Photography skills of digital camera
With the popularity of digital, digital camera (DC) is no longer a rarity. Nowadays, digital photography puts forward new requirements for people on the basis of the original shooting skills. Many primary users report that the photos taken by digital cameras are dim, lack of vitality, more noise, scene depth (especially in macro mode) and color cast. But photography is a bridge between soul and light, so it is not easy to master the traditional shooting skills. Let me briefly talk about the problems that digital cameras must pay attention to in shooting, and also talk about some matters before and after shooting.
1, browse instructions
Many users don't like heavy and complicated product manuals, and generally like to explore for themselves after buying digital cameras. Of course, there will be some surprises in the process of groping, but it takes a lot of time, and you can't systematically understand the characteristics of your product in the shortest time; If you read the instructions before the operation, you can also avoid some wrong operations. Therefore, when you first come into contact with new products, you should first briefly browse the instructions compiled by the manufacturers for everyone and get familiar with the basic menus and functions of digital cameras. If you don't know anything in the future, you can also look through it and you will get something.
2. Reasonable choice of image format
We all know that the quality of digital photos is related to the pixel (resolution). The higher the pixel, the better the image quality. According to the actual situation, a 2-megapixel digital camera has the same digital image capturing ability as a 1200 dpi scanner, while a 6-megapixel digital camera can be regarded as at the same level as a 2400 dpi scanner. If only the general platform scanner is used to digitize the photos, the digital camera can easily surpass the 35 mm camera as long as it costs 2 million to 300 million Vientiane. But if the output is 4 "X6", which is about the size of A6, 200-300 Vientiane elements can meet the needs of ordinary people. But if it is only used for the 72 dpi display screen of the computer, the requirements are even lower. The resolution is 1024X768, only about 800,000 pixels. Any 2 million-level DC can be easily handled. Because the storage space of digital cameras is limited, the resolution should be selected reasonably according to local conditions, such as: PC only,1280x960; Generally used in my Sony DSC-S75;; For printing,1600x1200 is generally used; Of course, use 2048X 1536 when taking photos of life. In the case of low requirements, the compression STANDARD also adopts standard, which saves half more pictures than FINE's compression standard!
3. Writing and thinking
For users who have a certain understanding of photography, everyone knows the importance of accurate composition. For example, if you don't take a close-up, you should generally put the subject at 1/3 of the picture, and try to avoid the messy background and shoot from a special perspective to capture the details and personality of the object as much as possible. Using some diagonal or arc background composition will make the whole picture look more vivid.
In addition, we should be good at observing with two-dimensional eyes. Because photography has only two-dimensional space, it expresses the sense of space through perspective (that is, taking the modeling effect of light and shadow as the reference object), which is different from three-dimensional human eyes observing things from two different angles. However, most of the current digital cameras are direct-view LCD viewing screens, and the field of view ratio is above 90%, and some are close to 100%, such as S75 and 99%. We can directly observe whether the sense of space and distance is enough and make adjustments in time. However, the LCD resolution of general digital cameras is relatively low, and the definition is generally unsatisfactory, but the pen is still satisfied with S75. But you can't be superstitious, because in practice, it is found that the exposure in LCD is slightly overexposed, and the exposure measurement in computer display is just right. This is also the reason why the photos taken by some users are always dim. Moreover, the power consumption of LCD has always been a headache for color friends, so many color friends are still used to using optical viewfinder when shooting. Considering that the field of view of optical viewfinder is only 80%-90%, remember to be off-axis when shooting close-ups! Of course, if you want to make a spectacular picture, you have to close one eye, build a "picture frame" with your thumb and forefinger, and imagine the scene in front of you as a picture printed on a book or hung on a wall. ...
