Brooklyn Historical Museum

Visiting the Brooklyn Historical Museum was a great experience. We looked at different types of Daguerreotypes photos. Daguerreotype was the first successful photographic process. Depending on the angle view and the color of the surface reflected into it, the image can change from a positive to a negative. A Daguerreotype is a picture with direct-positive process that creates high detailed image on the sheet of copper plated. A thin coat of silver is used to block the negative.  This process was tough to maintain because you first have to clean and polish the surface until it looked like mirror. Then the plate would be closed inside a box until yellow rose appear. After being exposed to the light, the plate was made over hot mercury until the image appears. Although you can have problem with the image coming out correct, using salt and tones with gold chloride will fix the detail of the image. Digital photos are different than Daguerreotypes when comes to the process and features.  Digital photos you have pixels that sharpen the image. When it deals with exposure of digital photos are much faster than Daguerreotype. To take a Daguerreotype photo you would have to wait a least 30 minutes. Also, Digital photos have flash, zoom, production, enhancing and resolution.
