Photogram Positives

I used the enlarger to transform the negative photogram into these positives.

Photogram worksheet

Photogram worksheet

1.) Don't let any light get to the photo paper.

2.) You can achieve black by allowing light to shine on the paper.

3.) You can achieve gray by allowing only partial light to hit the paper.

4.) Photograms are created in the classroom because you can't see anything in the dark room.

5.) You have to make a test strip to test how much light needs to get on the paper in order to get a perfect photo

6.) Photograms are photos that achieved by using the enlarger which uses light to get white,black, and grey. This is why its called painting with light.

8.)The developer brings out the light in the paper and makes the image visible.

9.) The stop bath stops the developer from developing.

10.) The fixer makes your paper no longer light sensitive.

11.) the fixer remover removes the fixer.

12.) The final 3 minute wash washes all the chemicals off of the paper.

Photograms

I created these photograms by placing the photo sensitive paper onto the enlarger and not letting any light get to it. Then i adjusted the enlarger to have a clean crisp edge and set it to F8. i then took the photograms and put them through the developer,stop bath, and fixer. 

Positive Pinhole Camera picture

In order to turn my original negative photo into the positive one seen above, I first made a test strip with the enlarger to find what number on the enlarger produced a positive image. Then i made a finished product with the enlarger.

Pinhole camera worksheet

1.) A camera obscure is a darkened box with an aperture for projecting the image of an external object onto a screen inside. 

2.) A pinhole camera is a closed light tight chamber with a pinhole aperture and no lens.

3.) All cameras have a shutter, an aperture and are light tight.

4.) The shutter and the aperture allow light to come in.

5.) In order to test the camera for "light leaks" you go outside with a test strip inside your camera and let the camera sit still for 10-20 seconds without lifting the shutter. then you develop the test strip, if your strip is white then this shows that your camera is light tight, if the strip is black or grey it means it is not light tight. in order to fix any light leaks you may need to make your camera more secure by covering it in more black paper, another problem that can cause light leaks is if your aperture is to big.

6.) Camera shake takes place when you moves the camera while you are opening the shutter, to avoid this place the pinhole camera on a flat stable surface.

7.) The developer transfers the latent image into a visible photo.

8.) The stop bath halts the developing process by washing off the developing chemical
9.) The fixer stabilizes the image, removing the unexposed metallic on the photograph.
10.) Agitating the chemicals when printing because it causes the photo to develop with fewer flaws such as streaking and staining on the finished product.
11.) To prevent prints from sticking together by laying the pictures spaced out in the tray.
12.) We wash the prints to get all the chemicals off of the finished product.

The point of this assignment was to teach us the rules of composition and how they are applied. These rules will help us to take proper photos throughout the class.
