Demonstrating shutter speed

I bought a tripod a couple of days ago and had never used one before and decided it was time to play around with my camera's shutter speed in order to fully understand its function instead of continuously reading up on the subject. I simply waited for the night to draw in then I set my tripod up (making sure this was done in a safe environment with no leads or other obstacles in the way). Using a tripod allowed the focus area to be completely still as I have tried to experiment in the past with shutter speeds with the camera in my hands and the image always ended up a visual mess. I positioned my tripod so it was facing my open window and angled my camera so it was focused on the trees in pitch black. I set my ISO onto 100 (I wanted to have the best quality image possible) and set the camera's shutter speed to various different speeds. I really found this exercise helpful and it fully made me understand how extending the shutter speed will inturn allow more time for light to enter the image. Below shows 5 seperate images of exactly the same image (I didn't move the tripod)...The images speak for themselves.....

I firmly believe that I could only do this experiment by using a tripod and my correct selection of kit here allowed me to demonstrate the below images

Image 1 - SHUTTER SPEED = 4 seconds (Image represents minimal light entering the lens hence a very dark image)
Image 2 - SHUTTER SPEED = 8 seconds (Image starts to get a bit lig
hter)

Image 3 - SHUTTER SPEED = 13 seconds (and lighter......)


Image 4 - SHUTTER SPEED = 20 seconds (and lighter......)

Image 5 - SHUTTER SPEED = 30 seconds (You get the idea!!)

  1. Hi
    The fact you are demonstrating you exploration of techniques and taking your own photographs to display this shows good practise.
    Also ticks off 1.1,1.4,1.6,1.7,1.8,and 2.2
