, it is important to note that black will actively absorb light. It may require more light sources than usual to create a visible outline, and the color will turn gray in the area where the light shines on the object. In this scenario, the lights are set from the controller to avoid backlighting (unnecessary light can be cut off using cells or black marks that help focus the beam). 2. * * Cause brightness difference ** - Make the subject slightly brighter than the background to visually separate the subject from the background. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The camera shoots the propeller
If you were shooting the propeller in the aerial image, you had to control the flight speed when flying straight forward. It was not recommended to push the propeller forward at full speed (100%), and when the camera was at a horizontal angle, this operation could easily capture the propeller in the picture. If it was to shoot a ship's propeller, it might be equipped with a propeller protection cutter (pan knife). When the rope was close to the propeller, the rope would be driven by the propeller to the island mouth and then quickly cut by the blade. However, the reference materials did not mention any special precautions or techniques specifically for shooting ship propellers. When shooting the aircraft propeller in the air show, due to the fast speed of the aircraft, the instantaneous action, the high requirements for equipment, and the need for high-end body (such as focusing speed, continuous shooting speed, and small shutter lag, etc.), it may be necessary to mount a suitable lens such as a super-long focal lens or a zooming telephoto lens to shoot. However, there was also no mention of the special points for shooting the propeller. In addition, if the flight speed was too fast, the turning speed was too fast, or the pitch speed of the cloud platform was too fast, it was easy to cause problems (such as the propeller being damaged, the image being blurred, etc.). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Canon shoots commercial products
If it was used for commercial products, different focal lengths had different uses. In terms of fixed-focus lenses, the RF16f/2.8 could be used for wide-angle shooting. It was of high quality and relatively cheap, about 2K. The RF35f/1.8 of the short-focus lens was a relatively standard human lens on a full-frame camera, and the price was basically around 4K. The medium-focus lens, RF85f/2, was more suitable for portrait shooting. It could also be used for close-up shots of some commercial products to obtain better blurring effects. The telephoto lens, RF100f/2.8, was very good for macro and close-up, but the price was around 10K. The RF135f/1.8 had good photo effects, obvious blurring, and a sense of atmosphere, but the price was around 15K. If the super telephoto lens was chosen to be fixed-focus, then an RF800f/11 could be considered. In terms of zoom lenses, Canon's 100 - 500mm f/4.5 - 7.1L IS USM ultra-long focal length zoom lens (Canon's radio frequency mount) could also be used for a variety of distance shooting needs in commercial products. Canon's 50 - 1000 super large zoom lens could also be used for commercial products. However, the specific choice still needed to be decided according to the actual shooting scene, budget, and the requirements for image quality and blurring effects. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The TV camera shoots the moon
Here are some of the key points of the moon shot by television cameras: 1. ** Scene Selection **: - In terms of focal length, it was best to choose a lens of 400 mm or more. If it could reach 800 mm or more, it would be more conducive to showing the details of the moon's surface. If the focal length was below 400mm, the moon would appear smaller in the picture. It could be improved by zooming in and trimming the picture or using a telephoto lens. A telephoto lens can better zoom in on the moon and capture its details because the moon is very far away from us. 2. ** Stabilizing Equipment **: - When shooting the moon, especially when using a telephoto lens, it was easy to shake when held. A tripod was needed to stabilize the camera. If there is a shutter release, you can use the shutter release to trigger the shutter. If there is no shutter release, you can use the timer function to shoot to avoid shaking when the shutter is pressed. 3. ** Shooting mode and parameters **: - In terms of mode, he could choose the M mode or aperture priority mode. The aperture was adjusted to between f6.3 and f16, and the shutter speed was chosen to be above 1/100 second. If the moon was exposed normally, the sensitivity would be set to 100. - In a dimly lit environment, one had to pay attention to the problem of overexposed. Because the actual brightness of the moon in the sky was high, too slow shutter speed would cause overexposed. At the same time, the moon was in motion, and too slow shutter speed would cause the moon to form a shadow in the picture. 4. ** Focus Method **: - Manual focus was a better choice. You could use the zooming function to focus or turn on the peak focus function to improve the clarity of the manual focus so that you could capture a clear moon. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The camera shoots the starry sky
