Raw vs Jpeg

Hello my name is Mark and I'm in the Photography Class in the Darca High School named after Makism Levi in Lod, And in the next post I will write about the diffrent digital tpyes file.

(1) What is Digital file?

So Digital file is a "title" for the most cammon file type and it discrbe the characteristics of files produced from the digitization of original record materials at NARA (National Archives and Records Administration). So NARA is part of USA government that responsible for maintaining and publishing the legally authentic and authoritative copies of acts of Congress, presidential directives, and federal regulations. NARA also transmits votes of the Electoral College to Congress.

(2) What are the differences betwen RAW File and JPEG File?

What is RAW file?

RAW file is a photo file that known as the best photo file for it's quality in the entire world. Because the speical processing of the data in the file.

What is JPEG file?

JPEG (Joint Photographic Experts Group) file is a most cammon photo file and the esaiest to work with it on the photoshop. 

So what is the differences betwen RAW File and JPEG (Joint Photographic Experts Group) File:
The main difference is the quality of the images between the RAW file and JPEG file, The Raw has better quality because instead of processing the images captured by the camera, the data is left unprocessed and uncompressed until it is opened with a computer program.
the process that the JPEG file uses is a digital print of the image on the camera sensors.

Hello my name is Mark and I'm in the Photography Class in the Darca High School named after Makism Levi in Lod, And in the next post I will write about the "100 years of negative in Photography"




(1)What are the differences betwen Daguerreotype and Calotype?

Awnser: The differences betwen Daguerreotype and Calotype are the materials that used to capture the image on the picture. The Calotype can duplicate the image and Daguerreotype can't. The Calotype was more cheaper not like the Daguerreotype.                 

                                                           THE CALOTYPE EXAMPLE

(2) Give 3 Camera types in the 20th century and explean thier advantages

Awsner: First Camera that I find is Instamatic Camera. Instamatic Camera is easy to use Camera that developed in early 1963 and it cost only 13 dollars (very chip price for those days) so it first low-cost Photography Camera for the use of the mass pepole.

                                                               Source of the image

Secend awsner: Secend Cmaera that I find is Nikon F it is the first SLR Camera of Nikon Company.

and Specially modified Nikon F cameras were used in space in the early 1970s aboard the Skylab space station.

(SLR meaning: SLR is single-lens reflex camera that uses a mirror and prism system. That perxzkjhmits the photographer to view through the lens and see exactly what will be captured)

                                                            Source of the image 

Third answer: Third Camera that I find it is Rapatronic camera. this is a high speed camera capable of recording a still image with an exposure time as brief as 10 nanoseconds.

Weegee camera what is this?

Awsner: Weegee use Pacemaker Speed Graphic (4x5) camera to take photo’s in one moment. That type of camera was developed between years 1947-1970, that camera use this types of formats 2¼ x 3¼, 3x4, 4x5. This camera was built from Mahogany/metal body. Coated lenses, lenses in shutters, body release, folding infinity stops. Side mounted rangefinder replaced by top rangefinder on 4x5" Graphics in 1955. Most Pacemakers have the Graflok back. The Graflex back (usually found on the "Graflex" SLR cameras) was an option on some Pacemaker models. Newly designed focal plane shutter. The shutter table of the old cameras with 24 speeds was changed to 6 speeds in this camera. Focal plane shutter.

(3) What is The Decisive Moment?

Awsner: The Decisive Moment is that time when the picture and the meining beside that has a perfect synergy on the felling level. And from technical side The decisive moment is picture on hige vaule of shutter. And because it the world of photograhpy can take photos in one moment and didnt need a preporation.
