PHOTOSHOP

I used the tutorial on how to change hair color, this is the website: http://tutorialblog.org/photo-retouching-change-hair-color/

Everything was pretty easy except I had trouble on getting the orange to start this was because the white square at the bottom of the left on photo shop was in front of the black square. MAKE SURE THIS DOESN'T HAPPEN TO YOU!

DEPTH OF FIELD PICTURES

Here's a picture of the pink dinosaur and the t-rex out of focus and Steggy in focus:


This is a picture where just where the pink dinosaur is in focus:


Here all of them are in focus:

DEPTH OF FIELD

The depth of field is the distance around the focal plane which is very focused. Or when you see a picture such as the one below where one subject is focused, but the aren't as focused. Two things that affect the depth of field are the aperture and the focusing distance. When you have less aperture you can see farther or in other words it won't be so blurry. The focusing distance is using your zoom on some cameras or on other just adjusting the lenses.

TYPES OF PHOTOS

Blurred Action: This is when the photo is taken with a slow shutter speed. This doesn't mean the whole photo needs to be blurry it can just be the background or something. Also for a great blurry picture you can adjust the exposer time.


Stopped Action: This is when the shutter speed is very fast but still the picture is very clear. It is almost like a normal photo unless you somehow make it blurry. An example of this would be the picture of the tennis player about to hit the ball.


Panning: Panning is the effect which the camera or the video camera is moved horizontally or just scanning the subject. People who are most likely to use this is a photographer or someone filming a movie or just in general. You can set the shutter to different speeds to capture different effects such as slowing it way down (1/15 or slower) and freezing the picture.

Blurred Action:

EXPOSURE

Exposure is the amount of time is it takes the for the light to come in. Pictures can be over exposed or underexposed. Which means some tend to be darker and some tend to have too much light. Along with just over exposer or under exposer there is also the shutter speed and then aperture. The shutter speed is the speed in which it shuts, it is measured in fractions of seconds. The aperture the lens taking in the light and for a certain time, aperture is measured in f/stops. f/stops are on scale from f/1.4 to f/22. to calculate the f/stops you must use the formula, see below. Shutter speed and aperture relate because the shutter is when or how much light is expose to the sensor. Shutter is measured in 1/2000. Aperture is measured in f/stops and is how much light is let into the camera. Some camera settings that let you use aperture and shutter speed is manual. Metering is when you have automatic exposer.

Heres's an example:


Here is the formula:

TIRE

This is a picture of a tire in my backyard. It was placed there to hold down the tarp that you can see in the background.

Las Vegas 2007

On Spring Break this year Megan and I took a trip to Las Vegas, here are some pictures of our trip:

Andy Worhol

One of my favorite photographers is Andy Worhol. The first time I ever saw his work was in 8th grade when I was doing a project on Marilyn Monroe. Andy Worhol was born in Pittsburg in 1928. Through out high school he was very good with artwork and later graduating in 1949. He overcame many obstacles and achieved many first. He was the first one to have a one man showing at the Hugo Gallery in New York, and also worked for Vouge and other top magazines. He was thought to have a very strange personality and was nearly killed during his life. On February 22, 1987 Warhol died due to complications of his gall bladder. Nearly 2,000 people attending his funeral.

Here is some of his work:

CCD

Name: Sydney Course: Digital Studios
Date: 9/25/07


CCD →
➢-Charged-Coupled Device
➢-A sense light and facilitates the recording of an image in digital cameras and scanners.
➢-A computer chip that contains a grid of a coupled
➢-Has the capability to store energy and pass it to other capacitor

Capacitor →
➢ Represents one pixel
➢ The smallest image element a camera or a scanner can record
➢ Example: A 3.1-megapixel camera will have 3.1 million capacitors on its CCD.

How does a digital camera work? →
➢ The light passes through the lens and lands on the CCD. CCD shoots light at each capacitor, and then records the information onto memory.

How does the CCD work? →
➢ Light (photons) travel through the lens and hits the CCD.
➢ Photons that strike the atoms will free electrons.
➢ More light frees more electrons, less lights frees less
➢ A circuit at the bottom can measure the voltage of each element in the last row
➢ The remaining rows pass information (electrons) to another row that is below which is in turn red, this process is repeated until read.

Video Cameras →
➢ A video camera moves much faster (up to 40 times faster).
➢ A standard video camera has a resolution of around 640 x 480 reads about 307,200 capacitors 40 times a second (12,288,000 capacitors per second.)
➢ This procedure can only record a certain amount of light. For colored images the most common method is Bayer Mask.
Over each set of four capacitors 1 is filtered blue, one red and 2
Green. (uses more green because the human eye sees more green.)

Luminance →
➢ Amount of light
➢ A luminance is recorded on each pixel but color information is much less.
➢ One luminance is worth 500,000 (pixels 250 red, 250 blue)
➢ The final picture is a average of the grouping of pixels
Interpolation→3 CCD’s→
➢ Some cameras only use this→ light passes through the lens into a “beam splitter”→red, green, and blue.
➢ The image is high quality and usually expensive.



Summary: This article was mostly about digital cameras and how they work. One section in the article is about video cameras and how they work also. You also learn about CCD’s and how the small screen on a digital camera works.

What I know now.

I know..
-That not all cameras need batteries.
-They all need a lens and a shutter.
-When you take the film out it needs to be dark if not your picture will not turn out.

I don't know..
-Will we develop our own picutres?
-What camera takes the best pictures?
-Will we use just our camera?

Pinhole Camera

For the past week or so we have been working with pinhole camera's. We have learned how to make them, how to take pictures with them and fix them. Our group went through two pinhole cameras. The first camera was made out of a pringle can, after we finished it Hiller told us that it would not work. The next day we started on a new camera that was made out of a box. From what it looked like this camera was really going to work. We finally got all our problems worked out with the paper and keeping the light out. We went out into the hall way to take the picture and everything seemed fine until Hiller told us that only one picture came out.

This is how a pinhole camera works:




Our final camera consisted of:

-Smaller box.
-Duck tape which covered the hole on the box and used as the shutter.
-A piece of carboard to support the film paper.
-Film paper.
-Plastic bag.

How we got there:

First we taped the box shut and made sure that it was light tight. After that we cut out an area so the paper could go into the box, this was held up by a piece of cardboard so the paper wouldn't bend or fall. We also had to put a small hole, made by a tack into the box. This was used as the lense, which was covered by a piece of duck tape which we used as the shutter. After all that was done we needed to put the film paper in, without letting the light hit it. We did this process in the black bags. When we were all finished we went to talk a picture. For our picture we used a binder we found and proped the camera up so it would take a picture of the right thing.

After we were completey finished we went into the hall way and took a picture of some flowers. I'm not sure if ours was over exposed or under exposed but my guess it under, because we only set it out there for three minutes.

The whole purpose of making this camera was understanding how the first camera can still relate to a camera we use today. Or to just show that you can take a picture with this camera too.

The whole experiment with the pinhole camera was a good one overall, enough though our camera didn't take a picture. I really enjoyed learning about camera's and how they work, and now I even know how to make my own camera. I can also use the information that I learned and I can show someone else what I learned.

Here are some pictures of us in process:

September 5, 2007-DIgital Studios

In this class I hope to learn about how to take better pictures and
different ways to edit them. I would also like to learn more about
cameras so I can use that knowledge later in my life. I am also
looking forward to learning about the settings on the camera. Over
this semester I hope to learn a lot more then I do now!
