I also say a few words.
First,
cheap nba jerseys, you have the purpose of photography. Of course, everyone has their own may require. For example: Some people mainly on the record, some people may require higher image quality. This has a question: What you have to have equipment to meet the requirements? Is not a technical exercise to a certain extent, it can make up for lack of equipment? Some people will ask shooting skills: such as composition, exposure and so on.
can enjoy the photo if the degree is concerned, is more and more, including personal photography, personal aesthetics, photography, and enjoy the orientation. In addition to meeting these requirements, you need equipment, do not waste as much as possible. The so-called value for money.
Let's take a look at equipment. Now camera equipment, cameras. At present, both devices have the function of emphasis. Some functions that overlap. From now on development, the overlap on the rise. Such as: the Nikon D90, D300s, D3s. Canon for more. Photos and video are very terrible. If you do not consider handling, SLR picture quality is completely beyond the home DV. The SLR's handling, but not the short version of the seabed. Not discussed here.
we look at the characteristics of underwater photography. Media issue because the water will consume red and yellow light, which creates photographs taken at sea on land, we need to have lost the color of wood to restore it, so that the true colors of the rainbow is our hope gorgeous. That there are ways to do that?
A
1. Artificial light. This requires flash. When shooting macro, from the relatively recent, the light turn back in several times, the color is quite normal (restored back), but shot wide when only relatively close to the object (or body) of the color reproduction out of and more than 1M, for wood has a solution. Think about it, even the sun's rays all to eat (red, yellow), not to mention a little flash. The other is the time of the shooting, set the custom white balance.
2. Later adjustment. Regulation of the general picture has a certain scope. Good material (photo), adjust the room for large (this and the camera records the format of the performance and related). We usually call it photo tolerance. Actually take to restore the color out of the sea, is the late custom white balance bottles (this is a bit complicated to go search, and look at some photography site)
while the camera records is now generally have two formats: JPG, RAW.
JPG is a photographic camera sensor data read by the camera chip processing out of the common photo formats, remember, this is treated in the format, so some of the data, the camera that make up needs have been removed. And this format in the late tolerance of small (that is, very little room for adjustment.)
the RAW format is a data packet. View to have a certain software, you can usually make direct upload the site, to convert to JPG or other picture formats. The RAW format, according to tolerance is very large (of course there are certain limits, we must first make a good, can play his late tolerance)
, of course, RAW's much larger capacity than JPG.
3. Focus faster. In general, the water timber with the conditions on land, you can take your place, then the fish will be very mobile, or the sea are pushing you from side to side. Fill the same way as the focus, the focus SLR is very fast. The DC is slower. That is why in submarine photography, SLR clarity are very good reasons. In addition, the light-sensitive sensor SLR much larger than the DC, which resulted in tolerance SLR photos and illumination in the case of the end of the performance of a very good reason (this is not to elaborate.)
4. To a good photo, we must learn to late. Especially the digital age, no post is a waste. Like to give you the Feast, and you eat when forage, it would mean that sin. Now many of the software can adjust the picture later. Such as: PS, lightroom, etc., just have to learn one, the other essentially the same principle.
, of course, the later is not a ######## I said
from the above mentioned, we have a basic understanding of the underwater photography features. Choose what kind of equipment that was appropriate?
us for the next DC
1. DC photos, of course can not be compared SLR (deficiencies),
barcelona jersey, this is not the camera behind the wisdom of the head can be used to make up. However, people have different preferences, different degrees of Feng Jian. In DC there is relatively good DC to pick that becomes the key to the selection.
2. First, select which to focus in fast DC DC (this is very important), each focusing speed of a DC is not the same. Like Canon's G10, G11 is a good choice.
3. Another must have RAW format records are so late you can have some room for adjustment (including color, restore, etc.).
then there should be appropriate to record the fast pace. Especially when you're shooting and took a,, this time you find a lens in front of the camera because the photos in the record and can not press the shutter, what would you feel?
4. If you have met the above requirements, you can compare a wide angle camera with a selection (equivalent to 135, remember). Because the water has 1.3 of the refractive index. This is why more widely in the water the better because the lens. SLR with many of the fish eye, fisheye view because almost 180 degrees out.
addition, there must be supporting the shell
Here today, the first
it, even wood have never had so many characters
code above proposals for reference only, please also inadequate understanding.
SLR a few days I said in the next, and encourage one another, along with progress.
Thank you brother upstairs join. Tomorrow off to Fiji due to the. First off the ground, come back to add. Since it is photographic, photography now we have to mention was the main equipment: SLR. DC high-end than a 135 system, medium format, large format. Here is not on the medium format, large format and digital back repeat. Interested to know how much your friends can under their own needs and the improvement of photography there is a certain benefit.
