Photographic Evidenc

Photographic Evidence

*Silhouette Portraits for middle class, made using backlit shadow that was traced paper.
*Camera Obscura Portable box and lens added to this camera to make a clear image. Then a moveable telescoping lense was added to change the focal point of the image, however the image can't be retained permanently painted.
*Heliograph Made camera image permanent. A plate was coated with petroleum oil which hardened when exposed to light and the locations of the image that are dark remained soft while the light exposed areas hardened. This required an 8 hour exposure. (1827)
*Daguerrotype First permanent photographic process that left a good representation of the image. It required a 30 minute exposure therefore many took the most comfortable position and because they couldn't hold a smile, often looked mad. (Louis Daguerre)
*Ambrotype Glass is used as plate instead of the silver copper. Cost of photography was much less and the amount of chemicals needed was also less. (More portable)
*Carte Photograph Uses paper as the medium for attaching the light sensitive colloid, instead of glass. Paper was much smaller and much lighter medium and allowed travel photographs to be taken.
*Detective Camera This camera had a viewfinder, it was "shuttered" to allow/block light which allowed fast exposure to be taken instead of a blur. Small, portable but still used glass plate which made them Awkward, however you could insert multiple glass plates.
*George Eastman's Advancements "Kodak" New media for making an image without glass. Instead it used paper, which then was put into a photographic paper roll. Rolls of film could hold up to 100 images and the camera took photos easily as well as advanced the film quickly.
What are the major methods of making trick photography? Combining Images Perspective Tricks Motion Effects Cropping Digital Additions
What are the early images of people? Silhouette Camera Obscura Heliograph Daguerrotype Ambrotype Carte Photograph Detective Camera George Eastman's Advancements
*Combining Images Method of trick photography that merges two or more images into one image.
*Perspective Tricks Ex: Someone closer to the camera making it look like they are stepping on someone who is farther away from the camera.
*Motion Effects A picture of someone/something is taken while they are in motion with the shutter remaining on the camera.
