Brain Dump
Exposure, metering, aperture, and shutter.
I am going to write three hundred words about exposure, metering, aperture, and shutter. While making the pinhole camera we learned about these, especially exposure. If we left the pinhole camera exposed to light for too long, the picture wouldnt be clear enough, but too light. If we didnt leave it exposed for long enough, then you couldn't tell what the picture was that was being taken. Also, if there was too much or not enough light it had the same effects.
Shutter speed can be changed to make the picture lighter and darker, and to make it a brighter picture the shutter is slower because then it's longer. There are a few different types of metering, like spot metering, center weighted metering and multi-zone metering. Spot metering lights up the subject that you center your camera on, making it clearer. Multi-zone metering takes different lightings from different points of the picture and puts them all together to use a certain lighting for the picture as a whole. center weighted metering is when the camera reads the light in the center of the picture and determines the aperture and shutter speed to get the best exposure for the entire photo. The aperture is a bigger number when it's a smaller hole for shutters because the size of your lense is divided by the diameter of the whole. The bigger the hole the more light is allowed into contact with the ccd, and the smaller the hole the less light the ccd gets. Exposure, timing, lighting, aperture, and shutter are all different ways one can use to make a clearer or not so clear picture. They all work together and can be changed with settings on most cameras, or can be automatically decided by your camera.

Four Exposure Pictures
There wasn't enough light in the middle to show Julie's face, because the camera used the light in the background.
- Center weight, camera centered on subject
- There was enough light to light up Julie's face, but the picture was still overexposed from all of the light blurring around her head from the window.
This one is a little better than the last, and you can see Julie clearly, but the background is still pretty bright.
Since the camera was centered on the side of Julie, it made the window the subject and made julie dark again, even though it's the same setting.
- Post all to your blog and explain
- What mode you were on
- Why the exposure came out how it did.

homecoming week
Homecoming Week at LaConner High is a real sight. Starting off the week on Monday, was "Nerd Day." Althought most students came dressed as nerds with plenty of school spirit, Julie chose not to participate. Tuesday brought it many great costumes, such as dinosaur outfits and 80's apparel for "Era Day." The week continued to be a success, and on Friday night the long-awaited homecoming football game against Orcas took place. There were many excited fans who attended the game, including friends Keefer and Jared, and Kasey and Cecily. The next night, excited from the big win for the Braves the night before, LaConner students attended the Homecoming Dance at Maple Hall. The night entailed dressing up with friends, taking pictures for families, going out to nice dinners, and dancing the night away. Homecoming Week was a success!