A. We are now playing the photographic equipment is typically 135 system. The main features and performance of SLR (and DC comparison): 1. Excellent performance of the camera body control, focus performance fast, accurate and fast storage available with a choice of function room for large. . . 2. Great light sensor: Many people just starting photography friends have to understand this, do not know why. Light sensor the size of the impact of quality is very important, generally the size of the sensor sensitive to differences: the same as the size of the sensor film 135, which we call fully. The other is the non-fully (APS system). At present, if it is heavily, the prices are generally more expensive. Two years ago, the basic is heavily dominated Canon: 5D series, and the 1Ds series. When the Nikon D3 after the Canon out of a broken dominate. Sony had last year out of the a900, from the formation of the three pillars of the pattern. So the current SLR photography has gradually leave ordinary people's horizons, and can feel fully the charm.
3. SLR lenses can be changed: each has his use of a lens (also varies) from wide angle to super telephoto. Lens zoom and fixed focal points. In general, the fixed focus zoom imaging performance than good. The zoom convenient (especially travel) in some specific situations is almost impossible to replace.
as 1,2,3 and so these reasons, resulting in a high-quality SLR picture quality, and can be a wide range of purposes (eg, magazines, posters, etc. 。。。), of course, there are limits. More than this capacity, it would need a large format.
B. Non heavily choice of camera is very large. Because of its light-sensitive element (sensor), than the heavily small, relatively inexpensive and many. The imaging is absolutely unambiguous. Generally in proportion to the size of the sensor 135 defined, Canon in general is 1.6, while the Nikon is 1.5. APS system also has the same high-end and low end. Because the structure of APS is different from not the same as the flange, etc., can generally be used in the lens fully machine can be used in APS machines, and machines developed specifically for the APS camera, can not generally be used in fully on.
C, APS system in the choice of the time, the main consideration of the focus performance of the fuselage. Especially in the end of illumination conditions. Because underwater photography is generally darker, conditions are relatively harsh point of land, especially in contrast to small, low illumination limit cases, the focus is the test performance of the machine. This example (which may not necessarily exact): In the film manta, you focus on this to his belly, and belly of the contrast between the small and may not be in focus the camera, it would mean that a surprise might have missed the scene? If the focus performance is good, the chances of success on the big.
In addition, the fully beneficial, but most people do not see the difference between fully and non-fully (including myself). But another trend heavily,
cheap minesota twins jerseys, especially in the rapidly changing digital era, the era of full-frame progressive civilians in the flower.
choose a suitable underwater SLR photography has become not so far away
in the choice of SLR, when possible, the choice of manufacturers of. Currently the first camp: Canon, Nikon is the first. Canon 1Ds series from the 1000D to the Nikon D40 to D3x, very wide choice, and waterproof shell is also more choice, there are also high-end low-end. Was divided into different materials (plastic, aluminum, carbon fiber, etc.), as subal higher-end, while the sea & sea, nexus, etc. is the high end. . . .
D. In the special instructions, select SLR cameras, when the current terms of choices as far as possible the choice of the newer models. Because as the development of digital, video and photos to gradually become integrated. And to the present situation, the quality of the video SLR has been completely beyond the broadcast of the DV, and ordinary household which can not be compared DV: Of course, manipulation of the video SLR has its shortcomings, and this shortcoming in the water almost nonexistent. The video quality, watching on the big screen, magic is simply a kind of beauty to enjoy. These videos can make you long-term preservation. Just think, if the 100-inch projector, watch, perfect quality, clearly visible manta, clownfish amusement position, details of the performance completely. . .
I used last year 5D, this year for the 5D2 (only for his high-definition video), under water, the two top things Rangou feel a lot of fun: photos, videos. And qo are the previous JVCHD7 though with a good crust, now lying at home base as much as possible choose
1080P video capability (note: not 1080i). This may increase your expenses, and these expenditures will not make you regret it
C. SLR Lens configuration: Underwater general to two lenses: macro and super wide-angle lens. Select the time (of course there must PORT) macro can choose the number of general trees. Relatively wide points. The wide-angle wide-angle fish-eye lens and zoom lens. Generally shoot scenes relatively large fish-eye is very appropriate, but also has its disadvantages: a large distortion, which may be detrimental to use the video function, and the other characters in the film when the water deformation, the shooting may have to master certain skills can only be appropriate to avoid the annoying distortion. The zoom wide-angle, convenient, small distortion, especially the zoom, can be applied to different scenarios and so on, but not as good as fixed focal imaging and fish eyes, people choose is really difficult. I recommend choosing the zoom wide-angle, of course, mainly in their own personal preferences.
then under the SLR underwater for the price (not including the camera, the camera lens.) The price generally between 3-10W. The choice of 3.5-4.5W for good. This price includes the basic accessories (of course, if you want special effects, will increase spending, such as: close-up lens, focusing light, video light, special filters, etc.)
