natural light: project 39

using faster film and higher sensitivity

 ISO denotes how sensitive the image sensor is to the amount of light present. The higher the ISO the more sensitive the image sensor and therefore the possibility to take pictures in low-light situations.  An ISO of 100 is generally accepted as ‘normal’ and is used in good lighting conditions such as a bright sunny day. In low light conditions, such as a cloudy day or indoors, the sensitivity of the image sensor can be increased to 400 or even higher. Taking photographs in low-light conditions with a higher sensitivity will allow you to shoot without an unwanted flash or handhold the camera as oppose to using a tripod. Using my bridge camera I shot the following pictures using an iso from 100 up to 800:-

100                                                         100                                                  

     

200                                                        200

    

200                                                      400

   

400                                                      400

 

400                                                      800

 

There is a price to pay when using a higher sensitivity and using a higher sensitivity with my bridge camera proves to be a pretty high price. The shots taken with an iso of 100 and 200 have a reasonably good quality, anything above that sensitivity and  the images are flat and grainy under close inspection. When using my camera in very poor lighting conditions, such as indoors, the noise is unacceptably prominent.

 what I have learnt

 The use of a higher iso with my bridge camera is not at all successful.

N.B. Having read reviews on various DSLRs and their iso capabilities, I believe that if I had used a DSLR my findings would have been much more positive.
