Digital Camera Selection and Application (4)

The biggest disadvantage of this machine is that it does not have manual control, white balance automatic control, exposure automatic control, but it has fixed-point metering and 7 exposure compensation, to a certain extent, to meet the need for manual control exposure, in fact, the 1400 maximum is also the author has been What's more, the aperture is out of control. Actually, it's a file, 5.6 for wide-angle, and 7.8 for telephoto. It changes with focal length and cannot control the depth of field.
The picture quality of the OLYMPUS C-1400L has always been the best word in the industry, and the quality of the picture can always be topped out in various evaluations. This is thanks to the high-quality lenses that even manufacturers are confident. If I don’t talk about various descriptions, I’ll use what I’m using: I use it to take wedding photos in the studio, use EPSON PHOTO EX to print on photo special paper, print to A4 size, after cold lamination, no customers think it The quality is worse than the photo, but I think it is worse than the photo, but this gap is not noticeable to the average user. OLYMPUS C-1400L battery life is very long, I use 4 domestic nickel-metal hydride batteries 1200mA 4 5, with 8M flash memory card, in standard mode, each with a flash can shoot 100 consecutive. With the high-quality mode (24 cards can be stored on the 8M flash memory card), 80 shots can be taken continuously without inputting the flash, and input into the computer.
OLYMPUS C-1000L: The appearance is exactly the same as that of its big brother 1400L, except that the “skin color” is slightly lighter. The 1/2 inch 810,000-pixel CCD is used. The lens is equivalent to the 35-mm camera 50-150mm, and the rest is the same as the 1400L.
Third, the application of digital cameras in the semi-professional field Digital cameras are not much different from the traditional camera when shooting, here's just a few things that are worth noting in the semi-professional field:
1, the use of light familiar with the traditional camera friends will surely find there is a very important indicator, digital cameras are not mentioned even mention: that is the speed of the flash synchronization shutter speed, like a fool camera, although with a flash, but in semi-professional The field also needs to consider when working with an external flash. Electronic flash is the most commonly used photographic light. Especially for indoor photography, electronic flashes with a size of more than 3 inches are often used. The external electronic flash relies on the light sensor on the electronic flash to sense the flash of the electronic flash connected to the camera and then flashes itself. The ordinary electronic flash process will take about 1/60th of a second, so it is a camera with a flash synchro shutter speed of 1/125 sec. The exposure time will be adjusted within 1/60th of a second to ensure that all external flash Synchro sensitive. This is a terrible digital camera! Of course, very few digital cameras that can adjust the shutter can be spared. Most digital cameras cannot synchronize with the external electronic flash. The reason is that the shutter is too fast. It is a digital camera with an external electronic flash connector. If there is no shutter adjustment, only Synchronized with the electronic flash connected to it, it is difficult to synchronize with other electronic flashes. There are two reasons for this phenomenon: 1, most digital cameras rely on the shutter to adjust the exposure, and do not show the shutter value. At this point the photographer cannot guarantee that the shutter is within 1/60th of a second. 2, most digital cameras flash sync shutter speed in more than 1/125 seconds (this is the author after many tests found). I can't synchronize with an external electronic flash many times with the OLYMPUS C-1400L test. Is there a solution? Of course there is, but it will take a lot of money. The most thorough method is to use a halogen quartz lamp (color temperature 3200K, different from the electronic flash, the effect is different, as will be mentioned later) without using an electronic flash, and usually use at least two for each 1000W. The halogen quartz lamp is always on when shooting, there is no problem with the speed of the flash synchronization shutter, and the shooting effect is clearly visible on the spot. The halogen quartz lamps produced in Shanghai are about 650 yuan each, plus softboxes or reflectors, and tripods, each of which is worth about 1,000 yuan. Of course, we must also consider the power supply status of the studio. Three halogen quartz lamps are turned on at the same time. The large power consumption and high fever is not a joke. In winter, it is impossible to use the air conditioning in summer. Method two: There is a ring-shaped high-speed flash tube, according to the introduction of flash synchronization up to 1/500 seconds, the basic can be synchronized with a digital camera, but there is still the problem of the flash synchronization shutter speed, so be sure to use your digital camera on the spot test It can be bought before, and the price is the same as the halogen quartz lamp.
2. Adjusting the color temperature The friends who are familiar with traditional photography know that the color film has the daylight type and the light type. The purpose is to apply to different light source environments. The daylight color greenhouse 5000K, the halogen quartz lamp color temperature is 3200K. Digital cameras can't replace film, so they use white balance adjustment, manual and automatic at the same time, manual adjustment has the flexibility, can create unexpected artistic effects, but manual adjustment is not so simple, it is difficult to grasp. Automatic adjustment can ensure that the shooting effect will not be greatly biased, but it is difficult to create special artistic effects, such as using the daylight film shooting, using a 3200K quartz light as a light source, you can create a warm atmosphere, the color yellow red, is Now wedding photography is a common practice, but shooting with a digital camera, using white balance automatic adjustment, the effect of shooting is not as obvious as the traditional camera, but the effect is also very good. There are also the same lights, the same model position, the results of the results taken with different color backgrounds will be different models of skin color. Different digital cameras make a great difference, so for the white balance adjustment photographer must be based on different photographic environments, different digital cameras to test their own, find out, have a good idea.
Regarding the digital camera here, even if it's finished, it's time to talk a little bit about the issue of printed photos. Digital cameras ultimately rely on printers to complete the entire process. At present, photo-level printers may use only a small number of sublimators. Color inkjet accounts for the vast majority, and the author is also a family of inkjet printers. EPSON Photo series is the first choice for photo print quality. The preferred photo quality glossy paper and photo paper for printing paper, and the print quality and general ink jet paper are simply different. There are 1440dpi and 720dpi resolution print quality can still be easily identified by the naked eye, we can see that the difference in print quality is not insignificant written in some articles, if the quality should still use 1440dpi print, the price paid is Longer print time and more ink consumption...
