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.

Julie's new hair

Black and White Photoshop

I cropped this picture, and then used the desaturate button to make it black and white.

Four Exposure Pictures

Multi-point, camera centered on subject
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.
  

Spot, camera centered on subject
This one is a little better than the last, and you can see Julie clearly, but the background is still pretty bright.



Spot, camera centered to side of subject (on bright sky)
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!

Exposure and Controlling Exposure

Exposure and Controlling Exposure

• Some exposure related terms to help with the search
• CCD Sensor/Exposure
• A CCD sensor is a charge-coupled device sensor. It proved to be more than a computer memory chip, so it was developed for other uses like signal processing. It is more sensitive to light and is more advanced for imaging sensors.
• 
  
• Overexposed
• This means there is too much light.
  
• 
  
• Underexposed
• This is when there is not enough light and you can't clearly see what is going on in the picture.
• 
  
• Shutter
• A shutter allows light to pass through the camera for a certain period of time. This is used for a light sensitive sensor which captures the permanent picture or scene.
• 
  
• Aperture
• Aperture is a hole or an opening through which light is admitted. It determines the cone angle of rays coming through to the image plane. These rays can also pass through a lens, resulting in higher sharpness and focus. It is an opening where light can come through, and is adjustable inside of your camera lens. It can be adjusted to let in only the amount of light you want to let in in.
  

• Lighting (in terms of photography)
• Photographs are recorded light. We can control the light in photographs by chosing the light the picture is taken in, or by turning lights on or off, chosing the shade or direct sunlight, etc. A camera's light meter takes into account the different settings of the camera and tells what sort of exposure the combo plus the light will create on the film/sensor.
• 
  
• F-stop
• On a camera, there are things called f-numbers. These can be adjusted in steps called f-stops. Each stop has a corresponding f-number and decreases by half of the light intensity from the last stop.
  

• Bracketing (in terms of photography)
• Bracketing is the technique of taking more than one pictue of the same subject, using different camera settings for each. It is useful when trying to find the best shot. Many cameras also have autobracketing.
  
• 
  
• ISO (in terms of photography)
• The measure of how sensitive film is to light. Cameras which dont use film still have the same system that rates the sensitivity, and some cameras will adjust depending on lighting conditions
• 
  
• Metering:
• Metering is when the camera takes a light level reading from the environment of the picture, and selects the best combo of aperture and shutter speed. These can also be changed manually according to what the photographer wants, and there are multiple types of metering which can be set, such as overall metering, spot metering, and center weighted metering.
  

Spot metering- when the photographer is wants to get exactly what they are looking for this is used. IT is ideal is the subject has a long tonal rand and if the background is brighter than the foreground, or if something is too bright or too dark.

Center-weighted Metering- This is when the metering is weighted at the center of the picture and then averages for the rest of the picture.

Multi-Zone Metering- this is also called matrix, evaluative, honeycomb, segment metering, or esp. This is usually the default metering choice on most cameras. The camera will measure the light intensity on several points and combine the results to find the best setting for the picture.

Slideshow

Tyler D

Interview of Tyler D.
• How would you describe yourself in three words?
I would describe myself as a nature lover. I am short and funny.
• What do you want to be when you "grow up"?
I would like to be an astronaut or an activist.

Tyler D, an Italian activist, loves to hug trees in his spare time.
• What would the cover photo look like? What feeling would it convey?
I would be standing in front of a beautiful green plant, and there would be an aura of serenity and calmness.

Important Points

The most important skill of portrait photography is capturing the true personality of the subject, and make them more comfortable and real in front of the lense. Close ups are photos that are framed around the face, and are most commonly capturing an expression, or a glamour shot. Upper body and midrange photos are used for one or multiple subjects. They can be used to mark an special occasion very well. Environmental photos show the subject in their normal habitat, like a student in a school. To capture the essence of your subject you can interview them if you don't know them.

digital pinhole camera

A digital pinhole camera seems really difficult. It would probably have a battery and a shutter thing powered by the battery to keep the light out, and a timer for when to open it for the paper to be exposed to the light. It would probably be in something metal rather than a box, too.

It would probably be really hard to make a digital pinhole camera because everything has to be so precise and the photo paper is ruined really easy. It would probably be easier to make just a normal digital camera, because maybe dust or something could get into the hole, whereas with a regular digital photo there is a lens. And maybe there could be a box that automatically closed around the paper after used to keep it from getting light when it was removed.
