Photograms

1.) You achieve white on a photogram by blocking all the light from hitting the light sensitive paper.

2.)You achieve light on a photogram by letting light hit it fully.

3.)You achieve gray on a photo sensitive paper by letting light hit it for a little bit or blocking light a little bit with magazine paper or tissue paper.

4.) Photograms are designed in the classroom because you can't design an image in the dark room because you ant see anything at all.

5.) You need to make a test trip first so that you can test the light and how long you have to expose it to the light.

6.) Photograms are referred to as painting with light because you use different objects to block the light at different percentages.

7.) Len Lye, Man Ray, and Michael Flomen.

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

9.) The stop stops the developer from developing.

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

11.) The fixer remover removes the fixer.

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

Negative Pinhole Camera

Pinhole Camera Worksheet

1.) A camera obscure is a darkened box with a convex lens or aperture for projecting the image of an external object onto a side screen.
2.) A pinhole camera is a camera with no lens and a pinhole aperture.
3.) Three things all cameras have in common are the shutter, aperture and they're light tight.
4.) The aperture and shutter allow light to get in.
5.) To test the camera for light leaks, you go outside with a test strip and do nothing to the camera. Don't lift the shutter or it will reveal the aperture. Stand outside for 10 to 20 seconds, then you develop the test strip. If the strip is white it shows you that no light got into the camera, if there is any black or gray it means your camera is not light tight. If there is light you need to put more black paper in the camera or put tinfoil around it, the aperture might also be too big.
6.) A camera shake is when you move the camera while trying to lift the shutter and taking a picture. To prevent this put the camera on a flat surface.
7.) The developer converts the latent image into a visible photo.
8.) The stop bath stops the development of the film, by washing off the developing chemical or it neutralizes it.
9.) The fixer stabilizes the image, removing the unexposed silver halide remaining on the photographic dil leaving behind the re reduced metallic silver that forms the image.
10.) It is important to agitate the chemicals when printing because tis allows the photograph to develop with fewer flaws. It prevents stroking, streaking and the staining of finished paint.
