I’m not sure if they are even used anymore, but back in the day engineers used spark cameras to capture very brief timescale events.
For a camera with a shutter, the shutter is in T (time) mode, in a dark room. For view cameras, the lite-tite dark slide on film holders is pulled out. Sparks in air generally do not give a uniform spectral (white light) distribution. Electronically triggered flash lamps were a major upgrade. Triggering a spark discharge in air was usually done by manually discharging a capacitor bank, so synchronizing with a shutter was difficult.Mech_Engineer said:When you call it a "spark camera," what exactly do you mean? Do you mean a conventionally shuttered camera with a fast flash which exposes the object while the shutter is open?
Spark cameras use a sensor called a complementary metal-oxide-semiconductor (CMOS) sensor to capture images. This sensor converts light into electrical signals, which are then processed to create an image.
Spark cameras use advanced image processing algorithms and high-quality lenses to produce high-resolution images. They also have features such as autofocus and image stabilization to improve the overall quality of the images.
Spark cameras use a combination of contrast detection and phase detection autofocus systems. These systems use information from the CMOS sensor to quickly and accurately focus on the subject in the image.
Spark cameras can connect to devices using a variety of methods, including Wi-Fi, Bluetooth, and USB. They also have the ability to transfer images wirelessly to compatible devices.
Spark cameras typically have built-in memory and also have the option to use memory cards for additional storage. They can also transfer images to external storage devices or cloud storage services.
