Simple Manual Photography Tips

Photography Course. It is likely that this issue be a little complicated if this is the first contact with the subject. But it's worth, I can guarantee that if you understand this you will have taken a big step forward to master photographic technique and, from here, your learning rate will be multiplied. Now that you know what are both the shutter and aperture is time to put our service to fully achieve the pictures we want. Shoot using manual modes is the way we will fully when taking pictures and getting what we want freedom.

All SLR cameras and most of the middle and have advanced compact manual shooting modes. Usually the following:
  • P: Programmed Auto. The camera operates as in the AUTO position, but allows the parameters to be varied.
  • A (on some cameras appears as Av) Aperture Priority, ie, aperture priority / aperture. For a given (user) diaphragm, the camera calculates the speed at which to shoot (opening and closing the shutter). This mode is useful for shooting when we want to control the depth of field.
  • S (some cameras appears as Tv) Shutter Priority or speed priority. The camera calculates the openness needed to achieve correct exposure from a speed selected by the user. Prioritize speed to interpret the movement in our exhibitions.
  • M: Manual. Everything is controlled by the user.

When it comes to shooting in full manual mode, M, the meter or meter that all cameras have become an indispensable tool to calculate the correct exposure. Gradually, with practice, you will go to develop the ability to find out the correct settings for the situation. Although you will always have the support of the meter to see if your intuition is taking the right path.

The simple mechanism to indicate if the chosen exposure settings will be correct, if the picture will be overexposed or if instead be dark and as a result we get an underexposed image. It also tells us how much of this over or underexposed. What we try to achieve in normal conditions always going to be a correct exposure. Therefore, the indicator is located under the 0.

How do they interact the aperture and shutter?
We know that a well exposed photo is achieved if the amount of light reaching the sensor our camera is adequate. That this is so depends on how we configure the aperture and exposure time. Varying any of these parameters directly affects the amount of light that will enter our camera and therefore the outcome of our photo.

We talked shutter and aperture. To study the interaction between these two parameters, we start from the classical scales diaphragm aperture and shutter speeds.
  • Classic shutter speeds: 2 "- 1" - 2-4 - 8-15 - 30-60 - 125-250 - 500 - 1000 to 2000
  • Classic diaphragm openings: 1 - 1.4 -2 - 2.8 - 4 - 5.6 - 8 - 11 to 16 -22

In today's digital cameras, you can find intermediate steps both diaphragms and shutter speed. This is not bad, on the contrary, it is good, since it will allow better adjust the exposure to the light conditions. But we learn how to interact using their classical values.

We must assume, as a rule, every step climbed classic diaphragm means that our camera enters half of the light coming in the previous step. On the contrary, when we came down a step, the amount of light entering doubles. The same applies to the shutter speeds, went up one, the amount of light that enter into our camera will be half. On the contrary, when we came down a step, the amount of light that will enter will double. Knowing this it follows logically that there is no perfect combination of shutter speed and aperture diaphragm, as there are many that are equivalent. Choose one always depend on the effect we want to achieve in our photo.

As shown in this example, to go slowly closing the diaphragm are prolonged exposure times, thus counteract the light that is leaving to enter the close the diaphragm. Despite the change of parameters, the exposure is identical in all three photos, but if you click on the image to enlarge it you will notice that more and more depth of field. Remember the relationship between the depth of field and aperture?

I NEED MORE LIGHT I open the diaphragm or MAKE A longer exposure
We based on certain parameters can cause more light to reach our sensor or by opening the diaphragm or by longer exposures. Remember that any combination is perfect, it is good as long as the meter tells us that it is. It all depends on the lighting conditions and, above all, what we want to achieve. Tomorrow we will see some practical cases.