Different cameras had different methods and precautions to take pictures of the starry sky: ** I. Use SIGMA-15mm F1.4 DG GN Diagonal Fisheye| Art lens shooting starry sky ** 1. ** The features and advantages of the camera ** - This was a fisheye lens with a 180-degree angle of view. It had high imaging quality and excellent control of the center and edge effects. Its aperture was F1.4 - F16, with 11 circular aperture blades. When shooting the starry sky, the large aperture F1.4 could allow more light to enter, and the image could be shot at an USB of 1600 without worrying about noise. For example, when taking a single shot of the starry sky, setting the focal length to 15mm (180 degree angle of view), aperture f1.4, Iso2000, and exposure time of 20 seconds would have a very good effect. Moreover, four photos could be stitched together to get a picture of the Milky Way arch bridge, which was easier to achieve than the 16 - 35mm lens. 2. ** Shooting Techniques and Problem Solvers ** - ** Depth-of-field control **: If you are worried that the maximum aperture of f1.4 will cause the depth of field of the picture to be too shallow and the ground to be blurred, you can keep the main subject further away from the lens to maintain the clear effect of the main subject and the background. - ** Focus problem **: Use the camera's zooming function to view the screen. Choose the brightest star, manually focus, and slowly adjust the star to the smallest spot on the screen. Since it was a screen shot, there would be no problem with the camera going out of focus. 3. ** Other features of the lens ** - The lens weighed 1360g, and its size were 104.0mm x 157.9mm (L mount) and 104.0mm x 159.9mm (E mount). It had a special lens ring design that could balance the weight, facilitate horizontal and vertical switching, and protect the lens. The lens structure consisted of 15 groups of 21 lenses, including 4 FLD and 3 SLD special low-dispersion glass lenses, as well as 2 aspheric lenses. The closest focusing distance was 38.5cm, and the maximum magnification was 1:16. The lens driving system was a high-speed linear motor, and the bayonet types were L and E. ** 2. Use SIMAR 14 - 24mm F2.8DG GN| Art lens shooting starry sky ** 1. ** Characteristics of the lens ** - This was a zoom lens. In order to obtain sufficient light, it had a large aspheric lens and an integrated hood ("light bulb" head). The overall size was relatively small and weighed only 795 grams. 2. ** Shooting operation example ** - It could be installed on a SonyA7M4 for shooting. ** 3. Use the iPhone to take a picture of the starry sky (using the original iPhone camera as an example)** 1. ** Porthole Shooting (suitable for shooting the starry sky outside the window on an airplane)** - He clicked on the small arrow above the shooting interface, clicked on the night scene mode button, and slid the progress bar to the right. The phone was close to the porthole. If it was blurry and could not be focused, click on the small flower icon in the lower left corner to manually turn off the macro function. After pressing the shutter, the exposure time was about 10 - 30 seconds. The color adjustment parameters of the starry sky after shooting: Color temperature-10, highlight +15, light sense +20, blue saturation in the HTL tool +3, filter: Liebilever. 2. ** Shooting in normal scenes (when no special scenes are mentioned)** - He turned on the camera and tapped on the half-moon icon (those who couldn't find the half-moon icon could find it by covering the camera). He stretched it to 30 seconds and zoomed in to take a picture. ** 4. Universal Starry Sky Shooting Setting ** 1. ** Three Elements of Exposing ** - Aperture: A large aperture (such as f/1.4 to f/2.8) can increase the amount of light entering, but try not to open it to the maximum to avoid "aberrations" at the edge of the picture. - ** Shutter Speed **: It can be set according to the "500 rule", which is to divide 500 by the equivalent focal length of the lens to get the upper limit of the shutter speed. After this time, the stars may appear smeared, but this is only a reference. The specifics will be determined according to the actual shooting effect. - ** Iso-level **: The value should be maintained between 1600 and 3200. This range can ensure normal exposure and control the image noise within an acceptable range. 2. ** Other settings ** - ** White Balance **: Choose Manual. When there is no interference from artificial light sources, setting it at about 3000K will make the screen appear colder. If there is, you can set it higher to achieve the effect of alternating between cold and warm. - ** Focus **: Choose manual focus. You can adjust the lens focus ring to infinity (infinity) and then slightly turn it back. You can also use the camera's real-time view function to magnify the starlight in the picture in a dark environment for precise focus, or find a distant bright spot (such as a lighthouse or a bright star) to focus and lock the manual mode before shooting. - ** format **: Choose the RAW format to shoot. It has more room for adjustment than the JPEG format, which can effectively improve the image quality. - ** Anti-shake **: Since shooting in the starry sky requires the camera to be placed on a tripod for stable shooting, the anti-shake function on the lens should be turned off to prevent the camera from shaking slightly and blurring the picture. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The camera shoots the electronic screen and flashes
