1.6 Experimenting with Shutter Speed, F-Stops, Depth of Field and Focal Lengths

Following my previous experiment with different f-stops, shutter speeds and iso I have decided to go out into the field with my camera and take a series of photos to illustrate different focal lengths.

I will be using a Panasonic Lumix G1 camera with a 14-45mm lens, a 45-200mm lens, and a tripod.

I will carry out a health and safety check before starting, for example, carrying the equipment safely over rough terrain, ensuring safety of myself and others whilst on the shoot and setting up equipment. Am I wearing appropriate clothing and shoes, cold/wet weather gear, walking boots, safety shoes. Can I contact someone if I get into difficulty, do I have a mobile phone and will it work where I intend to go. Have I informed others of my destination and what time I expect to return.

I have taken some images click here to view, I used different f-stops in an attempt to illustrate focal lengths, the tree on the left falls out of focus when a higher f-stop is selected and the middle distance is slightly out of focus when a shorter f-stop is used.

I then moved indoors to take some images using different shutter speeds again using a tripod. With the vase I used f3.5but then changed the shutter speed from 160 in increments up to 4sec. I also set the white balance to tungsten to compensate for the indoor lighting. The results show a darker image at fast speeds gradually lightening as the speed slows letting more light into the lens.
