Is it necessary to buy a light meter after buying a digital SLR camera?

Friends, for ordinary (ordinary) photography enthusiasts, because digital SLR cameras are equipped with multiple light metering methods, the photos taken are only used for travel, entertainment, souvenirs, data archiving, etc. , the exposure standards for photos are not high. Therefore, there is no need to configure an additional light meter. But for photographers engaged in professional (commercial) creation, relying solely on the metering in a SLR digital camera is far from enough, and cannot meet their rigorous and accurate metering requirements for the creation of photographic works. Because, due to the influence of different occasions or special scenes, the in-camera metering sometimes "lies in reporting military information" and draws erroneous metering conclusions, resulting in photos that are "overexposed" or "underexposed" and the exposure of the photos is inaccurate. Therefore, these professional photographers need to equip themselves with professional light meters that measure accurate light. For example, in situations such as still life photography and portrait photography that require extremely high metering requirements, you must use a professional light meter to accurately meter the light in multiple places, and then perform accurate exposure after calculation to make the photographic work lifelike and like the real thing. Fresh. This is why most of the photographer's works are done by manual exposure. How can it be done without a professional light meter.

Professional light meters are divided into incident, reflective, and flash types. The built-in light metering of current digital SLR cameras all uses reflective metering, and the metering results are satisfactory in most cases. However, for some subjects that require high texture, such as portraits, still lifes, snow scenes, ice sculptures, etc., using an incident light meter is more accurate and reliable than using a reflective meter. Whether the in-camera metering method is sufficient or not varies from person to person. It may be enough for ordinary photographers, but for professional photographers, faced with ever-changing light and changes and differences in people, In-camera metering alone is not enough. Although in-camera light metering is now much more advanced than before, compared with professional light meters, there is still a big difference in light metering methods and accuracy, let alone how much better in-camera light metering is than professional light meters. , this is a kind of offset frequency understanding. SEKONIC recently announced its light meter DIGITALMASTER L-758D, which is specially developed and designed for digital cameras, and DIGITALMASTER L-758CINE, which has a video shooting function. It is reported that these two products will be officially launched on October 25 and November 27 respectively, and their prices are approximately RMB 4,900 and 6,100 yuan. If professional light meters are no longer as good as in-camera light metering, then why does the world-famous Shiguang Company continue to produce professional light meters for professionals to use? Photography creation is an art, and it requires continuous improvement of technology to ensure it. When taking photos, you can use your past experience to estimate exposure, but this is just a general situation. You still have to rely on various sophisticated equipment when creating. The importance of "excellent weapons" can be seen from the grade of equipment used by various professional photographers. Otherwise, the products of famous companies such as Hasselblad, Chase, and Leica would not be astronomically expensive and used by professional photography experts. . In fact, after saying so much, the original intention is to have an objective and realistic understanding of a professional light meter, not to necessarily own it.
