How to Take Photograph Under Low Light Environment - Technology - Electronics

Some photos pursuit of the majestic and magnificent momentum, some of the photos in the pursuit of the most influential real detail, while low-light shooting out the photos often have a sense of intimacy. Low-light environments (bars, coffee shops, indoor natural light, the evening streets) is often the sunlight and shade, lights blurred and difficult to focus, be difficult to guarantee quality, the expression is difficult to seize, for many portrait photographers, full of charm and challenge, a test for our shoot photos with intimacy. When poor light, we must have the courage to go to photography, to look for interesting light and then thinking about how to use light, an interesting photo shoot. At the same time, the surface of portrait shots in low light often can not float on things and explore its shadow, can show the performance of other photographic methods.

1 to find the lightLess uniform distribution of light in low light conditions portraits need a good performance of facial expression, demeanor, therefore, suitable for smooth light or sidelight, the characters face have relatively abundant light, and asked the model to keep in the shooting not move. If conditions permit, you can use the reflector to fill light to the face, people like the effect is more prominent.

2 balance of light and shadeThe problem does not lie in the dim light of the entire photo, but that some parts of the scene is very bright and some very dark place. Light and dark is not the camera can control good, so from the beginning, you will be trained to identify the location of light evenly distributed, so the photo shoot will be full and rich.

Using a large aperture of the lens"Big" means aperture, such as f / 2 or f / 4. The larger the aperture, the greater the amount of light. In addition, the shallow depth of field, low light to capture clear photos is indeed more difficult. As the best to use the f / 2 lens. Most of the lens aperture transferred f/2.8 to shoot a good visual effects, depth of field sufficient image. Most of the zoom lens when shooting in wide-angle aperture can be adjusted to f/2.8 in the shooting of the vision can adjust to the f/4.5 does not apply to shooting in limited light conditions, and that is why professional photographers will spend millions to buy The aperture can be stabilized in the f/2.8 zoom lens.

Consider using a fixed focus lensFixed focus lens is fixed focal length lens, such as the 24mm f/2.8 lens or the 50mm f/1.8 lens. This lens is often the aperture is relatively large, so still better shooting in low light conditions.

(5) to increase the sensitivityOne can increase the sensitivity of the camera is absolutely double the efficiency of the photographer. Today, many cameras can be sensitivity transferred to 3200 and the image works well. Sensitivity prone to some noise, but it does not matter, a good photo will always be some noise. Note: The photo shoot in high ISO settings, if increased by the late, dark noise to affect the picture quality, so the appropriate application.

(6) Manual FocusPortraits typically use the central focus single point of focus, and focus for the model's eyes, and then press the shutter halfway and hold re-composition. Under low light conditions, sometimes the focus can not be out of focus because the subject is too dim, the contrast is too weak. At this time, the bg-e5 need to use manual focus lens that has a full-time manual functions at any time to manually adjust.

7 accurate meteringLow light conditions the camera set to spot metering. Approached the models, the region of uniform character's face light to fill the viewfinder, press the shutter measured by a set of aperture and shutter combination. Then the shooting mode is set to manual mode (M), set the aperture and shutter values in accordance with the previously measured parameters, so that you can ensure that the characters face exposure accurate.

Eight. Fell in love with a fuzzy imageIf other film does not come out, then had to accept that ghosting. Ghosting means move, move often become Smart for a photo. Think vibrant Rio de Janeiro carnival, dancing with the subject so that the screen is dynamic. You may ask, why not use a tripod? Tripod is very useful when shooting city night scene, but real life is fleeting, for the convenience of your shot and still down, so use a tripod will delay your time.

British photographer Harry Benson, in the past 50 years has been the record of the sign of the times, the Kennedy assassination in 1963, the Beatles U.S. debut in 1964, a portrait of each U.S. president since Eisenhower. Various experiences of Harry Benson, brings a wealth of shooting experience and knowledge, in low light conditions to shoot good photos, he also unique insights.

Q: In low light conditions, you have encountered the most difficult shooting conditions?A: The Kennedy assassination, I still will think of that scene, people screaming, the whole situation was chaotic, and completely unable to control, almost no light li-40b, but you do not have the opportunity to use the flash. Eventually people see that picture indeed real show was chaotic, crazy scene. Sometimes I would think, if you have a digital camera, if I can photograph better.

Q: you get used to the camera settings?A: aperture priority and manual, I would not use a high sensitivity, up to over 1000, of course, except in exceptional circumstances.

Q: Do you use auto focus or manual focus?A: It depends. If it is in low light conditions, manual focus may be unreliable, because to wait very long before the last coke. When I first started taking pictures, the camera ranging system, so have to estimate the focus, I am very good at doing this. Sometimes I will use auto focus, but if shooting important scenes or characters, or select manual focus. nb-3l

Q: If you want to use in low light flash, do you have any suggestions?A: I do not like to use flash, because it may be overshadowed by photos of the original elements, reducing the appeal of the photo. Natural dark light, the photos will show a unique texture. You can also try to model the background lights, creating a soft warm tone.

Q: For you, shoot film and digital What is the difference?A: Use the shooting of the film, the final outcome uncertain. In low light, the photo shoot is complete, I will be out of the sample, and then decide to force rushed a few files. In general, I would rush out about eight photographs, from which to judge the pros and cons. The digital advantage is that you can to deepen the ideas, rather than dwell too much on technical details.

Q: Give us one of your suggestions on how to?A: Do not be afraid, your casio np-20 photos will give you a surprise. Have a light to make sure you shoot the characters face, and then let go to shoot it. Processing capabilities of digital cameras low light I was very impressed, it can even capture you can not see the field.
