Sigma dp flash enthusiasts absolutely benefit from playing flash.

Black technology camera Sigma dp is a portable digital camera. This camera is visually textured and suitable for flash lovers. It's simply welfare! The picture quality is guaranteed, and its mirror-to-mirror shutter design can better meet the craze of sweeping the street, which is absolutely amazing! Next, I will teach you how to play Sima dp!

The SLR we usually use is the focal plane shutter, and the synchronization speed of the flash is generally 1/200 s- 1/250 s. If it exceeds this speed, we need to use the high-speed synchronization function of the flash and flasher, but not all flash and flasher support high-speed synchronization. At present, among the flashlights on the market, the high-end flashlights of the original camera basically support this function, and the quality is relatively stable, but the price is high. Among the flashlights supporting high-speed synchronization produced by the vice factory, Yongnuo has high cost performance, but the quality is unstable. I remember when YN568ex came out as Yongnuo's first flash supporting high-speed synchronization function, I started with one, repaired it twice, and it has been left out in moistureproof box. Recently, PhottixMitros was tried, and its workmanship is comparable to that of the original factory. After several high-intensity (sun and rain) tests, there has been no mistake. In addition, the flash needs to support high-speed synchronization, and the flasher is no exception. If your lamp group is all original lamps, then directly consider the original flasher, which is stable and reliable and can give full play to all the performances of the lamps. However, the collocation of more players should be the combination of the original factory and the deputy factory to form a light group, which is economical and practical. At this time, a one-size-fits-all auxiliary factory flasher is needed. I used to be a user of Yongnuo 622c, and I was shocked several times in several commercial shooting. Nowadays, many wedding photographers are flashing with phottixodin, and the feedback is not bad. All right, back to the point. Generally speaking, if you want to play high-speed synchronous flash with SLR, you need to buy the lamp and flash supporting high-speed synchronous function in advance due to the limitation of shutter physical characteristics. This is not a small investment.

When I received Sigma dp camera, I couldn't wait to test its flash synchronization speed. With the inter-mirror shutter, parameters such as11250s and f/2.8 can be flashed easily. The flasher I use is Nikon's PhottixStrato II, and I also have Yongnuo 622 Nikon and Canon, Yongnuo RF-603 Nikon, king pro Nikon and Puwei plus iii. Among them, Yongnuo 622 Nikon can successfully flash, and Puwei is self-evident. As for the flash, there are basically no restrictions, and there is no need to consider TTL and other functions. Speaking of flash, my favorite is YN560iii. The price is cheap, it is easy to use manually, and it doesn't hurt when it is broken. It is more than enough to play high-speed synchronous flash with dp. Ok, speaking of which, let's welcome the camera protagonists in this evaluation-Sigma dp2, dp3! The main character of lighting-photototixmitros (more on the table than YN560iii)! Lead flasher-Puwei plus iii (better than most flashers on the market)! Debut!

I have mentioned high-speed synchronization so many times, so I won't go into details here. I searched a lot on the internet. Let's talk about the charm of high-speed flash. When you are outdoors in sunny weather, you want to pursue the beauty of large aperture and let the light fill the subject. At this time, you need high-speed synchronous flash memory! (Of course, there is another scheme to pursue this effect, that is, adding an ND lens to the lens. Excellent lenses are expensive and easy to consume, and need to be replaced regularly. ). For example, if you want to freeze the motion of an object and use a flash to fill the main body with light, the general synchronization speed is only1/200 s-1/250 s. In fact, it is difficult to freeze the motion solidly in this shutter interval, and it is inevitable that there will be virtual shadows. At this time, high-speed synchronous flash is needed!

First of all, let's feel the contrast between natural light and flash in outdoor portrait shooting.

1/60s, f/2.8, iso 100, dp3

Interested friends must find that this is not a high-speed flash portrait. Indeed, it was cloudy on the day of shooting, and the characters were under a large shade. In order to fully expose the environment, it is not necessary to open the shutter at high speed. The focal length of dp3 is 50mm, which is about 75mm when converted into 135 frames. It is very suitable for taking portraits of some people. This example is to let everyone feel the small charm of outdoor flash, which can make people jump out of the background completely and play a role in strengthening the subject.

First the appetizer, then the main course-a veritable high-speed synchronous flashing portrait. On a sunny afternoon, the scene light of 1/800s, f/2.8 exposure value was easily balanced with the flash as the main part and the sunshine as the auxiliary part. The maximum aperture of dp3 creates a beautiful blurred background, which makes the picture melt like cream from the focus to Jiao Wai, fresh and natural.

Comparing the following two photos, you will find obvious visual differences between high-speed synchronous flash and ordinary synchronous flash.

1/ 1250s，f/3.2，iso 100，dp2

1/ 125s，f/ 16，iso 100，dp2

The above picture uses high-speed synchronization, and the following picture darkens the environment by narrowing the aperture. In terms of flash power, the above picture uses a large aperture, so the flash does not have full power output. Because of the ultra-small aperture, the picture below requires ultra-high power to make the subject have normal brightness. For the flash, the aperture f/3.2 is easier to balance the field light than the aperture f/ 16. Under the high-speed synchronous flash, the blurring of billboards in the background restaurant is very helpful to the performance of the main body, and even the colors in the background have the finishing touch on the picture. On the contrary, in the following picture without high-speed synchronous flash, complex background information disturbs the whole picture, and the transition from light to dark of the face is also stiff and lacks aesthetic feeling.

After talking so much about the charm of high-speed synchronous flash, remember not to be too obsessed with it. In some scenes, I think the small aperture also has its own unique charm.

In addition to the outdoor portrait shooting mentioned above, the application of high-speed synchronous flash will also be used to shoot fixed-frame moving objects. This time, we will turn the outdoor to the indoor, shoot a red wine glass in the shed and freeze the shape of a drop of red wine.

1/640s，f/ 16，iso 100，dp3

Ok, let's imagine that if we use a focal plane SLR camera, we need to use the shutter speed of 1/640s to freeze the flowing liquid, and we need to use a flash to achieve high image quality. So first of all, we need more than one flash lamp that can support high-speed synchronization function to complete multi-lamp light distribution. In addition, we need several flash lamps that support high-speed synchronization function, and a macro lens is also essential. If you are just an ordinary player, isn't this threshold a bit high for you, making you flinch?

If you want to experience the fun of high-speed synchronous flash, but also take into account portability, upfront investment and cost performance, dp has more obvious advantages than ordinary SLR cameras. On Sigma dp series cameras, you can arbitrarily combine the exposure parameters. Theoretically, you can use any shutter speed to synchronize the flash (the synchronization speed of the flash will increase as the aperture shrinks). From ordinary to high speed, you don't need to use any function switch, and there is no special requirement for the flash and flash, as long as you can flash, you can play freely. A portable high-quality camera like dp, I value its playability more. A dp can not only record your life with you, but also become a flash weapon at any time. I really can't put it down.
