Hey guys I got a few questions regardding stock photos online. I am kinda interested into uploading pics for sale on istock Here are my questions: 1) what are stock photos composed of? Like what are stock photos supposed to be like? 2) Is there really that big of a "market" for them? Say if i have 20 up on istock, how long do you think itll take for me to sell my first pic? 3) What aer some example subjects that I should look out for to take pictures of? 4) Why do they say DO NOT sharpen images you plan to upload to sell for stock? Thanks! Any other info you could give me about stock photos would be great!