D. SLR into the water also has very many shortcomings. 1. First of all, people who like photography may be a lens, is extremely concerned about the scene, and will spend a lot of time to shoot. This may cause you wood have time to enjoy more views of the seabed (and non-SLR to get people more) 2. Often possible to focus the camera when the degree of the problem, often forget the decompression time. And may affect the whole diving large forces (together,
kobe bryant jerseys, the total with the Sheung Shui to it)
3. Another buddy to have a certain degree of coordination (including on your tolerance.) Potential partners might make to the current model, or when you take pictures, he may do nothing, it may affect his diving fun, etc.
4. Travel. SLR underwater because the general device requires a compression of the box, installed,
minesota twins jerseys, the weight 15-25KG. This may cause trouble on your trip. Division has a major airport baggage restrictions, we might have more clearly. So you may have extra amount of wood to check the other equipped with a (BC, fins, etc., which may include daily necessities), if a fine experience, it may have expensive than your first class.
play photography, I think it is to be combined with the camera man. Times, then how about?
must first understand the people, and then understand the camera.
1. People, you see the actual image, the object is the reality of light through your imaging unit (eye) and brain, and then processed through the formation of the brain.
2. Camera is physical in nature, he did not mind so advanced, will be very faithful record of the image (such as depth of field 。。。)
So the maximum understanding of your camera, so that your ideas and the same camera, then you must can be a very good picture, this requires experience, wisdom. . .
play photography, is to play the aperture, shutter play, play the white balance, color temperature play, play with light. . . Of course, the digital age also play late (in fact, the era of film, darkroom is later), play them in order to achieve your goal, you want to work and effect.
highest level is to play ideas, play ideas. . . Do not know many of us can achieve it?
first shutter. Underwater camera, the shutter to set certain (security shutter.) If you do not secure the shutter inside the screen will be empty of the. Generally depends on whether the action you take, the worse the object. Also depends on your how the neutral buoyancy underwater. If you are a metal hand, in the same conditions, the shutter can be the end than the others. This is a relatively comprehensive. Moving objects will generally beat the shutter in the 100-200 are safe, if it is in the sand, the subject does not move (such as sea hares), the shutter 30 can be. Of course, to the exposure accuracy, with the other (such as iso, aperture, lighting with) parameters.
is under re-aperture (macro), useful for large aperture film, it also took the effect of a small aperture is not the same. Camera aperture is the most basic play, and it is very interesting. Macro lens aperture generally have 2.8-32 months. You can try to 2.8-22 in the water all play each aperture in order to experience all the wonders of the music five poor.
large aperture to blur further the elements necessary to streamline the screen, highlight the subject. The more you play the aperture to play with the more flavor. Aperture effect of the general good macro range :5.6-16 between, we can try.
very important application of the aperture, allowing you to show where the subject stand out from the screen. Secondary reason, like many feel his photography friends, he can give you the underwater macro photography, bringing endless creative and aesthetic, if the aperture used for good, your work has been half the battle.
when shooting macro, be sure to practice good focus, basically means that to play it. For example; shoot beans Dinghai Ma when the focus in the eye, if in other places, photos, scrap it. To be fixed in the water your body (hand, or by Tintin rod,
nba jerseys, a hand can also be fixed, the camera mounted on a fixed arm, to ensure the accuracy of focus.) Position must be stable, because once in the macro range, the depth of field is very small, little one move, the focus will be gone. . . .
in macro shooting when the focus can be to practice, practice makes perfect. The distribution of light on the most verses. Focus Technology is completed, if the distribution of light is also very good, that picture is considered 80% completed, the work has entered to enjoy the out.
macro in the film, when many people are facing cloth of light, this kind of work, clarity is possible, however, the lack of a three-dimensional. Of course, you need to, this is also an option.
generally side light, and even the side of the backlight, or a top light, so that there can be three-dimensional performance. Normally under water, SLR are two lights, two lights to adjust the output, the general output of small point near the camera, while the other side of the top light or backlighting to the output bigger, so will the transparent sea creatures features to show it. At present there is no uniform method of lighting, and even Japan, Europe, and so light that it is not the same cloth, which requires more exploration of underwater photographers, and more groping to find its own habits and have a unique way.
In fact, the most difficult in the underwater light cloth. If you want a higher level of underwater work, it must solve this problem, or to raise difficult. The art of light and shadow. . . Lu Manman its repair Xi. . . .
again, Macro, completed the aperture, light fabric, that is, the angle of shooting marine life (or a composition), the most difficult, the proposed works and more optimistic, more experience, you must be able to do, this is the idea question, if you all can do perfectly, leaving you master one step backward: luck.
hope that every diver like the ocean, are able to work out their own satisfaction.
