Photography Week 5 final week of the carousel

This week on the carousel we went to photography  we learnt  the anatomy of a camera and how it works. The two types of cameras we explored were: a DSLR (Digital lens reflex and SLR (Single lens reflex)


Looking though the view finder allows you to take a picture.


An SLR camera allows lenses to be changed , this can be really useful when sports photographers want to use a long lens to bring the subject closer.

How a camera works:

1. Light comes though the glass , inside are convex and concave lenses so light gets bent back into the camera body. This is the aperture it controls how much light goes in. The  wider it opens the more will go in and the  smaller it opens less light  will go in
2.  The mirror is what makes it a DSLR as lenses are upside down  so the mirror turns things the right way up.
3. When the mirror flips up out of the way the shutter speeds records the image .

A digital has a lot more mechanics then an old camera . Digital camera image is recorded on a chip and an old camera it is recorded on film.

Processes:

Shutter speed:
Working between aperture and shutter gets the exposure right.


A fast shutter speed creates short exposure and freeze motion . E,G 1/000s 1/2500s for capturing sport.


A slow shutter speed creates a long exposure and blur motion for interesting effects e.g 1/15. This lets more light into the camera to these effects.






Aperture: creates a shallow or sharp depth of the field. The bigger the F.stop and  the smaller the aperture and   the bigger the aperture the smaller the F.stop.




Using a bigger aperture  creates a shallow depth of filed .

Using a smaller aperture crates a sharp depth of field

Processes:

Shutter speed

To get a sharp shutter speed turn the dial at the top of the camera to the 'S' symbol. This helps  the shutter speed as the main priority on the camera. To change the shutter speed on the camera use the left and right arrows on the ok menu at the back.

Apature:

To choose the aperture on a DSLR set the priority mode on the camera to 'A', Turn off LV which stands for Live view.  

Here is a image of the dial :

Here is a picture of the aperture setting screen:

We experimented with shutter speed and aperture  by taking different photos outside:

Here are  some examples:

Here is a photo of someone running . This photo was taking using a slow shutter speed. This is because the subject is blurry.

method:

I used a Mono pod , which  is a single tripod used for taking photos it is important to use a tripod when using a slow shutter speed as  it creates longer exposures . This will stop any shakiness and it captures  the motion of the subject. For example in this image you can see the motion of the subject running. However this the was not set on a very slow shutter speed as the background is still visible.

This photo was taken with a slow shutter speed.

Fast shutter speed

To compare fast shutter speed with slow, this image was taken using a relatively fast shutter speed as the object is not blurred . However  it's not very fast as the subject appears to be out of focus a bit.

Depth of field

Depth of field allows the camera to focus on a certain point of the photo  and make it blurry or sharp , depending on what the camera has been set to focus on. For example in this picture I  took of someone holding a tomato and a plaint I  set  the camera to focus on the plaint  I wanted to achieve a blurry effect . To do this a used a shallow depth of field by using a smaller F.stop and a bigger aperture. The result was the plant appeared  fuzzy and blurry.

In the second photo I used a sharp depth of field . A smaller aperture and a bigger F.stop was used in this photo. Using this technique makes the focus point stand out and be clear compared to the other picture were it is difficult to make out the plant.

The tool I used to take these photos was a DSLR .

The method I used to steady the camera when taking these photos was a mono pod attached to my chair as I sometime shake the camera with my hands.
