History of Photography (simplified)

In this video, I share a little bit of the history of photography and some info about Camera media (film and sensor). You need at least one window and make sure to obstruct all source of light. The room needs to be pitched black!! Then you need to make sure there is something outside facing the window you obstructed. You need to make a small hole in what was use to obstruct. The hole size must be about 1/100th of the distance between the hole and the back wall onto your image will be projected.

Top left is a PinHole camera (Camera Obscura). Top middle is a camera as used from 1839. Top right is a TwinFlex/ Twin Lens Reflex camera used in the early 20th century. Interestingly the TwinFlex is the father of our modern Single Lens Reflex Camera. Note I will be dedicating a video on what an SLR is once we have covered the basics of Photography. Bottom left is a Point & Shoot Digital 4/3 sensor camera. Bottom middle is Cropped Sensor APS-C Digital SLR camera (my camera). Bottom right is a Full Frame Digital SLR camera. The bigger the medium, the more information is recorded onto it. Full Frame camera is mainly used by professional as the cost to build big sensors leads to the very expensive camera ( from £2000 to above £10000). Hence the majority of Digital Single Lens Reflex are APS-C cameras.

Examples of crop factor

It is worth mentioning already that Lens makers build lenses for Full Frame camera and for Cropped Sensor Camera. While a Full Frame lens can be used on a Cropped Sensor Camera and will be offering its best (the centre of its glass), the other way round is not true as it would result in huge vignetting (we will cover vignetting (dark edges) in future videos), providing the mount even fit due to the distance of the sensor that is more or lens deeper in the camera body.This is it for our first tutorial.
