AboutDavid Barry Expertise I have a lot of experience in most traditional forms of photography, so I`m quite knowledgeable about things like camera types and formats, techniques, exposure, film types, colour, filters, lighting, standard colour and black and white developing and printing.
I do not make recommendations about brands or models, and I am not a camera technician so I may not be able to tell you what is wrong with your equipment if it`s not working .
I also know a little about digital photography and imaging with scanners and digital cameras, so ask me and I will answer if I can.

Question What was the first camera ever made and who invented it i looked online and i got a few different answers. Also wondering how a old camera works compared to a new digital camera
Answer This all depends on your exact definition of camera.
I can't say for sure about the very first camera, but the principle of the camera was actually perceived as far back as the Greeks and the Romans and later referred to by people such as Leonardo da Vinci in the 15th century.
This was the 'camera obscura' which was basically a room or a box with a small hole in one side where light shines through onto the opposite side and forms a faint and vague image. Painters could then trace over that image and draw a rough outline on which to base their painting.
But probably more relevant to 'modern' photography, was in the 16th and 17th centuries when lenses were starting to be used in the camera obscura to focus the rough image to a more distinct one. These then evolved to more 'portable' and 'compact' versions through the late 1800s and into 1900s.
The main difference between the earliest cameras and today's digital marvels, was their large size (having to be mounted on a tripod), their lack of speed and efficiency, and lack of precision in the lens and mechanisms. The old cameras were very basic and mechanical (using springs, gears, and other crude mechanisms) tools.
The digitals of today are so compact, quick, simple and produce exceptionally good quality at an affordable price.
Digital cameras use the latest electronic technology of very small computer microchips.
But the principle of how cameras work has basically always been the same:
A box with a hole in one side, with a lens to focus the light coming through the hole onto the opposite side, where there is a light-sensitive material or device to record the image. Only the technology in making it happen has changed.