The main reason why the electronic screen flashed when the camera was shooting was because the screen refresh rate was not synchronized with the frame rate of the camera. Here are some solutions: 1. ** Adjusting the frame rate **: For old-fashioned televisions (with a frame rate of 50), you can set the camera frame rate to 25 or 50 frames to eliminate flickering. For the problem of flickering on the LED screen, you can try to set the frame rate to 50 or 60 frames per second to reduce the screen flicker. When shooting different scenes, you can adjust the appropriate frame rate according to the actual picture. For example, when shooting scenes with different frame rate screens, you can adjust the frame rate separately to avoid flashing. 2. ** Shutter speed adjustment **: Flicker is caused by the shutter speed not matching the light frequency. You can adjust the camera's "Electronic Shutter" option, such as lowering the camera's shutter (30 is the best value) in Shutter priority mode, and adjusting the sensitivity of the camera to maximize the overall brightness of the shot (reduce the sensitivity of the camera). You can also set the shutter to an integral multiple of the stroboscopic period. 3. ** Adjusting shooting angle or focus **: Change the angle of the camera to reduce the flashing stripes as much as possible; click on the light source in the video recording interface of the mobile phone to focus the camera on the light source to reduce the flickering phenomenon when shooting the video. 4. ** Using auxiliary equipment **: You can buy a prismatic lens and install it in front of the lens, or attach a prismatic screen film to the screen, but the brightness of the screen will be dimmed. 5. ** Adjusting the parameters related to the monitor **: You can change the monitor or use different dimming technology (such as the LED back light with the DC-dimming method) to avoid the flicker. You can also adjust the brightness, contrast, and other parameters of the monitor to eliminate the flicker problem. 6. ** For special equipment **: For example, the special camera for the LED screen of the World Friend was specially developed for the situation where the scanning display was not synchronized. It suppressed the camera's sensitivity adaptation and the image information that was not synchronized, effectively eliminating the flashing and rolling phenomenon of the image. However, it had to be customized according to the object of the shot. For example, the appropriate lens mm number was determined according to the on-site installation distance to ensure that the proportion of the captured LED screen was more than 2/3. When it was customized, it had to be specially focused and produced according to the shooting distance of the camera. It was only suitable for shooting with a large LED screen or LED digital tube, and was not suitable for shooting in a conventional environment. In addition, check whether the video head is abnormal, such as whether there is any loose, virtual connection, or damage to the video head. Use a step-by-step inspection method. You can start from the video head on the camera side or check from the monitor side. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The camera shoots the reflection on the metal surface
When the camera shoots reflections on metal surfaces, the following methods can be used to reduce or eliminate reflections: - ** Using a Polarizing Mirror **: A Polarizing Mirror is also called a Polarizing Mirror, or a PL Mirror for short. It is a type of filter. By installing it in front of the lens, adjusting the shooting angle and rotating it, one could see that the reflection would be weakened or even eliminated. However, it should be noted that the crystallizer is mainly used to eliminate or reduce the strong reflection of non-metallic surfaces, but it also has a certain weakening effect on the reflection of metal surfaces. - ** Use a special spray device **: This device can reduce the reflection of the metal surface. - ** Use background plate **: Use the background plate to reduce the reflection. - ** Light source adjustment **: Use a soft light source, such as a soft light, a soft box, etc. to evenly illuminate the entire scene to reduce excessive reflection; Use backlighting, which is to place the light source behind the camera so that the light shines on the object from behind; adjust the angle of the light source and the camera to find the best shooting angle to maximize the metallic luster effect; Pay attention to avoid too much light and adjust the exposure appropriately to maintain the details of the picture; avoid reflecting objects in the surrounding environment to affect the metallic luster effect, especially to prevent yourself from being photographed. - ** Reduce ambient light **: If the shooting environment is bright, appropriately reduce the overall environment lighting to reduce reflection. - ** Use a light-blocking cover **: As long as you don't shoot from a special angle, the light-blocking cover can basically eliminate reflection, and it's easy to store and carry. - ** Post-processing **: For example, the Oppo Find X8 series uses the industry's leading flagship camera and powerful NPu chip to achieve fast and efficient real-time reflection recognition and elimination. Its software algorithm is in-depth research from visual science, optical imaging, and other aspects to accurately capture reflection characteristics and target processing. However, this was dependent on the specific function of the mobile phone. After the camera was taken, it could also use a similar image post-processing software to reduce the reflection effect. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
