The meeting continued from the last 2 meetings, exploring how depth of field can be controlled. In this session we looked at how the depth of field can be maximised. We used hyperfocal distance, each participant was asked to find out what the hyperfocal distance is for their camera and lens and take a picture with a subject as close to the camera as possible and a distant horizon with everthing in focus.
This is one of the pictures.... Note, because of the high contrast between sky and foreground the sky has been deliberately over exposed so that the foreground can be examined.
F11, 1 second, iso 100, 18mm lens focussed at 10 metres.
July Homework: This came out of a dicussion in during the meeting. Have a go and we will do some more during the next meeting... Take a picture with a backlit subject (natural light) and the shadows on the subject filled in using an electronic flash. Please bring a copy of the image to the September meeting.
|July Homework results
Take a picture that has a smooth background (out of focus and no detail) and ensure that the subject is sharp.
F10 1/400th Sec Iso 1600. a good attempt. A little reframing to eliminate the objects in the bottom right hand corner would have improved the image.
F6.3 1/250th sec ISO 200.
