The trouble with tools is to get the most out of them. It helps to learn how to use them properly. It is fairly simple to get a lock of a hammer, but how many of us really know how to program our VCR. I'm leaving I here. Although I can't remember a day before the VCRs, I have a DVD player and would go far as to say that I know how to burn a DVD too. So I thought that this month it explain some of those letters on the dial at the top of the camera. While I am one of the few men who read a manual of the camera, I know that many people do not get very far in theirs. It is not very interesting to read and the language is down dry right. So I'm going to try to help you here.
Letters that I will talk about are what are called recording modes.
It is counting the camera select what kind of photos you are going to be taking what letter on its dial. These allow control two things that determine the exposure, the opening or aperture and shutter speed. Opening is the iris of the lens that allows a measured amount of light into the camera and shutter speed is how much the image is exposed. In general modern cameras do a pretty nice job get the proper exposure and there is much less assumptions about the exhibition which used to be. By allowing allowing address letters: Nikon camera my has the letters P, S, A and M, although Canon cameras used the letters TV and AV rather than Nikon S and A, respectively.
P means programme.
In program mode the camera selects the appropriate speed of aperture and shutter using a pre-established formula. When there is enough light provide an aperture small enough for good depth of field (what is going to be strong in the final image) and fast enough speed to stop any movement of the camera shutter. Starting losing light for a proper camera exposure will begin opening up the aperture and slow down the shutter speed for the same pre-established formula for ending a properly exposed image. When the light begins to really fall start ending up with blurred images due to the fact that the shutter speed is so slow that it cannot hold the camera still enough during the exhibition and the image lacks depth because the diaphragm is open all the way by an image inert flat. Beginners wishing to commence with the program mode until they begin to understand how the whole thing of field depth.
S or CanonTV means shutter speed priority.
At the start of mode program and want to stop action selects these letters. They say that it is a sporting event and want to stop the action of players. Now you have the possibility to select a fast enough shutter speed to do so and still know that the camera will select the aperture for a good exposure. Photographers in all NFL football games have their cameras in shutter speed priority. A rule for a shot of exploitation of labour is that the shutter speed must be faster than the focal length of the lens. For example, if you are shooting with a 200 mm lens shutter speed must be 1/200 of a second or faster. This is because he longer lens, more far-fetched is the movement of the camera.
A or AV mean aperture priority.
When you start the need to control what will be processed as sharp on the final image begin to pay attention to what opening select. An old photographer was asked once how he got those images. He replied, "f8 and be there" now f8 is an opening with enough depth of field to create an image that has good depth and sharpness. Most of a lens (optically) is generally about half of its range to stop f. In the majority of lenses f8 is about half of that scale. In Aperture priority select the stop f you want and the camera selects the shutter speed suitable for a good show, just the opposite of shutter speed priority. Normally I have my camera set to aperture priority for two reasons: first of all I am using a tripod, so really I don't mind what the shutter speed. My camera is held solid rock. Secondly, more than anything, I want to know what is going to be strong in my photographs. The part one more distraction from some pictures that I see is outside the areas of focus that should not be. I use often stops f 22 or 32 especially with a lens wide angle.
M means manual.
In this mode you select both the shutter speed and f stop and determine the exposure of the information of the camera tells him. My first SLR camera was a fully manual camera. Let me make all kinds of mistakes as an automatic camera cannot ever. A person could choose manual mode when the camera exposure is being deceived by difficult lighting or deliberately on or low to expose her photography. Use manual in the study because use a flash meter to determine my exposure and not want surprises of the camera.
I hope that this eliminates some reflections about the mean of those letters.
