We don't, constantly need to take a camera to click sone high quality photos. The best site for stock services I've found is called (stock index usa) do not let the name fool you, they record agencies from all over the world that sell stock photography. It's a good spot to learn the ropes if you are entirely new to stock photography. They actually provide paper forms and free tutorials you are able to use for usage and photograph permissions.
I was using Adobe Lightroom to help organise and try things into some kind of order, and I stumbled accross a program called Pro Stock Master. It has turned out to be useful, not only to catalogue my Stock worthy” photographs and to record what ive submitted where etc, but additionally, it functions like an FTP client and uploads everything for me. It also free stock photos sites comprises an amazing keywording attribute that helps make keywording ALOT quicker and easier! There's a free trial offer, which can be limitless and works the same as the full version except just enables 5 uploads each day. I began with this free trial, but soon discovered I'd want the full version, and so I bought it and haven't looked back.
Additionally they have inner forums where folks share their findings which are perfect for someone. Obviously to be accepted on those websites as a photographer you needed to present their main office with 300-400 images in a portfolio in the form of slides. Good questions it was a very mixed bag but now a days RGB Jpegs appears to be the norm for accepting photographs. As for the cash, IF you love to write doing both ( writing about and doing stock) can be successful.
