The plate is covered in a light sensitive compound, containing Silver Halide crystals.
When light falls on the Silver-halide, it causes the silver atoms to clump together.
When developed with chemicals, the silver is left behind, causing dark areas where light has fallen. This makes a negative image, where light is dark and dark is light.
To get a positive print, simply shine light through the developed plate onto paper covered in the same Silver-halide compound.
After the same chemical process, the picture is reversed again giving the positive image.

What is it called when you remember everything?
photographic memory??
Why do plate tectonics have names?
It is a suitable name because tectonics comes from the Greek word tekton which means builder, and plate tectonics refers to the building of the features on Earth's surface due to deformation caused by plate movements...
What lithospheric plate is the largest?
The last person to answer was a complete and total idiot. The correct answer is the Pacific Plate.
What is a sentence for plate?
Plate tectonics is a theory that the Earth's crust is divided into many plates that glide over the mantle.He forgot to step on home plate so the umpire said he was out.That necklace is made of gold plate not solid gold.
Is a plate is dropped and shattered a chemical change?
A plate dropping and shattering is a physical change. It is not a chemical change, as the material used in making the plate doesn't change.
what is the chemical used for making photographic plate?
For photographic plates silver halides are used.
What did Robert Cornelius make?
photographic plate
What ray does not affect the photographic plate?
Gamma rays do not affect the photographic plate as they are highly penetrating and pass through without creating an image.
What is computer output microfilm?
Output to a photographic plate.
What are the advantages of a CCD over a photographic plate?
Instantaneous results. The primary advantage of the photographic plate over CCDs is image quality--an 8x10 plate carries a lot more image information than a CCD can capture.
Why was Becquerel shocked by his results when the photographic plate from the drawer was developed?
Becquerel was shocked because the photographic plate had fogged up even though it was stored in a dark drawer, leading him to realize that the uranium on the plate was emitting radiation that was able to penetrate the drawer and affect the plate. This discovery led to the development of the field of nuclear physics.
What is an early photographic process using silver plate developed in mercury vapour?
Daguerreotype
What are all Louis Lumiere's inventions?
All Louis Lumière's inventions are the photographic dry plate caled blue label, photographic machines, and the most important the cinematographe
A daguerreotype was an early photographic method created using a?
copper plate coated with silver iodide
What is an albertype?
An albertype is a picture printed from a form of gelatine plate produced by means of a photographic negative.
What percentage of the light falling on a typical photographic plate from a telescope is actually used to record an image on this plate?
Typically, only about 1% of the light that hits a photographic plate from a telescope is actually used to record an image. The rest of the light is lost due to reflection, absorption, and other inefficiencies in the system. Innovations like digital sensors in modern telescopes have increased this efficiency significantly.
Define radio activity?
emitting from radioactive elements which can cause fogging photographic plate is called radioactivity
