Not much snow here. After all the weather reports over the last couple of days I was expecting at least a few centimetres but we got next to nothing. Instead, we got the deep freeze. Currently -4 …. -12 with windchill. (also known as 24 and 10 for those of you south of the border)
Shot with the Panasonic LX5….I’ll have to post more from my shoot out with the LX5 and the P7100 soon, but right now there’s a hot cup of tea with my name on it…
A little Holga style tonight…
Joined a few friends on twitter for a new yearly photo project.
POTW52 is the name. As you may have guessed…Picture Of The Week….means one or two photos a week and in this case we’re following a monthly theme.
January is Black and White month. Win!
Join in if you’d like. Post a link and use the hashtag #potw52. Let’s have some fun this year :)
It could be because I’m pointing a camera at him yet again…..it could be because our little softie has taken a dislike to cold weather this year, but someone does not look very pleased…..
Don’t worry though, he still gets out and about….I still can’t explain how he got a grease patch on his back last week…..not sure that I want to either….
Question: When the bride walks through the door, where should the photographer be looking?
Hint: you’ve already seen the bride but there’s one person who’s been waiting all day for this moment….
At London’s Great Exposition in 1851, also known as The Crystal Palace Exposition, a new process, the wet collodion process was showcased.
Collodion, invented in 1846 by C. F. Schonbein, is a transparent, sticky substance created by dissolving nitrocellulose in ethyl alcohol and ethyl ether. This substance dries into a tough, transparent skin that was used as a surgical dressing.
In 1851 Fredrick Scott Archer began using collodion on glass plates in photography as an alternative for egg whites (albumen).
The wet collodion process produced sharp images with exposure times as short as five seconds, an innovation which made photography more practical for mass consumption. The one downside to this process…it had to be completed immediately. The plate had to be made, exposed and developed before anything could dry out.
Photographers today may complain about the amount of gear they have to carry around but photographers using the wet collodion process had to carry around their camera gear and a complete darkroom in order to create their images.
Here’s how they did it:
- A mixture of collodion and potassium iodide is used to evenly coat a glass plate (Ambrotype) or a black enameled iron plate (tintype or ferrotype).
- The plate is sensitized by being dipped into a bath of silver nitrate.
- Next, it is exposed while still damp and then developed using a ferrous sulfate based developer, fixed using potassium cyanide or sodium thiosulfate, washed and finally dried.
All of this had to be completed before the emulsion was able to dry.
The wet collodion process creates a negative image. When glass was used the back of the glass was covered with black paper, felt or simply black varnish. This made the image appear as a positive. This image, the Ambrotype, was often covered with another piece of glass for protection and then put into a metal case.
The cheaper tintype also created a negative image but because the plate itself had a dark enameled coating it appears to be positive. These positives could be produced more quickly, placed in a paper frame and sold.
Ambrotypes were common from 1852 to 1890 but the cheaper Tintype was in use from 1855 to 1930.
I got lucky last week on my day off and finally had a sunny, rain free day on my day off. So of course I immediately grabbed my gear and headed for the park. Judging by this guy’s haul I wasn’t the only one having a good day..
