Lastly, let's take a look at other imaging devices and compliment products of cameras.
We were shown the Magic Lantern (Laterna Magica). Magic Lantern is a image projector used in the early days. Candles, combustion gases and later on, lamps are the various light sources used to power the Magic Lantern
The photo below shows the glass slide (lantern slide) that is inserted into the Magic Lantern. The slide will be projected onto the screen if there's adequate light. The process of changing a slide is manual which requires pulling out the slide, replacing a new slide to be projected and inserting it back.
This is the spot where the lamp is located. The gases are fed to the lamp and holes at the bottom provides oxygen supply.
Below is the newer version of image projectors. This is powered electronically and the transition of slides is done automatically with a touch of a button.
Here are some of the repair tools and the repair station. There include small size tweezers, test pens and other tools (no idea what they're called).
Right till the very end of the museum, we entered the dark room. Here's the room where the photos are treated and washed. Different chemical components used produces different results. If I'm not mistaken, dogging and burning are also done in the dark room. The photos washed are hang to dry.
Lastly, we have "Photoshop" of the early days. I was told that retouching of the images can be done by using a pencil and slightly spotting the negative and then process the photo again.
Technology has certainly changed. Devices ran electronically which makes it a lot safer compared to the use of combustion gases and oil lamps. Things are also more convenient. At a touch of a button tasks are done automatically rather than manual labour and process. We should feel fortunate to be living in the era of the 21st century.
