Vignette
Vignettes happen naturally when more light reaches the center of an image than is reaching the edges. Although you can change an image into a vignette style by using Photoshop. 
Optical vignetting occurs in all lenses. Depending on the optical design of the lens, it can be quite strong on some lenses, while being weak on others. It can commonly be seen with wide angle lenses and those used with wide open apertures. 
Physical vignetting is caused by a something stopping light from hitting the sensor. It can be caused by anything preventing the light from coming into the sensor. For e.g. A filter.




Cyanotype
Cyanotype is a photographic printing process that produces a cyan-blue print.

The cyanotype process can be created by:

Mixing chemicals
The cyanotype is made up of two solutions.

• Potassium ferricyanide and Ferric ammonium citrate are mixed with water separately.
• The two solutions are then blended together

Preparing the canvas

• Paper, card, textiles or any other naturally absorbent material is coated with the solution and dried in the dark.

Printing the cyanotype

• Objects or negatives are placed on the material to make a print. The cyanotype is printed using UV light, such as the sun, a light box or a UV lamp.

Processing and drying

• After exposure the material is processed by simply rinsing it in water. A white print emerges on a blue background.
• The final print is dried and admired.

Solarization
Solarization is used to create extreme cases of overexposure but is known as an effect that is applied in a darkroom to black and white images. The visual effect of a solarization is that it inverts the image to make it look like back to front. So the white an black in the photograph is switched around. This is to make a mono photograph look like a cross between a positive and a negative image. Inverting an image is a common process used on photoshop in modern days so Solarization is not as common.

Polaroid
Polaroid cameras don't look modern when it comes to camera. They are designed to be like old fashioned cameras which still take good colorful pictures swell as black and white. As you can see from the photo below, the picture is still colorful, however the color is not as dramatic and as vibrant and the modern photos.
