Monochrome sensors At it's core, the imaging sensor in a modern digital camera can be thought of as an array of very tiny solar panels. Solar panels work because photons carry energy. A charge builds up in each "pixel" of the sensor as an analog charge ... but this is converted to a digital value. This process can be used to explain how a camera ...

If you are referring to the centre part of the camera, with the two rails and the silver dot surrounded by black plastic - no, you do not need to remove the cap. This is known as a hotshoe. Its purpose is to allow you to connect an external flash and allows the camera to ...

One thing that hasn't been pointed out here is the difference between 'incident light' (the light falling on the subject) and 'reflected light' (the light bouncing off the subject). Your camera can only measure reflected light, which means it will depend on the colour and shade of the subject, whereas incident light is always consistent given a consistent ...

The claim is 'half true'. Very early photographs did take hours of exposure, but by the time the first portraits were being taken, that was down to 15 minutes or so. A long time to be sitting still, of course, but the sitters were aided in the same way as for painted portraiture, they had head- & arm-rests to enable them to hold a pose for this amount of ...

There are some very good online resources, but the free ones tend to be aimed at someone who is just beyond the basics. For a systematic beginning approach, I think a couple of basic books are much better at being structured and covering all of the beginning basics. Peterson's Understanding Exposure is probably the most recommended photography book anywhere....

All Lumix G series lenses are for the Micro Four Thirds system. From the listing for the LUMIX G 42.5mm F1.7 ASPH (H-HS043) at Panasonic's website:

The Five Key Steps to improving your photography: Step 1: Confirm you understand the "Exposure Triangle", and how shutter speed, aperture, and ISO all interact to produce a given image. This follows on into understanding motion blur [long shutter times], and depth of field [Smaller (bigger number) apertures allowing more of the scene to be in focus]. ...

Robert Cornelius supposedly took the first portrait photograph in America, a self protrait. According to his Wikipedia article: "Cornelius's image—which required him to sit motionless for 10 to 15 minutes—is the oldest known intentional photographic portrait of a human made in America, preceded by at least some months by portraits taken by Hippolyte ...

Camera's do not "see" color. They record brightness values. That's it. Each location on a camera's sensor that records the amount of light that falls on it for a given period of time is called a photosite. Photosites are often called sensels or mis-labeled pixels. Pixels are the smallest unit in a record of what a digital camera measures, but ...

The camera lens focuses the light reflected from the distant object onto the camera sensor. The light picks up the colors of the various colored patterns of the image (red things reflect red light, etc.) The camera sensor has a grid of pixels (for example, a 24 megapixel sensor is 6000x4000 pixels, 24 million of them). These camera sensors have red and green ...

Hours, no, but several minutes, yes. Photographers would use "posing stands" to help people keep their position:

This fact is true. And the reason is the light sensitivity of "film". Think about ISO 3 (or probably even less). Also fact about aperture which these days was to so small, probably around f11 (because of the quality of the glass). And the light in studios was no so powerful as contemporary one.

If you do not own any equipment I would look into buying a used dslr. If you can find a canon 600d with the 18-55 and 55-250 kit lenses you have a great start, any other similar kit would do as well. Spend some time inside figuring out the settings. Then go out and take pictures. My sugestion is go out with the intention to take 24 pictures so make them ...

The job of the lens is to create an image of the outside by projecting it on the surface of film or digital image sensor. To accomplish, light from objects traverse the transparent lens. The shape (figure) of the lens and the density of the lens material cause these image forming rays to alter their direction of travel. We can draw a trace of these emerging ...

Most of the other answers are perfectly valid. Another aspect to be considered is that -each- of the frames can be sold individually and exclusively to different buyers. You are selling the image, not the event.
