Exercise – Focus at different apertures

So in this exercise I will take three pictures. And I will take the first picture with the lens at its widest aperture. Take the second with the lens stopped down to the mid-point of its scale of numbers. Take the third with the lens at its smallest aperture . Need to look for some information on how to set my shutter speed to be fixed in order to get the same exposure with all these three pictures, so I’m heading over to my cameras manual.

What I have done now is allot of reading and research about shutter speed and aperture and how they work together. I have added this additional information to my first project in the course ” Get to know your camera”.

I will now Adjust the shutter speed so that the exposure stays the same, even though I’m changing the Aperture from Wide – Mid – Narrow. Here is how I do that, “Aperture Priority” mode, I set the lens aperture, while the camera automatically sets the shutter speed.“Aperture Priority” The camera calculate the shutter speed for me. I even made my own sign for this mode.

So now I have been out in the dark again, just like our wild animals that comes alive with the sun goes down. Firstly I packed up some firewoods in a row on the grass and took three pictures with different apertures,  however it didn’t seem enough with just using the flashlight, but I did some tries and finally I moved the firewoods and turned a stronger light source on, a 1000 watt lamp that is attached to the house and that helped. I will post six pictures here taken 3 from one angle and the other 3 from another angle, cause I thought the result was some what different. Again, I didn’t have a tripod so I used a bucket as one and I was laying on the ground when I took these pictures. the first three is taken from the left side and the other three are taken from the right side.

The first three pictures here below I did crop to get rid of some background.

Picture No 1:

ISO 400

F- stop 4,2

Exposure, shutter 1/2 sec

Focal length 34mm

Picture No 2:

ISO 400

F- stop 11

Exposure, shutter 3 sec

Focal length 34mm

Picture No 3:

ISO 400

F- stop 27

Exposure, shutter 15 sec

Focal length 34mm

I felt that I needed to do another try from another angle to compare the difference from the three here above. The three below are also cropped. Thought it would be best so in order to see them better.

Picture No 4:

ISO 400

F- stop 27

Exposure, shutter 8sec
