Title: Weekly Assignment: Capture the same scene using equivalent exposures Post by: PWS-Staff on January 14, 2012, 10:30:00 AM For this assignment, choose a scene and photograph it twice using equivalent exposures. Share your results with other readers on the website. When you photograph the same scene using different shutter speeds, apertures, and ISOs, you can really get a feel for what each does. The same scene photographed with a long shutter speed and a short shutter speed look very different even though exposure is the same. These two photographs were taken at the same place at the same time with the same overall proper exposure, but they look different due to the changes in the shutter speed, aperture, and ISO settings between them.
By using a short shutter speed of 1/60 second in the left image, the cars that are driving down the road are frozen in place and you can distinctly see each one. The photo on the right was taken with a shutter speed of 1 second and the cars became streaks of light. To keep the exposure the same, I also had to change the ISO and aperture. The image on the left was taken at 1/60 second, f/2.8, and ISO 1600 while the image on the right was taken at 1 second, f/5.6, and ISO 100.

At the bottom of the box where you type in a post you should see a link that says "Additional Options..." Click on that link and you'll have some options presented to you. At the very bottom of the options you should see "Attach:" along wth a button that says "Choose file". You should be able to attach your photos from there. Cheers, Malcolm |
